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.
The RS-25 engine consists of pumps, valves, and other components working in concert to produce thrust. Fuel (liquid hydrogen) and oxidizer (liquid oxygen) from the Space Shuttle's external tank entered the orbiter at the umbilical disconnect valves and from there flowed through the orbiter's main propulsion system (MPS) feed lines; whereas in the Space Launch System (SLS), fuel and oxidizer ...
Some devices that are used or proposed for use as thrusters are: Cold gas thruster; Electrohydrodynamic thruster, using ionized air (only for use in an atmosphere) Electrodeless plasma thruster, electric propulsion using ponderomotive force; Electrostatic ion thruster, using high-voltage electrodes; Hall effect thruster, a type of ion thruster
The solid rocket motors in each cluster of four are ignited by firing redundant NSD pressure cartridges into redundant confined detonating fuse manifolds. The separation commands issued from the orbiter by the SRB separation sequence initiate the redundant NSD pressure cartridge in each bolt and ignite the BSMs to effect a clean separation.
Those thrusters are on the spacecraft’s service module and are used to move the capsule around in orbit, particularly to adjust its position as it docks and undocks with the space station.
The act set out certain goals, such as being able to lift 70–100 tons into low earth orbit with evolvability to 130 tons, a target date of 31 December 2016 for the system to be fully operational, and a directive to use "to the extent practicable" existing components, hardware, and workforce from the Space Shuttle and from Ares I.

In some parts of the space industry an LAE is also referred to as a liquid apogee motor (LAM), a liquid apogee thruster (LAT) and, depending on the propellant, a dual-mode liquid apogee thruster (DMLAT). Despite the ambiguity with respect to the use of engine and motor in these names, all use liquid propellant.
