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.
Recent Mission Status Updates
Juno may be staying in its 53.5-day orbit for quite a while. Here's a list of the future dates of the next 20 close approaches to Jupiter if the mission stays in that orbit, as well as the latest, near-final version of JunoCam's "Marble Movie."
International Space Station (ISS) project partners are inching ever closer toward an agreement to begin the development of a new human outpost in the vicinity of the Moon. If successful, the cis-lunar space station (a space station in the vicinity of the Moon) will be the largest international space project to date, influencing the direction of human space flight for decades to come.

Our Advocacy Program provides each Society member a voice in the process.
Funding is critical. The more we have, the more effective we can be, translating into more missions, more science, and more exploration.
