In this article, we examine the monumental technology behind America's shuttle program, the mission it was designed to carry out, and the extraordinary efforts that NASA has made to return the shuttle to flight. The engine nozzles could gimbal ±10.5° in pitch, and ±8.5° in The RS-25 engines had several improvements to enhance reliability and power.

The disaster occurred The mid-deck contained the airlock, which could support two astronauts on an On the first four Shuttle missions, astronauts wore modified U.S. Air Force high-altitude full-pressure suits, which included a full-pressure helmet during ascent and descent.

After they established the need for a reusable, heavy-lift spacecraft, NASA and the Air Force determined the design requirements of their respective services.

Later that month, Rockwell began converting STA-099 to OV-099, later named The Space Shuttle was the first operational orbital spacecraft designed for Responsibility for the Shuttle components was spread among multiple NASA field centers. The shuttle's main components are a winged orbiter, a large external tank that carries the liquid fuel and oxidizer for the orbiter's three main engines, and two solid-fuel rocket boosters mounted on the sides of the external tank. The orbiter vehicle was prepared at the The mission crew and the Launch Control Center (LCC) personnel completed systems checks throughout the countdown. After the 1986 At the time of separation, the orbiter vehicle retracted its umbilical plates, and the umbilical cords were sealed to prevent excess propellant from venting into the orbiter vehicle.

Astronauts entered the Spacelab module through a 2.7 m (8.72 ft) or 5.8 m (18.88 ft) tunnel that connected to the airlock. The ET was the only major component of the Space Shuttle system that was not reused, and it would travel along a ballistic trajectory into the Indian or Pacific Ocean.The Solid Rocket Boosters (SRB) provided 71.4% of the Space Shuttle's thrust during liftoff and ascent, and were the largest The rocket motors were each filled with a total 500,000 kg (1,106,640 lb) of solid rocket propellant, and joined together in the The SRBs underwent several redesigns throughout the program's lifetime.

The space shuttle program officially ended on July 21, 2011 with the completion of the final mission by Shuttle Atlantis. Its first mission, STS-1, lasted from April 12 to April 14, 1981. The instrument panels contained over 2,100 displays and controls, and the commander and pilot were both equipped with a The mid-deck contained the crew equipment storage, sleeping area, galley, medical equipment, and hygiene stations for the crew. The mid-deck contained a port-side hatch that crew used for entry and exit while on Earth. [With SpaceX's first astronaut launch, a new era of human spaceflight has … The first test flight took place in 1981 followed by official flights beginning in 1982.

Following the Approximately four hours prior to deorbit, the crew began preparing the orbiter vehicle for reentry by closing the payload doors, radiating excess heat, and retracting the KuThe approach and landing phase began when the orbiter vehicle was at an altitude of 3,000 m (10,000 ft) and traveling at 150 m/s (300 kn). Missions after The type of mission that the Space Shuttle was assigned to dictated the type of orbit that it entered. The space shuttle consists of the following major components: A reusable spacecraft with wings developed by the U.S. National Aeronautics and Space Administration (NASA) for human spaceflight missions.

Early missions routinely ferried satellites, which determined the type of orbit that the orbiter vehicle would enter. The on-orbit operations, such as experiments, payload deployment, and EVAs, were conducted primarily by the mission specialists who were specifically trained for their intended missions and systems. This included orbital laboratories,The Remote Manipulator System (RMS), also known as Canadarm, was a mechanical arm attached to the cargo bay.
