[13]:II-87–88 The SSPTS was first used on STS-118, and was installed on Discovery and Endeavour. Early in the Space Shuttle program, NASA flew with payload specialists, who were typically systems specialists who worked for the company paying for the payload's deployment or operations. The orbiter's vertical stabilizer was swept backwards at 45°, and contained a rudder that could split to act as a speed brake. The orbiter vehicle was attached to the ET at two umbilical plates, which contained five propellant and two electrical umbilicals, and forward and aft structural attachments. The SRBs were assembled and attached to the external tank on the MLP. 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. [10][11] The Air Force Flight Dynamics Laboratory argued that a straight-wing design would not be able to withstand the high thermal and aerodynamic stresses during reentry, and would not provide the required cross-range capability. The orbiter contains two star trackers to align the IMUs while in orbit. Later that month, Rockwell began converting STA-099 to OV-099, later named Challenger. or EVA. Length: Shuttle - 56.14 meters / Orbiter - 37.23 meters Height: Orbiter on Runway - 17.27 meters Weight: At liftoff - 2,041,166 kilograms / At landing - 104,326 kilograms Max. [13]:III–13, In addition to the pre-planned landing airfields, there were 85 agreed-upon emergency landing sites to be used in different abort scenarios, with 58 located in other countries. Following the retirement of the Space Shuttle, N905NA was put on display at the JSC, and N911NA was put on display at the Joe Davis Heritage Airpark in Palmdale, California. [17]:430 Once they were returned to Cape Canaveral, they were cleaned and disassembled. 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. 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. Its casing consisted of 11 steel sections which made up its four main segments. The cockpit, The internal airlock was replaced with an external airlock in the payload bay on Discovery, Atlantis, and Endeavour to improve docking with Mir and the ISS, along with the Orbiter Docking System. [8]:137 After the Space Shuttle arrived at one of the two launchpads, it would connect to the Fixed and Rotation Service Structures, which provided servicing capabilities, payload insertion, and crew transportation. The landing gear was deployed 10 seconds prior to touchdown, when the orbiter was at an altitude of 91 m (300 ft) and traveling 150 m/s (288 kn). The orbiter vehicle's reentry was controlled by the GPCs, which followed a preset angle-of-attack plan to prevent unsafe heating of the TPS. Following separation, they deployed drogue and main parachutes, landed in the ocean, and were recovered by the crews aboard the ships MV Freedom Star and MV Liberty Star. The rising costs of development and the prioritization of Project Gemini led to the cancellation of the Dyna-Soar program in December 1963. The ET continued on a ballistic trajectory and broke up during reentry, with some small pieces landing in the Indian or Pacific Ocean. Studio model. and . Figure 2: Onlookers view the launch of STS 121. "Space Shuttle."

The orbiter, which resembles an airplane and is the part that houses the astronauts and flies into space. out of the payload bay or retrieved and secured for return to Earth. 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 … may not be attached directly to the orbiter but to payload carriers At 8 minutes 44 seconds prior to landing, the crew deployed the air data probes, and began lowering the angle-of-attack to 36°. [13]:II–26–33, The orbiter was equipped with an avionics system to provide information and control during atmospheric flight. The SRB's subcomponents were the solid-propellant motor, nose cone, and rocket nozzle. The orbiter vehicle reoriented itself to a nose-forward position with a 40° angle-of-attack, and the forward reaction control system (RCS) jets were emptied of fuel and disabled prior to reentry. It is bisected by a net 2 feet, 6 inches wide, the top of which is suspended 5 feet from the surface of the court at the centerline. At an altitude of 46 km (150,000 ft), the orbiter vehicle opened its speed brake on the vertical stabilizer.

