New report argues for ownership of the Moon

16th February 2022

The Adam Smith Institute (ASI), a neoliberal think tank based in London, UK, has published a new report on property rights in space. It suggests dividing the Moon into regions and privatising it, which the institute believes could help end global poverty.

Space Invaders: Property Rights on the Moon, by economic consultant Rebecca Lowe, argues that creating a clear system of property rights in space could empower all of humanity with a greater stake in space exploration, as well as accelerating scientific discovery.

The Outer Space Treaty of 1967 – of which 111 countries are party to, including all major spacefaring powers – states that space is the "province of all mankind" and shall be freely explored and used by all nations. It precludes any country from claiming sovereignty over outer space or any celestial body, regardless of what national flags are planted on its surface.

However, the ASI believes this way of thinking has become outdated and is holding back humanity's potential. Recent advances in space travel and commercialisation from the likes of SpaceX, Blue Origin, and other companies have opened up the possibility of Moon settlement in the relatively near future and the time has therefore come for a fresh approach to space resource utilisation, the institute says.

Lowe's paper sets out a framework for individuals to gain morally-justified property rights in space, with a particular focus on plots of Moon land. Under the proposed system, individuals would compete against each other for plots of land on the Moon (that have most likely been initially acquired by, or assigned to, particular nations). This competition would involve paying 'rent' for such plots – the area and cost of which would be determined by supply and demand. A rebate could be given for improving the condition of land or providing for urgent human needs. Governance would currently depend on international agreement.

Chinese Rover Finds Translucent Glass Globules on the Moon
by Nancy Atkinson
February 24, 2022

https://www.universetoday.com/154669/ch ... ore-154669

Introduction:
(Universe Today) Scientists say China’s Yutu-2 rover, part of the Chang’E-4 mission, has found several small glass globules on the Moon’s far side. While tiny glass beads have been found previously in lunar samples brought back by the Apollo astronauts, the ones found by Yutu-2 are much bigger and translucent.

The discovery was made by Dr. Zhiyong Xiao, one of the lead scientific team members of the Chang’E-4 mission. The beads were found by looking at panoramic images taken by the rover. Since the rover doesn’t have sampling capabilities and is not a sample return mission like it’s older sibling, the Chang-E-5 mission, there is no compositional data on the glass beads, only observational evidence.

In the paper published in the Science Bulletin, Xiao said taking into account the location where the glass was found – in the South Pole Atkien basin at the lunar farside – and the local context of what is known about that region, they believe the beads are...most likely the result of large impacts to the Moon.

The paper details the discovery of several translucent spherical and dumbbell-shaped glassy globules that range in size, but are as large as 4 centimeters (1.5 inches). They were found on the surface of the Moon, and are transparent to translucent, with some exhibiting a light brownish color.

Scientists help recover gases from moon rock time capsule
https://phys.org/news/2022-03-scientist ... psule.html
by Talia Ogliore, Washington University in St. Louis
Scientists from Washington University in St. Louis are helping to recover gases from a container of lunar soil that astronauts collected and sealed under vacuum on the surface of the moon in 1972. The effort is part of NASA's Apollo Next Generation Sample Analysis (ANGSA) initiative.

Apollo 17 astronauts Harrison Schmitt and Eugene Cernan collected the sample from the site of an ancient landslide in the moon's Taurus-Littrow Valley. The astronauts used a coring device to dig out a column of lunar regolith—a rough mixture of dust, soil and broken rock from the surface of the moon—and sealed it in a container. Back on Earth, NASA carefully placed the container in the lunar vault at NASA's Johnson Space Center, where it has remained in pristine condition, virtually untouched until now.

"For the last 50 years, the lunar core was enclosed in a core sample vacuum container, which was then enclosed in an outer vacuum container," said Alex Meshik, a research professor of physics in Arts & Sciences and faculty fellow of the university's McDonnell Center for the Space Sciences. "They were nested together, almost like Russian dolls."

The containers were placed in two sealed Teflon bags and stored in a nitrogen glove box in a vault.

