This news is about six people. They are three men and three women. They move to a dome. This dome is near a volcano. The volcano is in Hawaii and it is not active.

This environment is like the environment on Mars. If the people want to go outside, they must wear a spacesuit. The team will be together for one year.

However, a mission to Mars will be even longer. NASA says that it can take from one to three years.

Difficult words: dome (a building which has the shape of a ball cut in half), environment (the outside; the space where you live), will (this means “in the future”).

You can read the original story and watch the video in the Level 3 section.
