  "account": "NASA is seeking innovative ideas and strategies to tackle the challenge of discharging electric charge from astronauts during extravehicular activities (EVA) on the Moon's South Pole. The problem arises due to tribocharging from walking on the lunar surface and plasma charging from the surrounding plasma, which can build up a substantial negative potential in a spacesuit. In permanently shadowed regions (PSRs), this buildup can be severe due to the lack of ambient ion flux and photoelectron emission. When an astronaut returns to a lander, the extreme voltage difference between the highly negatively-charged suit and the slightly positive lander can trigger an electrostatic discharge, posing risks such as damaging suit layers, electronics, and the suit's oxygen-rich environment, and delivering dangerous shocks to the crew. The Lunar Grounding Challenge, initiated by NASA, offers up to $150,000 in prizes for innovative designs and operational solutions to enable a safe and timely discharge of a suited astronaut under these extreme charge differential conditions before direct interaction with the lander. The challenge opened on October 5, 2026, and submissions are due by January 15, 2027. Further information can be found at https://work.crowdplat.com/challenge/lunar-grounding-challenge.",

This problem is severely compounded when entering lunar shadows and Permanently Shadowed Regions (PSRs).
