Manned Mars Missions –“The Cosmic Threat”


What happens to an astronaut’s brain during a mission to Mars? Nothing good. It’s besieged by destructive particles that can forever impair cognition, according to a UC Irvine radiation oncology study. Charles Limoli and colleagues found that exposure to highly energetic charged particles – much like those found in the galactic cosmic rays that bombard astronauts during extended spaceflights – cause significant damage to the central nervous system, resulting in cognitive impairments. “This is not positive news for astronauts deployed on a two- to three-year round trip to Mars,” said Limoli, a professor of radiation oncology in UCI’s School of Medicine.
