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 6, 2012, NASA landed the rover "Curiosity" on Mars. 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

This mission was the first of a series of missions to Mars that included rovers, and was the first successful lander since the two "Vikings" landed on the red planet in 1976. Although the Soviet Union successfully sent rovers to the Moon as part of the Lunokhod program in the 1970s, its attempts to use rovers in its Mars program failed. In addition to scientific objectives, the "Mars Pathfinder" mission was also a "proof-of-concept" for various technologies, such as airbag-mediated touchdown and automated obstacle avoidance, both later exploited by the Mars Exploration Rover mission. The "Mars Pathfinder" was
