NASA plans to tame asteroid

NASA is developing a first-ever mission to identify, capture and redirect a near-Earth asteroid to a stable orbit around the moon, where astronauts will explore it in the 2020s, returning with samples.

This Asteroid Redirect Mission (ARM) is part of NASA’s plan to advance the new technologies and spaceflight experience needed for humans to pioneer Mars in the 2030s.
