Submission + - NASA's ARM will take a boulder from an asteroid and take it to lunar orbit (examiner.com)
MarkWhittington writes: NASA announced more details of its controversial asteroid redirect mission. The space agency has chosen to not snag an asteroid in deep space and move it to a retrograde orbit around the moon. Instead, an uncrewed spacecraft with a solar electric propulsion system will snag a boulder off of a larger asteroid and bring it to lunar orbit for an Orion spacecraft to visit.
