Making oxygen from the Martian atmosphere will be essential if humans are ever to visit and work on the Red Planet, and the MOXIE experiment will soon show us how.
Two pioneering Mars orbiters are still doing great work above the Red Planet, while the first operational Crew Dragon spaceship has delivered four astronauts to the International Space Station.
Georgetown University planetary scientist Sarah Stewart Johnson chronicles the long history of our fascination with Mars and the possibility of life there, culminating with Perseverance, the new rover now headed there.
SuperCam principal investigator Roger Wiens shares how his new and improved laser-based spectrometer will help look for past life in Jezero Crater, while its microphone lets us listen to the Red Planet.
Our special guests are the leaders of the Emirates Mars Mission whose Hope spacecraft is now headed for the Red Planet.
The United Arab Emirates is headed for Mars as comet NEOWISE speeds back to the outer reaches of the solar system, and three white papers address the future of planetary science and defense.
Join the mission’s deputy project scientist as the Perseverance rover prepares to search for life on the Red Planet.
The leader of the Mastcam-Z team talks about how the best cameras ever on the surface of Mars will help us explore a region that could once have supported life.
China has big plans for a space station, exploration of the Moon and Mars, and possibly a mission that will follow Voyager beyond the edge of the solar system.
After a special message we present highlights of the successful arrival at the International Space Station of the Crew Dragon spacecraft, followed by a visit to chilly Mars with planetary scientist Edgard Rivera-Valentin.

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.
The way minerals form in different Earth environments may hold the answer.
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.
Rick Davis is the perfect person to co-lead NASA’s Mars Human Landing Sites Study. No one is more devoted to putting human bootprints on the Red Planet. He returns to Planetary Radio for this inspiring and informative conversation about our progress. Bruce Betts leads off What’s Up with another brief LightSail 2 update.
