We're looking at what's next for the future of travel to mars after scientists just simulated a year on the planet.
Six scientists spent 365 days in a dome 82-hundred feet above sea level on a volcano in Hawaii.
The experiment was designed to test what it's like for a crew to be isolated for that long.
This is actually the 3rd time so far NASA has teamed up with the University of Hawaii to test out a trip to mars, but this one was the longest yet.
Right now the University of Hawaii is recruiting crew members for its next two mars simulation missions.
One is scheduled to begin this January for eight months, and the next one starts in 20-18.
This is just one step in NASA's goal to get people to mars in the 2030's.
It has another test next month of a mockup of the spacecraft that would go into deep space.
Water impact tests like this help engineers understand how to best protect the crew and spacecraft when they return to earth from deep space missions.
