Dallas – Space tourists experience the same physical changes as astronauts who spend months in orbitAccording to new research published Tuesday.
Those changes mostly returned to normal once tourists returned to the city. TierraThe researchers said.
Research on four space tourists is included in a series of studies on the health effects of space travel at the molecular level. The researchers said The results help us get a clearer idea of how people who haven’t trained for years as astronauts adapt to weightlessness and space radiation.
“This will allow us to be better prepared when sending humans into space for any reason.”said Alan Liu, a professor of mechanical engineering at the University of Michigan who was not involved in the research.
The NASA and other agencies have long studied the effects of spaceflight on astronauts, including those living in space International Space Station People who spend a long time in orbit, but less attention is paid to space tourists. The first tourist trip to the space station took place in 2001, and private space travel opportunities have expanded in recent years.
A three-day charter flight in 2021 gave researchers a chance to study how quickly the body reacts and adapts to space travel. said Susan Bailey, a radiation expert at Colorado State University who participated in the research.
During their stay in space, there were four passengers on board SpaceXNamed Inspiration 4, it collected samples of blood, saliva and skin. The researchers analyzed the samples and found widespread changes in cells and the immune system. Most of these changes were confirmed in the months after the four returned home, the researchers concluded Short-duration space flights pose no significant health risks.
“This is the first time we’ve done a cell-by-cell examination of a crew in space.” Chris Mason, a researcher at Weill Cornell Medicine and co-author of the study, said.
The studies, published Tuesday in the journal Nature and now part of the database, include the impact of spaceflight on the skin, kidneys and brain. Immune system. The results could help researchers find ways to counteract the negative effects of space travel, said Afshin Beheshti, a researcher at the Blue Marble Space Institute of Science who participated in the research.
