Abstract: Aproject of elimination of potentially dangerous asteroid Apophis which April13, 2029 year approaches to Earth at a distance of 36,000 km is considered. The elimination is carried outby means of asteroid disintegration into small fragments as a result of nuclearexplosion, which is produced 133 days before the moment of maximal convergenceof the asteroid Apophis with Earth. In the project, a method of phased timely delivery of nuclearcharge on the surface of the asteroid is proposed. In the first stage, the nuclear charge using carrier rocket “Delta” isdelivered into Earth orbit. In the second stage, the charge using electric rocket is transferredfrom Earth orbit into the orbit of asteroid Apophis and is descended onto itssurface. For implementation of the project, the design of electric rocket ER-7,which uses electric rocket engines type MARS and solar panels based on galliumarsenide is developed. Design of landing capsule, which has a chemical rocketengine and the container in which located the nuclear charge of 6 megaton isdeveloped.
