New dwarf galaxy found orbiting the Milky Way

Astronomers at the University of Cambridge have announced the discovery of "Crater 2" – a new member of the Local Group.

A never-before-seen galaxy has been spotted orbiting the Milky Way. With a diameter of around 7,000 light years, it becomes the fourth largest known satellite of the Milky Way, surpassed only by the Large Magellanic Cloud, Small Magellanic Cloud and the Sagittarius Dwarf. Known as "Crater 2", it was discovered by the University of Cambridge's Institute of Astronomy.

Crater 2 is extremely faint compared to other members of the Local Group. Its diffuseness allowed it to remain hidden, but it was identified in recent data from the VST ATLAS survey. A computer algorithm processed images taken by the Very Large Telescope in Chile, pinpointing regions that might have unusual clustering of stars. This revealed an entire new satellite galaxy, located 380,000 light years away.

"This is indeed a very rare discovery. A galaxy like Crater 2 is a sort of invisible object," says Dr. Vasily Belokurov. "We have found many similar objects in the last 10 years, but never such a large beast. It is orders of magnitude less luminous compared to most objects of similar size. It is extremely diffuse. We believe it was born that fluffy. But why, we do not yet know."

If the brightness of Crater 2 were increased by 1,000 times, its angular diameter would be twice that of the full Moon, as shown in the illustration below. This suggests there might be other dark neighbours lurking nearby. Indeed, Dr. Belokurov and his team are now using their technique to hunt for additional objects that might have been missed. It is hoped these discoveries could lead to a better understanding of the origin and evolution of our own galaxy, the Milky Way.

"In the last two years alone, the number of known Milky Way satellite galaxies has doubled, largely thanks to the Dark Energy Camera on the Blanco 4m telescope in Chile," Dr. Evan Kirby, assistant professor at Caltech, who was not involved in the research, told the Huffington Post. "These galaxies are intense concentrations of dark matter," he added. "If there's a place in the universe where we can look to learn about dark matter, it's dwarf galaxies. How is it distributed? What is it made of? Future observations, especially spectroscopy, will help answer those questions."

Crater 2 seems to be aligned in 3-D with the globular cluster Crater, the pair of dwarfs Leo IV and Leo V and the classical dwarf Leo II. The researchers argue that such arrangement "is probably not accidental and, in fact, can be viewed as evidence for the accretion of the Crater-Leo group." Their study is published in Monthly Notices of the Royal Astronomical Society.

NASA seeks proposals for deep space habitation prototypes

NASA is inviting proposals for the development of prototype space habitats that will give astronauts a place to call home during long-duration missions supporting the agency's Journey to Mars program.

 

nasa journey to mars

 

NASA's solicitation – Next Space Technologies for Exploration Partnerships-2 (NextSTEP-2) – is a follow-on to the NextSTEP Broad Agency Announcement (BAA) released in October 2014, requesting proposals for concept studies and technology development projects in the areas of human habitation, advanced propulsion and small satellites.

NASA's Orion crew spacecraft and Space Launch System are the agency's first major components for establishing a human presence in deep space. With these transportation systems progressing toward their maiden flight in 2018, the agency is now looking toward investments in deep space habitation, the next major component of human space exploration beyond low-Earth orbit.

NextSTEP is a public-private partnership model that seeks commercial development of deep space exploration capabilities to support more extensive human spaceflight missions in the proving ground of space around the Moon, known as cislunar space, and to enable transit to Mars. This partnership model enables NASA to obtain innovative concepts and support private industry commercialisation plans for low-Earth orbit.

"NASA is increasingly embracing public-private partnerships to expand capabilities and opportunities in space," said Jason Crusan, director of NASA's Advanced Exploration Systems (AES) division. "Our NextSTEP partners commit their own corporate resources toward the development – making them a true partner in the spaceflight economy."

Under Appendix A of the NextSTEP-2 Ominbus BAA, the agency is providing the opportunity for additional contractors to join those already under contract through the previous NextSTEP BAA. Proposals will include plans for an evolvable approach to long-duration deep space habitation and the development of full-size, ground prototype habitat units, no later than 2018.

There will be a chance to ask questions about this program during an industry forum on 25th April 2016. Eligible applicants from U.S. companies, universities and non-profit organisations must submit proposals electronically by 15th June 2016.

High-speed probes could travel to Alpha Centauri within 20 years

A group of scientists has announced "Breakthrough Starshot" – a program to develop a fleet of nanocraft probes able to reach the nearest star within 20 years and return images to Earth.

 

 

 

Science philanthropist Yuri Milner has announced a space research and engineering program called "Breakthrough Starshot". This aims to demonstrate a proof of concept for using light beams to push "nanocraft" probes to 20 percent of light speed. A possible fly-by mission could reach Alpha Centauri within 20 years of being launched, beaming back images and data four years after that.

Pete Worden – the former director of NASA's AMES Research Center – will lead the program, with advice being provided from a committee of world-class scientists and engineers. The board will consist of Stephen Hawking, Yuri Milner, and Mark Zuckerberg.

The Alpha Centauri star system is 25 trillion miles (4.37 light years) away. With today's fastest spacecraft, it would take about 30,000 years to get there. Breakthrough Starshot would aim to develop solar sails pushed by light beams, allowing tiny probes to fly over 1,000 times faster – taking advantage of exponential advances in certain areas of technology since the beginning of the 21st century.

 

closest stars

 

"If we are to survive as a species, we must ultimately spread out to the stars," Professor Hawking said in a BBC interview. "Astronomers believe that there is a reasonable chance of an Earth-like planet orbiting one of the stars [in] the Alpha Centauri system. But we will know more in the next two decades from ground-based and space-based telescopes. Technological developments in the last two decades and the future make it possible in principle within a generation."

If an Earth-size planet is lurking in the Alpha Centauri system, Breakthrough Starshot will try to aim its probes within 1 Astronomical Unit (150 million kilometres or 93 million miles) of it. From this distance, its cameras could potentially capture an image of high enough quality to resolve surface features. The spacecraft fleet would consist of 1,000 probes, and each craft, called a "StarChip", would be a very small, centimetre-sized device weighing only several grams. They would be propelled by arrays of ground-based lasers of up to 100 gigawatts. Each tiny spacecraft would transmit data back to Earth using a compact on-board laser communications system.

