The sites included Naval Air Station Bermuda, Lajes Air Base in Terceira island, Azores, Portugal, Zaragoza Air Base in Spain, Morón Air Base in Spain, and Istres Air Base in France. [11] All sites have runways of sufficient length to support the landing of a Space Shuttle, and included personnel from NASA as well as equipment to aid a space ...
Dog-leg (stairs) A dog-leg is a configuration of stairs between two floors of a building, often a domestic building, in which a flight of stairs ascends to a quarter-landing before turning at a right angle and continuing upwards. [1] The flights do not have to be equal, and frequently are not. Structurally, the flights of a dog-leg stair are ...
t. e. SpaceX has privately funded the development of orbital launch systems that can be reused many times, similar to the reusability of aircraft. SpaceX has developed technologies over the last decade to facilitate full and rapid reuse of space launch vehicles. The project's long-term objectives include returning a launch vehicle first stage ...
Starship HLS. Starship HLS (Human Landing System) [a] is a lunar lander variant of the Starship spacecraft that is slated to transfer astronauts from a lunar orbit to the surface of the Moon and back.

A floating launch vehicle operations platform is a marine vessel used for launch or landing operations of an orbital launch vehicle by a launch service provider: putting satellites into orbit around Earth or another celestial body, or recovering first-stage boosters from orbital-class flights by ...
An airstair is a set of steps built into an aircraft so that passengers may board and alight the aircraft. The stairs are often built into a clamshell-style door on the aircraft.

t. e. A reusable launch vehicle has parts that can be recovered and reflown, while carrying payloads from the surface to outer space. Rocket stages are the most common launch vehicle parts aimed for reuse. Smaller parts such as rocket engines and boosters can also be reused, though reusable spacecraft may be launched on top of an expendable ...
