The Shuttle Avionics Integration Laboratory (SAIL) was a facility at Lyndon B. Johnson Space Center in Houston, Texas, US.
The Shuttle Avionics Integration Laboratory (SAIL) was a facility at Lyndon B. Johnson Space Center in Houston, Texas, US.
It was the only facility in the Space Shuttle Program where actual orbiter hardware and flight software can be integrated and tested in a simulated flight environment. It supported the entire Space Shuttle program to perform integrated verification tests. It also contained Firing Room Launch Equipment identical to that used at KSC. Thus, complete ground verifications, as well as countdown and abort operations, could be tested and simulated.
The testing process is extensive and rigorous; the software on the Shuttle is often considered to be among the most bug-free of operational systems.
The laboratory contains a complete avionics mock-up of a Shuttle, designated OV-095. While only a skeleton of an orbiter, the electronics are identical in position and type to those used on the Shuttle; it is a sufficiently faithful replica that crews sometimes prefer to use it to train on, rather than the training simulators.
NASA personnel who have been assigned to SAIL testing include Charlie Bolden (former NASA Administrator), Michael Coats (former Director at JSC NASA), Brewster Shaw (Boeing Vice President of Space Exploration Division) and Al Crews (selected as an astronaut for the X-20 Dyna-Soar).The first SAIL commander was James E. Westom of Rockwell International, retired Major USAF. He flew the Approach and Landing phase in SAIL before Space Shuttle Enterprise was launched off the top of the NASA C-747 airplane to prove it could fly on its own in the atmosphere.
The SAIL facility will be renovated and recreated as a stop on the Space Center Houston Level 9 Tour, a separate add-on to the visitor's center admission in which tourists are given entrance to buildings normally off limits to visitors. [1]
The Space Shuttle is a retired, partially reusable low Earth orbital spacecraft system operated from 1981 to 2011 by the U.S. National Aeronautics and Space Administration (NASA) as part of the Space Shuttle program. Its official program name was Space Transportation System (STS), taken from the 1969 plan led by U.S. Vice President Spiro Agnew for a system of reusable spacecraft where it was the only item funded for development.
Space Shuttle Columbia (OV-102) was a Space Shuttle orbiter manufactured by Rockwell International and operated by NASA. Named after the first American ship to circumnavigate the globe, and the female personification of the United States, Columbia was the first of five Space Shuttle orbiters to fly in space, debuting the Space Shuttle launch vehicle on its maiden flight on April 12, 1981 and becoming the first ever spacecraft to be re-used after its first flight when it launched on STS-2 on November 12, 1981. As only the second full-scale orbiter to be manufactured after the Approach and Landing Test vehicle Enterprise, Columbia retained unique external and internal features compared to later orbiters, such as test instrumentation and distinctive black chines. In addition to a heavier aft fuselage and the retention of an internal airlock throughout its lifetime, these made Columbia the heaviest of the five spacefaring orbiters; around 1,000 kilograms heavier than Challenger and 3,600 kilograms heavier than Endeavour when originally constructed. Columbia also carried ejection seats based on those from the SR-71 during its first six flights until 1983, and from 1986 onwards carried an imaging pod on its vertical stabilizer.
Marshall Space Flight Center, located in Redstone Arsenal, Alabama, is the U.S. government's civilian rocketry and spacecraft propulsion research center. As the largest NASA center, MSFC's first mission was developing the Saturn launch vehicles for the Apollo program. Marshall has been the lead center for the Space Shuttle main propulsion and external tank; payloads and related crew training; International Space Station (ISS) design and assembly; computers, networks, and information management; and the Space Launch System. Located on the Redstone Arsenal near Huntsville, MSFC is named in honor of General of the Army George C. Marshall.
The Lyndon B. Johnson Space Center (JSC) is NASA's center for human spaceflight in Houston, Texas, where human spaceflight training, research, and flight control are conducted. It was renamed in honor of the late US president and Texas native, Lyndon B. Johnson, by an act of the United States Senate on February 19, 1973.
The Shuttle Carrier Aircraft (SCA) are two extensively modified Boeing 747 airliners that NASA used to transport Space Shuttle orbiters. One (N905NA) is a 747-100 model, while the other (N911NA) is a short-range 747-100SR. Both are now retired.
Brewster Hopkinson Shaw Jr. is a retired NASA astronaut, U.S. Air Force colonel, and former executive at Boeing. Shaw was inducted into the U.S. Astronaut Hall of Fame on May 6, 2006.
Andrew Michael "Andy" Allen is a retired American astronaut. A former Marine aviator and lieutenant colonel, he worked as a test pilot before joining NASA in 1987. He flew three Space Shuttle missions before retiring in 1997.
STS-105 was a mission of the Space Shuttle Discovery to the International Space Station, launched from Kennedy Space Center, Florida, 10 August 2001. This mission was Discovery's final mission until STS-114, because Discovery was grounded for a refit, and then all Shuttles were grounded in the wake of the Columbia disaster. The refit included an update of the flight deck to the glass cockpit layout, which was already installed on Atlantis and Columbia.

The Boeing X-37, also known as the Orbital Test Vehicle (OTV), is a reusable robotic spacecraft. It is boosted into space by a launch vehicle, then re-enters Earth's atmosphere and lands as a spaceplane. The X-37 is operated by the Department of the Air Force Rapid Capabilities Office, in collaboration with United States Space Force, for orbital spaceflight missions intended to demonstrate reusable space technologies. It is a 120-percent-scaled derivative of the earlier Boeing X-40. The X-37 began as a NASA project in 1999, before being transferred to the United States Department of Defense in 2004. Until 2019, the program was managed by Air Force Space Command.
The Shuttle Training Aircraft (STA) is a former NASA training vehicle that duplicated the Space Shuttle's approach profile and handling qualities, allowing pilots to simulate Shuttle landings under controlled conditions before attempting the task on board the orbiter. The STA was also flown to assess weather conditions just prior to Space Shuttle launches and landings.
Flight controllers are personnel who aid space flight by working in such Mission Control Centers as NASA's Mission Control Center or ESA's European Space Operations Centre. Flight controllers work at computer consoles and use telemetry to monitor various technical aspects of a space mission in real-time. Each controller is an expert in a specific area and constantly communicates with additional experts in the "back room". The flight director, who leads the flight controllers, monitors the activities of a team of flight controllers, and has overall responsibility for success and safety.
The Hitchhiker Program (HH) was a NASA program established in 1984 and administered by the Goddard Space Flight Center (GSFC) and the Marshall Space Flight Center (MSFC). The program was designed to allow low-cost and quick reactive experiments to be placed on board the Space Shuttle. The program was discontinued after the Space Shuttle Columbia disaster of STS-107.
The Materials International Space Station Experiment (MISSE) is a series of experiments mounted externally on the International Space Station (ISS) that investigates the effects of long-term exposure of materials to the harsh space environment.
The Approach and Landing Tests were a series of sixteen taxi and flight trials of the prototype Space Shuttle Enterprise that took place between February and October 1977 to test the vehicle's flight characteristics. Of the sixteen taxi-tests and flights, eleven saw Enterprise remain mated to the Shuttle Carrier Aircraft (SCA), while the final five had the shuttle jettisoned from the SCA, with the on-board crew flying and landing the spacecraft.
NASA's Christopher C. Kraft Jr. Mission Control Center, also known by its radio callsign, Houston, is the facility at the Lyndon B.