 

laser array

 

Each probe would comprise two main parts:

StarChip: Moore's law has allowed a dramatic reduction in the size of microelectronic components. This creates the possibility of a gram-scale wafer, cameras, photon thrusters, power supply, navigation and communication equipment, constituting a fully functional space probe.

Lightsail: Advances in nanotechnology are producing thinner and lighter metamaterials, promising to enable the fabrication of metre-scale sails no more than a few hundred atoms thick. These could be folded prior to launch, then unfurled once in orbit.

The rising power and falling cost of lasers, consistent with Moore's law, will lead to significant advances in light beaming technology in the coming years. Breakthrough Starshot aims to leverage this trend, bringing economies of scale to the astronomical scale. A StarChip could be mass-produced at the cost of an iPhone and be sent on missions in large numbers to provide redundancy and coverage. The light beamer would be modular and scalable. Once it is assembled and the technology matures, the cost of each launch is expected to fall to a few hundred thousand dollars.

 

nanocraft to alpha centauri

 

The research and engineering phase is expected to last about two decades. Following that, development of the ultimate mission to Alpha Centauri would require a budget comparable to the largest current scientific experiments, and would involve:

• Building a ground-based, kilometre-scale light beamer at high altitude in dry conditions
• Generating and storing a few gigawatt hours of energy per launch
• Launching a "mothership" carrying thousands of nanocrafts to a high-altitude orbit
• Taking advantage of adaptive optics technology in real time, to compensate for atmospheric effects
• Focusing the light beam on the lightsail to accelerate individual nanocrafts to the target speed within minutes
• Accounting for interstellar dust collisions en route to the target
• Capturing images of a planet, and other scientific data, and transmitting them back to Earth using a compact on-board laser communications system
• Using the same light beamer that launched the nanocrafts to receive data from them four years later.

These and other system requirements represent significant engineering challenges. However, the key elements of the proposed system design are based on technology either already available or likely to be attainable in the near future under reasonable assumptions. As with previous major projects – such as the International Space Station (ISS) and Large Hadron Collider – global co-operation and support would be needed.

As the technology required for interstellar travel matures, additional opportunities could emerge, including the following:

• Contribution to Solar System exploration
• Using the light beamer as a kilometre-scale telescope for astronomical observations
• Detection of Earth-crossing asteroids at large distances.

Astronomers believe there is a reasonable chance of an Earth-like planet existing in the habitable zones of Alpha Centauri's three-star system. A number of scientific instruments – both ground-based and space-based – are being developed and enhanced, which will soon identify and characterise planets around the nearest stars. A separate initiative will support some of these projects.

 

alpha centauri

 

Breakthrough Starshot is a long-term project that could run until the 2050s or later. It aims to foster an open and collaborative environment that is:

• Based entirely on research that is in the public domain
• Committed to publishing new results
• Dedicated to full transparency and open access
• Open to experts in all relevant fields, as well as the public, to contribute ideas.

During its announcement, Milner's team outlined the biggest challenges facing the mission. These include: developing a two megapixel camera able to be miniaturised to the sub-gram scale; a tiny plutonium-238 or Americanium-241 battery; a thin and strong lightsail able to survive extreme acceleration; and a laser array with sufficient focus to bypass atmospheric turbulence.

It is hoped that a large swarm of 1,000 spacecraft will have "safety in numbers" and will compensate for any losses caused by interstellar dust collisions en route to their target. The team estimates that each square centimetre of frontal cross-section will impact at high speed with about a thousand particles of 0.1 microns or larger. New materials will be needed for the sails and other components to withstand these bombardments, in addition to coping with decades of cold vacuum.

As well as these technical hurdles, Breakthrough Starshot will need substantial amounts of funding – between $5 and $10 billion. Milner himself has donated $100 million for the initial research. If successful, the first craft could launch about 20 years from now.

"The human story is one of great leaps," said Milner in the press conference. "Today, we are preparing for the next great leap... to the stars."

"We take inspiration from Vostok, Voyager, Apollo and the other great missions," said Pete Worden. "It's time to open the era of interstellar flight."

"Earth is a wonderful place, but it might not last forever," said Professor Hawking. "Sooner or later, we must look to the stars. Breakthrough Starshot is a very exciting first step on that journey."

New search for signals from 20,000 star systems begins

The SETI Institute has inaugurated a greatly expanded hunt for deliberately produced radio signals that would indicate the presence of extraterrestrial intelligence. Over the next two years, it will scrutinise the vicinities of 20,000 red dwarf stars.

"Red dwarfs – the dim bulbs of the cosmos – have received scant attention by SETI scientists in the past," says Institute engineer Jon Richards. "That's because researchers made the seemingly reasonable assumption that other intelligent species would be on planets orbiting stars similar to the Sun."

This conservative assessment was bolstered by the argument that few planets were likely to be found in the habitable zone of a red dwarf star, simply because that zone is far narrower than for brighter stars like our Sun. Additionally, any worlds that were in this zone would be orbiting so close to their suns that they would quickly become tidally locked – with one hemisphere perpetually facing the star. It was assumed that this would produce a planet that was intolerably hot on one side, and brutally cold on the other, ruling it out as an abode for life.

However, more recent research has indicated that, if these worlds have oceans and atmospheres, heat would be transported from the lit side to the dark, and a significant fraction of the planet would be habitable. In addition, exoplanet data have suggested that somewhere between one sixth and one half of red dwarf stars have planets in their habitable zones, a percentage comparable to, and possibly greater than, that of Sun-like stars.

"Significantly, three-fourths of all stars are red dwarfs," explains SETI astronomer Seth Shostak. "That means that if you observe a finite set of them – say the nearest twenty thousand – then on average they will be at only half the distance of the nearest twenty thousand Sun-like stars."

Closer stars mean that any signals would be stronger. Also, red dwarfs burn for a period of time that's greater than the current age of the universe: every red dwarf ever born is still shining today. They are, on average, billions of years older than Sun-like stars.

