Jamestown, located on Jamestown Island in the Virginia Colony, was founded
on May 14, 1607. It is commonly regarded as the first permanent English
settlement in what is now the United States, following several earlier
failed attempts. It was founded by the Virginia Company, headquartered in
London. The location at Jamestown Island was selected primarily because it
offered a favorable strategic defensive position against other European
forces which might approach by water. However, the colonists soon
discovered that the swampy and isolated site was plagued by mosquitoes and
tidal river water unsuitable for drinking, and offered limited
opportunities for hunting and little space for farming. The area was also
inhabited by Native Americans. What became known as the Starving Time in
the
Virginia Colony occurred during the winter of 1609–10. Only 60 of 214
English colonists survived. Throughout the 17th century, Jamestown was the
capital of the Virginia Colony. On October 20, 1698, the statehouse
(capitol building) in Jamestown burned for the fourth time. In 1699, the
capital of the Virginia Colony was officially relocated to Williamsburg,
and the old town of Jamestown disappeared.

With its 14 spectral bands from the visible to the thermal infrared
wavelength region and its high spatial resolution of 15 to 90 meters
(about 50 to 300 feet), ASTER images Earth to map and monitor the changing
surface of our planet. ASTER is one of five Earth-observing instruments
launched December 18, 1999, on NASA's Terra satellite. 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 the 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,
Pasadena, Calif. The Terra mission is part of NASA's Science Mission
Directorate.
