Project Fire was undertaken by the National Aeronautics and Space Administration to measure the total and radiative heating experienced by a blunt body reentering the earth's atmosphere at 11 300 meters per second. This report presents a photographic record of the Fire II spacecraft during its reentry. The photographs were clear enough to establish the times of major events, and they show that adequate-separation was maintained between the reentry package and the spent Antares. This report also identifies operational problems encountered in spacecraft reentry at hyperbolic velocities and presents the solutions satisfactorily employed.
