NASA lift vehicle. The Space Launch System is intended to launch the Orion Multi-Purpose Crew Vehicle and other elements towards the Moon, near-Earth asteroids, and one day Mars. The Orion MPCV conducted an unmanned test launch on a Delta IV Heavy rocket in December 2014. The James Webb Space Telescope (JWST) is currently scheduled to launch in May 2020.

On August 27, 2012, "Curiosity" transmitted the first pre-recorded message from the surface of Mars back to Earth, made by Administrator Charlie Bolden: NASA's ongoing investigations include in-depth surveys of Mars
Mars sample-return mission request of NASA and the NSF, declared a MSR campaign its highest priority Flagship Mission for that period. In particular, it endorsed the proposed Mars Astrobiology Explorer-Cacher (MAX-C) mission in a "descoped" (less ambitious) form, although this mission plan was officially cancelled in April 2011. In September 2012, the United States' Mars Program Planning Group endorsed a sample-return after evaluating long-term Mars' plans.

Such effort would require three additional vehicles:
