NASA-linked Lunar Grounding Challenge seeks lunar south pole ESD solutions

The Lunar Grounding Challenge, linked to NASA, is seeking designs and operational solutions for electrostatic discharge (ESD) mitigation at the lunar south pole. The challenge lists 150,000 USD in funding and a milestone on January 15, 2027.

The Lunar Grounding Challenge is linked to NASA and is asking for designs and operational approaches to an ESD mitigation solution at the lunar south pole.

The challenge lists funding of 150,000 USD and a milestone dated January 15, 2027.

The facts list a spacesuit as having negative potential, a stationary lander as having slightly positive electrical potential, and an astronaut as a high voltage capacitor.

Electrostatic discharge is described as being triggered by extreme voltage differential, while the lunar surface is described as lacking a natural charge bleed mechanism.

Tribocharging and plasma charging generate electric charge on a spacesuit. Lunar shadows and Permanently Shadowed Regions (PSRs) compound the charging problem, and rapid discharge risks suit degradation and electrical shocks.

The facts identify electrostatic discharge mitigation as a NASA-linked technical need at the lunar south pole.

Charge can build up on spacesuits through tribocharging and plasma charging, while shadows and Permanently Shadowed Regions (PSRs) compound the problem. Rapid discharge risks suit degradation and electrical shocks, which is relevant to operations involving astronauts, spacesuits, and landers.
