Our Emissaries Across the Solar System
Earth has launched thousands of spacecraft, but precious few have made it beyond Earth orbit. Currently, 13 spacecraft representing 11 missions are actively gathering science data from planetary destinations. These are MESSENGER at Mercury; Venus Express at Venus; Lunar Reconnaissance Orbiter, GRAIL, and ARTEMIS at the Moon; Odyssey, Mars Express, Mars Reconnaissance Orbiter, and Opportunity at Mars; Dawn at Vesta; and Cassini at Saturn.
Meanwhile, Curiosity is on its way to Mars, Rosetta to a comet, New Horizons to Pluto, and Akatsuki attempting to retry a Venus arrival, while Chang'E 2 and both Voyagers have turned from planetary to heliophysics missions, and IKAROS' condition is unknown. All of these missions follow in the footsteps of dozens of predecessors, the few human-built artifacts ever to have departed Earth.
Recent Mission Status Updates
After more than two months of very slow driving due to concern about the wheels and time spent choosing whether to enter "Dingo Gap" or not, Curiosity has safely crossed the dune and resumed longer drives, achieving 75 meters and crossing the 5-kilometer mark on sol 540.
A terse Xinhua news report posted today says there may be some sign of life from Yutu, now that the Sun has risen on the third lunar day since Chang'e 3 landed. It is frustratingly non-specific. UPDATE: Amateur radio operators have detected a radio signal from the rover.
