The Space Launch System ( SLS) is an American super heavy-lift expendable launch vehicle used by NASA. As the primary launch vehicle of the Artemis Moon landing program, SLS is designed to launch the crewed Orion spacecraft on a trans-lunar trajectory. The first SLS launch was the uncrewed Artemis 1, which took place on 16 November 2022.
An SLS machine being used at the Centro de Pesquisas Renato Archer in Brazil.. Selective laser sintering (SLS) is an additive manufacturing (AM) technique that uses a laser as the power and heat source to sinter powdered material (typically nylon or polyamide), aiming the laser automatically at points in space defined by a 3D model, binding the material together to create a solid structure.
Limit state design. Limit State Design ( LSD ), also known as Load And Resistance Factor Design ( LRFD ), refers to a design method used in structural engineering. A limit state is a condition of a structure beyond which it no longer fulfills the relevant design criteria. [1] The condition may refer to a degree of loading or other actions on ...
System-level simulation (SLS) is a collection of practical methods used in the field of systems engineering, in order to simulate, with a computer, the global behavior of large cyber-physical systems. Cyber-physical systems (CPS) are systems composed of physical entities regulated by computational elements (e.g. electronic controllers).
Burn time. 127 s. Propellant. PBAN - APCP. The Space Shuttle Solid Rocket Booster ( SRB) was the first solid-propellant rocket to be used for primary propulsion on a vehicle used for human spaceflight. [1] A pair of these provided 85% of the Space Shuttle 's thrust at liftoff and for the first two minutes of ascent.
LH 2 / LOX. The Space Launch System core stage, or simply core stage, is the main stage of the American Space Launch System (SLS) rocket, built by The Boeing Company in the NASA Michoud Assembly Facility. At 65 m (212 ft) tall and 8.4 m (27.6 ft) in diameter, the core stage contains approximately 987 t (2,177,000 lb) of its liquid hydrogen and ...
The SLS is the main Earth-launch vehicle of the Artemis lunar program, as of March 2021. NASA is required by the U.S. Congress to use SLS Block 1, which will be powerful enough to lift a payload of 95 t (209,000 lb) to low Earth orbit (LEO), and will launch Artemis 1, 2, and 3.
Standard sea-level conditions. Standard sea-level conditions ( SSL ), [1] also known as sea-level standard ( SLS ), defines a set of atmospheric conditions for physical calculations. The term "standard sea level " is used to indicate that values of properties are to be taken to be the same as those standard at sea level, and is done to define ...
