Scientists will use the U.S. Navy's Kraken to simulate spaceflight, and perhaps even find a solution for motion sickness.
A group of 24 active duty service members will get to ride the 50-foot-long machine for 60 minutes, spinning like a dirty sock inside a washing machine at accelerations up to three times the force of gravity to simulate what astronauts experience during spaceflight, NASA
on Wednesday. The torturous ride is meant to help scientists come up with ways to reduce symptoms such as dizziness, nausea, and vertigo once astronauts exit their spacecraft.Sometimes the hardest part about going to space is getting there. Astronauts can experience severe motion sickness during their launch to space, as well as on their way back to Earth.
For the upcoming study, the Kraken will be on a spaceflight-specific setting, as opposed to settings meant for jet pilots, allowing NASA scientists to study whether certain head movements could help ease astronauts’ motion sickness after their flight, according to NASA. “With the ability to move six directions on its axis, the device can simulate complex flight scenarios that are difficult to recreate on Earth, including landing scenarios that could induce vertigo and nausea,” Laura Bollweg, who manages astronaut health research at NASA’s Johnson Space Center in Houston, said in the statement.
The other half of the group will not perform the head movements, but all 24 volunteers will be asked to perform four tasks: testing their balance while standing on foam with eyes open and closed, walking for 33minute walk, and how long it takes for them to finish a standing and walking test that includes stepping over an obstacle.
