New NASA System to Keep Lightning Off The Launchpad

coondoggie writes to tell us that NASA is building a new system to protect people and equipment on the shuttle launchpad from lightning strikes. "The new structure called a catenary wire system, will be the largest on the space compound and will feature large cables strung between three 594-foot-tall steel and fiberglass towers. Each tower is topped with a fiberglass mast and a series of catenary wires and down conductors designed to divert lightning away from the rocket and service structure. This configuration helps keep the vehicle isolated from dangerous lightning currents, NASA said."

    This configuration helps keep the vehicle isolated from dangerous lightning currents.

    Until it's launched, of course. Unless it will also trail a very, very long grounding wire...
    From: What is NASA's Anvil Rule for Thunderstorms?

    The Shuttle can CAUSE more Lightning: When the space shuttle goes high into the atmosphere, the long plume from the exhaust gives a pathway through which lightning can flow. In addition, the plume will reduce the electrical field necessary to trigger natural lightning.

    This same complex will be used for their next-generation launchers as well

          That is, if they can ever afford to build a "next generation launcher".