"This may be one instance in which older is better," Shostak says. "Older solar systems have had more time to produce intelligent species."

The search is being conducted on the SETI Institute's Allen Telescope Array, located in the Cascade Mountains of northern California. This grouping of 42 antennas can observe three stars simultaneously.

"We'll scrutinise targeted systems over several frequency bands, between 1 and 10 GHz," says Institute scientist Gerry Harp. "Roughly half of those bands will be at so-called 'magic frequencies' – places on the radio dial that are directly related to basic mathematical constants. It's reasonable to speculate that extraterrestrials trying to attract attention might generate signals at such special frequencies."

The new red dwarf survey is planned to take two years. Targets are being chosen from a list of about 70,000 red dwarfs compiled by Boston University astronomer Andrew West. The search will also incorporate relevant new data generated by NASA's Transiting Exoplanet Survey Satellite (TESS). Due for launch in August 2017, TESS will examine nearby stars, including red dwarfs, for planets.

SpaceX lands Falcon 9 rocket on a floating drone ship

In a historic achievement, private U.S. aerospace company SpaceX has successfully landed a Falcon 9 rocket – part of the CRS-8 mission – on a floating drone ship for the first time. This follows their earlier milestone in December 2015 when a similar attempt resulted in a landing on solid ground.

CRS-8 is a cargo resupply mission to the International Space Station. It was the tenth flight for SpaceX's uncrewed Dragon cargo spacecraft and the eighth operational mission contracted to NASA under a Commercial Resupply Services contract, which followed the retirement of the Space Shuttle fleet back in 2011. Several previous attempts to land at sea have all resulted in failure. On this occasion, however, the first stage successfully landed on the floating platform named Of Course I Still Love You, 300 km from the Florida coastline, as seen in this video.

Propellant costs for a rocket are much lower than the costs of hardware. The ability to re-use rockets – instead of them being discarded and burning up on reentry – could therefore slash the cost of spaceflight. An ocean landing requires less fuel than a ground landing, due to flight paths being more direct and less curved, which provides yet another efficiency improvement and makes this latest achievement even more notable.

ExoMars mission lifts off

The ExoMars Trace Gas Orbiter has been successfully launched from Baikonur in Kazakhstan. It will study methane on Mars, which could reveal whether life currently exists on the planet.

The first of two joint ESA–Roscosmos missions to Mars has begun a seven-month journey to the Red Planet, where it will address unsolved mysteries of the planet’s atmosphere that could indicate present-day geological – or even biological – activity.

The Trace Gas Orbiter and the Schiaparelli entry, descent and landing demonstrator lifted off on a Proton-M rocket operated by Russia’s Roscosmos at 09:31 GMT yesterday morning from Baikonur, Kazakhstan. Following separation of the Proton’s first and second stages, the payload fairing was released. The third stage separated nearly 10 minutes after liftoff. The Breeze-M upper stage, with ExoMars attached, then completed a series of four burns before the spacecraft was released at 20:13 GMT (21:13 CET). Signals from the craft, received at ESA’s control centre in Darmstadt, Germany, confirmed that the launch was successful and the spacecraft is in good health. The orbiter’s solar wings have also now unfolded and the craft is on its way to Mars.

“It’s been a long journey getting the first ExoMars mission to the launch pad, but thanks to the hard work and dedication of our international teams, a new era of Mars exploration is now within our reach,” said Johann-Dietrich Woerner, the Director General of ESA. “I am grateful to our Russian partner, who have given this mission the best possible start today. Now we will explore Mars together.”

“Only the process of collaboration produces the best technical solutions for great research results,” said Igor Komarov, General Director of the Roscosmos State Space Corporation. “Roscosmos and ESA are confident of the mission’s success.”

“We’re not only looking forward to the world-class science data that this mission will return, but it is also significant in paving the way for the second ExoMars mission, which will move our expertise from in-orbit observations to surface and subsurface exploration of Mars,” said Alvaro Giménez, ESA Director of Science.

 

 

 

The Trace Gas Orbiter (TGO) and Schiaparelli will travel to Mars together, before separating on 16th October at distance of 900,000 km (560,000 miles) from the Red Planet. Then, on 19th October, Schiaparelli will enter the Martian atmosphere, descending to the surface in just under six minutes. Schiaparelli will demonstrate key entry, descent and landing technologies for future missions, and will conduct a number of environmental studies during its short mission on the surface. For example, it will obtain the first measurements of electric fields on the surface of Mars that, combined with measurements of atmospheric dust, will provide new insights into the role of electric forces on dust lifting – the trigger for dust storms.

Meanwhile, on the same day, TGO will enter an elliptical four-day orbit, taking it from 300 km at its closest to 96,000 km at its furthest point. After a year of complex ‘aerobraking’, during which the spacecraft will use the planet’s atmosphere to lower its orbit slowly to a circular 400 km, its scientific mission to analyse rare gases in the atmosphere will begin.

Of particular interest is methane, which on Earth, points to active geological or biological processes. One of the mission’s key goals is to follow up on the methane detection made by ESA’s Mars Express in 2004 to understand the processes causing its generation and destruction, with an improved accuracy of three orders of magnitude over previous measurements.

TGO will also image features on the surface that may be related to trace-gas sources, such as volcanoes. In addition, it will be able to detect buried water-ice deposits, which, along with locations identified as trace gas sources, may influence the choice of landing sites of future missions. The orbiter will also act as a data relay for the second ExoMars mission – comprising a rover and stationary surface science platform, which is scheduled for launch in May 2018, arriving in 2019.

First detection of super-Earth atmosphere

NASA's Hubble Space Telescope has detected hydrogen and helium, but no water vapour, in the atmosphere of 55 Cancri e – the first time the atmosphere of a "super-Earth" has been analysed successfully.

 

 

 

For the first time, astronomers were able to analyse the atmosphere of an exoplanet in the class known as super-Earths. Using data gathered with the NASA/ESA Hubble Space Telescope and new analysis techniques, the exoplanet 55 Cancri e is revealed to have a dry atmosphere without any indications of water vapour. The results, to be published in the Astrophysical Journal, indicate that the atmosphere consists mainly of hydrogen and helium.

