Extreme Access

The Extreme Access focus area will expand technology enabling humans and robotic systems to efficiently access, navigate, and explore previously inaccessible lunar surface and subsurface areas. To accomplish this goal, they will consider the needs of robust and sustained surface activities (such as the bulk transport of regolith), ingress, exploration, and egress ofsubsurface voids, hazard detection in all lunar environments and conditions, as well as communicating and navigating with minimal infrastructure and autonomous operations.

Build a community specializing in technology required to access, navigate, and explore surface and subsurface areas on the Moon. Identify areas of interest in technology development, evaluate readiness, and provide a resource for members to gain & share information, network, and discuss technology needs for lunar exploration.


Goals of the LSIC Extreme Access Focus Group (FG) include identifying critical technology gaps that pertain to robotic access, navigation, and exploration of the lunar surface and subsurface, especially previously inaccessible regions and assessing the readiness of systems and components.

LSIC EA Subgroups

We have 4 standing subgroups, and also the potential for ad-hoc subgroups. Each subgroup has a wiki page on the internal LSIC confluence site with meeting notes and additional information.

Standing subgroup descriptions:

  • Communications:
    • Determine the suitability of different communication technologies available for various lunar environments
    • Identify which technology demonstrations are necessary and which are planned to raise the TRL of various technologies
    • Examine current planned mission communication solutions
  • Mobility:
    • Establish current state of mobility technologies being used on missions
    • Identify needs and potential solutions of future missions
    • Produce technology development map for different types of missions, focusing on different types of mobile platforms and conops
  • Position, Navigation, and Timing (PNT):
    • Determine suitability of different PNT technologies for specific environments
    • Evaluate what technology demonstrations will be necessary to raise the TRL of PNT sensors and systems
  • Terrain Relative Navigation (TRN):
    • Collect and share TRN strategies being used on different missions
    • Discuss gaps and needs related to datasets, hardware and software issues, mapping and analysis tools, and terrain rendering tools
