Robotic tools and techniques to redirect an asteroid up to 1,000 metric tons in mass into a distant orbit around the moon. Specifically, NASA is eying electric propulsion systems that would be ready to fly within five years. The systems also should include sensors to determine an asteroid's size, shape, mass, spin rate, surface conditions and composition and other characteristics. If the system can double as a way to service satellites in orbit, so much the better.
Proposals for shifting an asteroid's flight path with a robotic spacecraft, called in NASA parlance an "Asteroid Redirection Vehicle."
Systems that could capture and de-spin an asteroid up to 1,000 metric tons in mass. "NASA is interested in evaluating a variety of concepts and supporting technologies for an asteroid capture system, such as deployable and inflatable structures, capture bags, robotic mechanisms, modeling and simulation, telerobotic operations, and other innovative approaches," the agency wrote in its solicitation.
