Space travel, which does not fall on the agenda of billionaire names, seems to be postponed for a while after the results of this study. NASA has revealed that astronauts’ blood shows signs of various DNA mutations after spaceflights, and therefore their cancer risk should be monitored.
14 ASTRONATERS FOLLOWED FOR 20 YEARS
14 astronauts who took part in space missions at NASA between 1998 and 2001 lasting an average of 12 days participated in the study. It was stated that 85 percent of them were men and six of them took part in their first missions for the space agency.
The researchers collected whole blood samples from the astronauts twice, ten days before spaceflight and on the day of landing, and white blood cells collected only once, three days after landing. These samples were frozen at minus 80 degrees Celsius and remained untouched for 20 years.
IS IT TRANSFERRED TO FUTURE GENERATIONS?
According to the news on NTV; Professor at the Cardiovascular Research Institute in New York. Dr. “Astronauts work in an extreme environment where many factors can lead to somatic mutations, most notably space radiation, which means there is a risk of these mutations developing into clonal hematopoiesis,” said David Goukassian. A somatic mutation is a mutation that occurs after a person is pregnant and in cells other than sperm or egg cells, that is, mutations that cannot be passed on to future generations.