The international team, led by scientists from University College London (UCL), took measurements of the nearby exoplanet 55 Cancri e, a super-Earth with a mass of eight Earths. It is located in the planetary system of 55 Cancri, a star about 40 light-years from Earth. Using observations made by the Wide Field Camera 3 (WFC3) on board the NASA/ESA Hubble Space Telescope, the scientists were able to analyse the atmosphere in detail. The results were only made possible by exploiting a newly-developed processing technique.

"This is a very exciting result, because it's the first time that we have been able to find the spectral fingerprints that show the gases present in the atmosphere of a super-Earth," explains Angelos Tsiaras, a PhD student at UCL, who developed the analysing technique, along with his colleagues Ingo Waldmann and Marco Rocchetto. "The observations of 55 Cancri e's atmosphere suggest that the planet has managed to cling on to a significant amount of hydrogen and helium from the nebula from which it originally formed."

Super-Earths like 55 Cancri e are thought to be the most common type of planet in our galaxy. They acquired the name 'super-Earth' because they have a mass larger than that of the Earth, but are still much smaller than the gas giants in the Solar System. The WFC3 instrument on Hubble has already been used to probe the atmospheres of two other super-Earths, but no spectral features were found in those previous studies.

55 Cancri e, however, is an unusual super-Earth, as it orbits very close to its parent star. A year on the exoplanet lasts for only 18 hours and temperatures on the surface are thought to reach around 2000 degrees Celsius. Because the planet orbits its bright parent star at such a small distance, the team was able to use their new technique to extract key information about the planet, during its transits in front of the host star.

Observations were made by scanning the WFC3 very quickly across the star to create a number of spectra. By combining these observations and processing them through analytic software, the researchers were able to retrieve the spectrum of 55 Cancri e embedded in the light of its parent star.

"This result gives a first insight into the atmosphere of a super-Earth. We now have clues as to what the planet is currently like and how it might have formed and evolved, and this has important implications for 55 Cancri e and other super-Earths," said Giovanna Tinetti, also from UCL.

Intriguingly, the data also contain hints of the presence of hydrogen cyanide, a marker for carbon-rich atmospheres.

"Such an amount of hydrogen cyanide would indicate an atmosphere with a very high ratio of carbon to oxygen," said Olivia Venot, KU Leuven, who developed an atmospheric chemical model of 55 Cancri e that supported the analysis of the observations.

"If the presence of hydrogen cyanide and other molecules is confirmed in a few years time by the next generation of infrared telescopes, it would support the theory that this planet is indeed carbon rich and a very exotic place," concludes Jonathan Tennyson, UCL. "Although hydrogen cyanide, or prussic acid, is highly poisonous, so it is perhaps not a planet I would like to live on!"

Gravitational waves detected for the first time

In a historical scientific landmark, researchers have announced the first detection of gravitational waves, as predicted by Einstein's general theory of relativity 100 years ago. This major discovery opens a new era of astronomy.

For the first time, scientists have directly observed "ripples" in the fabric of spacetime called gravitational waves, arriving at the Earth from a cataclysmic event in the distant universe. This confirms a major prediction of Einstein’s 1915 general theory of relativity and opens an unprecedented new window onto the cosmos.

The observation was made at 09:50:45 GMT on 14th September 2015, when two black holes collided. However, given the enormous distance involved and the time required for light to reach us, this event actually occurred some 1.3 billion years ago, during the mid-Proterozoic Eon. For context, this is so far back that multicellular life here on Earth was only just beginning to spread. The signal came from the Southern Celestial Hemisphere, in the rough direction of (but much further away than) the Magellanic Clouds.

The two black holes were spinning together as a binary pair, turning around each other several tens of times a second, until they eventually collided at half the speed of light. These objects were 36 and 29 times the mass of our Sun. As their event horizons merged, they became one – like two soap bubbles in a bath. During the fraction of a second that this happened, three solar masses were converted to gravitational waves, and for a brief instant the event hit a peak power output 50 times that of the entire visible universe.

 

gravitational waves 2016 science black holes

 

The gravitational waves were detected by both of the twin Laser Interferometer Gravitational-wave Observatory (LIGO) detectors, located in Livingston, Louisiana, and Hanford, Washington, USA. The LIGO Observatories are funded by the National Science Foundation (NSF), and were conceived, built, and are operated by Caltech and MIT. The discovery was published yesterday in the journal Physical Review Letters.

Prof. Stephen Hawking told BBC News: "Gravitational waves provide a completely new way of looking at the Universe. The ability to detect them has the potential to revolutionise astronomy. This discovery is the first detection of a black hole binary system and the first observation of black holes merging. Apart from testing General Relativity, we could hope to see black holes through the history of the Universe. We may even see relics of the very early Universe during the Big Bang at some of the most extreme energies possible."

"There is a Nobel Prize in it – there is no doubt," said Prof. Karsten Danzmann, from the Max Planck Institute for Gravitational Physics and Leibniz University in Hannover, Germany, who collaborated on the study. In an interview with the BBC, he claimed the significance of this discovery is on a par with the determination of the structure of DNA.

"It is the first ever direct detection of gravitational waves; it's the first ever direct detection of black holes and it is a confirmation of General Relativity because the property of these black holes agrees exactly with what Einstein predicted almost exactly 100 years ago."

"We found a beautiful signature of the merger of two black holes and it agrees exactly – fantastically – with the numerical solutions to Einstein equations ... it looked too beautiful to be true."

"Scientists have been looking for gravitational waves for decades – but we’ve only now been able to achieve the incredibly precise technologies needed to pick up these very, very faint echoes from across the universe," said Danzmann. "This discovery would not have been possible without the efforts and the technologies developed by the Max Planck, Leibniz Universität, and UK scientists working in the GEO collaboration."

Researchers at the LIGO Observatories were able to measure tiny and subtle disturbances the waves made to space and time as they passed through the Earth, with machines detecting changes just fractions of the width of an atom. At each observatory, the two-and-a-half-mile (4-km) long L-shaped LIGO interferometer uses laser light split into two beams that travel back and forth along tubes kept at a near-perfect vacuum. The beams are used to monitor the distance between mirrors precisely positioned at the ends of the arms. According to Einstein’s theory, the distance between the mirrors will change by an infinitesimal amount when gravitational waves pass by the detector. A change in the lengths of the arms smaller than one-ten-thousandth the diameter of a proton can be detected; equivalent to a human hair's diameter over three light years from Earth.

