In 2013 NASA introduced an asteroid-capture mission called ARM (Asteroid Redirect Mission) which would bring an asteroid to moon's orbit.____________________Sources:The Evolution Of NASA’s Ambitious Asteroid-Capture Mission:https://www.space.com/28963-nasa-asteroid-capture-mission-history.html“NASA's ambitious asteroid-capture mission has changed a lot since the agency officially announced its existence less than two years ago. The original plan, which was revealed in April 2013, called for dragging an intact small space rock into orbit around the moon, where it would be visited by astronauts, perhaps as early as 2021."Animation Of Proposed Asteroid Retrieval Mission Video:https://www.youtube.com/user/VideoFromSpace“NASA's 2014 budget poposes a mission to robotically capture a small near-Earth asteroid and bring it into a stable lunar orbit where astronauts can visit and explore it, a 'stepping stone' to future missions to farther asteroids."Asteroid Retrieval Feasibility Study:https://www.rt.com/usa/158784-nasa-asteroid-landing-mining/ “This report describes the results of a study sponsored by the Keck Institute for Space Studies (KISS) to investigate the feasibility of identifying, robotically capturing, and returning an entire Near-Earth Asteroid (NEA) to the vicinity of the Earth by the middle of the next decade."NASA Aims To Land On, Capture Asteroids Within Next 15 Years:https://www.rt.com/usa/158784-nasa-as...“NASA researchers are at work developing a plan that not only hopes to physically place astronauts on an asteroid for the first time, but also to wrangle a space object and place it in the orbit of the Earth’s moon."Meet The Team At Planetary Resources:https://www.planetaryresources.com/company/#company-intro____________________Follow Trace on twitter: http://twitter.com/tracedominguezFollow Seeker on twitter: http://twitter.com/seekerAnd, subscribe on YouTube too: http://youtube.com/seekerSeeker inspires us to see the world through the lens of science and evokes a sense of curiosity, optimism and adventure.Visit the Seeker website for more science coveragehttps://www.seeker.com/ Learn more about your ad choices.
