KSC-00pp0883

Lightning field study devices are visible on a Cessna Citation aircraft during flight over Central Florida. The center of the black circle contains one of six field mills, used to measure electric fields, located on the body of the plane. Below the circle is one of several cloud physics probes attached to the plane that measure the size, shape and number of ice and water particles in clouds. The Cessna is being flown into anvil clouds in the KSC area as part of a study to review and possibly modify lightning launch commit criteria. The weather study could lead to improved lightning avoidance rules and fewer launch scrubs for the Space Shuttle and other launch vehicles on the Eastern and Western ranges.; More information about the study can be found in <a href="http://www-pao.ksc.nasa.gov/kscpao/release/2000/56-00.htm">Release No. 56-00</a>
