Telecommunications


Odyssey's telecommunications subsystem is composed of both a radio system operating in the X-band microwave frequency range and a system that operates in the ultra high frequency (UHF) range. It provides communication capability throughout all phases of the mission. The X-band system is used for communications between Earth and the orbiter, while the UHF system is used for communications between Odyssey and any landers present on the Martian surface at any given time.

The telecommunication subsystem weighs 23.9 kilograms (52.7 pounds).
