Why did the space shuttle have engines?
The engines were used for propulsion during the entirety of the spacecraft’s ascent, with additional thrust being provided by two solid rocket boosters and the orbiter’s two AJ10 orbital maneuvering system engines. On Space Launch System flights, the engines will be expendable.
Why was the space shuttle inefficient?
Criticism of the Space Shuttle program stemmed from claims that NASA’s Shuttle program failed to achieve its promised cost and utility goals, as well as design, cost, management, and safety issues. Fundamentally, it failed in the goal of reducing the cost of space access.
How many main engines does the shuttle have?
three Space Shuttle Main Engines
The three Space Shuttle Main Engines, in conjunction with the Solid Rocket Boosters, provide the thrust to lift the Orbiter off the ground for the initial ascent. The main engines continue to operate for 8.5 minutes after launch, the duration of the Shuttle’s powered flight.
Why is a space shuttle better than a spacecraft?
The Space Shuttle was only designed for low Earth orbit. It could not go into high Earth orbit nor escape Earth orbit to fly in deep space. A “spacecraft” is any human-made object launched into space, manned or unmanned, satellite or spaceship.
What engines did the space shuttle use?
The RS-25 is a staged-combustion engine cycle powered by liquid hydrogen and liquid oxygen, making it one of highest performing engines the nation has ever produced. The SSME engines on the shuttle typically operated at 491,000 pounds vacuum thrust (104.5-percent of rated power level).
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.
How complicated was the space shuttle?
The US space shuttle is the most complex and costly flying machine ever built. The shuttle could fly at speeds of 17,500 miles (28,160 kilometers) per hour and was designed to maneuver in low Earth orbit at 100 to 400 miles (160-640 kilometers) high. …
Did space shuttle have engines?
Each Space Shuttle consisted of three Space Shuttle Main Engines. The three SSME’s, in conjunction with the Solid Rocket Boosters, provided thrust to lift the Orbiter off the ground for the initial ascent. The main engines continued to operate for 8.5 minutes after launch, the duration of the Shuttle’s powered flight.
Does space shuttle use engines to land?
The Space Shuttle flies as a glider during reentry and landing. During ascent, thrust is provided by the three Space Shuttle Main Engines (SSME’s) at the base of the orbiter and the two Solid Rocket Boosters (SRB’s) that are joined to the orange External Fuel Tank (ET).
Why did NASA abandon the space shuttle?
While reentering Earth’s atmosphere, Columbia broke apart, killing the entire crew. All of these factors — high costs, slow turnaround, few customers, and a vehicle (and agency) that had major safety problems — combined to make the Bush administration realize it was time for the Space Shuttle Program to retire.
How fast does a space shuttle go to leave Earth?
A spacecraft leaving the surface of Earth, for example, needs to be going about 11 kilometers (7 miles) per second, or over 40,000 kilometers per hour (25,000 miles per hour), to enter orbit. Achieving escape velocity is one of the biggest challenges facing space travel.
How many engines does a Space Shuttle have?
Space Shuttle Main Engines The three Space Shuttle Main Engines, in conjunction with the Solid Rocket Boosters, provide the thrust to lift the Orbiter off the ground for the initial ascent. The main engines continue to operate for 8.5 minutes after launch, the duration of the Shuttle’s powered flight.
How do space shuttles work?
The engines’ exhaust is primarily water vapor as the hydrogen and oxygen combine. As they push the Shuttle toward orbit, the engines consume liquid fuel at a rate that would drain an average family swimming pool in under 25 seconds generating over 37 million horsepower.
How many pounds of thrust does a space shuttle produce?
They create a combined maximum thrust of more than 1.2 million pounds. As the Shuttle accelerates, the main engines burn a half-million gallons of liquid propellant provided by the large, orange external fuel tank.
How fast do space shuttles launch?
After the solid rockets are jettisoned, the main engines provide thrust which accelerates the Shuttle from 4,828 kilometers per hour (3,000 mph) to over 27,358 kilometers per hour (17,000 mph) in just six minutes to reach orbit. They create a combined maximum thrust of more than 1.2 million pounds.
