14. Shuttle  Basics

SPACE SHUTTLE
Shuttle Basics

Parts of the Space Transportation System 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. The Shuttle launches like a rocket, maneuvers in Earth orbit like a spacecraft and lands like an airplane. Each of the three Space Shuttle orbiters now in operation -- Discovery, Atlantis and Endeavour -- is designed to fly at least 100 missions. So far, altogether they have flown a combined total of less than one-fourth of that.

Columbia was the first Space Shuttle orbiter to be delivered to NASA's Kennedy Space Center, Fla., in March 1979. Columbia and the STS-107 crew were lost Feb. 1, 2003, during re-entry. The Orbiter Challenger was delivered to KSC in July 1982 and was destroyed in an explosion during ascent in January 1986. Discovery was delivered in November 1983. Atlantis was delivered in April 1985. Endeavour was built as a replacement following the Challenger accident and was delivered to Florida in May 1991. An early Space Shuttle Orbiter, the Enterprise, never flew in space but was used for approach and landing tests at the Dryden Flight Research Center and several launch pad studies in the late 1970s.

The Space Shuttle consists of three major components: the Orbiter which houses the crew; a large External Tank that holds fuel for the main engines; and two Solid Rocket Boosters which provide most of the Shuttle's lift during the first two minutes of flight. All of the components are reused except for the external fuel tank, which burns up in the atmosphere after each launch.

The longest the Shuttle has stayed in orbit on any single mission is 17.5 days on mission STS-80 in November 1996. Normally, missions may be planned for anywhere from five to 16 days in duration. The smallest crew ever to fly on the Shuttle numbered two people on the first few missions. The largest crew numbered eight people. Normally, crews may range in size from five to seven people. The Shuttle is designed to reach orbits ranging from about 185 kilometers to 643 kilometers (115 statute miles to 400 statute miles) high.

The Shuttle has the most reliable launch record of any rocket now in operation. Since 1981, it has boosted more than 1.36 million kilograms (3 million pounds) of cargo into orbit. More than than 600 crew members have flown on its missions. Although it has been in operation for almost 20 years, the Shuttle has continually evolved and is significantly different today than when it first was launched. NASA has made literally thousands of major and minor modifications to the original design that have made it safer, more reliable and more capable today than ever before.

Since 1992 alone, NASA has made engine and system improvements that are estimated to have tripled the safety of flying the Space Shuttle, and the number of problems experienced while a Space Shuttle is in flight has decreased by 70 percent. During the same period, the cost of operating the Shuttle has decreased by one and a quarter billion dollars annually -- a reduction of more than 40 percent. At the same time, because of weight reductions and other improvements, the cargo the Shuttle can carry has increased by 7.3 metric tons (8 tons.)

In managing and operating the Space Shuttle, NASA holds the safety of the crew as its highest priority.

Space Shuttle Endeavour (Orbiter Vehicle Designation: OV-105) is one of the retired orbiters of the Space Shuttle program of NASA, the space agency of the United States.[1] Endeavour was the fifth and final spaceworthy NASA space shuttle to be built, and first flew in May 1992 on mission STS-49 and its last mission STS-134 was in May 2011.[2][3] The STS-134 mission was originally planned as the final mission of the Space Shuttle program,[4] but with authorization of the STS-135 mission, Atlantis became the last Space Shuttle to fly.
The United States Congress authorized the construction of Endeavour in 1987 to replace Challenger, which was lost in the STS-51-L launch accident in 1986. Structural spares built during the construction of Discovery and Atlantis, two of the previous shuttles, were used in its assembly. NASA chose to build Endeavour from spares rather than refitting Enterprise or accepting a Rockwell International proposal to build two shuttles for the price of one of the original shuttles, on cost grounds.

The Space Shuttle Atlantis (Orbiter Vehicle Designation: OV‑104) was a Space Shuttle orbiter in the Space Shuttle fleet belonging to the National Aeronautics and Space Administration (NASA), the spaceflight and space exploration agency of the United States.[2] Atlantis was the fourth operational (and the next-to-the-last) Space Shuttle to be constructed by the Rockwell International company in Southern California, and it was delivered to the John F. Kennedy Space Center in eastern Florida in April 1985.[3][4] Atlantis was the only orbiter which lacked the ability to draw power from the International Space Station while docked there; it had to continue to provide its own power through fuel cells.[5]
The last mission of Atlantis was STS-135, the last flight of the Shuttle program. This final flight, authorized in October 2010, brought additional supplies to the International Space Station and took advantage of the processing performed for the Launch on Need mission, which would only have been flown in the event that Endeavour's STS-134 crew required rescue.[6] Atlantis launched successfully for the final time on 8 July 2011 at 16:29 UTC, landing at the John F. Kennedy Space Center on 21 July 2011 at 09:57 UTC.
By the end of its final mission, Atlantis had orbited the Earth 4,848 times, traveling nearly 126,000,000 mi (203,000,000 km) in space or more than 525 times the distance from the Earth to the Moon.
Atlantis was named after RV Atlantis, a two-masted sailing ship that operated as the primary research vessel for the Woods Hole Oceanographic Institution from 1930 to 1966.[7]

