LOX / LH 2. 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 ...
The Interim Cryogenic Propulsion Stage (ICPS) is the upper stage of SLS Block 1, and first flew on Artemis 1. It is planned to fly again on Artemis 2 and 3 with its last flight on SLS being for Artemis 3. It is a stretched and human-rated Delta IV 16 ft (5 m) Delta Cryogenic Second Stage powered by a single RL10 engine.
Interim Cryogenic Propulsion Stage. The Interim Cryogenic Propulsion Stage, a minimally modified 5-meter DCSS, is used as the upper stage of the Space Launch System Block 1. The ICPS for Artemis I was mated to the SLS launch stack on July 6, 2021. Artemis 1 was launched on November 16, 2022, at 06:47:44 UTC (01:47:44 EST).
The RL10 is a liquid-fuel cryogenic rocket engine built in the United States by Aerojet Rocketdyne that burns cryogenic liquid hydrogen and liquid oxygen propellants. Modern versions produce up to 110 kN (24,729 lb f) of thrust per engine in vacuum. Three RL10 versions are in production for the Centaur upper stage of the Atlas V and the DCSS of ...
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 ...
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 core stage is then stacked and is supported by the boosters. The interstage and upper stage are stacked atop the core, and the Orion spacecraft is then stacked onto the upper stage. The Interim Cryogenic Propulsion Stage was the first part of the SLS to be delivered to the Kennedy Space Center in July 2017.
This will be the final mission using SLS Block 1, the design used for the first three missions. Afterward, from Artemis 4 until Artemis 8 , missions will use SLS Block 1B , with a more capable Exploration Upper Stage , and a cargo hold to transport other payloads.
