cancer probability increased to only 3%? i think they're underestimating...

^ Ya think ?

The estimate is just for zipping there and back; it doesn't include time spent on the Martian surface, which would add to an astronaut's exposure.

Radiation on a Mars trek would be higher than what crew members cocooned inside the International Space Station typically face

The most dangerous flux un this was protons, a chargef particle that is susceptible to the ship having an artificial magnetosphere. NASA signed a deal recently with one of the most advanced high temperature superconducting magnet manufacturers to design, and possibly make, a prototype.

Speed can be handled by a VASIMR or other plasma drive (VASIMR heading to ISS for testing next year), or the proposed FPR fusion drive being tested at NASA this summer. Some of these would cut the trim to ~3 months.

Surely testing VASIMR to the ISS isn't going to show it's justice as it's a short distance compared. Wouldn't they be better off using the technology with another deep space satellite, like device.

I guess the technology is there, it's just cost like most things holding back.

Living on Mars still can't be ruled out just because of this, after all, there's no stopping living under the surface.

Just send a space adapted caterpillar digger :shifty:

I feel they'll solve the problem by 2030. If not, we don't deserve to go.

I think they ought to send a camera as well as some plants first to see if they can start a more suitable atmosphere.

I vote kudzu and Cactus first.

Maybe also send Roaches as well... they say they can live through a nuclear war.

I mean first let us see if we can safely get life to and back from Mars first.

A 200kw testbed just to space qualify it. Other such testbeds sill be the NOFBX monopropellant and its engine, various sensors & cameras etc. Done all the time.

There are several companies working on aspects of the problem, including SpaceX whose mysterious "MCT" (part of its Mars architecture) should be announced within a year. They 're already looking at NASA's Pad 39A (Apollo / shuttle) as a place to launch their super-heavy launcher(s) - able to loft 150-200 tons. Huge SOB. Also prepping to announce a private spaceport in Brownsville, TX, along with a new factory there for their big rockets. Mr. Musk wants to go to Mars.
