Apollo rock samples capture key moments in the Moon’s early history, study find
Volcanic rock samples collected during NASA’s Apollo missions bear the isotopic signature of key events in the early evolution of the Moon, a new analysis found. Those events include the formation of the Moon’s iron core, as well as the crystallization of the lunar magma ocean—the sea of molten rock thought to have covered the Moon for around 100 million years…
Linux Is Now on Mars, Thanks to NASA’s Perseverance Rover
“When NASA’s Perseverance rover landed on Mars this week, it also brought the Linux operating system to the Red Planet,” reports PC Magazine: The tidbit was mentioned in an interview NASA software engineer Tim Canham gave to IEEE Spectrum. The helicopter-like drone on board the Perseverance rover uses a Linux-powered software framework the space agency open-sourced a few years ago. “This…

Dark streaks on Mars may be caused by salts and melting ice
Researchers at the SETI Institute say that unusual dark streaks on sun-facing slopes on Mars, debated about for years, may be small landslides caused by a combination of salts and melting ice just below the surface.
