This week on Aspiring Martians, we’re doing something special.
Just before the government shutdown, NASA worked with us to make sure we could sit down with members of the CHAPEA 2 crew — and two days after the hatch sealed, those interviews are now here.
The CHAPEA 2 mission officially began on October 19, 2025, when four volunteers — Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer — entered NASA’s Mars Dune Alpha habitat at Johnson Space Center in Houston. For the next 378 days, they’ll live and work as though they’re on Mars, facing communication delays, isolation, limited resources, and simulated spacewalks — all to help NASA understand how humans might live and thrive on the Red Planet.
In this exclusive double episode, Joe speaks first with Matthew Montgomery, CHAPEA 2’s Science Officer — a hardware engineer from Los Angeles whose work spans robotics, lighting systems, and controlled environment agriculture. Then, in part two, Joe talks with James Spicer, the mission’s Flight Engineer — a technical director with deep experience in spacecraft systems, satellite communications, and aerospace design.
Together, they discuss how their love of science and exploration began, what it’s like to commit to a full year of isolation, how they see the future of Mars exploration, and what keeps them motivated when the sky overhead is simulated and Earth is just a signal delay away.
It’s an inspiring look at the people helping pave the path to Mars — from inside a habitat built for the future.
A huge thank you to Matthew and James for joining me today and sharing their insights and imagination, to Kelsey over at NASA for coordinating all of this, to Nick Thorburn for our stellar theme music, to Ceci Giglio for the beautiful graphics, to RDan, Leila, Inka, and Carl for admining the FB group, and to my family for always supporting this journey — even when the dinner table becomes a Mars landing debate.

Ruthie's Table 4
For more than 30 years The River Cafe in London, has been the home-from-home of artists, architects, designers, actors, collectors, writers, activists, and politicians. Michael Caine, Glenn Close, JJ Abrams, Steve McQueen, Victoria and David Beckham, and Lily Allen, are just some of the people who love to call The River Cafe home. On River Cafe Table 4, Rogers sits down with her customers—who have become friends—to talk about food memories. Table 4 explores how food impacts every aspect of our lives. “Foods is politics, food is cultural, food is how you express love, food is about your heritage, it defines who you and who you want to be,” says Rogers. Each week, Rogers invites her guest to reminisce about family suppers and first dates, what they cook, how they eat when performing, the restaurants they choose, and what food they seek when they need comfort. And to punctuate each episode of Table 4, guests such as Ralph Fiennes, Emily Blunt, and Alfonso Cuarón, read their favourite recipe from one of the best-selling River Cafe cookbooks. Table 4 itself, is situated near The River Cafe’s open kitchen, close to the bright pink wood-fired oven and next to the glossy yellow pass, where Ruthie oversees the restaurant. You are invited to take a seat at this intimate table and join the conversation.
