On the concept of a low-cost space system for detecting hazardous celestial bodies

Abstract

We present the concept of a space system for detecting hazardous celestial bodies larger than 100 m 15–30 days before their possible collision with the Earth on the base of a wide-angle telescope with the aperture of 0.75 m and a field of view with a diameter of 7°. A preliminary configuration of a spacecraft using the low-sized Lavochkin Association platform is proposed. Preliminary estimates of the main system parameters are given. The main advantage of the system is a combination of high productivity, penetrating force, moderate technical complexity, and low cost of the implementation.
