The United States’ NASA is developing a plan to land humans on Mars by the 2030s. The first step in this mission begins sometime during 2020, when NASA plans to send an unmanned craft into deep space to retrieve an asteroid. The asteroid will be pushed into the moon’s orbit, and studied by astronauts aboard Orion, NASA’s first human spacecraft in a generation. Orion’s crew will return to Earth with samples of the asteroid and their collected data. In addition to broadening America’s space capabilities, this mission will test newly developed technology, such as solar electric propulsion, which uses solar arrays for energy and requires ten times less propellant than the conventional chemical counterpart used for powering space shuttles to orbit.
