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.
Sodium laureth sulfate ( SLES ), an accepted contraction of sodium lauryl ether sulfate ( SLES ), also called sodium alkylethersulfate, is an anionic detergent and surfactant found in many personal care products ( soaps, shampoos, toothpaste, etc.) and for industrial uses. SLES is an inexpensive and very effective foaming agent. [1]
The Space Launch System (SLS) SRBs, adapted from the shuttle, surpassed it as the most powerful solid rocket motors ever flown, after the launch of the Artemis 1 mission in 2022. [3] [4] Each Space Shuttle SRB provided a maximum 14.7 MN (3,300,000 lbf ) thrust, [5] roughly double the most powerful single- combustion chamber liquid-propellant ...
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 ...
Shit life syndrome (SLS) is a phrase used by physicians in the United Kingdom and the United States for the effect that a variety of poverty or abuse-induced disorders can have on patients. History [ edit ]
Sodium dodecyl sulfate ( SDS) or sodium lauryl sulfate ( SLS ), sometimes written sodium laurilsulfate, is an organic compound with the formula CH3(CH2)11OSO3Na and structure H 3 C − (CH 2) 11−O− S (=O) 2−O−Na+. It is an anionic surfactant used in many cleaning and hygiene products. This compound is the sodium salt of the 12-carbon ...