"The Advanced LIGO detectors are a tour de force of science and technology, made possible by a truly exceptional international team of technicians, engineers, and scientists," says David Shoemaker of MIT. "We are very proud that we finished this NSF-funded project on time and on budget."

"We spent years modelling the gravitational-wave emission from one of the most extreme events in the universe: pairs of massive black holes orbiting with each other and then merging. And that’s exactly the kind of signal we detected!" says Prof. Alessandra Buonanno, director at the Max Planck Institute for Gravitational Physics in Potsdam.

"With this discovery, we humans are embarking on a marvellous new quest: the quest to explore the warped side of the universe – objects and phenomena that are made from warped spacetime," says Kip Thorne, Feynman Professor of Theoretical Physics at Caltech. "Colliding black holes and gravitational waves are our first beautiful examples."

Advanced LIGO is among the most sensitive instruments ever built. During its next observing stage, it is expected to detect five more black hole mergers and to detect around 40 binary star mergers each year, in addition to an unknown number of more exotic gravitational wave sources, some of which may not be anticipated by current theory.

Asteroid mining initiative announced by Luxembourg

The Luxembourg government yesterday announced a series of measures to position the country as a European hub in the exploration and use of space resources. Amongst the key steps undertaken will be the development of a legal and regulatory framework that provides certainty about the future ownership of minerals extracted from Near Earth Objects (NEO's), such as asteroids.

 

luxembourg asteroid mining future timeline

 

Luxembourg has become the first European country to announce its intention to establish a formal legal framework ensuring that private operators working in outer space can be confident about their rights to the resources they extract, i.e. rare minerals from asteroids. This legal framework will be designed in full consideration of international law. Luxembourg is eager to engage with other countries on this matter within a multilateral framework. Luxembourg will also invest in relevant R&D projects and consider direct capital investment in companies active in this field.

This initiative will nurture an exciting and entirely new space industry – offering unprecedented access to vast metal and mineral resources, for use in Earth orbit and beyond, stimulating economic growth and encouraging new horizons in space exploration.

Luxembourg already has a strong track record in related sectors, with satellite operator SES, established in Luxembourg 30 years ago and now a major global player in its field. The budget allocated to the space resources initiative will be part of the national space budget and will be defined in terms of Luxembourg's contribution to the next European Space Agency (ESA) multiannual budget, to be decided in December 2016.

 

 

 

Luxembourg's Deputy Prime Minister and Minister of the Economy, Étienne Schneider, commented: "Our aim is to open access to a wealth of previously unexplored mineral resources on lifeless rocks hurling through space, without damaging natural habitats. We will support the long-term economic development of new, innovative activities in the space and satellite industries as a key high-tech sector for Luxembourg. At first, our aim is to carry out research in this area, which at a later stage can lead to more concrete activities in space."

Former ESA boss, Jean-Jacques Dordain, will be an adviser. In a press conference, he said that asteroid mining was no longer science fiction; the basic technologies of landing and returning materials from space had essentially been proven: "Things are moving in the United States and it was high time there was an initiative in Europe, and I am glad the first initiative is coming from Luxembourg," he said. "It will give no excuse for European investors to go to California."

Yves Elsen, Chairperson of the Luxembourg Space Cluster stated: "Over the past three decades, Luxembourg has built up extensive know-how in world-class space related activities. Luxembourg can write history once again by further sustaining the attractiveness of the country for a host of next generation space activities."

Simon P. Worden, Chairman of the Breakthrough Prize Foundation said: "Humanity is on the verge of expansion into the solar system – and then beyond. Using the resources we find there is essential – not only for our expansion into space, but also to ensure continued prosperity here on Earth."

Chris Lewicki, President and CEO of Planetary Resources, commented: "We commend the Government of Luxembourg in leading the world by establishing this new resource industry, thereby enabling the economic development of near-Earth asteroid resources. Planetary Resources looks forward to working with Luxembourg."

Rick Tumlinson, Co-founder and Chair of the Board of Deep Space Industries, stated: "By opening up the resources of space, Luxembourg will help take the pressure off the Earth."

Giant cloud heading for Milky Way originated from within our galaxy

New observations of Smith's Cloud, which is predicted to collide and merge with our galaxy in 27 million AD, reveal that it originated from within the Milky Way. Like a boomerang effect, it now appears to be heading back to its galactic home.

Smith's Cloud – a vast cloud of hydrogen gas that is speeding towards the Milky Way – did not originate from intergalactic space, but was actually launched out of our own galaxy around 70 million years ago. That's according to a new study by astronomers at the Space Telescope Science Institute in Baltimore, Maryland, who used the Hubble Space Telescope to determine its location and trajectory with more precision.

It was previously believed that Smith's Cloud, which is 11,000 light years in length, crossed the immense void of intergalactic space on its long journey and was possibly a failed, starless dwarf galaxy. For either of these speculations to be true, it would need to contain mostly hydrogen and helium gas – not the heavier elements made by stars.

These new observations, however, looked at ultraviolet light from the bright cores of three distant galaxies, using Hubble's Cosmic Origins Spectrograph to see how this light was filtered through the cloud. The data revealed its chemical composition for the first time, confirming it to be as sulphur-rich as the Milky Way's outer disk.

"By measuring sulphur, you can learn how enriched in sulphur atoms the cloud is compared to the Sun," explained team leader Andrew Fox. Sulphur is a good gauge of how many heavier elements reside in the cloud.

This means that the Smith Cloud was enriched by material from stars, which could not happen if it were pristine hydrogen from outside the galaxy, or if it were the remnant of a failed galaxy devoid of stars. Instead, the cloud appears to have been ejected from within the Milky Way and is now returning back towards the galactic plane in a kind of boomerang effect.

"The cloud is an example of how the galaxy is changing with time," said Fox. "It's telling us that the Milky Way is a bubbling, very active place, where gas can be thrown out of one part of the disk and then return back down into another."

