From the vantage point of the Terra satellite, the instrument can detect the scarred land that the wildfire, burning north of Tucson, is leaving in its wake.


On the night of June 5, a lightning strike started the Bighorn Fire in the Santa Catalina Mountains north of Tucson, Arizona. Extremely dry vegetation and windy conditions caused the fire to spread quickly. By June 30, the multi-agency incident information system, InciWeb, reported that it had ballooned to more than 114,000 acres and that it was about 45% contained.

NASA’s Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) instrument aboard the Terra satellite imaged some of the burned area on June 29. In this image, vegetation is shown in red and burned areas appear dark gray. It covers an area 20 by 30 miles (33 by 48 kilometers).

Efforts to contain the fire continue with 21 hand crews, 10 helicopters and dozens of fire engines deployed to the area. Smoke impacts to surrounding communities are being carefully monitored.

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 91 meters), ASTER images Earth to map and monitor the changing surface of our planet. It 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 Southern California. The Terra mission is part of NASA’s Science Mission Directorate, Washington.

When volcanoes erupt, ASTER turns its attention to documenting the changes to the landscape as they happen. ASTER is uniquely capable of turning to see areas where volcanoes are erupting in very high resolution (between 15 in the thermal bands – 90 meter spatial resolution in the visible light spectral bands).

As Hawaii’s Kilauea continues to erupt, ASTER continues to monitor the eruption from space. This image from May 6, 2018 shows the sulfur dioxide being released from the volcano in yellow and yellow-green.

Cloud Streets over Timor Sea

July 24, 2016

These “streets of the sky” called cloud streets are long parallel bands of cumulus clouds. On July 15, 2016, the Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite aquired these images of cloud streets off the northern coast of Australia.

Swirls of Ice in the Labrador Sea

July 21, 2016

What first appeared to be a storm wasn’t a low pressure system in the clouds, but a swirling mass of ice in the sea. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra and Aqua satellites acquired views of an ice eddy off the coast of Labrador, Canada, on July 2, 2016.

Caterpillars Take Bite Out of Rhode Island Forests

July 15, 2016

Gypsy moth caterpillars damaged parts of New England’s forests and the damage is extensive enough to be seen from space. The Moderate Imaging Spectroradiomenter on NASA’s Terra satellite captured images of the damage over Rhode Island, Massachussetts and Connecticut during the pests’ population boom in the summer of 2016.

Unusual Dust Off of Chile

July 12, 2016

Large amounts of dust were airborne off the west coast of South America. This is not a typical location dust events such as this one. The Moderate Resolution Imaging Spectroradiometer (MODIS) on NASA’s Terra satellite acquired this image of airborne dust off the coast of Chile, on July 8, 2016.

Studying the Sherpa Fire

July 2, 2016

The Sherpa fire west of Santa Barbara, California was contained before it caused damage to homes or infrastructure. However, it still charred several thousand acres as of June 29. The Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on the Terra satellite acquired an image of the burn scar on June 19, 2016. Read more on NASA’s Earth Observatory.

Does Dust Affect Water Levels of the Caspian Sea

June 10, 2016

Dust storms over the Caspian Sea lead to increased evaporation and a drop in lake level according to new research using observations of dust collected by instruments on several satellites including the Moderate Imaging Spectroradiometer (MODIS ) and the Multi-angle Imaging Spectroradiometer (MISR) on Terra.

Using Clouds to Map Life – A team of researchers are using cloud data from the Moderate Imaging Spectroradiometer (MODIS) on NASA’s Terra Satellite to create detailed maps of cloud cover and variability. The team found that cloud cover could be an indicator and a better predictor of a songbird and flower’s range than temperature and precipitation.

Sierra Nevada Snowpack is Better, But not Normal – Snowpack in the Sierra Nevada mountains dwindled over recent years; however, the winter of 2015-2016 and the strong El Nino provided a thicker and more extensive snowpack. Regardless, snow levels in the Sierra Nevada mountains were still below average. Images from NASA’s Moderate Imaging Spectroradiometer (MODIS) clearly show the difference between years.
