Future missions are currently being proposed / designed with existing (or moderately inproved) Space-to-Earth communication capabilities in mind. Optical communications technology offers the potential of a dramatic increase in data-rates, specifically in the down-link of science data, thereby allowing for a substantial increase in science return.Direct detection technology using pulse position modulation (PPM) is regarded as the preferred solution for "deep space" optical links.

The emergence of the classical world from quantum theory, and especially of a consensus among different observers, is a long-standing problem for the foundations of quantum theory. Using recent advances in multipartite quantum information theory, we shed light on these problems. Besides their interest for fundamental physics, they are related to quantum sensing and metrology using a quantum-network of stations, a situation of interest for the potential use of quantum-based measurement probes for exploring space and the Universe.

The reception performances of the Deep Space Ground Stations is limited by the noise generated in the front end. Any reduction of this noise will allow to increase the data transmitted or to reduce the required mass and power on the spacecraft transmitter.X band is presently used for the telemetry of all deep space missions and will still be the preferred frequency band for future Mars exploration missions. The existing feed and LNA systems have been designed separately. Therefore, the feed system is operated at room temperature while the LNA is operated at 12 K.
