Abstract: | The exploration of our nearest planets will require relaying large amounts of data to Earth for study and evaluation. However, our ability to communicate at interplanetary distances is limited. In this paper, an evaluation is made of our capability to communicate from the vicinity of Mars using the present S-band deep-space network, prospects for enhancing that performance, and limitations beyond which no additional improvement seems feasible. In addition, requirements for real-time television are evaluated and prospects for improving the communication rates by operating at higher microwave frequencies considered. |
