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 t NASA's James Webb telescope completes mirror alignment, heads for orbit

Most galaxies, including our own, grow by accumulating new material and turning them into stars - that much is known. What has been unknown is where that new material comes from and how it flows into galaxies to create stars.
In a recently published study, Arizona State University astronomer Sanchayeeta Borthakur has identified the faint fuel reservoirs that surround galaxies, and how this Capturing all that glitters in galaxies with NASA's Webb

Spirals are some of the most captivating shapes in the universe. They appear in intricate seashells, carefully constructed spider webs, and even in the curls of ocean waves. Spirals on cosmic scales - as seen in galaxies - are even more arresting, not only for their beauty, but also for the overwhelming amount of information they contain.

Who would ever have thought that technology used on China's largest carrier rocket would be used to improve the safety of skiers?
Chinese scientists have developed a strong ski helmet with space technology originally used on the Long March-5 rocket, the country's heaviest launch vehicle and the carrier of Mars probe Tianwen-1.

New automatic control technique uses spacecraft solar panels to reach desired orbit at Mars
Wednesday, 19 January 2022 13:49 Write a comment
A satellite on a science mission to Mars aims for a low-altitude orbit, but the lower the orbit, the more propellant is required to enter orbit when arriving from Earth. To save propellant, a technique called aerobraking uses a small propulsive maneuver for orbit insertion to enter a large orbit; the satellite then makes many passes through the upper atmosphere, using drag on the solar panels to reduce the size of the orbit a little bit each pass until the orbit is the desired size for science operations.

It took a crop of potatoes to keep Matt Damon alive on the red planet in The Martian. And in future, real life astronauts on the Moon and Mars will have to be gardeners, farmers and expert recyclers as well as explorers. Do you have promising ideas that might help them to get by in space on next to no resources?
