Date 8/21/00
Description The Arctic Ocean has been mapped in an unprecedented manner by scientists at NASA's Jet Propulsion Laboratory (JPL), Pasadena, Calif. Using advanced radar that sees through all weather conditions, researchers will now be able to determine how the Earth's warming may be changing the sea ice cover. Sea ice in the polar region is a large barometer of global climate conditions. The mission is a joint project between JPL and the Alaska Synthetic Aperture Radar Facility, University of Alaska, Fairbanks. JPL manages the Sea Ice Thickness Derived from High Resolution Radar Imagery project for NASA's Earth Science Enterprise, Washington, DC. The Earth Science Enterprise is dedicated to studying how natural and human-induced change affects our global environment.

Date 8/21/00
Description Scientists at NASA's Jet Propulsion Laboratory (JPL) have used high resolution radar to see, for the first time ever, the development of the Arctic sea ice cover. The images show a comparison of ice growth during the Arctic winter. The two images are separated by nine days. Both images represent an area located in the Baufort Sea, north of the Alaskan coast. This radar view covers an area of 96 by 128 kilometers (60 by 80 miles). The brighter features are older thicker ice and the darker areas show young, recently formed ice. The earlier image is shown on the left. Within the nine-day span, large and extensive cracks in the ice cover have formed due to ice movement. These cracks expose the open ocean to the cold, frigid atmosphere where sea ice grows rapidly and thickens. Formation of sea ice in the Arctic Ocean affects the heat balance in the global atmosphere and ocean. The mission is a joint project between JPL and the Alaska Synthetic Aperture Radar Facility, University of Alaska, Fairbanks. JPL manages the Sea Ice Thickness Derived from High Resolution Radar Imagery project for NASA's Earth Science Enterprise, Washington, DC.

Date 6/22/95
Description This radar image of the Midland/Odessa region of West Texas, demonstrates an experimental technique, called ScanSAR, that allows scientists to rapidly image large areas of the Earth's surface. The large image covers an area 245 kilometers by 225 kilometers (152 miles by 139 miles). It was obtained by the Spaceborne Imaging Radar-C/X-Band Synthetic Aperture Radar (SIR- C/X-SAR) flying aboard the space shuttle Endeavour on October 5, 1994. The smaller inset image is a standard SIR-C image showing a portion of the same area, 100 kilometers by 57 kilometers (62 miles by 35 miles) and was taken during the first flight of SIR-C on April 14, 1994. The bright spots on the right side of the image are the cities of Odessa (left) and Midland (right), Texas. The Pecos River runs from the top center to the bottom center of the image. Along the left side of the image are, from top to bottom, parts of the Guadalupe, Davis and Santiago Mountains. North is toward the upper right. Unlike conventional radar imaging, in which a radar continuously illuminates a single ground swath as the space shuttle passes over the terrain, a Scansar radar illuminates several adjacent ground swaths almost simultaneously, by "scanning" the radar beam across a large area in a rapid sequence. The adjacent swaths, typically about 50 km (31 miles) wide, are then merged during ground processing to produce a single large scene. Illumination for this L-band scene is from the top of the image. The beams were scanned from the top of the scene to the bottom, as the shuttle flew from left to right. This scene was acquired in about 30 seconds. A normal SIR- C image is acquired in about 13 seconds. The ScanSAR mode will likely be used on future radar sensors to construct regional and possibly global radar images and topographic maps. The ScanSAR processor is being designed for 1996 implementation at NASA's Alaska SAR Facility, located at the University of Alaska Fairbanks, and will produce digital images from the forthcoming Canadian RADARSAT satellite. Spaceborne Imaging Radar-C and X-band Synthetic Aperture Radar (SIR-C/X-SAR) is part of NASA's Mission to Planet Earth. The radars illuminate Earth with microwaves, allowing detailed observations at any time, regardless of weather or sunlight conditions. SIR-C/X-SAR uses three microwave wavelengths: L-band (24 cm), C-band (6 cm) and X- band (3 cm). The multi-frequency data will be used by the international scientific community to better understand the global environment and how it is changing. The SIR-C/X-SAR data, complemented by aircraft and ground studies, will give scientists clearer insights into those environmental changes which are caused by nature and those changes which are induced by human activity. SIR-C was developed by NASA's Jet Propulsion Laboratory. X-SAR was developed by the Dornier and Alenia Spazio companies for the German space agency, Deutsche Agentur fuer Raumfahrtangelegenheiten (DARA), and the Italian space agency, Agenzia Spaziale Italiana (ASI), with the Deutsche Forschungsanstalt fuer Luft und Raumfahrt e.v.(DLR), the major partner in science, operations, and data processing of X-SAR. #####
Alaskan Glacier Quakes
title Alaskan Glacier Quakes
date 08.02.2003
description NASA and United States Geological Survey (USGS) scientists found that retreating glaciers in southern Alaska may be opening the way for future earthquakes. The study examined the likelihood of increased earthquake activity in southern Alaska as a result of rapidly melting glaciers. As glaciers melt they lighten the load on the Earth's crust. Tectonic plates, that are mobile pieces of the Earth's crust, can then move more freely, which increases the probability of earthquakes occurring in this region.
Icy Comet NEAT
title Icy Comet NEAT
date 05.07.2004
description This image of Comet C/2001 Q4 (NEAT) was taken at the WIYN 0.9-meter telescope at Kitt Peak National Observatory near Tucson, AZ, on May 7, 2004. The image was taken with the Mosaic I camera, which has a one-square degree field of view, or about five times the size of the Moon. Even with this large field, only the comet's coma and the inner portion of its tail are visible. This color image was assembled by combining images taken through blue, green and red filters. A small star cluster (C0736-105, or Melotte 72) is visible in the lower right of the image, between the head of the comet and the bright red star in the lower-right corner. Comet C/2001 Q4 (NEAT) was discovered on August 24, 2001, by the Near Earth Asteroid Tracking (NEAT) system operated by NASA's Jet Propulsion Laboratory, Pasadena, CA. *Image Credit*: T.