Cracking the containers open, as Meshik and collaborators did last month, was tricky. The scientists needed to be able to identify the original chemical signature of every bit of gas that could be in the containers. That includes lunar gas that might have been captured at the time the lunar regolith was collected on the surface of the moon, as well as any other gases that could have seeped from the rocks during the subsequent decades in storage.

China’s Lunar Lander Finds Water Under its Feet
by Nancy Atkinson
June 15, 2022

Introduction:
(Universe Today) Earlier this year, scientists from China’s Chang’E-5 lunar lander revealed they had found evidence of water in the form of hydroxyl from in-situ measurements taken while lander was on the Moon. Now, they have confirmed the finding with laboratory analysis of the lunar samples from Chang’E-5 that were returned to Earth. The amount of water detected varied across the randomly chosen samples taken from around the base of the lander, from 0 to 180 parts per million (ppm), mean value of 28.5?ppm, which is on the weak end of lunar hydration.

“For the first time in the world, the results of laboratory analysis of lunar return samples and spectral data from in-situ lunar surface surveys were used jointly to examine the presence, form and amount of ‘water’ in lunar samples,” said co-author Li Chunlai from the National Astronomical Observatories of the Chinese Academy of Sciences (NAOC), in a press release. “The results accurately answer the question of the distribution characteristics and source of water in the Chang’E-5 landing zone and provide a ground truth for the interpretation and estimation of water signals in remote sensing survey data.”

The researchers, who published a paper in Nature Communications, said the laboratory analysis of the also provide critical clues to the possible sources of these hydroxyl. Hydroxyl is a close chemical cousin of water (H2O). Hydroxyl is HO, with one atom of oxygen and one of hydrogen.
The article goes on to explain that there seems to be two basic sources of the hydroxyl. One, from “solar wind implantation (that) can bring water to the lunar surface. Charged particles from the Sun drive hydrogen atoms to the lunar surface where they later bonded with oxygen to form water and hydroxyl.” The other is so-called indigenous hydroxyl which is embedded in the rock of the Moon’s surface.

NASA delays ice-hunting VIPER moon rover launch to 2024, a one-year slip
published about 6 hours ago

Image

NASA's new VIPER lunar rover must wait at least an extra year to search for ice on the surface of the moon.

The VIPER moon rover will now launch no earlier than 2024 following a NASA request for more ground testing of the Griffin lunar lander. Both Griffin and VIPER are made by the company Astrobotic.

The ice-hunting VIPER rover, the name is short for Volatiles Investigating Polar Exploration Rover, was supposed to touch down in November 2023 in the lunar south polar region to assess how much water might be available for human missions. NASA, however, asked for more time to assess Griffin's readiness for its debut mission, pushing the landing to November 2024.

"The additional tests aim to reduce the overall risk to VIPER's delivery to the moon," NASA said of the decision in a release(opens in new tab) Monday (July 18), but provided no other details. Astrobotic made no comment on social media or in a news release.

The Commercial Lunar Payload Services (CLPS) contract for Astrobotic will be allocated an additional $67.8 million to fulfill the extra work, bringing the total cost to $320.4 million, NASA stated.

Johns Hopkins Applied Physics Laboratory Assembles First Global Map of Lunar Hydrogen
July 20, 2022

Introduction:
(EurekAlert) Using data collected over two decades ago, scientists from the Johns Hopkins Applied Physics Laboratory (APL) in Laurel, Maryland, have compiled the first complete map of hydrogen abundances on the Moon’s surface. The map identifies two types of lunar materials containing enhanced hydrogen and corroborates previous ideas about lunar hydrogen and water, including findings that water likely played a role in the Moon’s original magma-ocean formation and solidification.

APL’s David Lawrence, Patrick Peplowski and Jack Wilson, along with Rick Elphic from NASA Ames Research Center, used orbital neutron data from the Lunar Prospector mission to build their map. The probe, which was deployed by NASA in 1998, orbited the Moon for a year and a half and sent back the first direct evidence of enhanced hydrogen at the lunar poles, before impacting the lunar surface.

