Top NASA Scientists Grapple with Budget Cuts
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.
The Sorry State of Planetary Science Funding In One Chart
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.
The ASRG Cancellation in Context
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.
Why We're Writing the President (& Congress) Now
Decisions about both the 2014 and 2015 budgets are happening soon.
An Open Letter to President Barack Obama
Bill Nye writes President Obama arguing that the President should embrace a bold future of planetary exploration.
What's Going on With Planetary Science Research?
Budget cuts mixed with a new way to fund science could disproportionately impact the next generation of planetary scientists.
Call Your Representatives, Save Our Science
I called one of my Senators earlier today. Before that I called my representative. It was pretty easy.
NASA Just Cancelled its Advanced Spacecraft Power Program
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.
ARTEMIS Mission Update
ARTEMIS is a mission that retasked two probes from the 5-spacecraft Heliophysics constellation THEMIS to study the interaction of the Moon with the space plasma environment.
Will We Lose Cassini’s "New" Mission at Saturn to Budget Cuts?
NASA’s shrinking budgets for planetary exploration may force it to decide between continued funding for the Saturn Cassini mission and the continued funding for its Mars missions.
Europe Bypasses Solar System for Upcoming Science Missions
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.
Laser Bees Update
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.
Power From the Isotopes
We report on the current state of Plutonium-238 production in the United States, a crucial fuel source for planetary exploration spacecraft.
Mars Needs Plutonium! (And so do Saturn, Uranus, Neptune and Points Beyond)
Society Advocacy and Outreach Coordinator Casey Dreier visits Planetary Radio with the tale of an element that is essential to exploration of deep space.
One More U.N. Step Forward on NEOs
This week, the United Nations will move one step closer to an international response to the threat from near Earth objects (NEOs).
Announcement for DPS 2013: New plan for "Agency Night" features...me!
I'll be representing The Planetary Society on a quickly-replanned panel at tomorrow's Division for Planetary Sciences Meeting Agency Night, in the absence of any representatives from federal funding agencies.
Google+ Hangout with ESA about Europe's Mars exploration
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.
Government shutdown closes 3 of 4 National Radio Astronomy Observatories
The shutdown of the federal government continues to claim casualties. Today, the Green Bank Telescope, Very Large Array, and Very Long Baseline Arrays all shut their doors, blinding us to the radio sky and scuttling long-term research projects.
NASA's MAVEN Mission Spared from Shutdown
Launch preparations will resume for NASA's MAVEN spacecraft, due to launch to Mars on November 18th. Work had previously been suspended, potentially causing the spacecraft to miss its once-every-26-month launch opportunity.
Origami Nanosats: The Future of Space Telescopes?
We interview Dr. Franck Marchis from the SETI Institute about nanosats that can unfold in space to create sensitive telescopes that are orders of magnitudes cheaper than current hardware.
