NASA Crew Completes Yearlong Mars Habitat Simulation
· Confirmed
In Short: Four crew members emerged from a 3D-printed habitat in Houston after a yearlong Mars mission simulation.
Four crew members — Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer — emerged from a 3D-printed Mars habitat in Houston on October 31, 2026, after a yearlong simulation, according to Earthsky and NASA.
Both Earthsky and NASA reported that the crew entered the Crew Health and Performance Exploration Analog (CHAPEA) on October 19, 2025, and lived in the 1,700-square-foot 3D-printed habitat for 378 days.
Earthsky noted that the crew faced psychological challenges and had limited personal time, while NASA emphasized the importance of delayed communication with Earth to simulate real Mars mission conditions.
The crew will undergo post-mission evaluations and debriefing for the next two weeks.
NASA and Techmymoney both stated that the simulation aimed to collect health and performance data to help mitigate risks in future deep space missions.
The crew expressed gratitude for their families and supporters, with Ellis thanking her crewmates for a challenging but rewarding year, as reported by Thedebrief.
Jack Hathaway, a NASA astronaut, greeted the crew with 'Trick or treat' as they emerged from isolation on Halloween, according to The Debrief.
Despite the crew's successful completion of the simulation, Shattered noted that NASA has not yet published specific data such as crew weight changes, crop yields, power draw, or medical event counts.
The simulation's findings will be crucial for planning future lunar and Mars missions, as highlighted by Shattered and Techmymoney.
The crew's experience will provide valuable insights into the psychological and logistical challenges of long-duration space missions.
What this adds
The crew's experience in the 3D-printed habitat adds to the growing body of data from similar simulations, helping NASA refine its approach to future Mars missions.
While the crew's exact experiences varied in detail, the overall agreement on the mission's goals and outcomes underscores the importance of such simulations in preparing for deep space exploration.
Background
Four crew members — Ross Elder, Ellen Ellis, Matthew Montgomery, and James Spicer — emerged from a 3D-printed Mars habitat in Houston on October 31, 2026, after a yearlong simulation.
What's confirmed
- And after 378 days, the four crew members — Ross Elder, commander; Ellen Ellis, medical officer; Matthew Montgomery, science officer; and James Spicer, flight engineer — emerged from the 3D printed habitat in Houston on October 31, 2026.
- “I’m looking forward to pineapple,” Andrzej Stewart, the chief engineering officer of the latest NASA-funded Hawaii Space Exploration Analogand Simulation (HI-SEAS) mission, said moments before he and his crew mates feasted on fresh fruits and vegetables outside the dome.
- “We now have 24 months of 24-7 data,” HI-SEAS Principal Investigator Kim Binsted said Sunday, moments before the crew exited.
- Since 2013, some 24 specialists chosen from some 800 applicants have now put their lives on hold and simulate extended missions to Mars atop Mauna Loa.
- Also in attendance were NASA astronaut Jack Hathaway, who joined the four crew members.
- Specifically, the second Crew Health and Performance Exploration Analog mission began at Johnson Space Center on October 19, 2025.
- According to NASA, health and performance data from the simulation can help counter human spaceflight risks.
- Four crew members have lived and worked inside a 3D-printed 1,700-square-foot facility, simulating Mars mission operations, conducting simulated spacewalks, exercising, performing habitat maintenance, growing plants, and more, while operating under stressors that future deep space crews will likely experience.
What's still developing
- The crew members said that while future Mars astronauts will need to be skilled at fixing things themselves, the real challenge will be the psychological ones.
- Messages back and forth from Mars won’t be instantaneous, so it was important for NASA to learn how people can cope when they can’t immediately ask for advice.
- They said the inside of the habitat was unusually quiet.
- Entering their simulated Martian habitat last year on October 19, the crew lived and worked within a 1,700-square-foot 3D printed environment which NASA engineers designed to replicate the conditions astronauts would likely encounter during an extended Red Planet mission.
- And so, what we were doing is replicating as if the food had been pre-positioned and that the crew had no choice in what they were able to eat.

- Humans still haven’t been to Mars, but four NASA volunteers now know what it’s like to spend more than a year in a Mars simulation.
- In a July 1, 2026 notice, the agency announced the Moon and Mars Exploration Analog, beginning no earlier than August 2027.
- Afterward, an in-person subject matter expert would answer media questions as the crew stepped outside.
- Media will have the opportunity to capture the moment the crew exits the building, stepping outside for the first time in more than a year.
- Wire coverage that circulated over the weekend, including a Channel News Asia report syndicated by several outlets, said Wyche stressed that communication delays demand patience, careful planning and more independence from the crew.
- Elder said in the same coverage that the risks of going to Mars are great, but that the goal remains inevitable if people keep seeking understanding.
