Project Fire photographic summary and record of reentry phenomena at hyperbolic velocities

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.

Cleanroom air sampler counts, categorizes, and records particle data

Light scattering particle counter monitors particles in a clean room. It categorizes and records the particles according to size and functions simultaneously in three separate areas. The counter uses a transducer head to transform light signals into electric signals.

Scan rate converter for tape recording and playback of TV pictures

Magnetic tape recording and playback equipment converts television pictures, both black and white and color, from one scan rate to another. The equipment indexes color picture frames for retrieval electronically and can be used as a document storage and retrieval medium that is compatible with hard-copy printout machines.
