Two shuttle teams.

When the space shuttle was approved in 1972, NASA officials predicted that they would launch one every week or two.

Then NASA had two large and image damaging space shuttle accidents the Challenger disaster of 1986, followed by the disintegration of the Columbia over Texas in 2003.

Liquid hydrogen or slush hydrogen may be used, as in the Space Shuttle.

STS 1 was the first orbital flight of NASA's Space Shuttle program.

We've done two so far.

I lost two of my friends, we're 25 miles from Harry's shuttle.

In fact the space shuttle gets up only a couple of hundred miles above the surface of the earth.

So the space shuttle, if I was to draw it to scale, would probably be right about there.

Spitzer was the only one of the Great Observatories not launched by the Space Shuttle.

From bicycles to jet packs, from looking up at the stars to entering outer space in the shuttle, our capacity to acquire knowledge and imagination to achieve impossible goals appears to be limitless.

But as that space shuttle returns to Earth, and as the astronauts enter the Earth's gravitational field, they begin to see the effects of gravity.

Some people tell us about the origin of the universe as if they had just flown back from there on a space shuttle.

What the hero did to the girl is mathematically the same as running her over with a space shuttle at maximum speed.

Nor has the US space shuttle accomplished its goals.

It is a participant in the International Space Station the Japanese Experiment Module (Kibo) was added to the station during Space Shuttle assembly flights in 2008.

But as that space shuttle returns to Earth, and as the astronauts enter the Earth's gravitational field, they begin to see the effects of gravity.

We've done two so far. We'll be announcing two more on the Soyuz to go up to the space station for 20 million dollars.

STS 31 was the thirty fifth mission of the American Space Shuttle program, which launched the Hubble Space Telescope astronomical observatory into Earth orbit.

So what you do is you throw in the opposite direction, and that'll allow the astronaut to accelerate towards the space shuttle, and and hopefully, grab onto something.

And today, there's only three vehicles the U.S. shuttle, the Russian Soyuz and the Chinese vehicle that gets you there.

Remember, it's not the speed that causes the damage because the astronauts survived Apollo 10, it's the acceleration or sudden stop that causes our internal organs to crash into the front of our bodies the way we move forward in a bus when the driver slams on the brakes.

Hubble was originally intended to be retrieved and returned to Earth by the Space Shuttle, but the retrieval plan was later abandoned.

This eliminated the possibility of improvement or repair by the space shuttle but put the observatory above the Earth's radiation belts for most of its orbit.

But the space shuttle has proven far more difficult and costly to operate than anticipated, flying only four times per year on average.

But things have slowed down dramatically since then, and NASA has been trying since early November to get its latest shuttle ready for launch.

Von Braun predicted that the US would need to launch 364 space shuttles in less than one year to prepare for the first lunar voyage.

For example, the Space Shuttle flight computers initially used core memory, which preserved the contents of memory even through the Challenger's disintegration and subsequent plunge into the sea in 1986.

PEM fuel cells were used in the NASA Gemini series of spacecraft, but they were replaced by Alkaline fuel cells in the Apollo program and in the Space shuttle.

They were first recorded on October 21, 1989, on a monochrome video of a thunderstorm on the horizon taken from the Space Shuttle as it passed over Australia.

P W Rocketdyne engines powered the Space Shuttle, and the company also supplies booster engines for Delta II rockets and boosters and upper stage engines for Atlas III and V and Delta IV rockets.

It's not a gravity free environment, it's just that the astronauts and space shuttle and everything else that's in the space shuttle is all falling but it's moving fast enough that it never hits the earth.

Once you're in orbit, you are two thirds of the way, energetically, to anywhere the moon, to Mars. And today, there's only three vehicles the U.S. shuttle, the Russian Soyuz and the Chinese vehicle that gets you there.
