The problem of energy can be solved with onboard fusion reactor. http://youtu.be/ro5-QYqqxzM

@ HJS11211 - When you only listen to propaganda from the regime or its minions in the media you don't get the full or true story on what you hear and you miss many other stories that exist.

One of many comments and articles:

what?

It's really a problem of energy. With sufficient energy, you could accelerate at sufficient velocity to create the effect of standard gravity. The ship would reach relativistic velocities, reducing the perceived travel time. At the halfway point, the ship would spin around and start decelerating at one gravity. To do this you need a lot of energy! That same energy source could also address the problems of food and water on board the ship.

That same energy source would also radically reshape life here on earth solving most of our existing problems, and given human nature, creating a whole bunch of new ones.

No, Paul, We want those physicists back on Wall Street powering up the next flash crash. sarcasm.

Even as the President was taking NASA apart and leaving it without manned vehicles for the 1st time in 50 years, he claimed that Islam had a great role to play in NASA's success; exactly what role did Islam play in American space exploration in the past 50 years?

Paul, most plans include a spinning ring to create false gravity. Same effect on the body as having gravity.

Why?

These projects for me are all about keeping astrophysicists employed. As bright as these people are, why not have them put more concentration on fixing the mess that humans have made of earth - particularly since the industrial revolution.

Do we really need to chase the improbably to realize improvements on earth?

What might Voyager be able to tell us about what's beyond the heliosphere?

What is the speed and travel time that you expect to get with the technologies you have on your drawing board right now?

Space. Where hearing 17,000 miles an hour makes you say: 'Is that all?'

have there been any real advances in improving the bodies ability to withstand extended time without gravity?
