LSIC | VSAT (May Special Monthly Meeting)
VSATs and Dust Mitigation & Extreme Environments
Dust• Optical effects (obscuration and scattering) + abrasion
effects (issue for mechanisms)• Smallest particles of dust will be the most difficult to
mitigate (though fortunately, they block the least sunlight)
• Power holds us back from landing pad development
EE• 5-6 locations, site has not been selected yet, so we can’t
plan tech for the specific location• In addition to dust, thermal fatigue is also an issue• Initial development means tech may fly twice, then we
learn the environment, tech could evolve rapidly once we get there
E&C Workshop on August 20th , 2021
• Save the date : August 20th, 2 PM - 4:30 PM, Eastern• An extended monthly meeting in lieu of regular meeting.• Workshop Theme: High-TRL Technologies for initial infrastructure development and LLP.• Tentative Agenda:
- NASA E&C Roadmap.- Break-out sessions:
High-TRL technology for initial infrastructure development Power needs for E&C
- Panel discussion on Landing and Launch Pads (LLP)
Your participation will help shape these activities. More information will be shared in the coming weeks.

Dust Mitigation Focus Group Goal
Objectives• Build a diverse community specializing in dust mitigation, including creation of subgroups
focused on specific dust mitigation technology areas• Evaluate specific dust mitigation technology areas for dust mitigation development,
testing/maturation capabilities, and gaps • Provide community recommendations and guides to NASA and broader community to
encourage technology investments and how it can be included in future missions

Lunar dust is a major challenge to robotic and human systems that impacts our ability to enable asustainable presence on the Moon.The goal of the Dust Mitigation focus group is to build a broad and diverse community of lunar andtechnology experts interested in identifying and developing solutions that minimizes the impact andhazard of lunar dust on robotic and human systems. In order to enable a sustainable exploration ofthe Moon, the focus group will identify needs and gaps in dust mitigation, provide recommendationsto foster development, and fielding that technology on future missions.

LSIC | Surface Power - Dust Mitigation Considerations/Needs
July 22-23, 12:00-5:00 pm ETDay 1: Context and DemandDay 2: Deeper Technical Discussions
The challenge of delivering power across the lunar surface is exceptional. The absence of infrastructure, operations in permanently shadowed regions, and unique aspects of the lunar environment provide a potential niche for power beaming solutions. In this LSIC workshop, we will explore the role of wireless power transfer, or power beaming, to deliver power on the lunar surface.
Day one of the workshop will engage a broad audience through content covering context and demand as well as an overview of powerbreaming, with time for small group break-out discussions on power beaming use-cases. This will both inform the lunar community of the scope of what is possible with power beaming, as well as provide power beaming experts an opportunity to engage with lunar experts for a wholistic understanding.
Day two will delve deeper into technical talks and discussions, with plenary talks on power beaming technologies recently funded by NASA, a panel discussion, “challenges and critical steps to advance power beaming,” and technically-focused breakout sessions.
We encourage participation from all stakeholders, and will provide opportunities for networking and forming partnerships to pursue opportunities in power beaming, such as the pending second phase of the Watts on the Moon Challenge.

LSIC | Workshop Power Beaming for the Lunar Surface
- Inventory of potential lunar surface power users and needs- The information you provide will shape our feedback to NASA, which
can directly influence future solicitations and the direction of the field.
LSIC | Surface Power User Survey
Responses will be anonymized, and can be updated on Confluence as technologies develop
https://forms.gle/yhvxAv3xoYKMAU587
- NASA recently requested feedback on power demands for 50’s to 100’s kW; short window to respond
