Book Club Edition: Planetary Society Chief Scientist Bruce Betts’ latest for kids

Leroy Chiao was one of the youngest astronauts ever selected. He would spend 229 days in low-Earth orbit, command the International Space Station, and perform three spacewalks. His book, “Dinner with an Astronaut,” chronicles his journey from Chinese American kid born in Milwaukee, Wisconsin to the literal heights of space achievement. Leroy also shares his thoughts about topics as diverse as engineering, Chinese food, and UFOs/UAPs in this entertaining conversation with The Planetary Society’s Mat Kaplan.

Book Club Edition: Dinner With an Astronaut by Leroy Chiao

Japan’s Martian Moons eXploration mission, MMX, is about to set out for Phobos and Deimos, the two small moons of Mars. If all goes well, it will bring the first-ever sample from the Martian system back to Earth. Asa Stahl, public outreach astronomer at The Planetary Society, explains why these strange little moons are still such a mystery and what a piece of Phobos could reveal. Then Kris Zacny, vice president and senior research scientist at Honeybee Robotics, tells the story of PlanetVac, a sampler that Planetary Society members helped get off the ground more than a decade ago. From its first tests in a vacuum chamber to the surface of the Moon aboard Firefly Aerospace’s Blue Ghost lander, PlanetVac has come a long way, and its descendant is now headed for Phobos. Plus, Bruce Betts, chief scientist at The Planetary Society, joins us in What’s Up.

From the Mojave to Phobos: PlanetVac rides with MMX

Can you buy science the way you buy a rocket launch? NASA is exploring the idea of “science as a service,” asking industry how commercial companies could provide scientific data and capabilities for Earth science, space weather, and astrophysics. But the concept isn’t new. It’s the latest chapter in a four-decade effort to commercialize space science that stretches back to the brief, troubled privatization of Landsat in the 1980s. Casey Dreier is joined by Jack Kiraly, chief of advocacy for The Planetary Society, and Britney Schmidt, planetary scientist, astrobiologist, and Planetary Society board member, to unpack what commercial science services can and can’t deliver.
