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 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 out into the Kuiper Belt after its 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.
