These are NASA's GRAIL twin spacecraft's final videos before crashing. Ebb and Flow—as the spacecraft's were affectionately known at the Jet Propulsion Laboratory—turned on their video cameras for one last time three days before impact. The footage is truly beautiful.
Science has long known about the curious gravitational variations of the moon's surface—called mascons—as evidenced by the Doppler shift of radio signals from passing spacecraft. However, researchers are now taking an unprecedented, high-fidelity look at the moon's gravitational field thanks to a pair of washing…
Cue in the Pink Floyd, because NASA's GRAIL (Gravity Recovery and Interior Laboratory) has returned "its first unique view of the far side of the moon used its MoonKAM". Of course, it's not the first video of this side of the Moon, but it's pretty cool anyway.
NASA's new favorite ships for all Middle school students are now ready to start work: GRAIL-B has joined her twin GRAIL-A into a near-polar, elliptical orbit around the Moon.
What you see is a gorgeous photo of the 20-minute rollback of the GRAIL spacecraft before it rocketed on its lunar mission this morning. What I see is some kind of early Federation ship entering warp. Amazing.
At 9:08 this morning, NASA shot two spacecraft into space to visit our beloved moon. As part of the Gravity Recovery and Interior Laboratory mission, the rockets will map the entire lunar surface and interior to see how it formed and evolved.
