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 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 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 liquid ...
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. [160] [161] [162] Starting in 2028, Block 1B is intended to debut the Exploration Upper Stage (EUS) and launch the notional Artemis 4–7.
Configurations of the Space Launch System – Block 1 with the ICPS, Block 1B with the EUS, and Block 2 with upgraded boosters and larger payload fairing. As of January 2022 [update] , the Space Launch System (SLS) – a Shuttle-derived , super heavy-lift expendable launch vehicle – has conducted one successful launch, and a further four have ...
The first versions (Blocks 1 and 1B) of the Space Launch System (SLS) are planned to use a pair of five-segment Solid Rocket Boosters (SRBs), which were developed from the four-segment SRBs used for the Shuttle. Modifications for the SLS included the addition of a center booster segment, new avionics, and new insulation which eliminates the ...
Artemis 2 (officially Artemis II) [4] is a scheduled mission of the NASA -led Artemis program. It will use the second launch of the Space Launch System (SLS) and include the first crewed mission of the Orion spacecraft. The mission is scheduled for no earlier than September 2025. [1] Four astronauts will perform a flyby of the Moon and return ...
The SLS, similar to the original Ares V concept, is powered by four RS-25 engines and two five-segment SRBs. Its Block 1 configuration can lift approximately 209,000 pounds (95 t) to LEO. The Block 1B configuration will add the Exploration Upper Stage, powered by four RL10 engines, to increase payload capacity. An eventual Block 2 variant will ...
