- Аннотация: STARDUST spacecraft was launched on February 7, 1999. STARDUST is the first U.S. space mission dedicated solely to the exploration of a comet, and the first robotic mission designed to return extraterrestrial material from outside the orbit of the Moon. But studying of observational data of the STARDUST Sample Return Capsule’s represent a big interest. At a velocity of 12.8 km/s (assumed to be at an altitude of 125 km) SRC was the fastest ever attempted re-entry of a human made space vehicle. The return trajectory of the SRC is very similar to that of natural cosmic bodies. Entry begins when the spacecraft reorients for SRC release from the spacecraft bus and ends with parachute deployment. In the present report, an analytical model of the atmospheric entry is calculated using the data of actual observations, by selecting the parameters describing rate of deceleration of the body during its hypersonic flight. Model was applied to the observational data of STARDUST Sample Return Capsule (a hypersonic phase). The estimate of mass of SRC obtained using the data of actual observations is quite close to its real value of 45.8 kg.
