Space Shuttle

everything and love ))

The shuttle has a large payload and it is reusable.

Yes, Mae Jemison encountered prejudice because people believed that a woman couldn't be an astronaut, especially a black woman.

Approximately 153 million miles.

17,500 miles/hour * 24 hours/day = 420,000 miles/day
420,000 miles/day * 365 days/year = 153,300,000 miles/year

Oh, dude, Mae Jemison was just your average astronaut, physician, and engineer who also happened to be the first African American woman to travel in space. No big deal, right? She also served in the Peace Corps and founded a technology research company. Just your typical overachiever, really.

It's called Reentry.

a apace shuttle looks like an air plain with spical sheilds to protect it from the atmespher

It depends on the altitude of the orbit it is in. When the shuttle visits the ISS it is travelling at approximately 17,000 MPH.

Incidentally the shuttle is due to make its last flight later this year (2010)

Yeah, sure whatever ou say...

The Space Shuttle Program was Commissioned by NASA and built by the joint effoerts of United Space Alliance, Thiokol/ Alliant Techsystems, Lockheed Martin, and Boeing Rockwell. The Space Shuttle program has nothing to do with religion and spirituality.

Its a function of your date of birth, your location (Time-Zone), your education and your sex. Just try changing your details.

Inertia can be thought of figuratively as a mass's laziness. Think of when you are lazy. When you're lazy and doing nothing, you tend to stay that way. You continue to do nothing unless prodded to do something. (Perversely, in people, laziness causes idleness and idleness causes laziness.) Well, masses are the same way. When they're inert -- meaning not moving -- they tend to stay that way because of their laziness. That laziness is called inertia. When a huge rocket laden with tons of fuel is sitting on the launch pad, it has tremendous inertia because it is massive. To get that thing moving takes a huge amount of power. But once it's moving, the rocket's inertia, instead of being a handicap, becomes an asset, because any mass, once it's moving, likes to stay moving. Moreover, as the rocket burns off fuel, its mass decreases, so less energy is required to propel it.

I didn't know that it was - but I would imagine they would do so to reduce the weight of the shuttle so it does not re-enter the atmosphere too quickly. If the fuel is something like liquid oxygen it would have no ill effects on the atmosphere.

== They dump fuel to reduce shuttle weight so it can decelerate faster in the Earth's atmosphere. It doesn't slow due to the dumping itself.

astronaut

I don't know who but I think a telescope.

Galileo looked was first to look through the telescope.

she was born in Decatur, Alabama

1963

Yes, she is the youngest of three children.

The solid rocket boosters each consume propellent at a rate of about 11,000 pounds per second. The 3 main engines on the orbiter combined consume about 1000 gallons on liquid hydrogen and liquid oxygen per second, draining the 520,000 gallon external fuel tank in the 8 1/2 minutes of powered flight

Half a million gallons.

They breathe artificial "air" that is almost the same as the air on Earth. It is made up of 20% oxygen and 80% nitrogen similar to the air we breathe and it is at a pressure of 14.7psi which is the same as the atmospheric pressure on earth.

From an original estimate of about $400 million, by the time of launch it had cost $2.2 billion and by today has probably cost twice that amount.
