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
Mars sample-return mission complexity and technical problems. One mission concept (provisionally named simply Mars Sample-Return) was originally considered by NASA's Mars Exploration Program to return samples by 2008, but was cancelled following a review of the program. A NASA-ESA concept mission was aborted in 2012. The United States' Mars Exploration Program, formed after "Mars Observer" failure in September 1992, supported a Mars sample-return. One example of a mission architecture was the "Groundbreaking Mars Sample-Return" by MacPhereson in the early 2000s. In early 2011, the National Research Council's Planetary Science Decadal Survey, which laid out mission planning priorities for the period 2013–2022 at the
