By a News Reporter-Staff News Editor at Defense & Aerospace Week -- Researchers detail new data in Aeronautics and Astronautics. According to news reporting originating from Houston, Texas, by VerticalNews correspondents, research stated, "Preliminary results of an ongoing study examining the effects of space flight on astronauts' motion perception induced by independent tilt and translation motions are presented. This experiment used a sled and a variable radius centrifuge that translated the subjects forward-backward or laterally, and simultaneously tilted them in pitch or roll, respectively."
Our news editors obtained a quote from the research from National Aeronautics and Space Administration, "Tests were performed on the ground prior to and immediately after landing. The astronauts were asked to report about their perceived motion in response to different combinations of body tilt and translation in darkness. Their ability to manually control their own orientation was also evaluated using a joystick with which they nulled out the perceived tilt while the sled and centrifuge were in motion. Preliminary results confirm that the magnitude of perceived tilt increased during static tilt in roll after space flight. A deterioration in the crewmember to control tilt using non-visual inertial cues was also observed post-flight."
According to the news editors, the research concluded: "However, the use of a tactile prosthesis indicating the direction of down on the subject's trunk improved manual control performance both before and after space flight."
