We have accomplished a lot in the past 30-plus years. Don't worry, we haven't forgotten about any of the exciting space exploration projects made possible by the generous support of you -- our members and supporters. It is just taking us awhile to migrate all of that great information from the old website to the new one.
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.
The Bush Administration cancelled it twice, NASA claimed its budget couldn't cover it and Congress earmarked funds to be cut in mid-development; yet the trail-blazing New Horizons Pluto-Kuiper Belt mission has survived. This is no doubt due in part to the relentless public campaigning led by The Planetary Society.
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 "nanorover," 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.
Visions of Mars is a message from our world to future human inhabitants of Mars, which arrived on the Red Planet on board the spacecraft Phoenix. Along with personal messages from leading space visionaries of our time, Visions of Mars includes a priceless collection of Mars literature, and art, and a list of hundreds of thousands of names of space enthusiasts from around the world.
