Uncovering evidence for an internal ocean in small Saturn moon
https://phys.org/news/2022-01-uncoverin ... small.html
by Southwest Research Institute
A Southwest Research Institute scientist set out to prove that the tiny, innermost moon of Saturn was a frozen inert satellite and instead discovered compelling evidence that Mimas has a liquid internal ocean. In the waning days of NASA's Cassini mission, the spacecraft identified a curious libration, or oscillation, in the moon's rotation, which often points to a geologically active body able to support an internal ocean.

"If Mimas has an ocean, it represents a new class of small, 'stealth' ocean worlds with surfaces that do not betray the ocean's existence," said SwRI's Dr. Alyssa Rhoden, a specialist in the geophysics of icy satellites, particularly those containing oceans, and the evolution of giant planet satellites systems.

One of the most profound discoveries in planetary science over the past 25 years is that worlds with oceans beneath layers of rock and ice are common in our solar system. Such worlds include the icy satellites of the giant planets, such as Europa, Titan and Enceladus, as well as distant planets like Pluto. Worlds like Earth with surface oceans must reside within a narrow range of distances from their stars to maintain the temperatures that support liquid oceans. Interior water ocean worlds (IWOWs), however, are found over a much wider range of distances, greatly expanding the number of habitable worlds likely to exist across the galaxy.

World's first space-based movie and entertainment studio set to launch in 2024 - allowing actors and content creators to film above Earth

Thursday 20 January 2022 18:00, UK

A company behind plans for Tom Cruise to shoot a film in space has revealed it will launch the world's first movie studio in orbit in two years' time.

UK-based Space Entertainment Enterprise (SEE) says the film and sports arena will be in a module which will dock at the International Space Centre (ISS) by late 2024.

Not only will it allow film producers to make movies while orbiting the Earth, but SEE predicts that it will also host sporting events in space and social media influencers who want to make content 250 miles above the planet.

The module - SEE-1 - will form part of the ISS's new commercial arm, Axiom Station, who will also handle construction, and will eventually float free in 2028.

"SEE-1 is an incredible opportunity for humanity to move into a different realm and start an exciting new chapter in space," SEE founders Dmitry and Elena Lesnevsky said.

JWST arrives at L2 point. Hooray, hooray, hooray!
Now the hardest part comes - to set up and focus the telescope. Waiting becomes now more exciting than ever.

To know is essentially the same as not knowing. The only thing that occurs is the rearrangement of atoms in your brain.

SpaceX Funded for On-Earth Rocket Cargo
https://www.nextbigfuture.com/2022/01/174435.html
January 22, 2022 by Brian Wang

SpaceX a $102 million five-year US Air Force contract to demonstrate delivering cargo anywhere on earth (point to point) in an hour. The under one hour delivery is not specified in the contract but using the the SpaceX Starship would enable delivery of up to 220 tons in under one hour. There was a previous rocket cargo contract for SpaceX for about $48 million.

A new nine-engine SpaceX Starship design could transport 220 tons with a range of about 8000 miles. An Airbus A380 can transport 150 tons in a cargo configuration. A C17A can transport about 78 tons up to 2800 miles.

The contract is for the rocket cargo program, a new project led by the Air Force Research Laboratory to investigate the utility of using large commercial rockets for Department of Defense global logistics.

This is the largest contract awarded to date for rocket cargo. U.S. Transportation Command in 2020 signed cooperative research and development agreements with SpaceX and Exploration Architecture Corporation (XArc) to study concepts for rapid transportation through space.

SpaceX Catching Starship and Booster for Ten Times the Launch Rate
January 21, 2022 by Brian Wang

Elon Musk has shared SpaceX simulations of the catching of the SpaceX Starship and booster.

Being able to make the Mechazilla SpaceX catch system will enable SpaceX to a launch, land and relaunch three times a day.

A normal landing, maintenance, craning the booster and starship onto crawlers and moving 1 mph via crawler would mean about one or may two launches a week.
