Sad news for hopes of future visits to the red planet — anyone who journeys to Mars could come back with their DNA adversely altered, Russian scientists warn. Mars Daily explains:
Future astronauts working on the Red Planet’s surface risk general changes in health at the DNA level because of increased radiation exposure, a prominent Russian academic said on Monday.
“According to our estimates, researchers on the surface of Mars can expect a number of adverse factors, such as cardiac arrhythmia, sensory impairments, changes at the DNA level, and demineralization of bone tissue,” Anatoly Grigoryev, the deputy head of Russia’s Academy of Sciences, told at a presentation at the International Symposium on the results of ground-based experiment Mars-500.
The unique Moscow-based Mars-500 experiment was completed on November 4. It attempted to recreate at least some of the conditions of a flight to the Red Planet by locking six men away in a mock spacecraft.
