Planetary Society board member and Caltech/JPL research scientist Bethany Ehlmann discusses how the Mars 2020 mission will search for life on the Red Planet.
We talk with two of our 2019 Shoemaker NEO Grant winners, who received funding to help find, track, and characterize potentially hazardous asteroids.
Get ready for season 4 of The Expanse with Daniel Abraham and Ty Franck, who write the books and co-produce the shows under the name James S. A. Corey.
As the 2010s come to a close, Marcia Smith, the founder of Space Policy Online, rejoins the show to explore the most significant and impactful space policy decisions of the 2010s.
Chris Carberry traces the history and future of alcohol in space through his new book.
Organizations are using the microgravity environment of the International Space Station to develop unique new products. One of them is Kentucky-based Space Tango. We’ll meet its chairman and co-founder and the woman who manages its Tangolab.
Looking for the perfect space book or gift for your favorite space fans? We’ve got the lists.
A fun conversation with the leader of the Cassini imaging team, and an audio tour of the transit of Mercury with astronomer Jay Pasachoff.
Astrophysicist Javier Peralta, a team member on Japan's Akatsuki mission, takes us deep into Venus's thick, fast-moving clouds.
How can a simple report—just words on a page—lead to creation of a spacecraft? We explore how a 2019 report on the need for a dedicated, space-based telescope to find threatening near-Earth asteroids motivated NASA to pursue that very mission.
Mat Kaplan talks with Sasha Sagan about For Small Creatures Such as We, and later joins Bruce Betts to offer the book in the new What’s Up space trivia contest.
The way minerals form in different Earth environments may hold the answer.
October 1st kicked off federal fiscal year 2020—a day that should also have kicked off a new budget for NASA. But Congress has not funded the space agency yet, instead passing a temporary stopgap measure to keep the government open until November 21st. Brendan Curry, The Planetary Society's Chief of D.C. Operations, joins the show to discuss the latest political developments in Washington, good news for planetary defense, and how the funding delay could spell trouble for the space agency's 2024 lunar goal.
Planetary scientist Vishnu Reddy studies space objects ranging from satellite debris to planet-killing asteroids. He shares the status of our effort to avoid the fate of the dinosaurs in a conversation with host Mat Kaplan. Did you know fruit flies were first in space? That’s just one of the random space facts you’ll absorb in this week’s What’s Up segment with Bruce.
Brad Pitt sets out across the solar system to save Earth in the new space epic. Host Mat Kaplan enjoys a far-reaching conversation with co-screenwriter of Ad Astra that touches on the film’s meaning, the mythic journey of its protagonist, its spectacular images, and where it strays from known science. Registration for the Planetary Society’s 2020 Day of Action in Washington DC is open! Chief Advocate Casey Dreier has the lowdown. You might win a beautiful, rotating MOVA Earth globe in this week’s What’s Up space trivia contest. Hey! That’s LightSail 2 floating above our pale blue dot.
The biannual Starship Congress attracts starry-eyed believers in humankind’s destiny among the stars. We talk with several of them about their ideas for technologies and science that may help pave the way. Science fiction author David Brin dropped by the Congress and spends a few fun and speculative minutes with us. The September Equinox edition of The Planetary Report is ready for all to read. Editor Emily Lakdawalla gives us a sneak peek. The Milky Way has at least 54 satellite galaxies? Who knew? Bruce Betts, that’s who.
This US research center has been part of more than 200 space missions, but it’s not a NASA facility! The Los Alamos National Laboratory in New Mexico gave the Voyager spacecraft their power sources, is building nuclear generators for future Martians, and accidentally invented the field of High Energy Astrophysics.
As NASA struggles to return humans to the Moon by 2024, it's worth asking: why did it stop in the first place? Space historian John Logsdon joins the show to discuss the politics behind the decision to abandon the Moon in 1972. Casey and Mat also discuss the proposal to offer a $2 billion prize for sending humans back to the Moon and establishing a base there, and why that's not good public policy.
First we return to JPL for an update on the Mars Helicopter that has just been attached to the belly of the 2020 Mars Rover. Then it’s across the pond for a review of the amazing science coming from the Rosetta mission that spent years exploring comet 67P/Churyumov-Gerasimenko. We wrap things up with another What’s Up view across the solar system and beyond.
