What happened
NASA (the U.S. space agency) says four people reached the one-year mark in CHAPEA Mission 2. CHAPEA means Crew Health and Performance Exploration Analog. It is NASA’s ground-based study of long Mars-like stays. The announcement came on Oct. 19, 2026.
The crew members are Ross Elder, the mission commander; Ellen Ellis, the medical officer; Matthew Montgomery, the science officer; and James Spicer, the flight engineer. They entered a 1,700-square-foot, 3D-printed habitat on Oct. 19, 2025. The habitat sits inside NASA’s Johnson Space Center, a NASA research center in Houston. This is a ground simulation, not a trip to Mars. The full mission is planned to last 378 days.
How the test copied Mars
During their 365 days, the crew grew crops and managed limited resources. They worked through Mars-like communication delays. They also performed suited extravehicular activities on a simulated Martian surface. Their families could contact them only by email during the mission. Messages could face a delay of up to 45 minutes each way.
These conditions were designed to copy several problems of a distant mission. The crew had to work without instant replies from Earth. They also had to manage daily tasks inside a confined habitat.
Why it matters
NASA wants health and performance information from long-duration mission conditions. The data could show how limited food and exercise systems affect mission goals. Those goals may include spacewalks on the surface of Mars. The information could also help NASA support crew autonomy and decision-making when communication is slow.
The point is not to prove that this crew has solved Mars living. It is to identify what future crews may need to stay healthy, productive, and connected. A controlled Earth habitat lets researchers study those questions before a real deep-space mission.
What is confirmed
NASA has confirmed the one-year milestone and the main living conditions. It has also said that science teams are preparing to process the crew’s health and performance data. The announcement does not report findings from that analysis. At this stage, the schedule and the test setup are clearer than the results.
What remains unknown
We do not yet know how the crew’s health or mental well-being changed. We also do not know how the communication delay affected work and decisions. The announcement does not say which food, exercise, or support systems worked best. Those answers should come from the post-mission evaluations and debriefs.
What comes next
NASA plans for the crew to leave the habitat on Oct. 31. They will reconnect with families they have contacted only through delayed email. Then they will begin two weeks of post-mission evaluations and debriefs with NASA scientists.
The next important update will be NASA’s analysis of those records and interviews. The results could inform future missions to a Moon base and beyond. This was not a Mars landing. It was a year-long test of what people may need when Earth is far away.

💡 The gist
- Four people have lived in a Mars-like home for one year.
- NASA studied health, work, crops, supplies, and delayed messages.
- The crew is scheduled to leave Oct. 31, then begin two weeks of checks.
NASA (the U.S. space agency) runs CHAPEA (a study that copies Mars living on Earth). The habitat is inside Johnson Space Center, NASA’s research site in Houston.
The habitat is 1,700 square feet and 3D-printed. The four crew members entered on Oct. 19, 2025. They have now spent 365 days inside. The whole mission is planned to last 378 days.
Life inside copied several Mars problems. The crew grew crops and managed limited resources. They wore suits for activities on a simulated Martian surface. Their families could contact them only by email. A communication delay could last up to 45 minutes each way.
Why test this on Earth? NASA needs information before sending people far away. Scientists can study health and performance in one controlled place. They can ask how food and exercise systems affect work. They can also study how crews make decisions without quick answers from Earth.
NASA has not published the study results yet. The one-year milestone is confirmed. The data analysis is still ahead.
On Oct. 31, the crew is scheduled to leave the habitat. Then they will have two weeks of post-mission evaluations and debriefs. These talks may show what future Moon and Mars crews need.

NASA (America’s space team) made a special home on Earth.
Four people lived there for 365 days. 365 days is about one year.
It was not really on Mars. The home copied some Mars chores. The crew grew crops. They used limited supplies carefully. They wore suits outside. They pretended to walk on Mars.
Their families sent emails. The messages had a communication delay. A reply could take 45 minutes each way. So answers could not come quickly.
NASA wants to learn how people live far away. It studies their health and daily work.
The crew plans to leave on Oct. 31. Then NASA will talk with them for two weeks. They will share what felt hard. Their lessons may help future Moon and Mars crews.
