More than 50 years after humanity’s last trip to the Moon, NASA is preparing for its triumphant return as soon as 2028—and laying the groundwork for the first crewed mission to Mars. But before astronauts can venture further into space, NASA needs volunteers to spend a year pretending they’re already there.
The agency has opened applications for its next Moon & Mars Exploration Analog (MMEA) mission, a year-long simulation that recreates the isolation, confinement and day-to-day challenges of long-duration space exploration. The goal isn’t to demonstrate rockets or spacesuits, but rather, to put humans to the test.
Participants will live and work inside specially designed habitats while researchers study everything they can, from crew dynamics and mental health to habitat operations and mission procedures. The crew will carry out scheduled maintenance tasks, complete scientific experiments, respond to simulated emergencies and settle into routines that could define life millions of miles from Earth.

NASA does this because getting humans to Mars isn’t just about building a big enough rocket—it’s about making sure every aspect of life so far away from Earth is optimized for success.
Perks of the MMEA mission include virtual reality spacewalk simulations and a mandatory social media detox.
The program builds on two existing NASA analog missions: HERA (Human Exploration Research Analog), which studies the effects of isolation during spaceflight, and CHAPEA (Crew Health and Performance Exploration Analog), which simulates life on the Martian surface. The next MMEA mission is expected to begin no earlier than August 2027, giving NASA time to select and train the crew for their year of isolation.
It’s Time to Stand Up for Science
If you enjoyed this article, I’d like to ask for your support. Scientific American has served as an advocate for science and industry for 180 years, and right now may be the most critical moment in that two-century history.
I’ve been a Scientific American subscriber since I was 12 years old, and it helped shape the way I look at the world. SciAm always educates and delights me, and inspires a sense of awe for our vast, beautiful universe. I hope it does that for you, too.
If you subscribe to Scientific American, you help ensure that our coverage is centered on meaningful research and discovery; that we have the resources to report on the decisions that threaten labs across the U.S.; and that we support both budding and working scientists at a time when the value of science itself too often goes unrecognized.
In return, you get essential news, captivating podcasts, brilliant infographics, can’t-miss newsletters, must-watch videos, challenging games, and the science world’s best writing and reporting. You can even gift someone a subscription.
There has never been a more important time for us to stand up and show why science matters. I hope you’ll support us in that mission.
