A group of asteroids in space suddenly changed direction and began moving towards Earth. This shocked all astronomers; it happened too quickly. Apparently, some large object appeared in the path of the asteroids, capable of forcing them to change course. But the numbness soon passed, because something had to be done. Such a huge number of incredible-sized stones will not leave even a speck of dust from our planet, but one asteroid was enough there, and there are dozens of them. A suitable rocket was urgently found in Orbiter, equipped with explosives. Launch it and control it so that it flies as far as possible and destroys as many asteroids as possible in the Orbiter.
