MT. HALEAKALA, MAUI, HAWAII -- Ground-based Electro-Optical Deep Space Surveillance systems are housed in domes like this one at Detachment 3, 20th Space Control Squadron on the island of Maui, Hawaii. Cadets from the United States Air Force Academy are working with the 21st Operations Group to determine if operating parameters for keeping dome shutters open during inclement weather can be expanded.
