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 ...
List of Space Launch System launches. As of January 2022, the Space Launch System (SLS) – a Shuttle-derived, super heavy-lift expendable launch vehicle – has conducted one successful launch, and a further four have been officially scheduled. [1] All flights on the current launch manifest are for the Artemis program, a human spaceflight ...
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.
The Space Shuttle SRBs were the most powerful solid rocket motors to ever launch humans. [2] 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.
The core stage originated in 2011, when the architecture of the Space Launch System as a whole was defined. In the aftermath of the end of the Space Shuttle program and the cancellation of its prospective replacement the Constellation program, the SLS emerged, a super-heavy lift launch vehicle intended for human spaceflight to the Moon. [3] The core stage is the first newly-developed stage of ...
IRIS-T SLS, IRIS-T SLM, IRIS-T SLX, NASAMS-3. The IRIS-T (infrared imaging system tail/thrust vector-controlled) is a medium range infrared homing air-to-air missile available in both air-to-air and ground defence surface-to-air variants. It also is called AIM-2000.
The Exploration Upper Stage (EUS) is a rocket stage under development that will be used for future flights of NASA 's Space Launch System (SLS). Used on SLS Block 1B and Block 2, it will replace the SLS Block 1's Interim Cryogenic Propulsion Stage. The stage will be powered by four RL10C-3 engines burning liquid oxygen and liquid hydrogen to ...
The Delta Cryogenic Second Stage ( DCSS) is a family of cryogenic rocket stages used on the Delta III and Delta IV rockets, and on the Space Launch System Block 1. The stage consists of a cylindrical liquid hydrogen (LH 2) tank structurally separated from an oblate spheroid liquid oxygen (LOX) tank. The LH 2 tank cylinder carries payload launch ...
