Wow! The International Space Station, orbiting Earth at 17,500mph, transits the full moon this evening, as seen from near Paynes Prairie Preserve in Florida.

The window to capture this transit lasted a mere *0.58 seconds.* #SpotTheStation

Samples returned from the lunar surface confirm that lunar regolith is made up of 40–45% percent oxygen by weight, its single most abundant element. But this oxygen is bound up chemically as oxides in the form of minerals or glass, so is unavailable for immediate use.

ESTEC’s oxygen extraction is taking place using a method called molten salt electrolysis, involving placing regolith in a metal basket with molten calcium chloride salt to serve as an electrolyte, heated to 950°C. At this temperature the regolith remains solid.
