NASA unveils a house to simulate life on Mars
Nasa on Tuesday unveiled the house in which four people will soon isolate themselves for a year to simulate life on Mars.

Four bedrooms, a gym… The house, presented Tuesday by NASA, seems banal but, from June, four people will be confined there for more than a year to simulate life on Mars. The habitat, named Mars Dune Alpha, is located at the US Space Agency’s research center in Houston, Texas.
Those who inhabit it will help prepare for a future mission to the red planet. By measuring their performance and cognitive abilities, NASA will better understand the “resources” that must be provided during this ambitious journey, explains Grace Douglas, a manager of the CHAPEA program, which supervises this experiment.
Reconstitution
A crucial point, given “the very restrictive weight limits that can be sent on these missions”, she adds. The 160 square meter house includes a vertical farm for growing salads, a room dedicated to medical procedures, a relaxation area and workstations.
An airlock leads to a reconstruction of the Martian environment. On the red sand floor are a weather station, a device for making bricks, a small greenhouse and a treadmill on which the pretend astronauts will walk suspended from straps.

“We can’t make them walk in circles for six hours,” smiles Suzanne Bell, in charge of NASA’s “Behavioral Health and Performance Laboratory” program. According to her, this mat will reproduce the effort required for physical activity on Mars, but also for collecting samples, collecting information or even building.
3D printed
The names of the voluntary prisoners are not yet known, but we already know that the team will not be made up of astronauts. They will be under stress on a regular basis, with water restrictions or equipment failures.
This house has another particularity: it was printed in 3D. “This is one of the technologies that NASA is studying to potentially build habitats on the surface of other planets or the Moon,” says Grace Douglas.
The space agency is preparing a round trip to Mars, but the big departure is not for now. This trip, which would last several years, could take place “at the end of the 2030s”, according to NASA boss Bill Nelson.
