The "Lotus" dust mitigation coating is a new technology that is currently being developed and tested, at NASA Goddard
Space Flight Center (GSFC), as a countermeasure for addressing dust accumulation issues for long-duration human
space exploration. This coating sheds dust particles utilizing anti-contamination and self-cleaning properties that
minimize dust accumulation on spacecraft surfaces. Shedding of dust particles is accomplished by reducing the surface
energy and the amount of surface available for attachment. The Lotus coating is designed to preserve optimal long-term
performance of critical spacecraft surfaces and systems, while minimizing and/or eliminating dust accumulation. NASA
is exceedingly interested in simplistic and innovative ways to mitigate dust accumulation while minimizing the impact to
spacecraft mass and power requirements. Preliminary research and development indicates that the Lotus Coating has the
potential to be a viable passive tool for mitigating dust on: radiator surfaces, solar array panels, habitation airlock walls,
mechanism shields, astronaut EVA suits, and astronaut visors exterior coating.