Title Satcom, Communication Satellite
Full Description RCA engineer, Joel Bacher, adjusts a propulsion thruster on a communication satellite. The thrusters were designed to enable the spacecraft to maintain correct altitude control after it had achieved a 22,000-mile synchronous orbit over Earth. The satellite shown is an RCA Satcom domestic communication satellite that was launched December 13, 1975. The satellite was built by RCA Global Communication, Inc. and RCA Alaska Communications, Inc. This domestic communication satellite spurred the cable television industry to unprecedented heights with the assistance of a company known as Home Box Office (HBO). Cable television networks relay signals to ground-based stations using satellites. This allowed cable television to enter into the suburban and metropolitan markets, thus causing HBO to accumulate 1.6 million subscribers by the end of 1977.

2007 Arctic Sea Ice from AMS …
Title 2007 Arctic Sea Ice from AMSR-E with Alaska in Foreground
Abstract Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is semi-permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. The sea ice cover reaches its minimum extent at the end of each summer and the remaining ice is called the perennial ice cover. The 2007 Arctic summer sea ice has reached the lowest extent of perennial ice cover on record - nearly 25% less than the previous low set in 2005. The area of the perennial ice has been steadily decreasing since the satellite record began in 1979, at a rate of about 10% per decade. But the 2007 minimum, reached on September 14, is far below the previous record made in 2005 and is about 38% lower than the climatological average. Such a dramatic loss has implications for ecology, climate and industry. The AMSR-E instrument on the Aqua satellite acquires high resolution measurements of the 89 GHz brightness temperature near the poles. Because this is a passive microwave sensor which is not so sensitive to atmospheric effects, this sensor is able to observe the entire polar region every day, even through clouds and snowfall. This animation progresses at a rate of six frames per day from January 1, 2007 through the minimum extent which occurred on September 14, 2007. The false color of the sea ice, derived from the AMSR-E 6.25 km 89 GHz brightness temperature, highlights the fissures or divergence areas in the sea ice cover by warm brightness temperatures (in blue) while cold brightness temperatures, shown in brighter white, represent consolidated sea ice. The sea ice edge is defined by the 15% ice concentration contour in the three-day moving average of the AMSR-E 12.5 km sea ice concentration data while ice extent is the sum of all pixels with at least 15% ice. An image of the sea ice on September 14, 2007 is included below, along with a corresponding image from September 21, 2005 showing the previous minimum sea ice extent.
