What We Do
The Planetary Society creates ways for the public to have active roles in space exploration. Engaging citizen scientists through our projects and citizen science activities, we aim to foster a scientifically literate populace, one in which every citizen knows and appreciates other worlds as well as this one. We develop innovative technologies, like the first solar sail spacecraft, we fund astronomers hunting for hazardous asteroids and planets orbiting other stars, we support radio and optical searches for extraterrestrial life, and we influence decision makers, ensuring the future of space exploration.
NASA and other countries have studied large rovers designed to carry humans, medium-sized robotic rovers like those used now on Mars, and even a low-gravity "nano?rover," but there is a largely unstudied niche of microrovers, which we loosely define as rovers with masses of one to a few kilograms. Even less studied is how they might work with humans on the Moon, Mars, or other bodies.
At the core of our explorations is the quest to know if life exists beyond Earth. The Planetary Society is a leader in the search for life on other worlds, whether intelligent or microbial. Our active projects: SETI Optical Telescope - Looking for laser signals beamed across the vastness of space. SETI Radio Searches - Huge radio dishes sift through nature's random noise for beacons from other civilizations.
The Planetary Society is an education outreach partner on Mars Climate Sounder and is proud to be a part of this next phase of Mars exploration. Mars Climate Sounder, one of Mars Reconnaissance Orbiter's six science instruments, is performing a detailed, systematic study of Mars' weather and climate.
Something strange was happening in the outer reaches of our solar system. The Pioneer 10 and 11 spacecraft were not where they were supposed to be. The mystery of the Pioneer Anomaly has been solved The recovery of Doppler and telemetry data and the entire effort in thermal analysis would not have happened without the Planetary Society.
They are Watching the Skies for You!
Our researchers, worldwide, do absolutely critical work.
Asteroid 2012DA14 was a close one.
It missed us. But there are more out there.
