NASA Landsat's Thermal Infrared Sensor Arrives at Orbital

A new NASA satellite instrument that makes a quantum leap forward in detector technology has arrived at Orbital Sciences Corp. in Gilbert, Ariz. There it will be integrated into the next Landsat satellite, the Landsat Data Continuity Mission (LDCM). The Thermal Infrared Sensor (TIRS) will take the Earth's temperature with a new technology that applies quantum physics to detect heat. The engineering team at NASA's Goddard Space Flight Center in Greenbelt, Md., completed TIRS on an accelerated schedule, going from plans on paper to building the instrument in an unprecedented 43 months.

Landsat image maps aid fire recovery efforts

NASA satellite images regularly map active fires around the world. Once a fire is out, satellite data and maps are also used by scientists to measure and protect the scorched land, and have played an important role in streamlining fire recovery efforts. The Remote Sensing Applications Center (RSAC), operated by the U.S. Department of Agriculture Forest Service, and other national agencies that specialize in fire recovery use Landsat 5 and 7 satellite data to observe vegetation, water and soil changes after a fire.

Landsat Satellites Track Continued Missouri River Flooding

Flooding along the Missouri River continues as shown in recent Landsat satellite images of the Nebraska and Iowa border. Heavy rains and snowmelt have caused the river to remain above flood stage for an extended period.

A Landsat 5 image of the area from May 5, 2011 shows normal flow. In contrast, a Landsat 7 image from July 17 depicts flood conditions in the same location.

A national overview map of streamflow provided by U.S. Geological Survey (USGS) WaterWatch graphically portrays the immense geographic extent of flooding in the Missouri River basin.

Tornado Tracks Seen from Space

Tornado tracks from last week's powerful oubreak of events in the southern USA are visible in data from NASA's Aqua satellite and the Landsat satellite. A pale green swath in the above Landsat image from 28th April 2011 reveals the path of a tornado outside Griffin, Georgia, across lightly populated farmland. Bright coloured spots are buildings, some close to the path of the storm.
The town of Griffin, shown on the far right, is the nearest community to the storm track in this area. Credit: NASA , Jesse Allen and Robert Simmon, using USGS Landsat data.
