I’m excited to report some big news on The Planetary Society’s LightSail project: actual launch dates on actual launch vehicles!

Europa may get a mission...eventually. We give our first take on the 2015 NASA Budget request. How does Planetary Exploration fare? Which projects were cancelled? Will NASA capture an asteroid? And most importantly, what can you do about it?

Lockheed, the prime contract on the now-defunct Advanced Stirling Radioisotope Generator program, is closing out the project and transferring its hardware to NASA's Glenn Research Center. NASA expects to save about $55 million per year.

Pat yourself on the back. Planetary exploration will be more vibrant in 2014 thanks to you. More than fifty thousand messages were sent to Congress this year, and they listened, adding back a significant amount of money in the 2014 Omnibus spending bill.

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.

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.

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

Society Advocacy and Outreach Coordinator Casey Dreier visits Planetary Radio with the tale of an element that is essential to exploration of deep space.

Plutonium-238 provides electricity to deep space missions, but NASA only has a little bit left. A new article in Wired highlights the disastrous consequences of no plutonium for use in space, something the Planetary Society is currently fighting for in Washington, D.C.

A recent report shows that major programs within the Department of Energy are billions of dollars over budget due to lax oversight, yet the congressional committees responsible for the Department

The Advanced Stirling Radioisotope Generator (ASRG) is no longer an option for powering a potential Europa mission. The ASRG uses Plutonium-238 to generate electricity, but is far more efficient than past RTGs.

A large asteroid is passing reasonably close to Earth in a few hours, and astronomers at the great radio telescopes at Goldstone and Arecibo are zapping it. The latest discovery: QE2, like many asteroids, is a binary.

No mission to Europa, diminished funding for outer planets missions, a small bump to small spacecraft missions, and an increase for asteroid detection are part of the White House's proposal for NASA in 2014.

The President signed the Senate's bill to fund the government for the remainder of 2013, and it includes some positive news for NASA's Planetary Science division, which is facing a 21% cut.

Casey Dreier

We celebrate success as Congress passes a bill that restores funding to NASA's Planetary Science program, allowing for more missions, begins a mission to Europa, and funds Plutonium fuel development.
