TWiS 130: Dogs on Mars, Snakes on the Moon - Mars Sample Return and VIPER

1 hour 9 minutes

NASA's planetary exploration program is in trouble. The Mars Sample Return program is verging on cancellation, and the VIPER mission to the moon already has been. Both are critical precursors to human exploration of these places, as Dr. Jim Bell of Arizona State University will tell us. We need to know more about the surface of Mars--with direct, in-the-lab studies of Mars rocks--and we certainly need to understand where the volatiles--another name for water and other resources of value--are on the moon. And, if you're the US government, you'd like to do both before China does--which is likely not far off. Does it matter who achieves these things first? And specific to the US, what role might private companies and individuals play in the drama?

Headlines:

SpaceX's Crew-9 mission is set to launch two astronauts to the International Space Station on Saturday, September 28th, with the primary objective of bringing back the Starliner astronauts who have been on the station for an extended period.

Earth is set to temporarily capture a small asteroid, 2024 PT5, which will remain in close proximity to our planet from September 29th to November 25th, providing scientists with an opportunity to study a near-Earth asteroid up close as it performs a de-facto flyby.

Main Topic - Discussion with Dr. Jim Bell:

Jim Bell discusses his early fascination with space exploration, inspired by the Apollo missions and Carl Sagan's acclaimed 1980s series "Cosmos," which led him to pursue a career in planetary science.

The decadal survey process is explained, highlighting how it helps align the scientific community's priorities with NASA's mission planning and funding decisions.

The challenges faced by the Mars Sample Return mission are discussed, with Jim expressing optimism that NASA will find a way to overcome the current budgetary hurdles and complete this groundbreaking mission.

The cancellation of the VIPER lunar rover mission is addressed, with the hosts and guest emphasizing the importance of this mission for future human exploration of the Moon and the need for more transparency in NASA's decision-making process.

Jim shares his perspective on the increasing involvement of commercial space companies in planetary exploration, stressing the importance of developing sustainable business models to ensure the long-term viability of these ventures.

The conversation touches on the balance between NASA's priorities, such as the Artemis program, and the funding allocated to robotic scientific missions, with Jim highlighting the need for better communication and collaboration between the human spaceflight and robotic exploration divisions of NASA.
