As if extremes of temperature and lack of air weren’t enough! Some scientists believe it’s space radiation that will keep humans from venturing deep into our solar system. Not so, say three teams of NASA Innovative Advanced Concepts (NIAC)-funded researchers. Each is exploring a cutting-edge approach to protecting astronauts on their way to Mars and other destinations.
After decades of mystery and investigation, after the recovery of gigabyte after gigabyte of data stored in obsolete computer formats, the whatdunit surrounding Pioneers 10 and 11 has finally reached its conclusion.
The Director of the Center for SETI Research is thrilled to have the Allen Telescope Array back in the hunt for extraterrestrial intelligence. She also tells us about SETILive.
Here's the second half of our December show recorded in front of a live audience: Mars rover updates, two more spacey songs from KJ Williams, and the big finish of Emily Lakdawalla's proof that she is not covering up evidence of aliens in our solar system! You'll also hear a brand new What's Up segment from Bruce Betts and Mat Kaplan.
We once again go before a live audience for an all Mars rover show. We've also got singer KJ Williams, Bill Nye the Planetary Guy, and Emily Lakdawalla's proof that she is not covering up evidence of aliens in our solar system!
New Mexico Cave Adventure With Penny Boston and the First International Planetary Caves Workshop
Opportunity reaches Endeavour Crater, Emily Lakdawalla visits a New Horizons science meeting about Pluto, Bill Nye discusses a planet made of diamond, and Bruce Betts and Mat Kaplan celebrate the award of a Parsec award to Planetary Radio.
Voyager 1 at the Edge of the Solar System, With Ed Stone
Talking With Mary Roach, Author of Packing for Mars
JPL engineer Daniel Gaines helped develop new software for Opportunity to autonomously select objects for close-up imaging as she races across Mars. Emily Lakdawalla is thrilled by evidence of recently active volcanos on Venus. Bill Nye salutes three decades of service by retiring Planetary Society founder Lou Friedman.
John Callas tells us why an end to Spirit's roving does not mean the end of her work on the red planet. Emily Lakdawalla looks to the other side of Mars where Opportunity is rolling up to a baby crater, and Bill Nye is head over heels for the highest ever skydive.
John Callas reports on Spirit and Opportunity, Bill Nye debates the future of humans on the Moon, and Bruce Betts looks to the Perseid meteor shower in his What's Up review of the night sky.
Bruce Banerdt provides a status report on Spirit and Opportunity. Bill Nye has something old and something new to talk about, and Bruce Betts returns from the Planetary Defense Conference in Spain with news of Near Earth Objects and other things in the night sky.
A Conversation with Elon Musk of SpaceX
Jim Bell and Bill Nye talk Spirit and Opportunity in celebration of 5 years on Mars. Emily Lakdawalla's Q&A looks forward to a Mars flyby by the Dawn spacecraft.
Longtime partner Ann Druyan is proud of NASA's new Carl Sagan Fellowships. Bill Nye has a tribute for his old professor.
JPL's Rob Manning explores just a few of the challenges of landing a spacecraft on another planet. We also get a Phoenix mission update from Emily Lakdawalla, who says not everything is going well.
Steve Squyres gives us a status report on Spirit and Opportunity, and Bill Nye comments on the rings that appear to surround one of Saturn's small moons. Last week Emily Lakdawalla told us why objects in space are round, but this time her Q&A explains why they're not.
John Callas provides a status report on Spirit and Opportunity. Emily Lakdawalla is looking at brilliant Comet Holmes in her Q&A report, and Bruce Betts also makes room for Holmes in his What's Up! review of the night sky.
Landing people on Mars will be hard, but JPL's Rob Manning and other engineers are working on solutions.
