The U.S. Space Launch System, or SLS, will provide an entirely new capability for human exploration beyond Earth orbit. It also will back up commercial and international partner transportation services to the International Space Station. Designed to be flexible for crew or cargo missions, the SLS will be safe, affordable, and sustainable, to continue America’s journey of discovery from the unique vantage point of space. The SLS will take astronauts farther into space than ever before, while engaging the U.S. aerospace workforce here at home.