"Our galaxy is recycling its gas through clouds, the Smith Cloud being one example, and will form stars in different places than before. Hubble's measurements of the Smith Cloud are helping us to visualise how active the disks of galaxies are."

While this settles the mystery of the Smith Cloud's origin, it raises new questions: How did the cloud get to where it is now? What calamitous event could have catapulted it from the Milky Way, and how did it remain intact? Could it be a region of dark matter – an invisible form of matter – that passed through the disk and captured Milky Way gas? Answers to these questions may be found in future research.

Smith Cloud's is moving at nearly 200 miles per second (or about 700,000 mph) and is predicted to collide into the Perseus Arm by 27 million AD. This will trigger an intense burst of star formation where it hits, giving birth to as many as two million additional new stars. Fox and his team have published their study in the Astrophysical Journal Letters. The entry on our timeline has been updated to reflect their new findings.

Strong evidence of a ninth planet in our Solar System

Astronomers at the California Institute of Technology have found the strongest evidence yet that a ninth planet – or "Planet X" – is present in our Solar System, orbiting the Sun every 20,000 years.

 

ninth planet solar system 2016

 

Researchers at the California Institute of Technology (Caltech) have found evidence of a giant planet tracing a highly elongated orbit in the far distant reaches of our Solar System. The object, which has been nicknamed "Planet Nine", has a mass about 10 times that of Earth and orbits about 20 times farther from the Sun on average than does Neptune (which orbits the Sun at an average distance of 2.8 billion miles). With a semi-major axis of 300,000 light seconds, or about 0.01 light years, it would take this new planet an estimated 20,000 years to make just one full orbit around the Sun.

The researchers, Konstantin Batygin and Mike Brown, discovered the planet's existence through mathematical modelling and computer simulations but have not yet observed the object directly.

"This would be a real ninth planet," says Brown. "There have only been two true planets discovered since ancient times, and this would be a third. It's a pretty substantial chunk of our Solar System that's still out there to be found, which is pretty exciting."

Brown notes that Planet Nine, at 5,000 times the mass of Pluto, is sufficiently large that there should be no debate about whether it is a true planet. Unlike the class of smaller objects now known as dwarf planets, it gravitationally dominates its neighbourhood. In fact, it dominates a region larger than any of the other known planets, a fact that Brown says makes it "the most planet-y of the planets in the whole Solar System."

Batygin and Brown describe their work in the current issue of the Astronomical Journal and show how Planet Nine helps explain a number of mysterious features of the Kuiper Belt. The orbital correlations of six distant trans-Neptunian objects, pictured below, were key to their model. After they plotted the orbits of these and various other objects, they matched their simulations perfectly: "When we found that, my jaw sort of hit the floor," says Brown.

 

ninth planet solar system 2016

 

Batygin, an assistant professor of planetary science, comments: "Although we were initially quite sceptical that this planet could exist, as we continued to investigate its orbit – and what it would mean for the outer Solar System – we became increasingly convinced it is out there. For the first time in over 150 years, there is solid evidence that the Solar System's planetary census is incomplete."

In a couple of ways, this ninth planet – which seems like an oddball to us – would actually make our Solar System more similar to systems that astronomers are finding around other stars. Firstly, most of the planets around other Sun-like stars have no single orbital range – that is, some orbit at extremely close range to their host stars, while others follow exceptionally distant orbits. Secondly, the most common planets around other stars vary between one and 10 Earth-masses.

"One of the most startling discoveries about other planetary systems has been that the most common type of planet out there has a mass between that of Earth and that of Neptune," explains Batygin. "Until now, we have thought that the Solar System was lacking in this most common type of planet. Maybe we're more normal after all."

The team continue to refine their simulations and learn more about the planet's orbit and its gravitational influence on the Solar System. They believe their study will trigger a worldwide hunt by astronomers – both amateur and professional – to obtain the first direct visual images of Planet Nine. A new generation of observatories such as the James Webb Telescope may do just that. It might also be spotted in old images captured by previous surveys. Given its high mass, it is possible that various moons are there too.

"I would love to find it," says Brown. "But I'd also be perfectly happy if someone else found it. That is why we're publishing this paper. We hope that other people are going to get inspired and start searching."

Brown, well known for the significant role he played in the demotion of Pluto from a planet to a dwarf planet adds, "All those people who are mad that Pluto is no longer a planet can be thrilled to know that there is a real planet out there still to be found. Now we can go and find this planet and make the Solar System have nine planets once again."

World's first virtual reality rollercoaster

In a groundbreaking move that could revolutionise the world of theme parks, the UK's Alton Towers Resort announces today it is launching a rollercoaster entirely dedicated to virtual reality.

 

alton towers virtual reality rollercoaster technology

 

Set to open in April, Galactica is the world's first rollercoaster entirely customised for the full virtual reality experience, transforming riders into astronauts and plunging them into outer space with a G force of 3.5, which is more powerful than the 3G of a real rocket launch.

The exhilarating new ride will combine the physical exertion and adrenaline rush of Alton Towers' iconic flying rollercoaster, with the breathtaking sensation of travelling through space. Cutting edge technology launches riders into a different world, complete with virtual space suits, stunning visuals and an exciting adventure. The visuals have been perfectly synchronised to the thrilling twists, turns and loops of the rollercoaster to recreate the sensation of hurtling through space. Visitors will ride in a prone position along the 840-metre long (2,760 ft) track, to recreate the feeling of flying.

Galactica's epic space theme is set to be hugely popular following Tim Peake's maiden voyage into space in December 2015. Stunning, high-quality visuals deliver an immersive experience that its designers claim is breathtakingly realistic. Each rider wears a modified Samsung Gear VR headset. Through this, an on-board artificial intelligence guides them from the launch pad up into space – flying and looping beyond the stars, banking through wormholes and speeding across distant galaxies, revealing the wonders of the cosmos in stunning clarity.

Commenting on the new attraction, Marketing Director Gill Riley says: "Galactica uses groundbreaking technology to give riders a breathtaking and completely unique rollercoaster experience. Tim Peake captured the imagination of millions of Brits last year when he set off on his mission to the International Space Station – and now our visitors can become astronauts too.

