Landsat and LDCM Headlines 2011
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. For more details, please see the USGS Newsroom
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.
If you are curious about the Earth and how it has changed, Landsat 5 is for you. Questions that have been asked of the archive relate to: forests, farming, city expansion, natural disasters, coral reefs, glaciers, international borders, national parks, geology, biology, and the list goes on and on. And all these questions can be answered with an eye on change over the last 27 years – what did Atlanta, Georgia look like in 1984 compared to today? How much more land is used in Africa today for growing food than 20 years ago? Are the glaciers really receding? How has the region around Chernobyl changed? And so forth.
As Landsat 5 has aged, while continuously imaging the Earth day after day for 27 years, it has exhibited numerous problems, some predicted and others unforeseen. Landsat 5 has survived many setbacks, forcing flight engineers to switch on back-up components or find workarounds. Lots of fuel, the design and workmanship of the satellite, innovative workarounds and problem-solving, and finally, a bit of luck have all helped Landsat 5 keep working, monitoring the Earth, and providing an unparalleled archive of images for all humankind.
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.

This year's Landsat Technical Working Group (LTWG#20) meeting was held in Sioux Falls, SD, USA, May 23-27, 2011. 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.
Landsat Project presentations included Landsat 5 and Landsat 7 mission statuses, Global Land Survey status, the Landsat Global Archive Consolidation initiative, operational Data Validation & Exchange (DV&E) status, and Calibration/Validation. The Landsat Project also hosted a technical workshop on Landsat 1-5 Multi-Spectral Scanner (MSS) Data Processing current progress and future plans. LDCM presentations included Project and Ground System status including plans and timelines for LDCM Ground System processing software availability, the LDCM Space-to-International Cooperator (IC) interface, and DV&E and Ground Station Certification. A Landsat Science Team update was also presented, providing information on several key application and research projects. NASA also provided attendees with an overview of the overall LDCM mission status. Concurrent with the typical LTWG agenda, the USGS also hosted a 3-day Ground System Technical Workshop for its International Cooperator attendees. The workshop covered both Landsat and LDCM (Landsat 8) ground system technical information such as requirements, interfaces, design, and implementation details.
Each International Cooperator briefed the group on the status of their ground systems including electronic data delivery capabilities and challenges, presented their future satellite mission(s), provided an overview of their data distribution model(s), and discussed current status of their Landsat Global Archive Consolidation activities.
International Cooperators and U.S. attendees included representatives from the following countries and organizations:

The William T. Pecora Award is presented annually to individuals or groups that have made outstanding contributions toward understanding the Earth by means of remote sensing. The Department of the Interior (DOI) and the National Aeronautics and Space Administration (NASA) jointly sponsor the award. The award was established in 1974 to honor the memory of Dr. William T. Pecora, former Director of the U.S. Geological Survey and Under Secretary, Department of the Interior. Dr. Pecora was a motivating force behind the establishment of a program for civil remote sensing of the Earth from space. His early vision and support helped establish what we know today as the Landsat satellite program.
The Award Committee must receive nominations for the 2011 award by June 1, 2011. Instructions for preparing a nomination and other information about the award can be found on the Pecora Award web site:
April 8, 2011 – The First Landsat Scientist
On March 17, 2011, the Landsat program lost one of its first champions, Stanley C. Freden. Dr. Freden was a physicist who was the first project scientist for ERTS-1 (now Landsat 1) and continued in that role through Landsat 3.
His full obituary can be found at http://www.washingtonpost.com/local/obituaries/stanley-c-freden-nasa-scientist-and-early-contributor-to-landsat-dies-at-83/2011/04/05/AFrMsFrC_story.html

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.
March 13, 2011 – Pending MSS and L4 TM Calibration Release
In the upcoming weeks, the Landsat Project will incorporate new radiometric enhancements for all Multi-Spectral Scanner (MSS) and Landsat 4 Thematic Mapper (TM) thermal data. A notice will be posted when the new calibrations are released in early April. At that time, all processed MSS and Landsat 4 TM data will be purged from the servers in order to ensure that all future MSS and L4 TM data have the new calibrations applied.
