NASA says it would take almost a year using conventional rockets to get to Mars. By that time a human body would likely turn to jello due to exposure to space radiation. But the space agency has come up with a solution – in fact two of them.
First they want to build the nuclear rocket (Project Prometheus) which NASA says would cut in half the amount of time it would take to get to the red planet. With nuclear reactors for engines NASA also says they could carry heavier payloads which would make it possible to “mine the sky” for precious minerals.
The other solution to the space radiation problem seems to rely on testing monkeys by exposing them to doses of radiation so NASA can further study the effects on the human body.
