Moonwalking on Mauna Loa. That’s been the secret for the astronaut candidates of the HI-SEAS habitat atop the Hawaiian volcano, and in the present day, staff members shared the most recent updates on their excessive mission on the European Geosciences Union’s basic meeting.
HI-SEAS, or the Hawaii House Exploration Analog and Simulation, is a mock extraterrestrial base that has been operational since 2013. It gives scientists, engineers, and members of different fields keen to chop their space-traveling tooth the chance to stay on the mountain. The astronauts-in-training stay 8,200 ft up the mountain for as much as a 12 months, conducting enterprise as they might on a everlasting base on the Moon or Mars. Their work gives perception on how people would truly handle to stay off-planet sooner or later.
“There may be a lot that we nonetheless have to be taught from how people work together below these difficult circumstances, significantly on learn how to create an area household atmosphere for everybody to get alongside and work collectively nicely,” stated Michaela Musilova, the director of HI-SEAS, in an e mail. “Then, we additionally want to determine learn how to remedy issues which are prone to happen on long-duration missions, which is one thing that has loads of room for enchancment.”
To that finish, HI-SEAS not too long ago ran an experiment in hydroponics to develop lettuce throughout the habitat, an endeavor performed on the Worldwide House Station in 2015. When storms arrive on the islands, the staff places the habitat in low-power mode, because it depends on a solar-powered generator.
The analog astronauts, as they’re known as, don’t get bombarded with radiation and don’t cope with microgravity, however they do gown the a part of lunar or Martian explorers. Group members put on area fits every time they enterprise past the cramped 1,200-square-foot habitat they share, full with a heads-up show and restricted oxygen provides. Musilova stated a number of the greatest technical challenges come on these journeys outdoors the bottom, the place fits constructed to guard astronauts in “area” will be clunky for the geological, volcanological, and astrobiological work the staff performs. These excursions happen on the Martian-like soil of Mauna Loa and within the volcano’s lava tubes, canals the place molten rock as soon as flowed.
“The work atmosphere in lava tubes may be very difficult,” Musilova stated. “Analog astronauts must descend into caves with sharp rocks throughout them. Generally they should crawl in a number of the slender elements of tubes or climb up close to vertical partitions. Then, they should carry out analysis, comparable to amassing delicate microbiological samples or drilling with particular gear.”
Together with different simulated habitats at NASA’s Johnson House Middle and elsewhere, HI-SEAS is a part of the intensifying effort to get people prepared for dwelling on different worlds, which may nicely be quickly. NASA not too long ago chosen SpaceX as the corporate to construct its Artemis lunar lander. In some unspecified time in the future, our visits must change into stays if human area exploration is to transcend its 20th-century heyday.
