RETURN CAPSULE

Basic state:• RC braking in atmosphere of the Earth performs only by aerobraking without

use of parachute system which as has shown world experience, can fail;• Applied form of the return capsule which aerodynamic characteristics are well

known;• RC landing performs on testing area "Sary-Shagan" which is equipped by

necessary measuring instruments for definition of a landing point of RC which do not have active instruments such as a radio beacon.
