Description Swarms of cooperative small satellites can serve as a relay for critical flight operations, as was proven with the MarCO technology demonstration. By routing planetary communications traffic through a set of cooperating communications relays, the burden on DSN scheduling can be significantly reduced. The use of frequency division (OMSPA) enables all probes communicating through the relay to be received by one DSN antenna, enabling DSN resources to be extended across a greater number of missions. In contrast to a monolithic relay, swarms enable a greater degree of granularity in supporting multiple probes simultaneously. Swarms also provide the usual benefits of multi‑element array reception, namely robustness to single point failures and transmit/receive diversity.
The downside of swarms is the additional complexity in coordinating the multiple elements. Recent advancements in swarm and constellation optimization have made the concept more tractable, and ripe for exploration as a future architecture for the human exploration of Mars. Long round‑trip light times make centralized coordination of swarms difficult, so distributed coordination becomes more critical. Study of these architectures through simulation (e.g. ns‑3) and hardware test platforms (e.g. Software Defined Radio) will enable critical information for architecture selection of future planetary missions.
