Space tourists experience some of the same body changes as astronauts who spend months in orbit, according to new studies published Tuesday. Those shifts mostly returned to normal once the amateurs returned to Earth, researchers reported. Research on four space tourists is included in a series of studies on the health effects of space travel, down to the molecular level.
This will allow us to be better prepared when we’re sending humans into space for whatever reason,' said Allen Liu, a mechanical engineering professor at the University of Michigan who was not involved with the research. and others have long studied the toll of space travel on astronauts, including yearlong residents of the International Space Station, but there's been less attention on space tourists. The first tourist visit to the space station was in 2001, and opportunities for private space travel have expanded in recent years.
While in space, the four passengers on the SpaceX flight, dubbed Inspiration4, collected samples of blood, saliva, skin and more. Researchers analyzed the samples and found wide-ranging shifts in cells and changes to the immune system. Most of these shifts stabilized in the months after the four returned home, and the researchers found that the short-term spaceflight didn’t pose significant health risks.