STS-1 was the first orbital flight of NASA's Space Shuttle program. Space Shuttle Columbia launched on 12 April 1981, and returned to Earth on 14 April, having orbited the Earth 37 times during its 54.5-hour mission. Columbia carried a crew of two – mission commander John W. Young and pilot Robert L. Crippen. It was the first American manned space flight since the Apollo-Soyuz Test Project on 15 July 1975. STS-1 was also the only US manned maiden test flight of a new spacecraft system, although it was the culmination of atmospheric testing of the Space Shuttle

7. Spacelab

Spacelab
Spacelab LM2
A major component of the Space Shuttle Program was Spacelab, primarily contributed by a consortium of European countries, and operated in conjunction with the United States and international partners.[38] Supported by a modular system of pressurized modules, pallets, and systems, Spacelab missions executed on multidisciplinary science, orbital logistics, international cooperation.[38] Over 29 missions flew on subjects ranging from astronomy, microgravity, radar, and life sciences, to name a few.[38] Spacelab hardware also supported missions such as Hubble (HST) servicing and space station resupply.[38] STS-2 and STS-3 provided testing, and the first full mission was Spacelab-1 (STS-9) launched on November 28, 1983.[38]
Spacelab formally began in 1973, after a meeting in Brussels, Belgium, by European heads of state.[21] Within the decade, Spacelab would go into orbit and provide not only Europe, but also the United States, with an orbital workshop and hardware system.[21] International cooperation, science, and exploration were realized on Spacelab.[38]

The Space Shuttle orbiter ranks second among the world's first spaceplanes, preceded only by the North American X-15 and followed by the Buran, SpaceShipOne, and the Boeing X-37.
The Space Shuttle Orbiter was the orbital spacecraft of the Space Shuttle program operated by NASA, the space agency of the United States.[1] The orbiter was a reusable winged "space-plane", a mixture of rockets, spacecraft, and aircraft. This space-plane could carry crews and payloads into low Earth orbit, perform on-orbit operations, then re-enter the atmosphere and land as a glider, returning its crew and any on-board payload to the Earth.
A total of six Orbiters were built for flight: Columbia, Challenger, Discovery, Atlantis, Endeavour and Enterprise. All were built by the Pittsburgh, PA based Rockwell International company. The first Orbiter to fly, Enterprise, took its maiden flight in 1977. Built solely for unpowered atmospheric test flights and landings, its take-off was from the back of a modified Boeing-747 cargo plane, the Shuttle Carrier Aircraft, while the remaining Orbiters were built for orbital space flights, launched vertically as part of the full Space Shuttle package. Enterprise was partially disassembled and retired after completion of critical testing.
Columbia was the first Orbiter to launch into space as a Space Shuttle, in 1981. The first launches of Challenger, Discovery, and finally Atlantis, followed in 1983, 1984 and 1985 respectively. In 1986, Challenger was destroyed in an accident after launch. Endeavour was built as Challenger's replacement, and was first launched in 1992. In 2003, Columbia was destroyed during re-entry, leaving just three remaining Orbiters. Discovery completed its final flight on March 9, 2011, and Endeavour completed its final flight on June 1, 2011. Atlantis completed the last ever Shuttle flight, STS-135, on July 21, 2011.
In addition to their crews and payloads, the reusable Orbiter carried most of the Space Shuttle System's liquid-fueled rocket propulsion system, but both the liquid hydrogen fuel and the liquid oxygen oxidizer for its three main rocket engines were fed from an external cryogenic propellant tank, and there were also two reusable large solid-fueled rocket boosters that helped to lift both the Orbiter and its external propellant tanks during approximately the first two minutes of its ascent into outer space. The orbiters also carried hypergolic fuels for use in their RCS systems and in the Orbital Manoeuvring System.

StatusAwaiting interior refurbishment at Johnson Space Center
Space Shuttle Explorer (honorary Orbiter Vehicle Designation: OV-100) is a full-scale, high-fidelity replica of the Space Shuttle. It was built in Apopka, Florida by Guard-Lee and installed at Kennedy Space Center Visitor Complex in 1993. It was built using schematics, blueprints and archival documents provided by NASA and by shuttle contractors such as Rockwell International. While many of the features on the replica are simulated, some of the model's core parts, including the Michelin tires used on the landing gear, are authentic to the Space Shuttle Program.[1] The model's length is 122.7 feet, its height is 54 feet, and its wingspan is 78 feet.
Internal details of the mock-up are not remarkably accurate, though the size and scope of the payload bay is correct.[citation needed] Externally, the mock-up features simulated thermal protection system tiles (bearing numbers, as the genuine flight articles used to), paneling that looks like reinforced carbon–carbon (RCC) panels on the leading edges of the wings, and actual Michelin tires on the landing gear which were flown in space. Handling points are also shown, but the external detailing does not extend to the inclusion of thermal blankets.[2]

