Planetary Radio: Space Exploration, Astronomy and Science

What would nation-states do in response to a signal from an alien intelligence? Would they compete for status and control of the message, or hope to gain some technological advantage from its contents? Or would the world shrug its shoulders and move on? Professor Jason Wright, Director of the Penn State Extraterrestrial Intelligence Center, joins the show to discuss a new paper proposing a more nuanced and positive view of world behavior given a potential SETI detection, and how the most likely message we receive may be more ambiguous than we imagine.

The Stratospheric Observatory for Infrared Astronomy (SOFIA) made its last flight on Sept. 30, 2022. Astronomer Margaret Meixner was onboard as the huge telescope built into a 747 aircraft ended its observations of the universe. Margaret joined us earlier that day to celebrate the great successes of this unique instrument and its team.

They did it! The Double Asteroid Redirection Test (DART) spacecraft scored a direct hit on Dimorphos. We’ve got the thrilling last moments before impact, followed by an exclusive, triumphant conversation with DART Coordination Lead Nancy Chabot. Then we’ll go from spectacular success to spectacular beauty as we meet extraordinary space image processor and artist Judy Schmidt. Bruce Betts salutes the DART mission with this week’s space trivia contest.

We are less than a week from the DART spacecraft’s impact on asteroid moonlet Dimorphos as this episode is published. Mission Coordination Lead Nancy Chabot gives us a status update and a preview of what to expect during the September 26 encounter. Watching the smackdown from a few kilometers away will be LICIACube. Simone Pirrotta, program manager for the Italian Space Agency’s little cubesat, tells us about his high hopes. We’ll also visit NASA’s Jet Propulsion Lab to hear the exciting announcement of organics discovered and collected by the Perseverance rover on Mars. All this and a new What’s Up space trivia contest.

More than 100,000 came to the Kennedy Space Center hoping to see Artemis 1 head for the Moon on August 29. Among them were leaders of the European Space Agency (ESA), the German Aerospace Center (DLR), and the Italian Space Agency (ASI). They sat down with Mat Kaplan for conversations about the international collaboration behind the Artemis program, along with some of the other brilliant successes they have achieved. We also celebrate the 60th anniversary of President John F. Kennedy’s speech that set the United States on course for the Moon. There’s a JWST T-shirt waiting for the winner of the new What’s Up space trivia contest.

As we wait for the launch of Artemis 1, we explore the Artemis Accords: a shared set of principles for exploring space, signed now by more than twenty nations. The accords outline a set of peaceful behaviors and shared values, including the open sharing of scientific data, safe disposal of orbital debris, commitments to mutual aid, and practices for using space resources and preservation. Mike Gold, former Associate Administrator of Space Policy and Partnerships at NASA, helped draft these accords and joins the show to share why they're important, how they came together, and the immense practical benefit of having global norms in space. Casey and Mat also discuss the context and meaning of the Artemis 1 mission following their visit to Kennedy Space Center in Florida.

We now know the rough outline of how NASA and the European Space Agency (ESA) expect to get the samples collected by Perseverance off Mars and into labs on Earth. Mars Sample Return Program Manager Richard Cook of JPL will take us through the intricate and audacious steps required. The plan now includes two Mars helicopters! Trickster Bruce Betts, chief scientist of The Planetary Society, provides the surprising answer for his latest space trivia question. Apollo 11 was not the first liftoff from another world!

Astronomer Jane Greaves and her worldwide team have had quite a ride. It has been two years since the Cardiff University professor announced evidence of phosphine in the atmosphere of Venus. Many scientists were and still are skeptical, but Jane is back with more data, including some that she shares with us first. She and Mat talk about what this could mean. Phosphine-belching Venusian penguins are very unlikely, but we want your artists’ concepts of them! That’s in addition to yet another space trivia contest from Bruce Betts.
