NASA wants to send people to Mars (火星). But before that, NASA builds a simulated (模拟的) Mars house. It is a 3D-printed house.

Four people will live in the house for one year. Experts want to know what will happen(发生) to the team. They cannot go outside. They will only have a little water to drink. They will grow vegetables inside the house. NASA will study how that affects(影响) their bodies and how they feel. NASA wants to know how the team gets along. Living in a small house can be difficult.

This is the longest study of its kind. NASA will tell us who are in the team this summer. The trip to Mars will take place in the 2030s.