When a star explodes, it releases cosmic rays, or high-energy protons and neutrons that move through space at nearly the speed of light. When those cosmic rays come into contact with the surface of a planet, or a moon, they break apart atoms located on those bodies, sending protons and neutrons flying. Scientists are able to identify an element and determine where and how much of it exists by studying the motion of those protons and neutrons.

Korea’s Lunar Orbiter Heads for the Moon
by David Dickinson
August 5, 2022

Extract::
(Sky & Telescope) A SpaceX Falcon 9 rocket lit up the skies over Cape Canaveral in Florida yesterday evening, taking with it South Korea’s first Moon mission: the Korea Pathfinder Lunar Orbiter, now officially called Danuri. The $180 million mission is a pathfinder for an eventual mission with an orbiter, lander, and rover.

WHAT DANURI WILL DELIVER

The mission's name, Danuri, is a portmanteau of the Korean words dal and nurida, collectively meaning “enjoy the Moon.” The mission will scout the lunar surface for minerals and elements, including aluminum, helium-3, and surface water ice.

To accomplish this, the solar-powered spacecraft carries six instruments, one from NASA and five from the Korea Aerospace Research Institute (KARI):
  • The Wide-Angle Polarimetric Camera (PolCam) will image and analyze the lunar regolith in polarized light. Though Earth-observing satellites have long used this technique, this is the first time a polarized-light imager has flown to the Moon. Bill Farrand (Space Science Institute) says that he will use PolCam to explore the nature of pyroclastic deposits, which formed early in the Moon's history during explosive volcanic activity.
  • The KPLO Magnetometer contains three sensors that will characterize the magnetic field lines frozen into lunar rocks.
  • The Lunar Terrain Imager will take sharp images of future landing sites, resolving features down to just 16.5 feet (5 meters) across.
  • The Delay-Tolerant Networking experiment will test a sort of “interplanetary internet” by addressing the technical issues that arise in a communications network that lacks continuous connectivity.
  • The Gamma Ray Spectrometer is a gamma-ray spectrometer that works in the 10 kilo-electron volt (keV) to 10 mega-electron volt (MeV) range to probe the surface of the Moon in search of key chemicals and elementsKPLO in the clean room on Earth.

NASA's Artemis 1 Moon Mission Will Carry Two Water-seeking Cubesats
by Stefanie Waldek
August 15, 2022

Introduction:
(Space.com) When Artemis 1 launches, hopefully on Aug. 29, its primary mission is simple: test the brand new Space Launch System (SLS) rocket, the Orion spacecraft, and the ground systems at Kennedy Space Center in Florida. NASA hopes that this combination of technology will see humans return to the moon in a few years.

But that means Artemis 1 will be headed for the moon, an opportunity not to be missed, so it will be taking with it 10 secondary payloads. Two of those are cubesats designed to search the moon for water: Lunar IceCube and Lunar Polar Hydrogen Mapper (LunaH-Map). As humans return to the moon — and travel beyond — the discovery of water is crucial for long-duration missions, since would-be explorers hope to harvest breathable air and rocket fuel from the ice.

Lunar IceCube is being developed by Morehead State University in Kentucky. The 31-pound (14 kilograms) cubesat will carry a NASA instrument called the Broadband Infrared Compact High-Resolution Exploration Spectrometer (BIRCHES), which will map water on the lunar surface as well as in the exosphere, the thin layer of gas surrounding the moon like a very weak imitation of Earth's atmosphere.

"Lunar IceCube will help pave the way for human missions through significantly less expensive robotic missions and by addressing water dynamics on the moon," Mark Lupisella, a NASA exploration research and development manager, said in a statement. "This is not only important for science, but it could also be important for reducing the cost of human missions over the long-term."

The mission will also test a new ion propulsion thruster, which "operates electrically using small amounts of propellant to give a small push and drive the spacecraft along its path, similar to that of butterfly wings," according to NASA.
