NASA’s Space Launch System, or SLS, is a super heavy-lift launch vehicle that provides the foundation for human exploration beyond Earth’s orbit. With its unprecedented power and capabilities, SLS is the only rocket that can send Orion, astronauts, and cargo directly to the Moon on a single mission.

Nasa has been developing a huge rocket called the Space Launch System (SLS) to launch astronauts to the Moon - and eventually Mars. Set to make its debut in early 2022, the SLS is the most powerful launch vehicle built since the 1960s.
