To ensure the best coverage of our solar system, MIT Assistant Professor Richard Linares envisions a constellation of "statites" that communicate and work together, only activating the statite in the optimum position to fly by or rendezvous with an interstellar object successfully. Other statites in the constellation can continue to wait for the next ISO to appear.

MIT researchers have devised a framework for deciding which type of mission would be most successful in deflecting an incoming asteroid, taking into account an asteroid’s mass and momentum, its proximity to a gravitational keyhole, and the amount of warning time that scientists have of an impending collision.
