A rocket engine firing. A blue flame is projecting from a bell-shaped nozzle with several pipes wrapped around it. The top of the nozzle is attached to a complex collection of plumbing, with the whole assembly covered in steam and hanging from a ceiling-mounted attachment point. Various pieces of transient hardware are visible in the background.

RS-25, atau dikenal sebagai Space Shuttle Main Engine (SSME) atau Mesin Utama Pesawat Ulang alik, adalah sebuah mesin roket bahan bakar cair kriogenik yang digunakan pada Space Shuttle NASA dan direncanakan akan digunakan pada penggantinya, Space Launch System. Dibangun di Amerika Serikat oleh Rocketdyne, RS-25 membakar hidrogen cair cryogenic & propelan oksigen cair, dengan masing-masing mesin memproduksi 1.859 kN (418.000 lbf) daya dorong di lepas landas.
