One of my all-time favorite space images is this little gem from the Clementine mission to the Moon, launched in January of 1994. It features a view from beyond the far side of the Moon, illuminated by reflected light off the Earth off frame to the left, blocking the disc of the Sun with the solar corona and Venus shining brightly in the background. Absolutely stunning!
The image above was taken by one of the two Star Tracker navigation cameras aboard the Clementine spacecraft. Clementine also had a suite of much more sophisticated cameras aboard to map the surface of the moon in a wide range of wavelengths; for example, the image below shows a map of the lunar farside made of a mosaic of tens of thousands of Clementine UVIS images:
Clementine also captured this amazing image of an “Earthrise” over the Moon’s north pole:
Clementine was a joint NASA and Ballistic Missile Defense Organization mission to map the lunar surface and then the 3-mile-wide near-Earth asteroid Geographos. After leaving lunar orbit, a malfunction prevented Clementine from completing the second portion of its mission. Even though it never succeeded in reaching the asteroid the vast amounts of multi-spectral digital data from the pole-to-pole lunar mapping portion prompted President Bill Clinton to dub Clementine a major national achievement in aeronautics in space. The Clementine mission was inducted into the Space Hall of Fame in 1996.