4. History

History

Discovery rollout ceremony in October 1983
The spacecraft takes its name from four British ships of exploration named Discovery, primarily HMS Discovery, one of the ships commanded by Captain James Cook during his third and final major voyage from 1776 to 1779.
Others include
Discovery was the shuttle that launched the Hubble Space Telescope. The second and third Hubble service missions were also conducted by Discovery. It has also launched the Ulysses probe and three TDRS satellites. Discovery had been twice chosen as the "Return To Flight" Orbiter, first in 1988 after the 1986 Challenger disaster, and then for the twin "Return To Flight" missions in July 2005 and July 2006 after the 2003 Columbia disaster. Discovery also carried Project Mercury astronaut John Glenn, who was 77 at the time, back into space during STS-95 on October 29, 1998, making him the oldest person to go into space.[9]
Had the planned STS-62-A mission from Vandenberg Air Force Base in 1986 for the United States Department of Defense gone ahead, Discovery would have flown it. Its final mission, STS-133, landed on March 9, 2011, in Kennedy Space Center, Florida. After decommissioning and delivery, the spacecraft is displayed in Virginia at the Steven F. Udvar-Hazy Center, an annex of the Smithsonian Institution's National Air and Space Museum.[1]

Space Shuttle Discovery (Orbiter Vehicle Designation: OV-103) is one of the retired orbiters of the Space Shuttle program of NASA, the space agency of the United States,[4] and was operational from its maiden flight, STS-41-D on August 30, 1984, until its final landing during STS-133 on March 9, 2011. Discovery has flown more than any other spacecraft having completed 39 successful missions in over 27 years of service.[5]
In 1984, Discovery became the third operational orbiter following Columbia and Challenger,[6] and made its final touchdown at Kennedy Space Center on March 9, 2011 at 10:57:17 CST,[7] having spent a cumulative total of almost a full year in space. Discovery has performed both research and International Space Station (ISS) assembly missions. Discovery also flew the Hubble Space Telescope into orbit. Discovery was the first operational shuttle to be retired, followed by Endeavour

Successors

The Dragon spacecraft, one of the Space Shuttle's several successors, is seen here on its way to deliver cargo to the ISS
The Commercial Orbital Transportation Services (COTS) program began in 2006 with the purpose of creating commercially operated unmanned cargo vehicles to service the ISS.[24] The first of these vehicles, SpaceX's Dragon, became operational in 2012, and the second, Orbital Sciences' Cygnus, is expected to do so in 2013.[25] The Commercial Crew Development (CCDev) program was initiated in 2010 with the purpose of creating commercially operated manned spacecraft capable of delivering at least four crew members to the ISS, staying docked for 180 days and then returning them back to Earth.[26] These spacecraft are expected to become operational around 2017.[27]
Although the Constellation program was canceled it has been replaced with a very similar beyond low-Earth orbit program. The Orion spacecraft has been left virtually unchanged from its previous design. The planned Ares V rocket has been replaced with the smaller Space Launch System (SLS), which is planned to launch both Orion and other necessary hardware.[28] The Exploration Flight Test-1 (EFT-1), an unmanned test flight of Orion's crew module, is planned to be launched in 2014 on a Delta IV Heavy rocket.[29] Exploration Mission-1 (EM-1) is the unmanned initial launch of SLS, which is planned for 2017.[29] Exploration Mission-2 (EM-2) is the first manned flight of Orion and SLS and is scheduled for 2019.[29] EM-2 is 10-14 day mission planned to place a crew of four into Lunar orbit. As of March 2012, the destination for EM-3 and immediate destination focus for this new program is still in-flux.[30]

The Space Shuttle was a crewed, partially reusable low Earth orbital spacecraft operated by the U.S. National Aeronautics and Space Administration (NASA). Its official program name was Space Transportation System, taken from a 1969 plan for a system of reusable spacecraft of which it was the only item to be funded for development.[2] The first of four orbital test flights occurred in 1981, leading to operational flights beginning in 1982. It was used on a total of 135 missions from 1981 to 2011, all launched from the Kennedy Space Center, Florida.
Major missions included launching numerous satellites, interplanetary probes, the Hubble Space Telescope (HST), conducting space science experiments, and constructing and servicing the International Space Station. Major components included the orbiters, recoverable boosters, external tanks, payloads, and supporting infrastructure. Five space-worthy orbiters were built; two were lost in mission accidents.
The Space Shuttle at launch consisted of the Orbiter Vehicle (OV), one external tank (ET), and two Solid Rocket Boosters (SRBs). It was launched vertically like a conventional rocket with thrust from the two SRBs and three main engines. During launch, the external tank provided fuel for the orbiter's main engines. The SRBs and ET were jettisoned before the orbiter reached orbit. At the conclusion of the orbiter's space mission, it fired its thrusters to drop out of orbit and re-enter the lower atmosphere. The orbiter decelerated in the atmosphere before flying like a glider but with reaction control system thrusters before landing on a long runway. Columbia, Challenger, Discovery, Atlantis, and Endeavour were the space-capable orbiters that were built
