Space Topics

In our space topics section, you can see a short history of the spacecraft humans have sent beyond Earth, and get involved in the ever-growing amateur space imaging community.

Space Missions

The Planetary Society follows the world's space exploration missions and produces news and resources you won't find anywhere else.

What is Solar Sailing?

A solar sail, simply put, is a spacecraft propelled by sunlight. Whereas conventional rockets are propelled by the combustion of rocket fuel, a solar sail is pushed forward by light from the Sun.

Amateur Imaging

Most deep-space missions carry cameras to acquire scientific data; but these data can also be used to produce stunning views of distant worlds. And almost all of this data is free and readily available to the public for download.

Pictures of Earth by Planetary Spacecraft

Many solar system explorers take dramatic photos of Earth as they depart, or fly by; some even have photographed Earth from the vantage point of another planet.

A Pale Blue Dot

Look again at that dot. That's here. That's home. That's us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives.

Historical Resources

Our one-of-a-kind resource library contains historical white papers, press kits and other useful material.
