NASA’s Space Launch System is an expendable, evolvable super heavy-lift launch-vehicle family for crewed and cargo missions beyond Earth orbit. Every configuration uses a liquid-hydrogen/liquid-oxygen core stage powered by four RS-25 engines and two five-segment solid rocket boosters, with progressively more capable upper stages for the Block 1, Block 1B, and Block 2 variants.
