Space Shuttle

5 Space Shuttle orbiters have been built. 3 remain in service.

The reason the Space Shuttle (or any other orbiting object) stays in orbit is a combination of centrifugal force and falling. Basically, the object is constantly falling due to gravity. However, it's also traveling around the planet and the centrifugal force of that travel is equal to the gravity causing it to fall. This is why inside the craft is weightless, gravity is negated by the force.

This is also why some objects fall, their orbit and speed are not matched 100% to the force of gravity, so they slowly fall into the earth. This is also how shuttles and other ships come back to earth, they slow their orbit and gravity takes over!

In my opinion the Challenger space shuttle wasn't ready to be launched in the first place. But I'm truly sorry, no one really knows exactly why for sure this tragedy happened. Only God knows for sure.

i don't know because they want 2 :p << Huh?

President Bush canceled it in 2004

See the following article:

There are mainly two types of model rockets: pre-assembled or ready-to-fly rockets that require minimal or no construction, and model rocket kits that require assembly. Model rocket kits can be further categorized based on their complexity and size, ranging from beginner kits to advanced high-power rockets.

It typically takes a few hours for the space shuttle to cool down after reentry and landing. The shuttle's thermal protection system keeps it insulated from the intense heat of reentry, and once on the ground, the heat dissipates gradually. Cooling fans and thermal protection blankets help speed up the process.

not sure there are two different scales that i know of GS-12 can earn up to $65,000+ a year.

Gs-13 $96,700+ a year

depending on experience and commitment to the job and how long you have been doing it you can be earning up to $114, 000+ year.

Starter astronaughts earn $175.00 a day. Not to sure about this but i got this off the internet from other forums so just look around.

Good Luck :)

The Space Shuttle accelerates greatly after lift-off, - to prevent any inadvertent damage to the nosecone that may occur due to this excessive acceleration, (bird-strikes, small insects, meteorites etc:) The craft is tilted so that the the main fuel tank will absorb any instances of impact. Hence the reason the Shuttle orbits in a rearwards manner.

The 11 May 2009 space mission was the launch of the Space Shuttle Atlantis on the STS-125 mission to repair and upgrade the Hubble Space Telescope. The mission involved five spacewalks to install new instruments and make repairs to extend the telescope's operational lifespan.

To make a space rocket, you need to design a rocket system that includes a propulsion system, payload section, guidance system, and structural components. The rocket will require fuel, such as liquid or solid propellants, and will need to be tested extensively to ensure safety and functionality before launch. Additionally, you'll need to secure the necessary permits and permissions to launch the rocket into space.

Thermosphere is the atmosphere's outermost layer with a very thin air and no definite outer limit. The reason why a space shuttle gets through it is because shuttle orbiters used ceramic tiles and heat protection.

The space shuttle propulsion system isn't powerful enough to get to the moon let alone Saturn.

The space shuttle gets up to a speed of about 4 miles per second maximum which is enough to then coast in earth orbit for many days but not enough to get more than a few hundred miles up. That's why it is so easy to see from the ground - it's not that far up.

Using existing technology Nasa has estimated a manned trip to mars would take about 3 months. Saturn at its closest would be about 10 times farther than mars. So to get there in less than 30 months would require an even more powerful rocket than planned for mars.

Design and building of the US space shuttle began in the 1970's, and after many delays the first flight was in 1981.

The universe can be explored by astronomical instruments called telescopes, and by space probes sent from earth to other planets. When using telescopes astronomers try to look at the energy being produced by the universe not just in the visible part of the spectrum (where our eyes can see) but at the whole range of electromagnetic radiation. We thus have radio telescopes, infrared telescopes, X-ray telescopes and even some telescopes that are buried deep underground looking for neutrinos. Most of the telescopes are set in mountains for they can rich more.

The space shuttle that disintegrated upon re-entering Earth's atmosphere on February 1, 2003, was the Space Shuttle Columbia. The disintegration occurred due to damage sustained to its thermal protection system during launch, leading to the loss of all seven crew members on board.

Each of the space shuttles were named after famous ships. Enterprise was the first shuttle to be named although it never actually saw service. The selection of it's name was also part of a competition, the result saw it named after the Star Trek craft as well as other bearers of the name.

Spaceships take off from Earth or other celestial bodies by using rocket propulsion. Rockets generate thrust by expelling high-speed exhaust gases, pushing the spaceship upwards against gravity. The exhaust gases are usually produced by burning a fuel and an oxidizer in a controlled combustion process.

Dr. Mae C. Jemison worked at NASA from 1987 to 1993. She made history in 1992 as the first African American woman to travel in space aboard the Space Shuttle Endeavour.

The external tank for the 1st shuttle mission was white. It was painted white for the historic first launch. All other missions have used the natural color of the external tank's foam to save the cost and weight that the paint added.

Zirconium, zirconium alloys and some zirconium ceramics (ZrO2, Zr N, ZrB2) are very thermoresistant, has good mechanical properties, great hardness, etc.; these properties are very important for some external components of space aircrafts.

The External Tank (ET) of the Space Transportation System is not reusable. It is the only major component that is not designed to be recovered and reused. The ET provides fuel to the Space Shuttle's main engines during launch and is jettisoned once its fuel is depleted.

Six air-worthy shuttles have been built; the first orbiter, Enterprise, was not built for space flight, and was used only for testing purposes. Five space-worthy orbiters were built: Columbia, Challenger, Discovery, Atlantis, and Endeavour. Challengerdisintegrated 73 seconds after launch in 1986, and Endeavourwas built as a replacement. Columbia broke apart during re-entry in 2003.

When the Columbia space shuttle was launched in 1981, it was its first flight. The commander on the flight was John Young. This space shuttle completed 27 missions before the disaster that happened in February of 2003 in which it disintegrated.

Space Shuttle Discovery, September 29, 1988.

I'm not sure but i think the answer is
