NASA SLS Space Launch System Key Ring

The new SLS or Space Launch System is the most powerful rocket system ever built for NASA. It’s thrust is greater than either the Saturn V or Space Shuttle. This super heavy-lift launch vehicle will have the capacity to launch large payloads to low Earth orbit, to the moon and lunar orbit, and then on to asteroids, Mars and other planets in our Solar System. One of the most important payloads is the new Orion spacecraft crew vehicle that will take astronauts on deep space missions.
