(Newser) – One of the bigger sticking points in the quest to send humans to Mars has been the potentially deadly radiation levels they would experience. But new information gathered by the Curiosity rover shows that radiation levels on Mars are much milder than feared—about the same as those in low Earth orbit, which is where the International Space Station is located, reports Space. "Absolutely, astronauts can live in this environment," said one Curiosity researcher.

Scientists had worried the planet could have very high radiation levels because Mars lacks a protective magnetic field and possesses an atmosphere that's only 1% as thick as our own. But don't book your space flight just yet: The journey also includes the voyage there and back, and Curiosity experienced radiation levels twice as high as those on Mars' surface during its nine-month trek. Researchers still need to calculate how much radiation an astronaut would be exposed to round-trip before they know whether it's feasible.

There are several people that I know that should be sent to Mars and I would LOVE to be the person to send them there!!!!!! They could be "test subjects" to see how high the radiation level is!!!

It's the Van Allen radiation belt you have to worry getting them past before you can start to worry about Mars.

You know what could really handle the radiation well? The dozens of robot probes we could send to Mars for the same cost as one astronaut.
