KENNEDY SPACE CENTER, FLA. - In NASA Kennedy Space Center’s Orbiter Processing Facility, bay 3, Don Nielen (left) and Dick Logsdon, both with United Space Alliance, set up equipment to be used for thermography of Discovery’s nose cone. Thermography uses high-intensity light to heat specific areas, which are then immediately scanned with an infrared camera. As the area cools, internal flaws are revealed. Discovery has been identified as the orbiter to fly on mission STS-121.
