What are the two parts parts that can be reused on a space shuttle?

The two white SRBS and the orbiter itself.


What are space shuttles designed for?

The space shuttle is a space vehicle designed to carry five to seven crew members into space. It is made of four components namely, external tank, two solid rocket boosters (SRBs) and one orbiter.The orbiter is reuseable as well as the SRBs. The external tank is lost in space.


Which rocket is used to launch the space shuttle?

The space shuttle was launched using the Space Shuttle Main Engines (SSME) and Solid Rocket Boosters (SRBs) attached to the external fuel tank. The SSMEs provided thrust during liftoff, while the SRBs provided additional thrust for the initial stages of flight before falling away.


How big are rocket boosters?

NASA SRBs(solid rocket booster), have an inert wieght of 190,000 pounds. When filled,they wiegh about 100,100,000 pounds.


Why do the SRB's drop off the shuttle?

The Solid Rocket Boosters (SRBs) drop off the space shuttle to reduce weight and allow the shuttle to continue its journey using its main engines. Once the SRBs have burned out their fuel, they are jettisoned to prevent excess weight and drag during ascent.


What part of the shuttle is reused?

The orbiter, the airplane looking part, and the solid rocket boosters are reused. However, the SRBs (solid rocket boosters) have to be completely dismantled and almost totally rebuilt.


Does the space shuttle use the liquid or solid?

The SRBs (Solid Rocket Boosters) use solid fuel. The 3 main engines and the OMS (Orbital Maneuvering System) use liquid fuel stored in the External Tank.


How does the rocket get the abiliti stopstart engine?

For liquid fuel rockets, it is sometimes as easy as turning off a switch. For solid fuel rockets (like the SRBs on the Space Shuttle) there is no way at all to stop the engines; they quit when the fuel is all burned. That was the problem with the Challenger.


What happens to the rocket when it breaks away from the shuttle?

When the rocket breaks away from the shuttle, it continues to propel the payload (such as a satellite or spacecraft) further into space. Once it has completed its job of delivering the payload to its desired orbit, the rocket will either stay in space as debris or be deliberately moved to a safe disposal orbit.


What part of the spaceship falls off first?

Typically, the boosters or stages of a spaceship detach first once their fuel is depleted. This allows the remaining part of the spacecraft to continue its journey with lighter weight and improved efficiency.


Are the parts of a space shuttle reused?

Yes and no. The SRBs (solid rocket boosters) and EFT (external fuel tank) are jettisoned on takeoff. The orbiter (the part that lands) is reused, though several components are replaced periodically, such as the heat shield tiles, thruster assemblies, and computer components.


Are there any reuseable spacecraft?

The Space Shuttle is pretty much reusable. The orbiter is, and the Solid Rocket Boosters were designed to be salvaged and remanufactured, although I'm not sure that any SRBs have ever flown again. The SpaceShipOne rocket technically reached space, (but not orbit) and is completely reusable, and SpaceShipTwo will be completely reusable.
