Space Policy Edition: Real and Acceptable Reasons for Space Exploration

Recommendations made in the 2023-2032 Planetary Science and Astrobiology Decadal Survey will be revealed on April 19. One of the 11 design studies commissioned for the survey explores a flagship mission to Neptune. The Neptune Odyssey project engineer is Brenda Clyde. Her colleague, Kirby Runyon, is the project scientist. They’ll take us inside this exciting concept and remind us of why an ice giant orbiter is long overdue. Even Bruce Betts and Mat Kaplan were surprised by the answer to this week’s space trivia contest. You’ll hear it and more in What’s Up.

Citizen scientists will soon have another opportunity to become part of the search for extraterrestrial intelligence, and an innovative project will use a subtle effect of sunlight to learn about near-Earth objects. These are the projects funded in the first round of The Planetary Society’s Science and Technology Empowered by the Public (STEP) grant program. We’ll meet the awardees after Society chief scientist Bruce Betts provides an overview. Bruce returns for this week’s What’s Up and the space trivia contest.

Planetary scientist Bethany Ehlmann has co-authored a paper presenting evidence that liquid surface water flowed on Mars as much as a billion years more recently than previously thought. That’s an extra billion years for possible life to have formed and thrived. We’ll also join Planetary Society editor Rae Paoletta as she explores water worlds throughout our solar system in a new article. Another great prize awaits the winner of the What’s Up space trivia contest.

It's the 50th anniversary of Pioneer 10, the first spacecraft to the outer planets. Pioneers 10 and 11 were scrappy, low-cost endeavors that blazed the path for future exploration. But the future has been expensive: outer planets missions are some of the priciest planetary probes in history. Can we get back to a pioneering spirit and increase the frequency of outer planet exploration? To find out, we talk with Mark Wolverton, author of “The Depths of Space: The Story of the Pioneer Probes,” and Scott Bolton, principal investigator for Juno, the most affordable Jupiter mission in decades. Casey and Mat also discuss the dynamic and tragic situation in Ukraine, and its implications for space.
