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.
