NASA's Lunar Grounding Challenge seeks static discharge fix

NASA launched the Lunar Grounding Challenge with $150,000 in prizes. It seeks a way to equalize charge between an astronaut (up to -100 kV) and a lander (~100 V) while keeping current below 1 mA, ideally under 0.2 mA.

• The challenge offers $150,000 in rewards
• Astronaut potential reaches -100 kV, lander about 100 V
• Discharge current must stay below 1 mA, ideally 0.2 mA
• Any arc must not contact the suit or astronaut
