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 ...
It was used for the first docking to a space station in the history of space flight, with the Soyuz 10 and Soyuz 11 missions that docked to the Soviet space station Salyut 1 in 1971. [1] [15] The docking system was upgraded in the mid-1980s to allow the docking of 20 ton modules to the Mir space station. [16]
Space Shuttle Atlantis landing after STS-122. Columbia was the first Shuttle to arrive at the SLF via the Shuttle Carrier Aircraft on March 24, 1979. The runway was first used to land a Space Shuttle on February 11, 1984, when Challenger's STS-41-B mission returned to Earth. This also marked the first landing of a spacecraft at its launch site.
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. Airstairs eliminate the need for passengers to use a mobile stairway or jetway to board or exit the aircraft, providing more independence from ground services.
Splashdown is the method of landing a spacecraft by parachute in a body of water. It was used by crewed American space capsules prior to the Space Shuttle program, by the SpaceX Dragon 1 and Dragon 2 capsules and by NASA's Orion Multipurpose Crew Vehicle. It is also possible for the Russian Soyuz spacecraft to land in water, though this is only ...
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 ...
The facility has four 3D printers and an adjacent machine shop with lathes, drill presses, a CNC Router, and other equipment to enable rapid iterative prototyping. The facility also includes an Innovation Space where employees are encouraged to work informally in the upstairs loft. [citation needed] Granular Mechanics and Regolith Operations Lab
