Editor's Note: In the Utah desert, scientists attempt to recreate what a real-life mission to Mars might be like. In January, SPACE.com contributor Elizabeth Howell hitched along with Crew 133 for the ride. She sends this look back at hidden messages crew changes on a simulated Red Planet.
The Mars Desert Research Station is a 1,200-square-foot facility in the middle of the Utah desert and is the property of the Mars Society. Crews staying out here, however, are responsible for keeping it clean and safe for simulated missions to the Red Planet.
My crewmembers went over every square inch of this space in our time there. We pulled out the shelves of equipment in the "EVA room" (extra-vehicular activity room) and vacuumed near the walls. We swept out our rooms and wiped down the shelves.
Along the way, we discovered some interesting messages. Most are functional, but there are a few fun surprises for crews to discover.
The first crew for MDRS came here in 2002. The facility has been through a few renovations since that time. For example, some painting a summer or two ago eliminated the tradition of putting crew patches on the doors. ("It looks cleaner," MDRS director Shannon Rupert told SPACE.com in December.)
Certain messages do remain scattered around the MDRS habitat. A large reason for that is institutional memory. Crew handovers are brief, lasting a few hours, and it's possible that somebody could forget that it's not a good idea to store items near the circuit breaker panel, for example.
Other messages are more humorous. On a shelf in the great room downstairs, the word "Science" and an arrow points to the items on the shelf. "Non-Science" points to the wall, where presumably it would be more difficult to do that kind of work.
The crew "staterooms" or bedrooms also have murals from people presumably looking for something to do during the two weeks here. The best among them is a flaming astronaut.
