Charge dissociation needles

Background
While static charge buildup is a familiar phenomenon, on water-based planets it is seldom a major concern in everyday situations. Without an infinite sea of conductivity below, static charge becomes an important variable in movement and electrical system design.

In the absence of a charge sink the human body can accumulate up to 20 kV [1], potentially arcing 0.67 cm [2] on Earth. On Ammon, atmospheric conductivity varies wildly based on airborne metal constituents. In areas of high concentrations arcing has been observed up to 3 meters, though in theory arcs could travel much farther.

Charges are dissociated quickly nearby any liquid bodies, but can build up over long transits on dry terrain. Static buildup arcs can damage instruments and equipment, so a two-pronged strategy was implemented to minimize this chance. Along with a common ground lattice built around the facility, all EVA suits are outfitted with charge-bleeding needles. These needles act as miniature lightning rods, allowing excess electrons to escape into the atmosphere. Needles are also installed on all remote monitoring equipment that may be charge-sensitive.

Physical specifications
Needles are made from tungsten wire 2 cm long and 2 μm in diameter which is sharpened to a point. Four needles are affixed to each suit at the feet and shoulders. The needle tips are shielded by a small band to prevent unwanted piercing.

Ecological effects
Though the rate of discharge is calculated to be unnoticeable, a daily swarm of Cartcrabs has been found after installing needles on sensor banks near Odessa Lake. Fencing has been installed to maintain sensor integrity, but the swarm still congregates around the perimeter. Our voltmeters are yet unable to detect the charge dumping at any distance.
