Two recent images from the Landsat 8 satellite compare land conditions in the vicinity of Yosemite National Park, California, before (August 15) and during the Rim Fire (August 31). Started on August 17, the Rim Fire had burned over 219,000 acres by August 31 (an area nearly 15 times the size of Manhattan Island). Both images are false-colored using bands 6, 5, 4 to allow identification of critical vegetation and fuels information that will help firefighters and emergency managers. In the images fire appears bright red, vegetation is green, smoke is blue, clouds are white, and bare ground is tan-colored.

For more information, about Landsat imagery of the Rim Fire, see the USGS press release.

The Stuart Creek 2 Fire started June 19, 2013, near Eielson Air Force Base in Alaska. When the Landsat 8 image above was captured on July 13, 2013, the fire had already burned nearly 85,000 acres. So far this summer, over 70 fires have destroyed more than 1 million acres in Alaska. Still noticeable on both images is the scar left by the 2012 Dry Creek Fire (on the left) that burned over 48,000 acres.

Oil and natural gas production are the primary industries for Odessa (left) and Midland (right) in western Texas. The Landsat 5 and Landsat 8 images above show the expansion of the oil industry in this region over the past 29 years. The white dots (oil well locations) increase noticeably between these two images.

Started on June 11, 2013, the Black Forest Fire near Colorado Springs, Colorado, (lower left) was the state’s most destructive wildfire in history, burning over 14,000 acres and destroying more than 500 homes. The images above show the area as seen from the Landsat 7 satellite (acquired April 27, 2013) and Landsat 8 satellite (acquired June 22, 2013). The burned area can easily be seen in red tones.

The scar of the May 20 EF-5 tornado that leveled much of Moore, Oklahoma, is clearly visible in the false-color image above. Acquired on June 2 by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on NASA's Terra satellite, the image combines green, red, and infrared wavelengths of light to better distinguish between water, vegetation, bare ground, and human developments. Water is blue. Buildings and paved surfaces are blue-gray. Vegetation is red. The tornado track appears as a beige stripe running west to east across this image; the color reveals the lack of vegetation in the wake of the storm.

A wildfire that started on May 2 near Camarillo in southern California was captured by the Landsat Data Continuity Mission (LDCM), the newest Landsat satellite, as it passed over the Springs Fire on May 4. The false-color image from LDCM's Operational Land Imager (OLI) reveals the extent of the burned area in comparison to the March 2010 Landsat 5 image of the same area. Unburned vegetation appears dark green and burned areas are red, with the most severely burned areas the darkest. Satellite data such as the above are used to develop burn severity maps, often within hours of a wildfire, helping crews on the ground evaluate possible flood and landslide risks. To learn more about how scientists assess burn severity with satellite images, go to http://mtbs.gov/.

The Landsat Data Continuity Mission (LDCM) satellite acquired these images of the Salton Sea in Southern California on March 24, 2013. The black and white image is from LDCM’s Thermal Infrared Sensor (TIRS), which shows the amount of heat (thermal energy) radiating from the landscape. Cooler areas are dark, while warmer areas are bright. Use the slider to compare the thermal image to a natural color image acquired by the Operational Land Imager (OLI) instrument aboard the LDCM satellite.

The Landsat Data Continuity Mission (LDCM), launched on February 11, captured this image on March 18 where the Great Plains meet the Front Range of the Rocky Mountains in Wyoming and Colorado. This natural color Landsat scene emulates the true colors the human eye would see from space.

LDCM will begin its normal operations in May when NASA turns the mission over to the USGS. Images from the new satellite will start being added to the Landsat Data Archive at EROS and distributed for free over the Internet.

The Landsat Data Continuity Mission (LDCM) spacecraft, the next generation Landsat satellite, is scheduled for launch at 10:02 a.m. PST on Monday, February 11, 2013. The LDCM spacecraft will be launched atop an Atlas V rocket from Space Launch Complex 3E at Vandenberg Air Force Base near Lompoc, California. The public is invited to view the launch from Providence Landing Park in Lompoc. The February 8, 2011, Landsat 5 image above shows the area of the Vandenberg Air Force Base. Areas of interest to the LDCM launch are labeled. More information can be found on the Image Gallery or Landsat website.

Built in 1975, the Mercedes-Benz Superdome, previously known as the Louisiana Superdome, in New Orleans, Louisiana, hosted six Super Bowls between 1978 and 2002 and sheltered thousands of residents during Hurricanes Georges (1998) and Ivan (2004). However, when Hurricane Katrina came ashore on August 29, 2005, the Superdome suffered massive damage and severe flooding, as shown in the September 2005 image above, threatening the safety of residents once again seeking shelter there. A little more than a year later in September 2006, the Superdome, home to the New Orleans Saints, reopened its doors. The March 2012 image above shows the renovations to New Orleans and the Superdome.

This Sunday, February 3, the Mercedes-Benz Superdome is hosting the Baltimore Ravens and San Francisco 49ers in Super Bowl XLVI, the first Super Bowl hosted at the Superdome since the 2005 storm.
