Scientists Enter Hawaii Dome In Eight-Month Mars Space Mission Study (reuters.com) 94

Posted by BeauHD from the study-learn-and-repeat dept.
An anonymous reader quotes a report from Reuters: Six scientists have entered a dome perched atop a remote volcano in Hawaii where they will spend the next eight months in isolation to simulate life for astronauts traveling to Mars, the University of Hawaii said. The study is designed to help NASA better understand human behavior and performance during long space missions as the U.S. space agency explores plans for a manned mission to the Red Planet. The crew will perform geological field work and basic daily tasks in the 1,200-square-foot (365 m) dome, located in an abandoned quarry 8,000 feet (2.5 km) above sea level on the Mauna Loa volcano on Hawaii's Big Island. There is little vegetation and the scientists will have no contact with the outside world, said the university, which operates the dome. Communications with a mission control team will be time-delayed to match the 20-minute travel time of radio waves passing between Earth and Mars. "Daily routines include food preparation from only shelf-stable ingredients, exercise, research and fieldwork aligned with NASA's planetary exploration expectations," the university said. The project is intended to create guidelines for future missions to Mars, some 35 million miles (56 million km) away, a long-term goal of the U.S. human space program. The NASA-funded study, known as the Hawaii Space Exploration Analog and Simulation (Hi-SEAS), is the fifth of its kind.

        We only spent a couple months at a time making holes in the ocean. Plus we had a lot more possible social interactions (100+ in a boat, as opposed to six in the dome).

          Many subs have had smaller crews, and nearly all of your interactions are with a few people at your work station.

          But there is another huge psychological consideration that makes a sub much more like a space flight: You can't quit. No matter what, you are in for the duration. The people in this dome can quit and walk out anytime they want. They likely won't, but the ability to do so makes an eno

              I wonder if they should work with pharma and come up with some new and improved hypnotics for a Mars journey. It might makes sense to have long-haul astronauts "zoned out" for several hours per day. They could keep a patch or some kind of autoinjector connected with a drug to counter-act it in case of emergency.

        This is different from a submarine in some important ways. On a Submarine, you have many dozens of people to interact with. You are physically confined, but you have some social variety. Your mission is dangerous, but you have the comfort of knowing that it's been done before. Tours are, IIRC, 6 months long.

        A Mars expedition is different. You're going to train with these people continuously for at least 5 years. During that time you'll constantly be on your best going-to-church-with-grandma behavior and never speak up about grievances because your actions are being monitored ad nauseum by a legion of shrinks. Then you finally get the mission go and you spend (optimistically) 3 months in a space the size of a minivan. Remember your last trip in a minivan? Imagine being trapped in it for 3 months with 5 other people while NASA is scheduling your day down to 15 minute increments.

        If a thousand things you can't control happen to go right then you land on Mars. EVA suits on, and you finally escape that (obscenity laden) capsule. You see a horizon for the first time in what feels like forever. Then you work your ass off for a month and have to climb back in that (expletive) minivan for a risk-laden trip back home that takes even longer than the trip to get there. ... and during the entire trip you don't have a single shower.

        It's not "exactly" like life on a submarine, is it?

      Unfortunately, they will emerge from their Hawaiian Dome to find that US President Mark Zuckerberg has purchased all the land surrounding the dome, and turned it into a sort of Dr. Moreau island, where they will need to play through a "The Most Dangerous Game" / "Escape from New Your" scenario.

      Under Zuckerberg, American folks will be looking back to the Trump Presidency as, "The good old days" . . .

    20 minute delay? Not even close to accurate. Due to the different elliptical orbits of the Earth and Mars, the distance can vary between 55 million km and 400 million km, with a corresponding light-speed delay of 3 and 22 minutes respectively. Even at its average distance of 225 million km, the delay would be 12.5 minutes. It would sure be nice if the people who write these articles and posts actually took more than about 3 seconds to think about what they're writing. Sigh.

  • The gravity on Mars s 38% less than Earth.

    Of course, you still have to take into account weightlessness on the trip to Mars but I think the iInternational Space Station has that covered. Considering that once you leave Earth magnetic field you are going to get allot of radiation from the sun so you need protection there. When you get to Mars the only safe place is underground or in radiation proof pressurized housing since the atmospheric pressure on Mars is about 0.6% of Earth 's at sea level.

    This seems to simulate life ON Mars, rather than travelling TO Mars. Big difference: on the journey there is far less to do than upon arrival on the red planet. Boredom is what gives rise to tensions, having (hopefully interesting) things to do is what keeps you happy.
