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 a 1969 plan for a system of reusable spacecraft where it was the only item funded for development. The first (STS-1) of four orbital test flights occurred in 1981, leading to operational flights (STS-5) beginning in 1982. 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. Operational missions launched numerous satellites, interplanetary probes, and the Hubble Space Telescope (HST), conducted science experiments in orbit, participated in the Shuttle-Mir program with Russia, and participated in construction and servicing of the International Space Station (ISS). The Space Shuttle fleet's total mission time was 1,323 days.
United States Merchant Marine are United States civilian mariners and U.S. civilian and federally owned merchant vessels. Both the civilian mariners and the merchant vessels are managed by a combination of the government and private sectors, and engage in commerce or transportation of goods and services in and out of the navigable waters of the United States. The Merchant Marine primarily transports cargo and passengers during peacetime; in times of war, the Merchant Marine can be an auxiliary to the United States Navy, and can be called upon to deliver military personnel and materiel for the military. Merchant Marine officers may also be commissioned as military officers by the Department of Defense. This is commonly achieved by commissioning unlimited tonnage Merchant Marine officers as Strategic Sealift Officers in the United States Navy Reserve.
A booster rocket is either the first stage of a multistage launch vehicle, or else a shorter-burning rocket used in parallel with longer-burning sustainer rockets to augment the space vehicle's takeoff thrust and payload capability. Boosters are traditionally necessary to launch spacecraft into low Earth orbit, and are especially important for a space vehicle to go beyond Earth orbit. The booster is dropped to fall back to Earth once its fuel is expended, a point known as booster engine cut-off (BECO).
The Space Shuttle Challenger disaster was a fatal accident in the United States space program that occurred on January 28, 1986, when the Space ShuttleChallenger (OV-099) broke apart 73 seconds into its flight, leading to the death of all seven crew members aboard; it was the first fatal accident involving an American spacecraft in flight. The mission, designated STS-51-L, was the tenth flight for the Challenger orbiter and twenty-fifth flight of the Space Shuttle fleet. The crew was scheduled to deploy a communications satellite and study Halley's Comet while they were in orbit. The spacecraft disintegrated over the Atlantic Ocean, off the coast of Cape Canaveral, Florida, at 11:39 a.m. EST.
The United States Merchant Marine Academy is a United States service academy in Kings Point, New York. It trains its midshipmen to serve as officers in the United States Merchant Marine, branches of the United States Armed Forces and the transportation industry. Midshipmen are trained in different fields such as marine engineering, navigation, ship's administration, maritime law, personnel management, international law, customs, and many other subjects important to the task of running a large ship.
The United States Navy maintains a number of its ships as part of a reserve fleet, often called the "Mothball Fleet". While the details of the maintenance activity have changed several times, the basics are constant: keep the ships afloat and sufficiently working as to be reactivated quickly in an emergency.
The Space Shuttle Solid Rocket Booster was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight and 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.
A solid rocket booster (SRB) is a large solid propellant motor used to provide thrust in spacecraft launches from initial launch through the first ascent. Many launch vehicles, including the Ariane 5, Atlas V, and space shuttle, have used SRBs to give launch vehicles much of the thrust required to place the vehicle into orbit. The space shuttle used two space shuttle SRBs, which were the largest solid propellant motors ever built and the first designed for recovery and reuse. The propellant for each solid rocket motor on the space shuttle weighed approximately 500,000 kilograms.
The National Defense Reserve Fleet (NDRF) consists of ships of the United States of America, mostly merchant vessels, that have been "mothballed" but can be activated within 20 to 120 days to provide shipping during national military emergencies, or non-military emergencies such as commercial shipping crises.
The Seafarers International Union or SIU is an organization of 12 autonomous labor unions of mariners, fishermen and boatmen working aboard vessels flagged in the United States or Canada. Michael Sacco has been its president since 1988. The organization has an estimated 35,498 members and is the largest maritime labor organization in the United States. Organizers founded the union on October 14, 1938. The Seafarers International Union arose from a charter issued to the Sailors Union of the Pacific by the American Federation of Labor as a foil against loss of jobs to the Congress of Industrial Organizations (CIO) and its Communist Party-aligned faction.
The Ares V was the planned cargo launch component of the cancelled NASA Constellation program, which was to have replaced the Space Shuttle after its retirement in 2011. Ares V was also planned to carry supplies for a human presence on Mars. Ares V and the smaller Ares I were named after Ares, the Greek god of war.
USS Sunbird (ASR-15) was a Chanticleer-class submarine rescue ship in the United States Navy.
The NASA recovery ships are two ships, the MV Liberty Star and the MV Freedom Star, that were tasked with retrieving spent Solid Rocket Boosters (SRBs) following the launch of Space Shuttle missions. Although owned by NASA, the ships were operated by Space Flight Operations contractor United Space Alliance. Following the end of the Space Shuttle program, and therefore booster recovery, NASA transferred both vessels to the Department of Transportation.
MV Liberty Star is a formerly NASA-owned and United Space Alliance-operated vessel which primarily served as an SRB recovery ship following the launch of Space Shuttle missions. It also performed tugboat duties and acted as a research platform. In 2012, it was transferred to the U.S. Department of Transportation for use as a training vessel at the United States Merchant Marine Academy as the TV Kings Pointer. Her sister ship is the MV Freedom Star.
USNS Rose Knot (T-AGM-14) was a World War II era United States Maritime Commission small cargo ship built in 1945 and delivered to the War Shipping Administration for operation through agent shipping companies and for periods by the Military Sea Transportation Service (MSTS). In 1957 the ship was transferred to the Air Force and converted into a missile range instrumentation ship which operated as USAFS Rose Knot on the U.S. Air Force's Eastern Test Range during the late 1950s and early 1960s. Rose Knot operated under an Air Force contract with Pan American Airways Guided Missile Range Division headquartered in Cocoa Beach, Florida. In July 1964 all Air Force tracking ships were transferred to MSTS for operation with the Air Force in operational control while the ships were at sea as tracking ships. Rose Knot had special facilities for supporting the manned space program and supported the early manned flights. The ship was owned by the U.S. government until sold for non transportation use in 1977.
The NASA Railroad is a Class III industrial short-line railroad at the Kennedy Space Center in Cape Canaveral, Florida. The railroad consists of 38 miles (61 km) of track connecting the mainline of the Florida East Coast Railway and trackage at the Cape Canaveral Space Force Station. NASA uses the railroad to deliver large or bulk materials to support its operations, particularly solid rocket boosters and chemicals such as helium and oxygen for rocket fuel.
The Type C6 ship is a United States Maritime Administration (MARAD) designation for a container ship developed during the transition years from moving goods by breakbulk cargo to containerization. The Type C4 ships Mariner class, arranged with its house/engine-room in the center of the vessel with cargo hatches at 4 forward and 2 aft, was very successful. Eleven of these Mariner ships were converted into Type C6 container ships, and eight vessels were new built. As of November 2020 only three C6 ships, the converted C4s, are extant. All three are crane ships in the National Defense Reserve Fleet.
USTS Patriot State, IMO number 5422409, formerly Santa Mercedes, was a training vessel of the United States Maritime Service. Originally build as a cargo/passenger liner for the Grace Line, it was later converted to a training vessel for the Massachusetts Maritime Academy.
Teleoperator Retrieval System was an uncrewed space tug ordered by NASA in the late 1970s to re-boost Skylab using the Space Shuttle.
MV Cape Lobos (T-AKR-5078),, was a Cape L-class roll-on/roll-off built in 1972.
