The Upper Atmosphere Research Satellite that has been befuddling NASA scientists with its unpredictable reentry path has finally fallen back to Earth. We... just don't know where yet exactly. But you're safe to look up now.
This weekend NASA published an awesome time-lapse flyby of planet Earth taken from the International Space Station. Awesome, but jerky—until now. Someone interpolated the original frames to achieve this smooth as silk motion film. It'll leave you stupefied.
The HEXAGON satellite spied on America's Cold War foes for over a decade, taking extremely detailed (film!) photographs from space. It was 60 feet long—bigger than a bus. And the public never, ever saw it. We did.
