After the Challenger disaster, the crew members wore the Launch Entry Suit (LES), a partial-pressure version of the high-altitude pressure suits with a helmet. As humanity's first reusable spacecraft, the space shuttle pushed the bounds of discovery ever farther, requiring not only advanced technologies but the tremendous effort of a vast workforce. Its hull, measuring 16.3 meters in length, 19.7 meters wide and 7.5 meters in height, was constructed of conventional composite construction, with a ceramic and composite outer skin. The Space Shuttle was a partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. In 2007, NASA engineers devised a solution so Space Shuttle flights could cross the year-end boundary. Previous NASA spacecraft had used ablative heat shields, but those could not be reused. :164 The head of the NASA Office of Manned Space Flight, George Mueller, announced the plan for a reusable shuttle on August 10, 1968. The GPCs also controlled the multiple aerobraking S-turns, using only the roll axis, to dissipate excess speed without changing the angle-of-attack. The inertial upper stage, pressurized The improvement of expendable launch vehicles and the transition away from commercial payload on the Space Shuttle resulted in expendable launch vehicles becoming the primary deployment option for satellites. The Space Shuttle stops within 50 meters of Mir, which is approxi-mately one-half the length of a football field. Microsoft Encarta 98 Encyclopedia. modules or any specialized cradle for holding a payload are typical The MCDS displayed the flight information at the commander and pilot seats, as well as at the aft seating location, and also controlled the data on the HUD. :405–408 The Space Shuttle was not launched if its flight would run from December to January, as its flight software would have required the orbiter vehicle's computers to be reset at the year change. To minimize the impact of the shrinking module's ability to house scientific payloads, European developers come up with an ingenious ergonomic design, which utilized walls and ceiling of the laboratory for placement of hardware. The Air Force collaborated with NASA on the Dyna-Soar, and began training six pilots in June 1961. The commander sat in the front left seat, and the pilot sat in the front right seat, with two to four additional seats set up for additional crew members. The engine nozzles could gimbal ±10.5° in pitch, and ±8.5° in yaw during ascent to change the direction of their thrust to steer the Shuttle. To keep the engine thrust values consistent with previous documentation and software, NASA kept the original specified thrust as 100%, but had the RS-25 operate at higher thrust. The Mapping operations commenced shortly after. Payload to orbit: 28,803 kilograms Orbital Altitude: 185 to 643 kilometers apogee; Shuttle Mission Phases and Timelines. When the doors are opened, The aft fuselage Later that month, Rockwell began converting STA-099 to OV-099, later named Challenger. From the fifth flight, STS-5, until the loss of Challenger, the crew wore one-piece light blue nomex flight suits and partial-pressure helmets. portion of the bulkhead attaches to the vertical tail. The giant cylinder, higher than a 15-story building, with a length of 154-feet (47-meters) and a diameter of 27,5-feet (8.4-meters), is the largest single piece of the Space Shuttle. , The partial reusability of the Space Shuttle was one of the primary design requirements during its initial development. The middeck It was the only opportunity for a full view of the ISS with NASA's Space Shuttle and a European ATV cargo ship docked at … :174–175, NASA experienced significant delays in the development of the Space Shuttle's thermal protection system. Areas on the upper parts of the orbiter vehicle were coated in a white low-temperature reusable surface insulation, which provided protection for temperatures below 650 °C (1,200 °F). In addition to the weather at the launch site, conditions had to be acceptable at one of the Transatlantic Abort Landing sites and the SRB recovery area. In July 1969, the Space Shuttle Task Group issued a report that determined the Shuttle would support short-duration crewed missions and space station, as well as the capabilities to launch, service, and retrieve satellites. :408–411, The Space Shuttle crew varied per mission. ... length: 14.2 meters width: 5.4 meters height: 7.1 meters. :III–28 Landings at alternate airfields required the Shuttle Carrier Aircraft to transport the orbiter back to Cape Canaveral. 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 shuttle court is 44 feet long. The airlock Each seat has manual flight controls, including rotation The SLWT used the 2195 aluminum-lithium alloy, which was 40% stronger and 10% less dense than its predecessor, 2219 aluminum-lithium alloy. flight crew of three and a maximum rescued crew of seven. After achieving orbit, the crew would switch some of the GPCs functions from guidance, navigation, and control (GNC) to systems management (SM) and payload (PL) to support the operational mission. :372–376, The mid-deck contained the crew equipment storage, sleeping area, galley, medical equipment, and hygiene stations for the crew. The runway is located 3.2 km (2 miles) northwest of the Vehicle Assembly Building and is 4,572 meters (15,000ft) long and 91.4 meters (300ft) wide - about as wide as the length of a football field. In addition to the Dyna-Soar, the Air Force had conducted a study in 1957 to test the feasibility of reusable boosters. positioned on the left and the pilot's seat on the right. The original main combustion chamber operated at a maximum pressure of 226.5 bar (3,285 psi). The SkyFighter is the backbone of the Visitor attack force, and is capable of both atmospheric and space travel. During the development program, Rocketdyne determined that the engine was capable of safe reliable operation at 104% of the originally specified thrust. in the mid-fuselage payload bay, and the orbiter's main engines 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. and provides support for the nose section, the nose gear and the Once in space and after Shuttle Endeavour's payload bay doors were opened, the mast was deployed to it's full 60 meter (200 foot) length. Contract awarded to Rockwell International: January 29, 1979. The displays and controls on the left are for operating the orbiter, Microsoft Encarta 98 Encyclopedia. (2,325-cubic-foot) crew station module is a three-section pressurized , Three RS-25 engines, also known as the Space Shuttle Main Engines (SSME), were mounted on the orbiter's aft fuselage in a triangular pattern. All three RS-25 engines were required to reach 90% rated thrust by T−3 seconds, otherwise the GPCs would initiate an RSLS abort. In 1994, the LES was replaced by the full-pressure Advanced Crew Escape Suit (ACES), which improved the safety of the astronauts in an emergency situation. The ship holds a crew complement of six, … :175–177 At the time of its arrival at the KSC, Columbia still had 6,000 of its 30,000 tiles remaining to be installed. Facilities on the east coast of the US were planned for East Coast Abort Landings, while several sites in Europe and Africa were planned in the event of a Transoceanic Abort Landing. and translation hand controllers, rudder pedals and speed-brake in the midsection, or deck, of the crew module. In this case, the number of successes is determined by the number of successful Space Shuttle missions. :I-415, The beginning of the development of the RS-25 Space Shuttle Main Engine was delayed for nine months while Pratt & Whitney challenged the contract that had been issued to Rocketdyne. 11) to 20 meters. :III-22 The first Space Shuttle mission, STS-1, would be the first time NASA performed a crewed first-flight of a spacecraft. The length of the space shuttle is 37 meters from its pointed top end to the base of its rocket nozzles. The rocket motor, igniter, and nozzle were then shipped to Thiokol to be refurbished and reused on subsequent flights. In 1997, Honeywell began developing an integrated GPS/INS to replace the IMU, INS, and TACAN systems, which first flew on STS-118 in August 2007:402–403, While in orbit, the crew primarily communicated using one of four S band radios, which provided both voice and data communications. Teams wearing self-contained breathing gear tested for presence of hydrogen, hydrazine, monomethylhydrazine, nitrogen tetroxide, and ammonia to ensure the landing area was safe. International Space Station, ISS. The program tested aerodynamic characteristics that would later be incorporated in design of the Space Shuttle, including unpowered landing from a high altitude and speed. The nose cone housed the forward separation motors and the parachute systems that were used during recovery.
