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.
Could we “terraform” Mars—that is, transform its frozen, thin-aired surface into something more friendly and Earthlike? Should we? The first question has a clear answer: Yes, we probably could. Spacecraft, including the ones now exploring Mars, have found evidence that it was warm in its youth, with rivers draining into vast seas. And right here [...]
For nearly three decades (since 1981), the Space Shuttle was an iconic symbol of the American space program and the country’s primary way of reaching space. Now as the National Aeronautics and Space Administration is working on its replacement, it’s putting the famous spacecraft up for sale.
NASA in December 2008 first offered the Shuttles [...]

It flew faster and higher than any machine in history and was the was the ultimate boy’s toy, but at $42 million (£25.8 m) it was beyond most budgets. But now the price of Nasa’s soon-to-be redundant space shuttles has [...]

Still hoping for that Jetsons future?
Ruh-roh, as the Jetsons’ dog, Astro, might put it.
Just six years ago, President Bush laid out a vision of space exploration that harked back to NASA’s halcyon days built on astronauts as explorers. Bush wanted to sling them from low Earth orbit to a base on the moon and then, [...]

This year begins a new decade, but it also will see the end of the United States’ trailblazing approach to manned spaceflight: the space shuttle program.
“In just five more flights, a chapter of history will be forever closed,” says Mike Mullane, a three-time NASA space shuttle astronaut and author of Riding Rockets. “It will be [...]
