NASA Just Cancelled its Advanced Spacecraft Power Program
The Advanced Stirling Radioisotope Generator was to use less Plutonium for cheaper missions.
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.
Mars Needs Plutonium! (And so do Saturn, Uranus, Neptune and Points Beyond)
Planetary Radio Talks With Casey Dreier About Restoring Production of an Isotope
Posted by Mat Kaplan on 2013/10/29 10:38 CDT
Society Advocacy and Outreach Coordinator Casey Dreier visits Planetary Radio with the tale of an element that is essential to exploration of deep space.
Power From the Isotopes
The United States is trying to generate plutonium fuel for the first time in 25 years. Will it succeed?
We report on the current state of Plutonium-238 production in the United States, a crucial fuel source for planetary exploration spacecraft.
Plutonium-238 is Crucial for Space Exploration – and it's Running Out
The Planetary Society works to maintain plutonium availability for deep space missions
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.
The Energy Department is Full of Hugely Wasteful Spending, But Can't Afford to Make Plutonium for NASA
Congressional Energy Committees Should Focus More On Waste, Less on Making NASA Pay
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
NASA's Europa Mission Concept Rejects ASRGs -- May Use Solar Panels at Jupiter Instead
Untested technology is too risky
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.
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.
[Updated] Senate Bill Restores $223 million to NASA's Planetary Science Division
A step in the positive direction, but far from certain
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.

I just got the following email from the American Geophysical Union (AGU), requesting anyone whose Congressperson sits on the Appropriations Committee to place a phone call to support the production of Plutonium-238, the isotope of plutonium that powers spacecraft that cannot run on solar power.
