NASA is planning to send humans back to the moon by 2020. It is also looking ahead to the first manned landing on Mars.
A new facility in Texas will allow people to live in an environment similar to Mars. It has a 3D printer, a kitchen, a living room, and even a garden. It will be used to conduct experiments on how humans would behave on the surface of Mars. The facility will be open to the public until the end of the year, when it will be fully operational.
