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
There was celebration in the Mars mission control room in Bangalore on Monday following the success of the crucial four-second test firing of the Mars Orbiter Mission’s (MOM) 440-Newton liquid apogee motor. MOM will now go ahead with the nominal plan for the Mars orbit insertion on September 24 at 07:30 IST (02:00 UT / September 23 19:00 PDT).
Today's the day that MAVEN enters orbit at Mars, bringing the number of Mars orbiters up to four. So far everything looks good. The orbit insertion burn should begin tonight at 18:50 PDT / 01:50 UTC. I'll be on stage with Mat Kaplan and Rich Zurek at Planetary Radio Live, keeping up to date with the latest news from the spacecraft; here is a timeline in PDT, UTC, CEST, and IST to help you follow along.
Space Mission Timelines
In 2016, The Planetary Society’s LightSail program will take the technology a step further.
