oooooh!!!! i must have stepped on some long toes!!!!!
come on guys,open your eyes!
let's keep the bad rep coming!!!!i don't care
Funny pic Dark Star, the UFO peeps will love it !
Here's how you go from 13,000mph to 200mph & land in one piece

I agree with DrFever...an amazing accomplishment! I understand the starving people, I understand the financial abyss in front of the USA, I understand the negatives...but we are currently SURROUNDED by knowledge, inventions, assets, life-saving and life improving technologies spawned from the Mercury and Apollo eras and we are , as humanity, better off for it. Yes, as a country, we POUR $$$ down bottomless holes and politicians pockets, and that infuriates me, at least, HERE, we get some bang for our buck. Not sayin' NASA isn't political or bottomless...but they hammered this one and we will benefit therefrom. This stuff jazzes me as much as the pictures of Dooby Ducks buds!

Dread, innovation can only help everyone involved. I am not rich by any means and grew up as poor as most in America can grow up. Not Ethiopia levels, but having to eat mac and cheese or beans and if your lucky maybe some pieces of franks mixed it to a portion 1/2 or 1/3 the size of what would have been satisfying? Resenting all who had it better? been there done that! but in the grand scheme of things, NASA budget is shit. If you want to feed the world, go after the military budget, or the drug war budget, or the deep pockets of the worlds elite. NASA's budget needs to be many times the meager 15 or so billion it is to be effective and if funded at appollo era levels they would have like 250 billion. We need the income space can generate, many times what the world generates now. Let's innovate and lets settle and mine space already!

Eric and others echoing the sentiment I couldn't agree more. Unfortunately you are going against a force stronger then gravity...hypocrisy.
Your trying to discourse with some who 'burned their draft card, but kept the food stamps'.
When you point out a hypocrisy it's like trying to teach a pig to sing. All you do is waste your time and you wind up with a pissed of pig.
thanks eric for the great post!

'Warp drive' may be more feasible than thought, scientists say
Published September 17, 2012
Space.com
A warp drive to achieve faster-than-light travel — a concept popularized in television's Star Trek — may not be as unrealistic as once thought, scientists say.
A warp drive would manipulate space-time itself to move a starship, taking advantage of a loophole in the laws of physics that prevent anything from moving faster than light. A concept for a real-life warp drive was suggested in 1994 by Mexican physicist Miguel Alcubierre, however subsequent calculations found that such a device would require prohibitive amounts of energy.
Now physicists say that adjustments can be made to the proposed warp drive that would enable it to run on significantly less energy, potentially brining the idea back from the realm of science fiction into science.
"There is hope," Harold "Sonny" White of NASA's Johnson Space Center said here Friday (Sept. 14) at the 100 Year Starship Symposium, a meeting to discuss the challenges of interstellar spaceflight.
Warping space-time
An Alcubierre warp drive would involve a football-shape spacecraft attached to a large ring encircling it. This ring, potentially made of exotic matter, would cause space-time to warp around the starship, creating a region of contracted space in front of it and expanded space behind. [Star Trek's Warp Drive: Are We There Yet? | Video]
Meanwhile, the starship itself would stay inside a bubble of flat space-time that wasn't being warped at all.
"Everything within space is restricted by the speed of light," explained Richard Obousy, president of Icarus Interstellar, a non-profit group of scientists and engineers devoted to pursuing interstellar spaceflight. "But the really cool thing is space-time, the fabric of space, is not limited by the speed of light."
With this concept, the spacecraft would be able to achieve an effective speed of about 10 times the speed of light, all without breaking the cosmic speed limit.
The only problem is, previous studies estimated the warp drive would require a minimum amount of energy about equal to the mass-energy of the planet Jupiter.
But recently White calculated what would happen if the shape of the ring encircling the spacecraft was adjusted into more of a rounded donut, as opposed to a flat ring. He found in that case, the warp drive could be powered by a mass about the size of a spacecraft like the Voyager 1 probe NASA launched in 1977.
Furthermore, if the intensity of the space warps can be oscillated over time, the energy required is reduced even more, White found.
"The findings I presented today change it from impractical to plausible and worth further investigation," White told SPACE.com. "The additional energy reduction realized by oscillating the bubble intensity is an interesting conjecture that we will enjoy looking at in the lab."
Laboratory tests
White and his colleagues have begun experimenting with a mini version of the warp drive in their laboratory.
They set up what they call the White-Juday Warp Field Interferometer at the Johnson Space Center, essentially creating a laser interferometer that instigates micro versions of space-time warps.
"We're trying to see if we can generate a very tiny instance of this in a tabletop experiment, to try to perturb space-time by one part in 10 million," White said.
He called the project a "humble experiment" compared to what would be needed for a real warp drive, but said it represents a promising first step.
And other scientists stressed that even outlandish-sounding ideas, such as the warp drive, need to be considered if humanity is serious about traveling to other stars.
"If we're ever going to become a true spacefaring civilization, we're going to have to think outside the box a little bit, were going to have to be a little bit audacious," Obousy said.
