Hearing on ''An Update on the Space Launch System and Orion: Monitoring the Development of the Nation's Deep Space Exploration Capabilities''; Exploration Flight Test-1; Orion and SLS: Traveling Beyond LEO; Conclusion; Index 520 NASA is undertaking a trio of closely-related programs to continue human space exploration beyond low-Earth orbit: the SLS vehicle; the Orion capsule, which will launch atop the SLS and carry astronauts; and the supporting ground systems. As a whole, the efforts represent NASA's largest exploration investment over the next decade, potentially as much as 22 billion, to demonstrate initial capabilities. Beyond 2021, NASA plans to incrementally develop progressively more-capable SLS launch vehicles complemented by Orion capsules and ground systems.
