1. Why does the author point out that the CHAPEA base was built using a 3-D printer?
The author points out that the CHAPEA base was built using a 3-D printer to show one way NASA is trying to simulate a stay on Mars. On an actual mission to Mars, astronauts would have to use a 3-D printer to build their home base.

2. The article says that the CHAPEA team is facing some of the same problems that astronauts on Mars would face. Describe two examples.
Sample response: The CHAPEA team does not have easy access to fresh fruits and vegetables, so they have to grow their own, just like astronauts on Mars would have to do. The CHAPEA volunteers also have to wait more than 40 minutes for a response from NASA when they have a question—just as astronauts on Mars would.
