"We want to know how to keep people happy and safe in space. What foods will they like? How much sleep will they need? Can they stay friends, not go crazy, and work well together for the two to three years it will take to go to the Red World and come back again? To answer these questions, six people will live in a small space-like place. They can only eat space food, and can only go outside in space clothes. When they talk to friends at home, it will be slow, because of the time it takes for their words to move through space. Light is fast, but not that fast! It will be hard, but the team is very good. We expect that they will do a great job, and give us lots of facts about how to live and work in space."
Note that three of the words in the HI-SEAS acronym are not even on Up Goer Five's list of words to use for writing simple descriptions! Well done. Soon I'll have to try to describe my research with these simple words.. wish me luck!
