Satellite News

Satellites are used for a large number of purposes. Common types include military (spy) and civilian Earth observation satellites, communication satellites, navigation satellites, weather satellites, and research satellites.

NASA scientists conducting an airborne campaign right now in the Arctic to monitor changes in sea ice and ice sheet thickness have a new tool.

A second aircraft -- the King Air B200 - arrived in Kangerlussuaq, Greenland, carrying an instrument that maps the icy surface from more than five miles (8 km) above, providing yet another perspective of Earth's changing polar regions.

The newest addition flew on April 13 to join Operation IceBridge -- a six-year airborne mission to monitor Earth's polar ice. The B200 will target the southeastern portion of the Greenland Ice Sheet, where NASA satellites have shown ice loss.

The flight marks the first trip to Greenland for the aircraft from NASA's Langley Research Center in Hampton, Va. The King Air is carrying the Land Vegetation and Ice Sensor (LVIS) instrument, a laser altimeter that can map large areas of sea ice and ice sheets.

IceBridge data provides a three-dimensional view of the Greenland Ice Sheet that will help predict future contributions to rising seas. A series of science flights designed to increase knowledge of ice sheet processes and sea level rise contributions are scheduled for April 15 through May 9.

Current estimates of sea level rise from Greenland are placed at .5 millimeters annually.

The B200 flights complement sea ice flights by the P-3B aircraft out of NASA's Wallops Flight Facility in Wallops Island, Va. The P-3B has been in Greenland since March 14. Flights were conducted from Thule for the first part of the mission and then out of Kangerlussuaq since April 1.

The P-3B is carrying a suite of instruments including a magnetometer, gravimeter, Airborne Topographic Mapper and camera systems.
