If you want to know why Cassini might be terminated early, or why NASA pulled out of its joint Mars mission with Europe, or why the new ASRG power source was put on indefinite hold, this chart has your answer.

ASRGs could have stretched NASA's limited supply of plutonium to potentially enable missions to the perpetually-shadowed polar craters on our moon, to flyby Uranus, or to float for months on a Titan lake.

Decisions about both the 2014 and 2015 budgets are happening soon.

Bill Nye

Bill Nye writes President Obama arguing that the President should embrace a bold future of planetary exploration.

We present an update and a video about the successful design, construction, and testing in a vacuum chamber by Honeybee Robotics of a prototype PlanetVac system, a new planetary surface sampling technique, sponsored by The Planetary Society. PlanetVac is a reliable system that effectively vacuums up planetary surface materials.

I called one of my Senators earlier today. Before that I called my representative. It was pretty easy.

Bright and early this morning, we NASA Social folks met at the Kennedy Space Center Visitors Complex for a tour of the space shuttle Atlantis. This is the first shuttle I've seen in person, and it was a stunning sight to see.

The Advanced Stirling Radioisotope Program (ASRG) was just cancelled by NASA. This was to be the saving grace for Plutonium-238 availability, as it was a much more efficient way to generate electricity than classic RTG systems.

An update from University of Strathclyde researchers about the Planetary Society sponsored laboratory Laser Bees asteroid deflection project including a new laser and other lab equipment, and the start of new related projects.

Casey Dreier

We report on the current state of Plutonium-238 production in the United States, a crucial fuel source for planetary exploration spacecraft.

The Planetary Society’s work beyond the United States is still not nearly as extensive as it is in the Society’s home country. But we are making some huge steps towards changing that, starting with Canada – America’s neighbor, NASA’s partner, and the home of almost eighteen hundred Planetary Society members.
