The purpose of the work is the determining the actual issues and fundamental scientific tasks for solving the problem of preventing catastrophic collisions of space objects with the Earth's surface, determining the methods and ways of observing space invasions. Methods of research - informational and analytical method, methods of theoretical mechanics and space flight mechanics, field observations of space invasions, investigation of properties of traces of invasion by methods of colorimetry, mathematical modeling and computer visualization. The perspective schemes for changing the trajectory falling objects of space debris with the help of the so-called "patrol" spacecraft, which operates in a very low Earth's orbit are chosen. A new way of changing the trajectory of the motion of a space object by means of a shot by some projectile (impactor) from the board of the "patrol" spacecraft is proposed. Estimates of aerodynamic influence on a "patrol" spacecraft moving in three hundred kilometers orbit are obtained. The oscillations of positions, brightness, variations of the temperature of the invasion traces are determined, the appearance of inversion traces in the troposphere, the screw trajectories of invasion are explained. The perspective ways of preventing an asteroid and meteorite threat are chosen. The results of the work can be used to continue the work to identify the threats of space invasions. The proposed method for changing the trajectory of motion of the space debris objects can be used as a method of removal of the space debris objects from the low near-Earth orbits. The obtained estimates of aerodynamic impact on the "patrol" spacecraft can be used in the planning of launches of spacecraft into super low orbits.
