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.
An interview with Bruce Murray from 2001 about his perspectives on Mars science and exploration: past, present, and future.
NASA Backs Off From Additional Planetary Cuts in 2013
Operating plan provides $1.271 billion
The final operating plan for the space agency provided $75 million more to planetary exploration than initially proposed.
August Advocacy Update: Where We Stand
The House and Senate have increased funding for Planetary Science thanks to your letters and phone calls
Planetary exploration sees strong support from both parties in the current budget process, but we have a long way to go before a budget is passed this year.
The House recently passed a NASA Authorization Bill that called for "American astronauts launching from American rockets on American soil". If we depend on international collaboration, should these policies still drive NASA policy?
Congress Rejects NASA's First Operating Plan
Attempt to Raid Planetary Science Funding Stopped
NASA's plan to raid Planetary Science funding to pay for sequester cuts in other science programs was rejected by Congress earlier this month. NASA is now working on a new plan that has yet to be submitted for approval.
NASA Administrator Bolden and the Chairman of the House Science Committee published opposing op-eds in The Hill newspaper today, illustrating the uphill battle NASA faces to sell Congress on this mission.
If we started today, how long would it take to get to Mars? With this budget, never.
Analysis of the House Science Committee Hearing on the 2013 NASA Authorization Bill
The House of Representatives held a hearing today to discuss their proposed NASA authorization bill, which would fund Planetary Science, cut Earth Science, forbid asteroid retrieval, and command NASA to pursue a path to Mars via the Moon.
Despite congressional rejection of massive cuts to Planetary Science this year, NASA has found a way to implement the cuts internally and use the money for other purposes.
The American Astronomical Society has issued a strongly worded statement against NASA's proposed elimination of its education and public outreach programs, and I agree with it.
Lars Perkins, Chairman of NAC's Education Committee, writes a defense of NASA's Education and Outreach efforts, currently facing a major cut and restructuring in 2014.
A powerful new op-ed in SpaceNews traces the inevitable decline of NASA's Planetary Science missions if the current cuts to the program are implemented.
On April 9, the current Australian government announced the first formal Australian space policy. Astronomy graduate student Michele Bannister explains what this means for the country.
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 Administration just released its proposed budget for 2014 and it contains some very bad news for NASA's planetary exploration program. Just three weeks ago the U.S. Congress rejected similar cuts proposed for planetary exploration last year. It was a clear statement of support by both Congress and the public: planetary exploration is an affordable national priority.
