U.S. Coast Guard sailors sight and attack a submarine at sea.

U.S. Coast Guard cutters at sea. U.S. Coast Guard sailors on cutters in heavy seas. A sailor looks through binoculars from the observation deck. Another sailor looks through binoculars, keeps a watch, and informs the crew of a submarine sighting. The cutters attack and drop shells into the water. Massive underwater explosions. The crew mans and fires the deck gun. A pilot readies his plane. Oil from a leaking submarine floats on the water surface. Cutters at sea. A Coast Guard sailor and a SPARS (Coast Guard Women's Reserve) walk along the New York harbor. The Statue of Liberty in the background. The New York skyline as SPARS march. Voice narration in part by James Cagney and Ginger Rogers.

Formula expressing relation between transmitted and received power and factors affecting Space Communications.

Space Communications and the related problems and developments. Animation: Final formula expressing the relation between power transmitted and power received. Comparison of the distance between Earth and the moon, and Earth and Pluto. Factors effecting Space Communication. Payload factor: Effect of payload weight of a communication equipment, transport of equipment, need for small and light equipment. Limitations in miniaturization of components: Inaccessibility in term of maintenance and service. Depicts longevity of power based on available power sources. Advantages and drawbacks of chemical batteries, solar batteries, nuclear batteries. States methods for reducing power consumption: equipping vehicles with command transponders. Factors effecting Sapce Communication: Spatial environment and equipment used. Example of information required to study the planet Venus: atmospheric composition, surface temperature changes and exact period of rotation. Explains spatial movement and solution for this factor: Placing four equally spaced terrestrial stations around the globe, joint by reliable communication links for continuity and data reception.

Transmission and reception of data, and frequencies and bandwidth considerations in Space Communications.

Space Communications and the related problems and developments. Animation: Additional factors introduces into Space Communications by transmission and reception of data. Frequencies and bandwidths applicable to Space Communications. Factors to be weighed while considering bandwidth: Available power and transmission system required. Narrower bandwidths used to conserve power, they're also less affected by noise interference. Depicts consumption of power by television, spoken word and teletype bandwidths. Telemetry: low bandwidth and power consumption. Explains Telemetry. Theory of Modern Communication and Binary digits or BITS. Depicts information required from outer space like: radio activity level of the moon's surface, abundance of water vapor in the Martian atmosphere, and variation in surface temperature of Mercury. Telemetry utilizes relatively small bandwidth and thus used as preferable mode of communication for research vehicles.

Use of video, and the various Orbiting and Satellite Systems in Space Communications.

Space Communications and the related problems and developments. Animation: Use of video for Space Communications requires highly directive antennas for power economy. Depicts enlargement of capture area of antennas located at terrestrial reception points. Efficiency in signal processing of the receiving equipment increased, to reduce intrinsic noise by reducing temperature of components. A satellite in Earth's orbit for space and terrestrial communications. Explains the Passive Sattelite Relay System using reflecting spheres; Single Orbiting Active Satellite System using line of sight communication, ideal for weather forecasting and mapping; and the sophisticated active Day Period Cry Satellite Orbiting System equipped with transponders.
