The Space Transportation System (STS), also known as space shuttle, was developed by NASA as a meant to move both crew and cargo into low earth orbit. At launch the space shuttle was attached to an ET (external tank) and two SRB (solid rocket booster). The SRB jettison at 126 seconds in-flight and fall back down to earth where they would be picked up and refurbished for another launch. The ET will not be reused.
Orbiter[edit]
The STS Orbiter was the primary component of the STS and the only part of the STS stack, which reached orbit. It was a mixture between spacecraft and aircraft, landing as a glider after a long lifting reentry.
Orbital Maneuvering System (OMS)[edit]
The OMS would provide propulsion for the orbiter during the orbit phase of flight. The OMS wass used for orbit insertion, orbit circularization, orbit transfer, rendezvous, and deorbit. The OMS may be used to provide thrust above 70,000 feet altitude. Each OMS pod could provide more than 1,000 pounds of propellant to the RCS. Amounts available for interconnect depend on loading and number of OMS starts during the mission.
The OMS was housed in two independent pods on each side of the orbiter’s aft fuselage. The pods, which also housed the aft reaction control system (RCS), are referred to as the OMS/RCS pods. Each pod contained one OMS engine and the hardware needed to pressurize, store, and distribute the propellants to perform OMS engine burns. Normally, OMS maneuvers were done using both OMS engines together; however, a burn could be performed using only one of the OMS engines. For velocity changes less than 6 fps (2 m/s), RCS was used. For velocity changes greater than 6 fps, a single OMS engine burn was preferred, because engine lifetime concerns make it desirable to minimize engine starts. Two OMS engines were used for large velocity changes, or for critical burns. Propellant from one pod could be fed to the engine in the other pod through crossfeed lines that connected the left and right OMS pods. The OMS had important interfaces with the data processing system and the electrical power system. The OMS valves and gimbal actuators received commands, and the system returned some data to the general purpose computers through multiplexer/demultiplexer units. Electrical power was supplied to the OMS through main buses, control buses, and alternating current buses for the operation of switches, valves, instrumentation, gimbal actuators, and heaters.
The OMS/RCS pods were designed to be reused for up to 100 missions with only minor repair, refurbishment, and maintenance. The pods were removable to facilitate orbiter turnaround, if required.
Engines[edit]
The OMS engines were designated left and right, descriptive of location. The engines were located in gimbal mounts that allow the engine to pivot left and right and up and down under the control of two electromechanical actuators. This gimbal system provided for vehicle steering during OMS burns by controlling the direction of the engine thrust in pitch and yaw (thrust vector control) in response to commands from the digital autopilot or from the manual controls.
The OMS engines could be used singularly by directing the thrust vector through the orbiter center of gravity or together by directing the thrust vector of both engines parallel to the X axis. During a two-OMS-engine burn, the RCS would come into operation only if the attitude or attitude rate limits are exceeded. However, during a one-OMS-engine burn, RCS roll control was required.
Each of the two OMS engines produced 6,000 pounds of thrust (26.7 kN). For a typical orbiter weight, both engines together would create an acceleration of approximately 2 ft/sec2 or 0.06 g’s. Using up a fully loaded tank, the OMS could provide a total velocity change of approximately 1,000 ft/sec (304.8 m/s). Orbital insertion burns and deorbit burns each typically required a velocity change of about 100–500 ft/sec. The velocity change required for orbital adjustment is approximately 2 ft/sec (0.61 m/s) for each nautical mile of altitude change. Each OMS engines were capable of 1,000 starts and 15 hours of cumulative firing. The minimum duration of an OMS engine firing wass 2 seconds.
The OMS engines used monomethyl hydrazine as the fuel and nitrogen tetroxide as the oxidizer. These propellants are hypergolic, which means that they ignite when they come in contact with each other; therefore, no ignition device is needed. Both propellants remained liquid at the temperatures normally experienced during a mission, however, electrical heaters wre located throughout the OMS pods to prevent any freezing of propellants during long periods in orbit when the system was not in use.
Each OMS engine had a gaseous nitrogen tank that would provided pressurized nitrogen to operate the engine valves. The OMS engine would not have propellant pumps; propellant flow to the engines was maintained by pressurizing the propellant tanks with helium.
In the OMS engine, fuel was burned with oxidizer to produce thrust. The major elements of the OMS engine were the bipropellant valve assembly, the injector plate, the thrust chamber, and the nozzle.
The propellants ignite on contact, so theoretically the OMS engines could get ignited as often as desired, but the number of restarts were limited by the supply of N2 used for operating the valves and purging the fuel lines of the engines, which was only enough for ten restarts.
Differences between the orbiters[edit]
Columbia[edit]
Columbia (OV-102) was the first space-rated orbiter and was always the heaviest of the fleet. She was always the unique one with her SILTS(Shuttle Infrared Lee-side Temperature Sensing) pod on her vertical tail and the black wing chines. She was the only orbiter that never flew an ISS or Mir mission due to her mass.
However, her next mission following STS-107 was scheduled to be STS-118, going to ISS to deliver and install the S5 truss segment. Columbia was destroyed on reentry on STS-107, however, and STS-118 was later flown by Endeavour. Columbia was also capable of 16-day Extended Duration Orbiter(EDO) missions thanks the EDO cryokit in her payload bay.
Challenger[edit]
Challenger (OV-099) started out as Structural Test Article-099(STA-099) but when NASA decided against modifying Enterprise(OV-101) they decided to upgrade STA-099 into a spaceflight capable condition. During this refurbishment process she was known as OV-101M for a short while until she was later redesignated OV-099 keeping her STA number.
She was also a bit lighter than Columbia allowing her to perform IUS(Inertial Upper Stage) missions. Challenger had been modified at KSC to be able to support the Centaur G/G Prime upperstages, but she was destroyed during the launch of STS-51L prior to carrying any Centaur upperstages.
Discovery[edit]
Discovery (OV-103) was originally slated to become the "Air Force orbiter" stationed at Vandenberg AFB flying polar-orbit missions from Space Launch Complex-6(SLC-6, pronounced "slick six" ). However, the Challenger accident happened prior to the first Vandenberg AFB flight and the Air Force withdrew from the Shuttle program. She was then selected to fly the Return To Flight mission, STS-26R carrying TDRS-C.
Discovery also carried significant payloads such as the Ulysses Solar Polar Mission spacecraft and the Hubble Space Telescope. After Columbia, it looked for a while that Atlantis would fly STS-114, the Return To Flight mission. However, when engineers found problems with the actuators in the Rudder/Speedbrakes of the fleet, Discovery was selected once again to return the fleet to flight. She was retired in February 24, 2011.
Atlantis[edit]
Atlantis (OV-104) was pretty similar to Discovery, not much difference in mass or exterior appearance. Atlantis was used to launch Galileo to Jupiter and Magellan to Venus. Atlantis was the first orbiter to ever dock with Mir on STS-71 in July 1995. He was retired in July 8, 2011.
Atlantis is also the space shuttle that comes with the default Orbiter distribution.
Endeavour[edit]
Endeavour (OV-105) was built as replacement for Challenger utilizing spare parts NASA opted to build along with Discovery and Atlantis. Endeavour was the first orbiter delivered with an EDO capability and a 40 ft diameter drag chute used after touchdown to brake the orbiter on the runway. He was retired in May 16, 2011.
