STS-1 was the first orbital spaceflight of NASA's Space Shuttle program. The first orbiter, Columbia, launched on April 12, 1981, and returned on April 14, 1981, 54.5 hours later, having orbited the Earth 37 times. Columbia carried a crew of two—mission commander John W. Young and pilot Robert L. Crippen. It was the first American crewed space flight since the Apollo–Soyuz Test Project (ASTP) in 1975. STS-1 was also the maiden test flight of a new American spacecraft to carry a crew, though it was preceded by atmospheric testing (ALT) of the orbiter and ground testing of the Space Shuttle system.
The Lyndon B. Johnson Space Center (JSC) is NASA's center for human spaceflight, 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.
STS-2 was the second Space Shuttle mission conducted by NASA, and the second flight of the orbiter Columbia. The mission, crewed by Joe H. Engle and Richard H. Truly, launched on November 12, 1981, and landed two days later on November 14, 1981. STS-2 marked the first time that a crewed, reusable orbital vehicle returned to space. This mission tested the Shuttle Imaging Radar (SIR) as part of the OSTA-1 payload, along with a wide range of other experiments including the Shuttle robotic arm, commonly known as Canadarm. Other experiments or tests included Shuttle Multispectral Infrared Radiometer, Feature Identification and Location Experiment, Measurement of Air Pollution from Satellites, Ocean Color Experiment, Night/Day optical Survey of Lightning, Heflex Bioengineering Test, and Aerodynamic Coefficient Identification Package (ACIP). One of the feats accomplished was various tests on the Orbital Maneuvring System (OMS) including starting and restarting the engines while in orbit and various adjustments to its orbit. The OMS tests also helped adjust the Shuttle's orbit for use of the radar. During the mission, President Reagan called the crew of STS-2 from Mission Control Center in Houston.
STS-3 was NASA's third Space Shuttle mission, and was the third mission for the Space Shuttle Columbia. It launched on March 22, 1982, and landed eight days later on March 30, 1982. The mission, crewed by Jack R. Lousma and C. Gordon Fullerton, involved extensive orbital endurance testing of the Columbia itself, as well as numerous scientific experiments. STS-3 was the first shuttle launch with an unpainted external tank, and the only mission to land at the White Sands Space Harbor near Alamogordo, New Mexico. The orbiter was forced to land at White Sands due to flooding at its originally planned landing site, Edwards Air Force Base.
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.
The Space Shuttle Solid Rocket Booster (SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. A pair of these provided 85% of the Space Shuttle's thrust at liftoff and for the first two minutes of ascent. After burnout, they were jettisoned and parachuted into the Atlantic Ocean where they were recovered, examined, refurbished, and reused.
Brian Duffy is a retired U.S. Air Force colonel and a former NASA astronaut. He flew aboard four Space Shuttle missions.
The Space Shuttle external tank (ET) was the component of the Space Shuttle launch vehicle that contained the liquid hydrogen fuel and liquid oxygen oxidizer. During lift-off and ascent it supplied the fuel and oxidizer under pressure to the three RS-25 main engines in the orbiter. The ET was jettisoned just over 10 seconds after main engine cut-off (MECO) and it re-entered the Earth's atmosphere. Unlike the Solid Rocket Boosters, external tanks were not re-used. They broke up before impact in the Indian Ocean, away from shipping lanes and were not recovered.
Shuttle-derived vehicles (SDV) are space launch vehicles and spacecraft that use components, technology, and infrastructure originally developed for the Space Shuttle program.
A mobile launcher platform (MLP), also known as mobile launch platform, is a structure used to support a large multistage space vehicle which is assembled (stacked) vertically in an integration facility and then transported by a crawler-transporter (CT) to a launch pad. This becomes the support structure for launch.
Ares I was the crew launch vehicle that was being developed by NASA as part of the Constellation program. The name "Ares" refers to the Greek deity Ares, who is identified with the Roman god Mars. Ares I was originally known as the "Crew Launch Vehicle" (CLV).