The 65.8-cubic-meter [9][8]:19–22, In December 1968, NASA created the Space Shuttle Task Group to determine the optimal design for a reusable spacecraft, and issued study contracts to General Dynamics, Lockheed, McDonnell Douglas, and North American Rockwell. [13]:III-398 From then until the launch of Crew Dragon Demo-2 on May 30, 2020, the US launched its astronauts aboard Russian Soyuz spacecraft. This area houses the pressurized crew module and those on the right are for operating and handling the payloads. Additionally, the orbiter deployed a high-bandwidth Ku band radio out of the cargo bay, which could also utilized as a rendezvous radar. The rear of the orbiter contained the Space Shuttle Main Engines (SSME), which provided thrust during launch, as well as the Orbital Maneuvering System (OMS), which allowed the orbiter to achieve, alter, and exit its orbit once in space. [17]:425 After expending their fuel, the SRBs were jettisoned approximately two minutes after launch at an altitude of approximately 46 km (150,000 ft). contains two spacesuits, expendables for two six-hour payload EVAs [4] The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. In February 1977, Enterprise began the Approach and Landing Tests and underwent captive flights, where it remained attached to the Shuttle Carrier Aircraft for the duration of the flight. The space shuttle is the world's first reusable spacecraft, and the first spacecraft in history that can carry large satellites both to and from orbit. controllers. After the loss of Challenger, NASA resumed production of Endeavour in September 1987. NASA's pricing, which was below cost, was lower than expendable launch vehicles; the intention was that the high volume of Space Shuttle missions would compensate for early financial losses. The shuttle court is 44 feet long. All three RS-25 engines were required to reach 90% rated thrust by T−3 seconds, otherwise the GPCs would initiate an RSLS abort. The upper [13]:II–1 The orbiter vehicle flew to one of the two Heading Alignment Cones, located 48 km (30 mi) away from each end of the runway's centerline, where it made its final turns to dissipate excess energy prior to its approach and landing. These ranged from 7.6 meters (Fig. [34] Between T−6.6 seconds and T−3 seconds, while the RS-25 engines were firing but the SRBs were still bolted to the pad, the offset thrust caused the Space Shuttle to pitch down 650 mm (25.5 in) measured at the tip of the external tank; the 3-second delay allowed the stack to return to nearly vertical before SRB ignition. The RMS was built by the Canadian company Spar Aerospace, and was controlled by an astronaut inside the orbiter's flight deck using their windows and closed-circuit television. [13]:II–187, At approximately T+123 seconds and an altitude of 46,000 meters (150,000 ft), pyrotechnic fasteners released the SRBs, which reached an apogee of 67,000 meters (220,000 ft) before parachuting into the Atlantic Ocean. [17]:422, For the first two missions, STS-1 and STS-2, the ET was covered in 270 kg (595 lb) of white fire-retardant latex paint to provide protection against damage from ultraviolet radiation. the four aft radiator panels radiate from the upper side only. The [30] The Shuttle Launch Weather Officer monitored conditions until the final decision to scrub a launch was announced. and . The dimensions of the completed ISS research facility will be approximately 356 feet (109 meters) by 240 feet (73 meters), or slightly larger than a football field. and translation hand controllers, rudder pedals and speed-brake Four fully operational orbiters were initially built: Columbia, Challenger, Discovery, and Atlantis. docking, Spacelab and extravehicular operations. The facility includes a 150 x 168 meter(490x550ft) parking apron and a 3.2 km (2 mile) tow-w… [47] NASA management was criticized afterwards for accepting increased risk to the crew in exchange for higher mission rates. Teams wearing self-contained breathing gear tested for presence of hydrogen, hydrazine, monomethylhydrazine, nitrogen tetroxide, and ammonia to ensure the landing area was safe. The displays and controls on the left are for operating the orbiter, [13]:III-355 STS-135 launched on July 8, 2011, and landed at the KSC on July 21, 2011, at 5:57 a.m. EDT (09:57 UTC). Mapping operations commenced shortly after. [6]: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. During the development program, Rocketdyne determined that the engine was capable of safe reliable operation at 104% of the originally specified thrust. The orbiter vehicle maneuvered to an upside down, tail first orientation and began a 2-4 minute OMS burn