1 Four small rooms， a gym and a lot of redsand—NASA revealed its new Marssimulationhabitat， in which volunteers will live for a yearat a time to test what life will be like on futuremissions to Earth’s neighbor.

2 Four volunteers will begin the firsttrial this summer， during which NASA plans to monitor their physical and mentalhealth 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”onMars.

3“We can really start to understand how we’re supporting them with what we’reproviding them， and that’s going to be really important information to making those criticalresource 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 160squaremeterhabitat is also designed to recreate environmental pressuresthat future visitors to Mars could face. Examples of this will be carrying out activities withlimited resources， being isolated and experiencing equipment failures.

5 Several pieces of equipment astronauts would likely use are scattered around the redsandcoveredfloor， including a weather station， a brickmakingmachine and a small greenhouse.There is also a treadmill （跑步機） on which the makebelieveastronauts will walksuspended 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 volunteers who will take part in the first experiment have not yet been named. NASA says the processof 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.

7 The habitat has another special feature： it was 3Dprinted.

8“That is one of the technologies that NASA is looking at as a potential to build habitaton other planetary or lunar surfaces，”Douglas said.

9 NASA is in the early stages of preparation for a mission to Mars， though most ofthe agency’s focus is on the upcoming Artemis missions， which aim to return humansto the Moon for the first time in half a century.