Linda Ham is a former Constellation Program Transition and Technology Infusion Manager at NASA. She was formerly the program integration manager in the National Aeronautics and Space Administration (NASA) Space Shuttle Program Office and acting manager for launch integration. In this position, she chaired the mission management team for all shuttle flights between 2001 and 2003, including shuttle mission STS-107 that ended with the catastrophic destruction of Columbia upon its planned reentry into the Earth's atmosphere.
Criticism of the Space Shuttle program stemmed from claims that NASA's Space Shuttle program failed to achieve its promised cost and utility goals, as well as design, cost, management, and safety issues. Fundamentally, it failed in the goal of reducing the cost of space access. Space Shuttle incremental per-pound launch costs ultimately turned out to be considerably higher than those of expendable launchers. By 2011, the incremental cost per flight of the Space Shuttle was estimated at $450 million, or $18,000 per kilogram to low Earth orbit (LEO). In contrast, the comparable Proton launch vehicle is said to cost as little as $110 million, or around $5,000 per kilogram to LEO, despite not being reusable.
Launch Complex 39B (LC-39B) is the second of Launch Complex 39's three launch pads, located at NASA's Kennedy Space Center in Merritt Island, Florida. The pad, along with Launch Complex 39A, was first designed for the Saturn V launch vehicle, which at the time was the United States' most powerful rocket. Typically used to launch NASA's crewed spaceflight missions since the late 1960s, the pad is currently configured for use by the agency's Space Launch System rocket, a Shuttle-derived launch vehicle which is currently used in the Artemis program and subsequent Moon to Mars campaigns. The pad had also been leased by NASA to aerospace company Northrop Grumman, for use as a launch site for their Shuttle-derived OmegA launch vehicle, for National Security Space Launch flights and commercial launches, before the OmegA program was cancelled.
LeRoy Edward Cain is an American aerospace engineer who worked for NASA as a flight director, launch integration manager and deputy manager of the Space Shuttle Program. Cain may be best known to the public from footage and documentaries showing his work as the entry flight director for STS-107, the mission that ended in the catastrophic disintegration of Space Shuttle Columbia, February 1, 2003. Cain issued the famous "Lock the doors" command, initiating contingency procedures in mission control for the first time since the Space Shuttle Challenger disaster 17 years earlier.
DIRECT was a late-2000s proposed alternative super heavy lift launch vehicle architecture supporting NASA's Vision for Space Exploration that would replace the space agency's planned Ares I and Ares V rockets with a family of Shuttle-Derived Launch Vehicles named "Jupiter". It was intended to be the alternative to the Ares I and Ares V rockets which were under development for the Constellation program, intended to develop the Orion spacecraft for use in Earth orbit, the Moon, and Mars.
James Milton Heflin Jr. is a retired NASA official, who recently served as the associate director for technical activities at Johnson Space Center in Houston. Heflin also served as lead flight director for seven high-profile Space Shuttle missions, including the first to service and repair the Hubble Space Telescope and three that deployed inter-planetary probes.
The retirement of NASA's Space Shuttle fleet took place from March to July 2011. Discovery was the first of the three active Space Shuttles to be retired, completing its final mission on March 9, 2011; Endeavour did so on June 1. The final shuttle mission was completed with the landing of Atlantis on July 21, 2011, closing the 30-year Space Shuttle program.
Liberty was a 2011 launch vehicle concept proposed by Alliant Techsystems (ATK) and Astrium for phase 2 of the NASA Commercial Crew Development (CCDev) program intended to stimulate development of privately operated crew vehicles to low Earth orbit.
During the lifetime of the Space Shuttle, Rockwell International and many other organizations studied various Space Shuttle designs. These studies included different ways to increase shuttle payload capability, and crew capacity, and develop standalone reusable launch vehicles. A large focus of the program was on new shuttle boosters and an upgrade to the external tank but also looked to expand NASA's ability to launch deep space missions and build large modular space stations. Many of these concepts and studies would shape the concepts and programs of the 2000s such as the Constellation, Orbital Space Plane Program, and Artemis program.
