Description

The SLS Initial Lift Capability will be designed to carry the Orion Multi-purpose crew vehicle, as well as important cargo, equipment and science experiments to Earth's orbit and support deep space exploration. Besides, the SLS will serve as backup system for transportation services to the International Space Station (ISS). It has a lift capacity for 70 metric tons or 77 tons. The SLS Initial Lift Capability features a core stage, interstage and the Orion multi-purpose crew vehicle along with the Launch Abort System (ALS). The core stage uses RS-25D/E rocket engines derived from the Space Shuttle Main Engines along with two solid rocket boosters (SRBs). At liftoff the rocket has 10 percent more thrust than the Saturn V heavy launch vehicle. The program was delayed with the first launch expected in 2020 but finally to be carried out on November 16 2022. The Artemis I mission landed in the Pacific Ocean on December 11, 2022.
