November 23, 2011 - Dr. John Schott and his 30 years with Landsat

Since 1981, Dr. John Schott has been involved in calibration of the Landsat instruments from his home institution, Rochester Institute of Technology. He is also involved in emerging science that leverages the 40-year Landsat archive as well as working with simulated images from the next sensor, the Operational Land Imager, that will fly on the Landsat Data Continuity Mission.

November 18, 2011 - Landsat 5 Mission in Jeopardy

Over the past 10 days, problems with the amplifier have led to drastically reduced image download capabilities, a sign of impending failure. USGS engineers have suspended imaging activities for an initial period of 90 days in order to explore every possible option for restoring satellite-to-ground image transmissions. This USGS News Release provides more details.

November 18, 2011 - 27 Years of Earth Images for the World

It may not be widely known that Landsat 5 is the longest operating Earth-orbiting satellite. Launched in 1984, Landsat 5 has downlinked over five million images to the USGS and international ground stations throughout the world. The archive of observations derived from the Landsat 5 provides our international community with a strong foundation of unbiased information on global land-surface features. (Read More)

November 17, 2011 - Possible interruptions in Landsat 5 acquisitions.

Landsat 5 has been on orbit for more than 27 years. Over time, the USGS's Flight Operations Team has addressed numerous challenges as the spacecraft has aged.

Due to ongoing issues with the Landsat 5 transmitter, imaging may be interrupted in order to evaluate options for continued operations. Future information will be posted here. Please consider subscribing to the Mission Headlines RSS feed or following Landsat on Twitter.

August 16-18, 2011 - Landsat Science Team Meeting

The Landsat Science Team Meeting was held at USGS EROS Center in Sioux Falls, South Dakota. Current and future mission status reports were presented, and members provided the results of their five years of Landsat Science Team research.

June 28, 2011 - Landsat 7 was overhead

Landsat 7 was overhead on Saturday, June 25, 2011 as the Souris River in Minot, North Dakota exceeded the 1881 flooding record by over 4 feet. The images below show the area before the flooding on May 16, and again on June 25. (See Imagery)

June 7, 2011 - USGS hosted the 20th Landsat Technical Working Group meeting.

Participants from 17 countries, including members of the USGS and NASA Landsat and Landsat Data Continuity Mission (LDCM) Projects, represented 23 U.S. and international ground stations and discussed a wide range of technical topics. Special guest, Anne Castle, U.S. Department of the Interior (DOI) Assistant Secretary for Water and Science, welcomed the attendees and provided perspective on the key role they play in current and future international land imaging cooperation.

March 24, 2011 - MSS orders held until April 1st

Starting on Friday, March 25th, MSS orders will be held so that radiometric enhancements can be implemented. MSS processing will recommence on April 1st, and notices will be sent, as typical, when scenes are completed. For more information on these enhancements, please see the L1-5 MSS Calibration page.

March 22, 2011 - Landsat Science Team Members Interview with EarthSky

Landsat Science Team members have participated in a series of interviews with EarthSky. Dr. Bob Bindschadler discusses the Landsat Image Mosaic of Antarctica, and Dr. Curtis Woodcock talks about monitoring Earth's forests.

March 16, 2011 - Landsat 5 Update

As of March 16, 2011, Landsat 5 is acquiring data normally.

March 15, 2011 - Short-term Suspension of Landsat 5 Acquisitions

On March 14, 2011, Landsat 5 experienced a minor anomaly. The spacecraft is currently operating normally, but it will take a few days to return the instrument to a nominal temperature. Data is expected to be available at the end of the week.

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.
