1
Four small rooms,a gym and a lot of red
sand —NASA revealed its new Mars­simulation habitat,in which volunteers will live for a year
at a time to test what life will be like on future missions to Earth s neighbor.
2
Four volunteers will begin the first
trial this summer,during which NASA plans to monitor their physical and mental health to have a better understanding of humans courage for such a long isolation.With that data,NASA will have a better understanding of astronauts “resource use ”on Mars.
3
“We can really start to understand how we re supporting them with what we re
providing them,and that s going to be really important information to making those criti­cal resource decisions,”said Grace Douglas,an expert,on a press tour of the habitat.
“Such a distant mission comes with ‘very strict mass limitations ’,”she added.
4
The 160­square­meter habitat is also designed to recreate environmental pressures
that future visitors to Mars could face.Examples of this will be carrying out activities with limited resources,being isolated and experiencing equipment failures.
5
Several pieces of equipment astronauts would likely use are scattered around the red
sand­covered floor,including a weather station,a brick­making machine and a small green­house.There is also a treadmill (跑步机)on which the make­believe astronauts will walk suspended from straps to simulate the red planet s lesser gravity.
6
Four volunteers will use the treadmill to simulate long trips outside to explore Mars,
collecting samples,gathering data or building infrastructure (基础设施).The

who will
take part in the first experiment have not yet been named.NASA says the process of choosing the individuals will follow the same guidelines that are used to choose astro­nauts.The team members will be expected to have rich backgrounds in science,technol­ogy,engineering and math.
7The habitat has another special feature:it was 3D­printed.

“That is one of the technologies that NASA is looking at as a potential to build habi­tat on other planetary or lunar surfaces,”Douglas said.
9
NASA is in the early stages of preparation for a mission to Mars,though most of
the agency s focus is on the upcoming Artemis missions,which aim to return humans to the Moon for the first time in half a century.
