Mercury is our solar system's smallest planet.
See the most amazing space images of the week, including China's mission to space and Mickey Mouse on Mercury.
NASA's Messenger spacecraft orbiting Mercury spotted three craters that look surprisingly like Mickey Mouse.
NASA's Solar and Heliospheric Observatory (SOHO) snapped imagery of Venus, almost past Mercury, in anticipation of the Venus Transit of the Sun on June 5-6, 2012 (depending where you are in the world).
See photos from Mercury astronaut Scott Carpenter's historic Aurora 7 orbital flight on May 24, 1962.
NASA's Solar and Heliospheric Observatory (SOHO) caught Jupiter, Mercury and the Pleiades Star Cluster converging within its camera's field of view.
Nearly two dozen museums and other locations around the U.S. (plus one in England) boast real spaceships that have carried astronauts on missions to orbit and the moon.
