NASAs Terra spacecraft shows Luxor, a city in Upper Egypt, along the Nile. It is the site of the ancient Egyptian city of Waset, known to the Greeks as Thebes.

Luxor is a city in Upper Egypt, along the Nile. It is the site of the ancient Egyptian city of Waset, known to the Greeks as Thebes. Luxor is one of the world's greatest open-air museums, with the ruins of the temple complexes of Karnak and Luxor. Immediately across the Nile is the Valley of the Kings, burial place of dozens of Egypt's pharaohs, including King Tutankhamun. The image was acquired October 18, 2017, covers an area of 15.9 by 19.3 kilometers, and is located at 25.7 degrees north, 32.6 degrees east.

With its 14 spectral bands from the visible to the thermal infrared wavelength region and its high spatial resolution of about 50 to 300 feet (15 to 90 meters), ASTER images Earth to map and monitor the changing surface of our planet. ASTER is one of five Earth-observing instruments launched Dec. 18, 1999, on Terra. The instrument was built by Japan's Ministry of Economy, Trade and Industry. A joint U.S./Japan science team is responsible for validation and calibration of the instrument and data products.

The broad spectral coverage and high spectral resolution of ASTER provides scientists in numerous disciplines with critical information for surface mapping and monitoring of dynamic conditions and temporal change. Example applications are monitoring glacial advances and retreats; monitoring potentially active volcanoes; identifying crop stress; determining cloud morphology and physical properties; wetlands evaluation; thermal pollution monitoring; coral reef degradation; surface temperature mapping of soils and geology; and measuring surface heat balance.

The U.S. science team is located at NASA's Jet Propulsion Laboratory in Pasadena, Calif. The Terra mission is part of NASA's Science Mission Directorate, Washington.
