Solar eclipse as seen from the Moon shot by NASA
During the total solar eclipse on August 21, NASA's Lunar Reconnaissance Orbiter around the Moon captured the Moon's shadow over a large region of the US. The orbiter captured the shadow racing at 2,400 kmph, producing the US' first coast-to-coast solar eclipse in 99 years. The $500-million spacecraft launched in 2009 is currently collecting essential data for future lunar missions.
