Space Shuttle

The Space Shuttles are reusable spacecraft with wings for controlled descent into the atmosphere. They are designed to transport astronauts between earth and an orbiting space station and to deploy and retrieve satellites. Atlantis, Discovery, and Endeavour are the three Space Shuttles in operation today.

Which fuel is used in spacecraft?

Spacecraft use either liquid or solid fuel. All rockets operate on a combination of a fuel and an oxidizer to help the fuel burn.

Russian rockets use liquid fuel, a combination of Liquid Oxygen (also called LOX) and a highly refined form of kerosene (also called RP-1). American and other rockets and spacecraft use a combination of liquid fuel as above and solid fuel.

Solid rocket fuel is composed of fuel like charcoal, metals such as alumnium or zinc, or even sugar along with potassium nitrate as an oxidizer all combined in a binder such as rubber or forms of plastics. An additive such as sulfur can also be added to help stabilize the burn.

Once in orbit, hypergolic fuels are used. 2 chemicals are used which, when combined explode. This allows rockets to be used without any ignition source.

Why did the space shuttle stop going to the space?

The space shuttles have been retired, because NASA does not have enough missions that would require a shuttle. (We might still use them to bring supplies to the international space station, but alternatives are available.) In the current political situation, of massively high national debt and bitter conflict between the Democratic Party and the Republican Party about how to deal with this debt, it is not possible to fund expensive programs of space exploration.

How many stages in a rocket engine?

It depends. Some rocket engines have a single stage, some have 3 or more.

Staging allows for the overall weight of the vehicle to be reduced by dropping off parts of the rocket and continuing on with smaller rocket engines and less fuel.

How large is the Virgin Space Shuttle?

It holds 6 passengersand 2 pilots. It h

as a wingspan of 27ft, is 60ft long, and is 15ftall.

Why do space shuttles heat up when they re-enter into the earths atmosphere?

When the shuttle goes from the vacuum of space and enters the earths atmosphere, it heats up because of simple friction. The friction is from the shuttle going so fast and hitting the atmosphere. Same reason you sometimes see meteor showers.

What was the highest a space shuttle ever went?

600km circular orbit during hubble telescope missions

How many space shuttle orbiters were made?

Six were made, but only five ever went into space.

Is space shuttle an airplane?

no

an airplane cant go into space whereas a space shuttle can. they're made differently

What was the name of the first space shuttle to ever go into outer space?

The Columbia it was launched by NASA on April 12, 1981. It became the first shuttle to orbit (circle around) Earth.

What space shuttle launched in 1972 is still in orbit?

The first space shuttle was launch in 1981. Space shuttle missions do not stay in orbit, they are designed to return to Earth after missions generally lasting 1-2 weeks.

What are two careers in space exploration?

There are many many careers in space exploration. Astronaut usually comes to mind first but there are many engineering and science careers on the ground as well.

How many space shuttle flights were there?

135, with 133 successes and two failures (Challenger and Columbia)

How long does it take a rocket to go to space?

The space shuttle went from sea level to orbit in about 8 minutes

How do astronauts prepare for a space launch?

Astronaut training takes years before an individual is selected for a particular mission.

Astronauts prepare for that launch day with a series of medical tests to ensure they are healthy for the launch and are expected to stay healthy through the mission. They then begin to acclimate themselves to a new time schedule based on launch time. They spend the final day or two at the Kennedy Space Center in simple crew quarters and have a meal together before suiting up several hours before launch.

How strong is a space shuttle?

Strong enough to pull 7,000,000 pounds of thrust at launch and survive +3,000 degrees F during reentry. Stronger than your moms pan that's for sure.

How long before docking to the iss does the space shuttle have to start slowing down to make a safe docking?

During launch the space shuttle speeds up to 17500 MPH. In orbit the space station is going about the same speed. So the shuttle does not have to slow down much. At docking the relative speed of the ISS and shuttle is about 1-2 inchs per second.

Why is oxygen needed by rockets and how does it get it?

The first part is simple, you need three things for a fire:

Heat

fuel

Oxygen

You get liquid oxygen that is mixed in with the just fuel before it ignites.