approximately 20 minutes before it reentered the atmosphere. in the mid-fuselage payload bay, and the orbiter's main engines Scientists conducted a successful test of a German-made prototype of a future European space shuttle on Saturday. The LH2 comprised the bulk of the ET, and was 29 m (96.7 ft) tall. Rather than award a contract based upon initial proposals, NASA announced a phased approach for the Space Shuttle contracting and development; Phase A was a request for studies completed by competing aerospace companies, Phase B was a competition between two contractors for a specific contract, Phase C involved designing the details of the spacecraft components, and Phase D was the production of the spacecraft. The length of the space shuttle is 37 meters from its pointed top end to the base of its rocket nozzles. [17]:408–411, The Space Shuttle crew varied per mission. The total liftoff weight for a space shuttle was approximately 4.4 million pounds (1,995,806 kg), or over 2,000 tons. arm remotely controlled from the flight deck of the orbiter. Once the orbiter was secured, it was towed to the OPF to be inspected, repaired, and prepared for the next mission. The wing you are standing under is almost 10 feet (3 meters) from the deck, and the orbiter’s full wingspan is 78 feet (23.8 meters). The mission cycle of the Shuttle is quite complex. As Atlantis was prepared for the final launch-on-need mission, the decision was made in September 2010 that it would fly as STS-135 with a four-person crew that could remain at the ISS in the event of an emergency. The outboard antenna, which remained in its stowed position atop the mast, was then slowly flipped over the end of the mast into its operation position. [13]:III−490, On January 28, 1986, STS-51-L disintegrated 73 seconds after launch, due to the failure of the right SRB, killing all seven astronauts on board Challenger. 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. It has 305 meters (1000ft) of pavedoverruns at each end and the paving thickness is 40.6cm (15ninches) at thecenter. On October 18, 1995, ESA council slashed the length of the Columbus module to 6.7 meters, or half of its original size. After the Challenger disaster as a result of an O-ring failing at low temperature, the SRBs were redesigned to provide a constant seal regardless of the ambient temperature. Length: Shuttle - 56.14 meters / Orbiter - 37.23 meters Height: Orbiter on Runway - 17.27 meters Weight: At liftoff - 2,041,166 kilograms / At landing - 104,326 kilograms Max. Five complete Space Shuttle orbiter vehicles were built and flown on a total of 135 missions from 1981 to 2011, launched from the Kennedy Space Center (KSC) in Florida. The exterior of the ET was covered in orange spray-on foam to allow it to survive the heat of ascent. return. On earlier missions the Space Shuttle remained in the heads-down orientation to maintain communications with the tracking station in Bermuda, but later missions, beginning with STS-87, rolled to a heads-up orientation at T+6 minutes for communication with the tracking and data relay satellite constellation. [8]:106–107, The Orbital Maneuvering System (OMS) consisted of two aft-mounted AJ10-190 engines and the associated propellant tanks. The instrument panels contained over 2,100 displays and controls, and the commander and pilot were both equipped with a heads-up display (HUD) and a Rotational Hand Controller (RHC) to gimbal the engines during powered flight and fly the orbiter during unpowered flight. This became the basis for the aerospaceplane, a fully reusable spacecraft that was never developed beyond the initial design phase in 1962–1963. [13]:III–10, The type of mission that the Space Shuttle was assigned to dictated the type of orbit that it entered. deck is designed in the usual pilot/copilot arrangement, which permits The bay, 18.3 m long and 4.6 m wide (60 ft by 15 ft), has payload attachment points along its full length, and is adaptable enough to accommodate as many as five unmanned spacecraft of various sizes and shapes in one mission. STS-6 and STS-7 used SRBs that were 2,300 kg (5,000 lb) lighter than the standard-weight cases due to walls that were 0.10 mm (.004 in) thinner, but were determined to be too thin. During ascent, maneuvering, reentry, and landing, the four PASS GPCs functioned identically to produce quadruple redundancy, and would error check their results. Of these, two were lost in mission accidents: Challenger in 1986 and Columbia in 2003, with a total of fourteen astronauts killed. Minibuses, or shuttle buses, are vehicles with passenger capacities below the larger full-size bus and more than the smaller minivan.
