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.
New! International Space Station Dashboard
Our ISS Dashboard shows the station's current position, its current crew roster, live high-definition video from the Columbus module, and more.
Recent Mission Status Updates
Only two days remain until New Horizons' historic encounter with Pluto....two Pluto days, that is. Pluto and Charon rotate together once every 6.4 days, so as New Horizons has approached the pair over the last week, we've been treated to one stately progression of all of their longitudes.
After three weeks of being in a communications blackout on the other side of the Sun during the Earth-Mars solar conjunction, Opportunity phoned home, reporting that she is healthy and ready to continue her mission.
Space Mission Timelines
Our LightSail test mission was successfully completed and our Kickstarter campaign ended June 26th, raising $1.24 million dollars for LightSail's 2016 solar sailing mission! Miss the Kickstarter campaign, but still want to donate? You can!
