Will Mars Scramble Your Brain? Scientists Debate Radiation Study

Could a trip to Mars addle your brains? Some scientists say it might, based on a study of high-energy radiation’s effects on mouse neurons. But an advocate for Red Planet missions says the study overstates the effects.

The report, published Friday in the open-access journal Science Advances, found that mice who were exposed to radiation similar to galactic cosmic rays showed degradations in their brain cells, and didn’t do as well on cognitive tasks.

“This is surprising, and it suggests that NASA has a new complication to consider when they send astronauts into deep space,” senior study author Charles Limoli, a professor of radiation oncology at the University of California at Irvine’s School of Medicine, told NBC News.

78,000 apply to leave Earth forever to live on Mars

Huge numbers of people on Earth are keen to leave the planet forever and seek a new life homesteading on Mars.
About 78,000 people have applied to become Red Planet colonists with the nonprofit organization Mars One since its application process opened on April 22, officials announced Tuesday. Mars One aims to land four people on the Red Planet in 2023 as the vanguard of a permanent colony, with more astronauts arriving every two years thereafter.
“With 78,000 applications in two weeks, this is turning out to be the most desired job in history,” Mars One Chief Executive Officer and co-founder Bas Lansdorp said in a statement. “These numbers put us right on track for our goal of half a million applicants.”

Rover Curiosity aims to unlock the biggest mysteries of Mars

Mars, our next-door neighbor in the solar system, hasn’t given up many of its secrets yet. But when NASA’s newest Mars rover, Curiosity, lands on the Red Planet next week, scientists hope to unlock a few more.
The centerpiece of the Mars Science Laboratory mission, the Curiosity rover comes packed with a slew of instruments to study not only today’s Martian surface, but also the surface of the past.
