Image Caption: Dyess Air Force Base: Abilene, Texas:
Dyess Air Force Base, located near the central Texas city of Abilene, is the home of the 7thBomb Wing and 317th Airlift Groups of the United States Air Force. The base also conducts all initial Air Force combat crew training for the B-1B Lancer aircraft. The main runway is approximately 5 kilometers long, a distance that is necessary to accommodate the large bombers and cargo aircraft at the base. Many of these aircraft are visible in the image, parked in parallel rows on the base tarmac.
Airfields and airports are useful sites for astronauts to hone their technique for using a long camera lens to acquire high-resolution images. The sharp contrast between highly reflective, linear features, such as runways, and darker agricultural fields and undisturbed (vegetated) land allows fine focusing of the cameras. This on-the-job training is crucial for teaching astronauts to obtain not only high-resolution imagery of Earth, but also inspection photographs of the thermal protection tiles on the Space Shuttle during continuing missions to the International Space Station.