"There is nowhere else in the world that people can experience the feeling of a flying rollercoaster combined with soaring through the universe. For two minutes, our guests will be transported into space and we believe Galactica showcases the future for theme parks around the world – it's a complete game changer!"

In recent weeks, a team of engineers at NASA's Goddard Space Flight Centre have been working tirelessly to install the JWST's mirror segments onto the telescope structure. The first piece was fitted on 25th November, and this week it was announced that the ninth piece is now in place.

"The years of planning and practicing are really paying dividends and the progress is really rewarding for everyone to see," said Lee Feinberg, NASA's Optical Telescope Element Manager.

In these NASA images, a robotic arm can be seen lifting and lowering the hexagonal-shaped segments that each measure 4.2 feet (1.3 metres) across and weigh 88 pounds (40 kilograms). After being pieced together, these 18 primary mirror segments will combine to function as a single large 21.3-foot (6.5-metre) mirror. The full installation is expected to be complete in early 2016, with deployment scheduled for 2018.

The James Webb Space Telescope is the scientific successor to NASA's Hubble Space Telescope that was launched in 1990. It will be the most powerful space telescope ever built – using near-infrared wavelengths to see the very first generation of stars that ignited after the Big Bang. The JWST is an international project led by NASA with its partners, ESA (the European Space Agency) and the Canadian Space Agency.

InSight mission to Mars postponed until at least 2018

NASA has postponed its launch of the InSight Mars mission in March 2016, due to an air leak in one of the primary scientific instruments. It is currently unclear if the mission will be cancelled entirely or delayed until 2018.

After thorough examination, NASA managers have decided to suspend the planned March 2016 launch of the Interior Exploration using Seismic Investigations Geodesy and Heat Transport (InSight) mission. This follows unsuccessful attempts to repair a leak in part of the prime instrument in the science payload.

"Learning about the interior structure of Mars has been a high priority objective for planetary scientists since the Viking era," said John Grunsfeld, Associate Administrator for the Science Mission Directorate at NASA's HQ in Washington, D.C. "We push the boundaries of space technology with our missions to enable science, but space exploration is unforgiving, and the bottom line is that we're not ready to launch in the 2016 window."

The instrument involved is the Seismic Experiment for Interior Structure (SEIS), a seismometer provided by France's Centre National d'Études Spatiales (CNES). Designed to measure ground movements as small as the diameter of a single atom, it could detect signals from marsquakes, meteorite impacts, local events like dustdevils or landslides, and even the tiny tidal deformation of Mars induced by its moon Phobos. The SEIS requires a vacuum seal around its three main sensors to withstand the harsh conditions of the Martian environment.

 

mars seis insight nasa

 

"InSight's investigation of the Red Planet's interior is designed to increase understanding of how all rocky planets, including Earth, formed and evolved," explains Bruce Banerdt, InSight Principal Investigator at NASA's Jet Propulsion Laboratory in California. "Mars retains evidence about the rocky planets' early development that has been erased on Earth by internal churning Mars lacks. Gaining information about the core, mantle and crust of Mars is a high priority for planetary science, and InSight was built to accomplish this."

A leak earlier this year that had previously prevented the seismometer from retaining vacuum conditions was repaired, and the mission team was hopeful the most recent fix would be successful. However, during testing last week in extreme cold temperature (-49°F/-45°C) the instrument again failed to hold a vacuum. NASA officials have now determined that there is insufficient time to resolve another leak, and complete the work and thorough testing required to ensure a successful mission.

"It's the first time ever that such a sensitive instrument has been built," said Marc Pircher, CNES Director. "We were very close to succeeding – but an anomaly has occurred, which requires further investigation. Our teams will find a solution to fix it, but it won't be solved in time for a launch in 2016."

 

mars insight future timeline

 

The relative positions of Earth and Mars mean the best launch opportunities occur for only a few weeks every 26 months. The current launch window for InSight runs from 4th–30th March 2016.

"When you know you’re going to miss the window, it’s essentially game over, at least for this opportunity," said Grunsfeld. "This is a case where the alignment of the planets matters, and to get from Earth to Mars in the most efficient manner, they’re aligned about every 26 months. So we’re looking at some time in the May 2018 timeframe for the next opportunity."

The mission could even be cancelled altogether: "That is a question that's on the table," according to Grunsfeld. NASA has already spent $525 million on research and development of the spacecraft; a launch delay from 2016 to 2018 automatically triggers a review on its future. NASA is unsure how much the delay and repairs will cost, or whether it will exceed the mission's budget cap. "A decision on a path forward will be made in the coming months," Grunsfeld says.

"The JPL and CNES teams, and their partners, have made a heroic effort to prepare the InSight instrument, but have run out of time given the celestial mechanics of a launch to Mars," said JPL Director Charles Elachi. "It is more important to do it right than take an unacceptable risk."

"In 2008, we made a difficult, but correct decision to postpone the launch of the Mars Science Laboratory mission for two years to better ensure mission success," said Jim Green, director of NASA's Planetary Science Division in Washington. "The successes of that mission's rover, Curiosity, have vastly outweighed any disappointment about that delay."

Since there is still a chance it will go ahead, we have moved the InSight mission from 2016 to 2018 on our timeline.

SpaceX rocket achieves historic vertical landing

Following previous failed attempts, U.S. company SpaceX headed by Elon Musk has achieved a historic milestone in space flight by landing an unmanned Falcon 9 rocket vertically. This achievement paves the way to a new generation of reusable rockets – greatly reducing the cost of access to space.

The rocket was launched from Cape Canaveral in Florida, delivering 11 communications satellites into low Earth orbit for the Orbcomm-2 mission before returning 10 minutes later about 9.65km (6 miles) south of its launch pad, where it landed in an upright position at 8:39 pm EST.

The U.S. government has passed historic legislation for asteroid mining

The U.S. government has passed historic legislation for asteroid mining, which allows citizens to own, transport and sell "any asteroid resource or space resource" obtained during commercial operations in space.

The U.S. Congress has just passed historic legislation (H.R. 2262), recognising the right of U.S. citizens to own space resources they obtain as property and encouraging the commercial exploration and recovery of materials from asteroids, free from harmful interference.

