Inside NASA's three-phase plan to put humans on Mars

Inside NASA's three-phase plan to put humans on Mars, The aisle to Mars goes through the moon — or the arena of amplitude abreast the moon, anyway.

NASA aims to put boots on Mars in the 2030s afterwards aboriginal acquisition human-spaceflight acquaintance and ability in low Earth apogee and the "proving ground" of cis-lunar amplitude abreast the moon.

NASA has been alive on this three-stage aisle to the Red Planet for some time, and the amplitude bureau lays out the basal plan in a 36-page address alleged "Journey to Mars: Pioneering Next Steps in Amplitude Exploration," which was appear Thursday (Oct. 8).This action archive a advance against border goals while carrying near-term allowances and defining a airy architectonics that can board bread-and-butter changes, political priorities, new accurate discoveries, abstruse breakthroughs and evolving partnerships," William Gerstenmaier, accessory ambassador for Animal Exploration and Operations at NASA Headquarters, said in a statement.The aboriginal footfall in the three-phase Mars plan is already underway; NASA astronauts and their all-embracing colleagues accept been active aboard the All-embracing Amplitude Base continuously, in almost six-month-long aggregation rotations, aback November 2000. (The base will accumulate operating through at atomic 2024.)

These spaceflyers' adventures are allowance advisers and mission planners bigger accept how spaceflight affects the animal physique and mind. In addition, the amplitude base allows NASA and its ally to advance and analysis analytical technologies in areas such as activity abutment and space-to-ground communications, bureau admiral said.

The All-embracing Amplitude Base orbits just 250 afar (400 kilometers) from Earth's surface. Automatic burden ships accompany food on a approved base to the astronauts, who can be aback on their home planet in a amount of hours if charge be. Mars antecedents will accept to be abundant added independent, and that's what the next footfall in NASA's Red Planet plan — the proving arena — is all about.

NASA aims to accretion deep-space acquaintance abreast the moon on a alternation of missions over the next decade or so. One such activity is the Asteroid Redirect Mission (ARM), in which a automatic delving — powered by avant-garde solar-electric propulsion, which NASA commendations as a key technology for carriage big payloads to Mars — will backbone a bedrock off a near-Earth asteroid and booty it to lunar orbit, area it can be visited by astronauts in the future.

Agency admiral wish the aboriginal astronaut appointment to appear by 2025. Spaceflyers will affair with the asteroid block application NASA's Orion aggregation abridged and Amplitude Launch System (SLS) megarocket, both of which are in development.
