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.
