Authors offer the new method for deliver the asteroid to Earth. That method is cheaper in a lot of times than a conventional method. In our method for braking apparatus and asteroid are used the kinetic energy of apparatus. This energy is used also for charging the apparatus energy storage. The small control parachute allows multiple using the Earth atmosphere for the braking the asteroid without high heating, deliver the asteroid in given point and to avoid the asteroid impact to Earth. In recent years, industry has produced high-temperature fiber and whiskers. The authors examined and proposed the use of high temperature tolerant parachute for atmospheric air braking. Though it is not large, a light parachute decreases asyeroid speed from 11 km/s to 50 m/s and a heat flow by tens times. The parachute surface is opened with backside so that it can emit the heat radiation efficiently to Earth-atmosphere. The temperature of parachute may be about 1000 1300o C. The carbon fiber is able to keep its functionality up to a temperature of 1500 2000o C. There is no conceivable problem to manufacture the parachute from carbon fiber. The proposed new method of braking may be also applied to the old Space Ship as well as to newer spacecraft designs. Key words: Asteroid delivery to Earth, Atmospheric reentry, Space Ships, thermal protection of asteroid and space apparatus, parachute braking.
