On October 31 they walked out of NASA’s Mars Dune Alpha habitat in Houston, ending the agency’s second yearlong Mars surface simulation, and NASA has now published their reflections on the year. The crew of CHAPEA (Crew Health and Performance Exploration Analog) Mission 2 were commander Ross Elder, medical officer Ellen Ellis, flight engineer James Spicer and science officer Matthew Montgomery. We covered the planned exit date and the end of the mission earlier; this is what the four say they learned. How the simulation worked The habitat is a 3D-printed structure of about 1,700 square feet inside a building at Johnson Space Center. The crew went in on October 19, 2025. Inside, they ran simulated Marswalks, flew a drone and drove a rover remotely to scout terrain and gather rock samples, kept the life-support systems running, exercised and grew crops, all while researchers logged their health and performance and rationed their supplies. What the crew said Elder, a US Air Force experimental test pilot, found the Marswalks and robotic work “uncannily similar” to flying. Suiting up, cycling through the airlock and making long traverses ate time and energy, and he came out stressing food, exercise and sleep as the things that keep a crew going. “The real magic has been the privilege and pleasure of seeing everyone come together,” he said. Ellis, a US Space Force officer, handled biological sample collection. “It would be difficult to convince someone who has never lived in isolation that most days, I don’t feel isolated,” she said, crediting her three crewmates. Her biggest lesson: “a future Mars crew requires a highly integrated ground team.” Spicer likened the year to life on a submarine. The crew tracked everything from dish soap to respirator filters, and he was surprised by how little he missed the constant stream of news and social media. Montgomery set up the habitat’s 3D printing, helped identify rock samples and ran a seed-germination test comparing a control with simulated Martian soil. “It’s really the people that make exploration possible,” he said. The year in numbers Counting both the entry day and the exit day, October 19, 2025, to October 31, 2026, spans 378 calendar days. A one-way delay of up to 22 minutes means a single question and answer could take as long as 44 minutes. NASA astronaut Jack Hathaway noted that while the crew was sealed in, he flew a 237-day space station mission and came home, so the volunteers stayed inside 141 days longer than his entire flight. Limits This was an analog mission on Earth, with four people, and the science is not in yet. Two weeks of post-mission evaluations and debriefs are meant to help researchers read the data alongside the crew’s experiences. Principal investigator Grace Douglas said the work will help NASA weigh crew health and performance risks against limited resources such as crew time, communication capacity and food and water systems. The results feed planning for NASA’s Moon Base near the lunar South Pole, the outpost behind the agency’s $10 billion cargo lander plan. “This is really the now moment for this kind of data,” said CHAPEA project scientist Sara Whiting. The first CHAPEA mission ended on July 6, 2024; this crew’s debriefs run through mid-November.
