This radar image shows the presence of large birds around Launch Pad 39B. The data is being relayed from the avian radars recently set up on the pad. The computer is one of two set up in Firing Room 4 of the Launch Control Center. When birds, especially vultures, are near the shuttle during a launch, impact on a critical area is possible and could cause catastrophic damage to the vehicle. Already proven affective for aviation where threats posed by bird strikes have been a problem, the avian radar, known as Aircraft Birdstrike Avoidance Radar, provides horizontal and vertical scanning and can monitor either launch pad for movement of vultures around them. If data relayed from the avian radar indicates large birds are dangerously close to the vehicle, controllers could hold the countdown. Photo credit: NASA/George Shelton
