Our Emissaries Across the Solar System
Since 1957, humanity has launched thousands of spacecraft. These robotic emissaries follow in the footsteps of their predecessors—testaments to our long-lived desire to understand our place in the Cosmos.
There are currently spacecraft exploring Mercury, Venus, Mars, and Saturn, as well as a comet and an asteroid. The Voyager spacecraft are hurtling out of our solar system, while New Horizons speeds toward a 2015 encounter with Pluto. Closer to home, we have probes in lunar orbit, a handful of solar physics missions, space telescopes, and a small army of Earth-observing satellites. In Earth orbit, the International Space Station continues to soar around the planet with a continually staffed crew of astronauts and cosmonauts.

Recent Mission Status Updates
After a wait of more than 22 hours with no communication, New Horizons "phoned home" precisely on schedule after its flyby of Pluto. The signal was received at 00:52:37 UT | 20:52:37 ET | 17:52:37 PT. As planned, New Horizons returned no images with the Phone Home downlink. But every bit of telemetry indicated that the flyby executed successfully.
With all the focus on Pluto it's hard to keep up with all the other space missions currently exploring other planets. Here are brief updates on three of them.
Space Mission Timelines
Fifteen years ago, Society members and passionate space advocates like you helped save the Pluto mission. Now we can do the same for missions to Europa and Mars.
