How are the space shuttle engines ignited?
In a liquid oxygen-liquid hydrogen engine, such as the space shuttle main engine, they are actually ignited by a spark igniter. They are located in the augmented spark igniter chamber, and they actually ignite the fuel.
Who makes the rs25 rocket engine?
Aerojet Rocketdyne
Designed and manufactured in the United States by Rocketdyne (later known as Pratt & Whitney Rocketdyne and Aerojet Rocketdyne), the RS-25 burns cryogenic liquid hydrogen and liquid oxygen propellants, with each engine producing 1,859 kN (418,000 lbf) of thrust at liftoff.
How big is an rs25 engine?
Length: 168 in. Diameter: 96 in. Weight: 7,775 lb.
Why are the space shuttle engines angle?
They are angled upwards because the shuttle and its launch vehicle are inherently unbalanced. When the entire thing is assembled on the pad, the main engines and SRBs impart opposite torques on the orbiter, and therefore it is stable during launch.
What engines were on the space shuttle?
Space Shuttle components include the Orbiter Vehicle (OV) with three clustered Rocketdyne RS-25 main engines, a pair of recoverable solid rocket boosters (SRBs), and the expendable external tank (ET) containing liquid hydrogen and liquid oxygen.
Why is SLS using RS-25?
www.nasa.gov Two additional RS-25 ground test engines are being used at NASA’s Stennis Space Center to test fire updates to the engine, adapt it to SLS performance requirements and operating environments, certify new controllers, and support development of future engine components.

Does Space Shuttle glide to earth?
The Space Shuttle flies as a glider during reentry and landing. The shuttle was designed with a low L/D ratio (~ 1) because during the descent the spacecraft must be slowed from about 17,300 mph to about 250 mph at landing.
Does the Space Shuttle use engines when landing?
The Space Shuttle is a Lifting Body Approximately 24,000 feet above the Mojave Desert a high-tech glider was released from its flying perch. It glided effortlessly without engine power to a smooth landing on the desert floor.
