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.
Our space missions pages are your portal to news and facts about our ongoing exploration of the solar system.
Recent Mission Status Updates
Only about three weeks remain until the flyby -- it's getting really close! I almost don't want the anticipation to end. New Horizons is now getting color images and is seeing features on Charon. Deep searches have yielded no new moons.
I woke up early Sunday morning to the dramatic news: Philae is back! With a few days to consider the telemetry, the Philae team is now talking about the science they hope to do. With comet Churyumov-Gerasimenko approaching perihelion in August, it's going to be an exciting ride.
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.
