NASA’s twin ESCAPADE spacecraft have finally launched on their journey to Mars. Designed to study how the solar wind interacts with Mars’ patchy magnetic fields and drives the loss of its atmosphere, ESCAPADE is NASA’s first dual-spacecraft mission to the Red Planet and a major milestone for the SIMPLEx program’s small, low-cost planetary explorers. The mission began its voyage aboard Blue Origin’s New Glenn rocket after several weather and space weather delays, marking the vehicle’s first science launch.

We begin with Ari Koeppel, AAAS Science & Technology Policy Fellow and Space Policy Intern at The Planetary Society, who was at Cape Canaveral for the prelaunch activities. Ari shares what it was like to navigate repeated scrubs and even a powerful solar storm, along with the emotional experience of watching a spacecraft carrying an instrument he helped build begin its voyage to Mars.

Next, we are joined by Dr. Rob Lillis, ESCAPADE’s Principal Investigator and Associate Director for Planetary Science at UC Berkeley’s Space Sciences Laboratory. Rob explains how ESCAPADE aims to unravel Mars’ complex space environment using two coordinated orbiters, why its measurements are key to understanding atmospheric escape, and how its innovative trajectory made the mission possible after the loss of its original rideshare opportunity.

Finally, Dr. Bruce Betts, Chief Scientist of The Planetary Society, returns for What’s Up to talk about why Mars produces aurora even without a global magnetic dynamo.

This week on Planetary Radio, we’re sharing a special conversation from our friends at the Smart Girl Dumb Questions podcast. Host Nayeema Raza sits down with The Planetary Society’s Chief of Space Policy, Casey Dreier, to explore one of the most common questions in space exploration: Why does space matter, and is it really worth the cost?

Casey breaks down how space exploration impacts daily life, from GPS and weather forecasting to cutting-edge technologies and scientific discoveries that could reshape our future. Together, Nayeema and Casey unpack the big ideas behind NASA’s ~$25 billion budget at a moment when U.S. national priorities are shifting.

Stick around after the interview for a special U.S. Thanksgiving-week edition of What’s Up with Chief Scientist Bruce Betts.

Smart Girl Dumb Questions: Casey Dreier answers why space is worth it

There was a time when almost everyone, from Alexander Graham Bell to the Wall Street Journal, believed there was a supremely intelligent civilization on Mars, one that was probably trying to talk to Earthlings. Most of this belief could be traced to an amateur astronomer and charismatic speaker named Percival Lowell. David Baron tells this story in “The Martians: The True Story of an Alien Craze that Captured Turn-of-the-Century America,” the product of seven years of research into this strange chapter of history. He shares many of the most surprising, fascinating, and very entertaining details, including much that had been lost to history, in this book club conversation with Mat Kaplan.