This legislation creates a pro-growth environment for the development of the commercial space industry by encouraging private sector investment and ensuring a more stable and predictable regulatory regime. The law is important for the industry and will be integral to supporting U.S. interests as the commercial space sector continues to expand.

“We are proud to have the support of Congress,” said Chris Lewicki, President and Chief Engineer of Planetary Resources. “Throughout history, governments have spurred growth in new frontiers by instituting sensible legislation. Long ago, the Homestead Act of 1862 advocated for the search for gold and timber, and today, H.R. 2262 fuels a new economy that will open many avenues for the continual growth and prosperity of humanity. This off-planet economy will forever change our lives for the better here on Earth.”

Eric Anderson, Co-Founder and Co-Chairman of Planetary Resources, said: “Many years from now, we will view this pivotal moment in time as a major step toward humanity becoming a multi-planetary species. This legislation establishes the same supportive framework that created the great economies of history, and it will foster the sustained development of space.”

Daniel Faber, the CEO of rival firm Deep Space Industries (DSI), also commented: “This is a very thoughtfully worded piece of legislation that is sensitive to the existing Outer Space Treaty, and yet moves the ball far forward in terms of giving companies like DSI the legal certainty we need to invest in capitally intensive missions and equipment.”

 

asteroid mining technology future timeline

 

Previously confined to the realm of science fiction, asteroid mining has begun to seem like a serious possibility in recent years. Thanks to the entrepreneurial efforts of Planetary Resources, DSI and other firms, new technologies are being developed that could soon unlock the vast untapped metal and mineral wealth buried throughout the Solar System. In July of this year, Planetary Resources successfully deployed its Arkyd 3 Reflight (A3R) spacecraft from the Kibo airlock of the International Space Station (ISS). This test featured a number of core technologies that will be incorporated into future spacecraft. A larger and more advanced demonstration craft, the Arkyd-6 (A6), is now planned.

Eventually, these prototypes will be followed by probes capable of rendezvousing with Near-Earth objects (NEOs) identified as being rich in resources. They will deploy machines able to drill into rocks and extract their contents for in-situ utilisation (e.g. construction materials and rocket propellant) or return to Earth. Planetary Resources is confident it will begin commercial operations in the 2020s.

With sufficient commitment and long-term investment, asteroid mining could solve the looming resource shortage here on Earth. A single 500-metre asteroid could contain more platinum group metals than have ever been mined in human history. Establishing a solid legal foundation for the development of space resources is a necessary first step in opening the frontier. The new legal framework passed this week is essential for serious investment to occur in what may become one of the biggest industries of all time.

BAE Systems and Reaction Engines to develop a groundbreaking new aerospace engine

BAE Systems and Reaction Engines Ltd. today announced a strategic investment by BAE Systems and a working collaboration to accelerate the development of SABRE – a new class of aerospace engine that combines both jet and rocket technologies and could potentially revolutionise hypersonic flight and the economics of space access.

 

reaction engines skylon space plane

 

Under the terms of the agreement, BAE Systems will invest £20.6 million in Reaction Engines to acquire 20 per cent of its share capital and also enter into a working partner relationship. The working partnership will draw on BAE Systems' extensive aerospace technology development and project management expertise and will provide Reaction Engines with access to critical industrial, technical and capital resources to progress towards the demonstration of a ground-based engine – a key milestone in the development of the technology. Under the agreement, BAE Systems will enter into a preferred supplier relationship with Reaction Engines in certain agreed areas and will have representation on the board of Reaction Engines.

Reaction Engines is a privately held company based in the United Kingdom developing the technologies needed for an advanced combined cycle air-breathing rocket engine called SABRE (Synergetic Air-Breathing Rocket Engine). This new class of aerospace engine is designed to enable aircraft to operate from standstill on the runway to speeds of over five times the speed of sound in the atmosphere. SABRE can then "transition" to a rocket mode of operation, allowing spaceflight at speeds up to orbital velocity, equivalent to 25 times the speed of sound. Reaction Engines' technology has undergone extensive independent technical assessments which have confirmed its viability and potential applications.

A key element of the SABRE engine is a breakthrough in aerospace engine technology of ultra-lightweight heat exchangers that allow the cooling of very hot airstreams from over 1,000 °C to minus 150 °C in less than 1/100th of a second, whilst preventing the formation of ice at sub-zero temperatures.

The UK Government is expected to confirm grant funding of £60 million for Reaction Engines to further SABRE's development towards a ground-based test engine and to investigate its applications for space access vehicles. Together with BAE Systems' investment, this injection of capital will support the transition from a research phase into development and testing of the engine. The ground-based test engine is expected to be ready by 2020 and the first unmanned test flights could happen by 2025.

 

reaction engines skylon space plane

 

Mark Thomas, Managing Director of Reaction Engines: "Today's announcement represents an important landmark in the transition of Reaction Engines – from a company that has been focused on the research and testing of enabling technologies for the SABRE engine, to one that is now focused on the development and testing of the world's first SABRE engine. BAE Systems brings industry-leading capabilities in programme delivery and wider engineering systems integration that will accelerate the development of SABRE as a new engine class and its vehicle applications. This partnership builds on the outstanding technical breakthroughs that Reaction Engines has made and the positive assessments received on the potential of the technology from experts at the European Space Agency and the United States' Air Force Research Laboratory."

Nigel Whitehead, Group Managing Director, Programmes & Support, BAE Systems: "Reaction Engines is a highly innovative UK company and our collaboration gives BAE Systems a strategic interest in a breakthrough air and space technology with significant future potential. Our partnership with Reaction Engines is part of our sustained commitment to investing in and developing prospective emerging technologies. BAE Systems' considerable engineering and development expertise will help support the delivery of the first demonstrator for the SABRE engine."

Jo Johnson MP, UK Minister for Universities and Science said: "This investment by BAE Systems reflects the strength of British engineering and technology and our ambitions as a leading space nation. I am sure that this partnership will strengthen both organisations – helping to create more jobs in the UK's growing space sector and ultimately to make the SABRE engine a reality."
