Description

The SLS Evolved Lift Capability will be designed to carry bulky and heavyweight payloads, 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 130 metric tons or 143 tons. The SLS Evolved Lift Capability features a core stage, upper stage and the cargo fairing. The core stage uses RS-25D/E rocket engines derived from the Space Shuttle Main Engines along with two solid rocket boosters (SRBs). The upper stage is equipped with the J-2X rocket engine. At liftoff the rocket has 20 percent more thrust than the Saturn V heavy launch vehicle. The program was delayed with the first launch expected in 2020. As of 2024, the first launch is planned for 2030 or later.
