SpaceX has been requesting HiRISE images from an area called Arcadia Planitia as potential landing sites for their Starship vehicle. Dr Ali Bramson, a planetary scientist at the University of Arizona’s Lunar and Planetary Lab and expert on the region, joins Jake to talk about what’s going on there and why SpaceX might be interested.

The WeMartians Season 3 Mission Patch

This is the Season 3 (2018) commemorative WeMartians Mission Patch. We’ve partnered with space fan and talented graphic artist Beth Kerner to put together a custom, 4-inch, sew-on embroidered patch. It’s limited edition, with a print-run of just 100. And you can get one for yourself starting today! They’re just $17 USD, and shipping is free anywhere on Earth (Mars is extra, though). If you’re a Station-level or higher patron, your permanent store discount applies, too!
The patch captures the broad narratives of our third season of podcasts. It includes the Falcon Heavy inaugural flight, the InSight launch and landing, and the global dust storm that ended the Opportunity mission.
