NASA’s Human Architecture Team (HAT) has been studying the feasibility of human exploration missions to the moons of Mars as an intermediate step toward the eventual Mars surface missions. Human missions to Mars’ moons would result in the development and operation of new technologies, systems, and ops concepts, many of which will be required for an eventual Mars surface missions, without the added complexity and risk associated with a Mars descent, ascent, and long-duration surface systems and operations.

The opportunity to perform low-latency teleoperation (LLT) of robotic Mars surface system could provide significant benefits not only for scientific exploration purposes, but also in the scouting and preparation of landing sites in advance of human surface missions. Although the Mars moons of Phobos and Deimos differ significantly from each other in respect to latitudes, duration, and frequency with which line-of-sight to Mars is achievable, both moons offer frequent and operationally useful period of time and latitudes within which low-latency teleoperations of Mars surface assets could be performed such as the selection of landing sites or use of communication relays. Low-latency teleoperations may also include collection and launch of Mars samples into Mars orbit for retrieval and return as part of a human mission to Mars’ moons.
