Top NASA Scientists Grapple with Budget Cuts
A struggle to keep new missions coming
Ellen Stofan, NASA's Chief Scientist, and John Grunsfeld, the head of the Science Mission Directorate and a Hubble repair astronaut, highlighted recent NASA science discoveries at the American Geophysical Union conference in San Francisco.
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.
The European Space Agency has selected two astrophysics observatories as its next large science missions, overlooking every proposed planetary mission. ESA's current selection of planetary missions, however, means it will still be a major player in solar system exploration for the next two decades.
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.

The European Space Agency invited me to join Mars Express project scientist Olivier Witasse, and spacecraft oeprations manager Michel Denis for a Hangout on Europe's recent and future exploration of Mars and Phobos.
The European Space Agency will announce two major science missions this November, one of which is likely to be devoted to solar system exploration.
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.
For those wishing to bore into more details of our Laser Bees project itself, graduate student Alison Gibbings from the University of Strathclyde has sent their technical paper that resulted from the 2013 Planetary Defense Conference.
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.
Planetary Society Hangout: Arkyd Telescopes, Planetary Resources, Chris Lewicki
Thursday, Jun 27, noon PDT/1900 UTC
We talked to Chris Lewicki, President of Planetary Resources, about their upcoming Arkyd telescopes including one for the public, asteroid mining, and more. Hosted by Bruce Betts with Jennifer Vaughn.

The Hangout has been postponed because of technical difficulties. Stay tuned for rescheduling information.
NASA Administrator Highlights Advanced Propulsion Systems at JPL
An ion engine will be used on the proposed asteroid retrieval mission
Charles Bolden stopped by JPL to highlight research being done on advanced propulsion techniques that would be used in the proposed asteroid retrieval mission.
This week Jon Lomberg is attending the Starship Century conference, which brings together scientists, writers, and futurists to imagine the future of interstellar travel. Here he reports on presentations by Freeman Dyson, Peter Schwartz, Robert Zubrin, Geoff Landis, Neal Stephenson, and Patti Grace Smith.
