May 14, 2012 - Landsat 7 Maneuver to Return to WRS

Landsat 7 maneuvered away from a piece of space debris in mid-April, which meant that some data are outside of the Worldwide Reference System. On Tuesday, May 15, the USGS Flight Operations Team will execute a maneuver that over several weeks will gradually bring Landsat 7 back into the correct orbit. There will be no new acquisitions from Tuesday May 15, through mid-day Wednesday May 16, 2012.

May 8, 2012 - Landsat 5 Thematic Mapper Ceases Routine Acquisitions - Update

After a silent winter, the USGS turned on the Landsat 5 Thematic Mapper (TM) in late April to determine the state of the electronics problem that suspended operations in November, 2011. Unfortunately, several alternate methods of acquisitions did not alleviate the problem, which severely limits any further acquisitions with the TM. (Read More)

April 25, 2012 - Testing the Landsat 5 Thematic Mapper

Plans to test the Landsat 5 Thematic Mapper downlink begin today, April 25, 2012. Data may be visible on the EarthNow!  during testing. However, the data will not be available for download by users until completion of analysis and calibration.

April 18, 2012 - Landsat 7 Maneuvers to Avoid Space Debris

More than half a million pieces of space junk are in orbit floating in and around operational missions. In coordination with NASA, the USGS keeps constant vigil to avoid space debris that might collide with the Landsat 5 and 7 satellites. (Read More)

April 12, 2012 - Landsat 5 Captures MSS Data

Landsat 5 recently captured and downlinked Multispectral Scanner (MSS) images for the first time in over a decade. An MSS sensor first flew on Landsat 1 in 1972 and was aboard each of the Landsats 1-5. The MSS was powered down on Landsat 5 in the late 1990's, but the USGS recently turned on the MSS to determine the current state of the sensor. (Read More)

April 10, 2012 - USGS Seeks Landsat Science Team Proposals

The U.S. Geological Survey, Center for EROS, Sioux Falls, South Dakota, is seeking proposals from scientists and engineers interested in serving on the Landsat Science Team. The Landsat Science Team will conduct research on issues critical to the effective utilization of Landsat data. (Read More)

March 5, 2012 - Anne Castle, DOI Assistant Secretary for Water and Science, recently discussed Landsat's 40 years.

At the Association for American Geographer's Annual Meeting, Anne Castle spoke to Landsat's long legacy, its benefit to humanity, and the future of the mission. In her presentation, you can find striking images of our planet, graphics on how Landsat is for research and operational analysis, statistics on the importance of free data, and the promise of the Landsat Data Continuity Mission (LDCM).

February 29, 2012 - Landsat Ground Station Operators Working Group (LGSOWG#40)

The 40th Landsat Ground Station Operators Working Group Meeting was held January 30 through February 3, 2012, in Bali, Indonesia. LGSOWG#40 was hosted by the National Institute of Aeronautics and Space (LAPAN). (Read More)

February 16, 2012 - USGS extends suspension of operations for Landsat 5

Landsat 5 imaging was suspended in November 2011 when a vital transmission component showed signs of imminent failure. The Flight Operations Team continues to explore options, which include alternate operating procedures for the Thematic Mapper and evaluation of the other sensor onboard, the Multispectral Scanner. More details can be found on this NASA webpage.

February 10, 2012 - The Thermal Infrared Sensor (TIRS) instrument

The Thermal Infrared Sensor (TIRS) instrument was shipped from NASA Goddard Space Flight Center to Orbital Sciences Corporation (OSC) in Gilbert, Arizona, where it will be integrated with the LDCM satellite bus built by OSC. The Operational Land Imager (OLI) instrument, built by Ball Aerospace Technology Corporation (BATC) in Boulder, Colorado, is currently in the process of being integrated with the spacecraft. The delivery of TIRS achieves a major milestone towards completing assembling the LDCM observatory.

February 8, 2012 - Dr. Alan Belward discusses the value of Landsat.

Alan Belward, head of the Land Resource Management Unit with the Institute for Environment and Sustainability at the European Commission's Joint Research Center, talks about why Landsat is important to global forest mapping. Dr. Belward states that Landsat is a unique tool because of its 40-year time span, its archive of global images, and its free and open access. To hear the complete interview, visit EarthSky.

February 7, 2012 - The NASA TIRS instrument

The NASA TIRS instrument development team successfully completed the Pre-Ship Review (PSR), capping a major milestone for the Landsat Data Continuity Mission. TIRS development was completed in 43 months on an aggressive schedule to meet a January 2013 launch readiness date.

About

Landsat represents the world's longest continuously acquired collection of space-based moderate-resolution land remote sensing data. Four decades of imagery provides a unique resource for those who work in agriculture, geology, forestry, regional planning, education, mapping, and global change research. Landsat images are also invaluable for emergency response and disaster relief.
