Space Missions

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.
