NASA’s Space Launch System (SLS) is an advanced, heavy-lift launch vehicle that will provide an entirely new capability for science and human exploration beyond Earth’s orbit. SLS is the first rocket and launch system capable of sending humans, habitats and support systems to deep space. SLS will give the nation a safe, sustainable and versatile means of reaching beyond our current limits and open new doors of discovery from the unique vantage point of deep space. Built on the most powerful and proven propulsion system in the world, SLS reduces the required mission duration, which decreases the mission cost and allows for a faster path to Mars.
