2O) occurs within the engine's combustion chamber. The reaction products are then expanded and accelerated in the engine bell to provide thrust. Due to their hypergolic characteristics these two chemicals are easily started and restarted without an ignition source, which makes them ideal for spacecraft maneuvering systems.
During the early design process of the orbiter, the forward RCS thrusters were to be hidden underneath retractable doors, which would open once the orbiter reached space. These were omitted in favor of flush-mounted thrusters for fear that the RCS doors would remain stuck open and endanger the crew and orbiter during re-entry.

The Space Shuttle orbiter had three sets of

Landing gear is the undercarriage of an aircraft or spacecraft that is used for takeoff or landing. For aircraft it is generally needed for both. It was also formerly called ''alighting gear'' by some manufacturers, such as the Glenn L. Martin ...
which emerged downwards through doors in the heat shield. As a weight-saving measure, the gear could not be retracted once deployed. Since any premature extension of the landing gear would very likely have been catastrophic (as it opened through the heat shield layers), the landing gear could only be lowered by manual controls, and not by any automatic system.
Similarly, since the Shuttle landed at high speed and could not abort its landing attempt, the gear had to deploy reliably on the first try every time. The gear were unlocked and deployed by triple redundant hydraulics, with the gear doors actuated by mechanical linkages to the gear strut. If all three hydraulic systems failed to release the landing gear uplocks within one second of the release command, pyrotechnic charges automatically cut the lock hooks and a set of springs deployed the gear.

ahead of it.
The first operational orbiter, ''Columbia'', originally had the same markings as ''Enterprise'', although the letters "USA" on the right wing were slightly larger and spaced farther apart. ''Columbia'' also had black tiles which ''Enterprise'' lacked on its forward RCS module, around the cockpit windows, and on its vertical stabilizer. ''Columbia'' also had distinctive black
chines on the forward part of its upper wing surfaces, which none of the other orbiters had.
![NASA Worm logo (gray)](https://upload.wikimedia.org/wikipedia/commons/a/aa/NASA_Worm_logo_%28gray%29.svg)
''Challenger'' established a modified marking scheme for the shuttle fleet that would be matched by ''Discovery'', ''Atlantis'' and ''Endeavour''. The letters "USA" in black above an American flag were displayed on the left wing, with the NASA "worm" logotype in gray centered above the name of the orbiter in black on the right wing. Also, the name of the orbiter was inscribed not on the payload bay doors, but on the forward fuselage just below and behind the cockpit windows. This would make the name visible when the orbiter was photographed in orbit with the doors open. ''Challenger'' also had black tiles on the tip of its vertical stabilizer much like ''Columbia'', which the other orbiters lacked.
In 1983, ''Enterprise'' had its wing markings changed to match ''Challenger'', and the NASA "worm" logotype on the aft end of the payload bay doors was changed from gray to black. Some black markings were added to the nose, cockpit windows and vertical tail to more closely resemble the flight vehicles, but the name "Enterprise" remained on the payload bay doors as there was never any need to open them. ''Columbia'' had its name moved to the forward fuselage to match the other flight vehicles after
STS-61-C, during the 1986–1988 hiatus when the shuttle fleet was grounded following the
loss of ''Challenger'', but retained its original wing markings until its last overhaul (after

), and its unique black chines for the remainder of its operational life.
![NASA logo](https://upload.wikimedia.org/wikipedia/commons/e/e5/NASA_logo.svg)
Beginning in 1998, the flight vehicles' markings were modified to incorporate the NASA
"meatball" insignia. The "worm" logotype, which the agency had phased out, was removed from the payload bay doors and the "meatball" insignia was added aft of the "United States" text on the lower aft fuselage. The "meatball" insignia was also displayed on the left wing, with the American flag above the orbiter's name, left-justified rather than centered, on the right wing. The three surviving flight vehicles, ''Discovery'', ''Atlantis'' and ''Endeavour'', still bear these markings as museum displays. ''Enterprise'' became the property of the

Lunar Module ''Challenger''.
While all of the orbiters were externally practically identical, they had minor differences in their interiors. New equipment for the Orbiters was installed in the same order that they underwent maintenance work, and the newer orbiters were constructed by Rockwell International, under NASA supervision, with some more advanced, lighter in weight, structural elements. Thus, the newer orbiters (''Discovery'', ''Atlantis'' and ''Endeavour'') had slightly more cargo capacity than ''Columbia'' or ''Challenger''.
The Space Shuttle orbiters were assembled at Rockwell's assembly facility in

A prefix is an affix which is placed before the Word stem, stem of a word. Adding it to the beginning of one word changes it into another word. For example, when the prefix ''un-'' is added to the word ''happy'', it creates the word ''unhappy'' ...
and suffix separated by a dash. The prefix for operational shuttles is OV, for Orbiter Vehicle. The suffix is composed of two parts: the series and the vehicle number; "0" was used for non-flight ready orbiters, and "1" was used for flight-ready orbiters. The vehicle number is sequentially assigned within the series, beginning with 1. Therefore, there can never be an OV-100 as it would read "Orbiter Vehicle Series 1 Vehicle 0". Many proposals to build a second generation of orbiters, externally compatible with the current system but internally new, refer to them as "OV-200" or "OV-2xx" in order to differentiate them from the "first generation", the OV-100s. This terminology is informal, and it is unlikely that any Shuttle-derived vehicle built will be given such designation. ''Challenger'' was originally intended to be used as a Structural Test Article (STA), rather than a flight-capable orbiter; as such, the numbering was changed when it was rebuilt. ''Enterprise'', on the other hand, was intended to be rebuilt into a flight-capable orbiter; it was found to be cheaper to rebuild STA-099 than OV-101, so it remained unflown. The designations were not altered, despite these changes in plans. An "OV-106" designation was given to the set of structural components manufactured to replace those used in the construction of ''Endeavour''; however, the contract for these was canceled shortly afterwards, and they were never completed. The "096" and "097" designators were given to structural test articles that were canceled, but while they exist in some NASA records, the NASA History Office has no official record of STA-096 and STA-097.
