Landsat 5 Sets Guinness World Record For 'Longest Operating Earth Observation Satellite'

Landsat 5 successfully set the new Guinness World Records title for 'Longest-operating Earth observation satellite as stated in an e-mail from Guinness World Records sent to NASA Goddard Space Flight Centre in Greenbelt, Md. Outliving its three-year design life, Landsat 5 delivered high-quality, global data of Earth's land surface for 28 years and 10 months.

Aging Landsat 5 Changes Glasses

Landsat 5 has orbited Earth over 150,000 times since it was launched in 1984, making it the longest-operating Earth observing satellite of its kind. During this time, two data collection instruments onboard Landsat 5 - the thematic mapper (TM) and the multi-spectral scanner (MSS) - have transmitted over five million images of land conditions to U.S. and international ground stations.
In November 2011 an electronic malfunction in the TM transmitter forced a suspension of routine imaging. Now, after months of trying without success to restore daily TM image transmissions, USGS flight engineers will attempt only a few additional image acquisitions over specific sensor-calibration sites as the TM transmitter nears complete failure.
On a positive note, the MSS instrument onboard Landsat 5 was recently powered back on in a test mode after more than a decade of silence.

USGS extends suspension of operations for Landsat 5

Landsat 5 Earth imaging operations have been suspended for an additional 90 days while the U.S. Geological Survey Flight Operations Team (FOT) continues to investigate options for the resumption of imaging.
Landsat 5 imaging was halted in November 2011 when an electronic component vital to transmission of the satellite's Thematic Mapper (TM) data began showing signs of imminent failure. Following an unsuccessful attempt to recover the backup electronic component, the FOT is exploring potential changes to operational procedures for the primary component.

EROS satellite could be on last leg

One of the two main satellites transmitting images to the U.S. Geological Survey's EROS Data Centre near Sioux Falls could be on its last legs.
Survey officials said Friday that the 27-year-old Landsat 5 Earth observation satellite is no longer sending images due to a rapidly degrading electronic component.

Landsat 5 Mission in Jeopardy

The U.S. Geological Survey (USGS) has stopped acquiring images from the 27-year-old Landsat 5 Earth observation satellite due to a rapidly degrading electronic component.
Landsat 5 was launched in 1984 and designed to last 3 years. The USGS assumed operation of Landsat 5 in 2001 and managed to bring the aging satellite back from the brink of total failure on several occasions following the malfunction of key subsystems. There is now an increasing likelihood that the Landsat 5 mission is nearing its end.

Free U.S. Earth Imagery Sharpens Shared View of Global Challenges
Free, easily accessible U.S. satellite data enables any citizen, scientist, or analyst who can use the information to contribute to a shared vision of the challenges facing our planet.
That's the message the newly-appointed director of the U.S. Geological Survey, Dr. Marcia McNutt, plans to deliver when representatives of 80 governments and over 50 participating organisations convene at the international Group on Earth Observations (GEO-VI) meeting, November 16-17, in Washington, D.C.

"Our policy of providing free Landsat data supports a central GEO goal: to promote global distribution of earth observation data. With a continuous record of earth observation since 1972, Landsat provides the most complete set of land surface information as well as a vital historical perspective for researchers, decision makers, and commercial users around the world" - Dr. Marcia McNutt

Landsat 5 Fully Operational After Brief Interruption
Landsat 5, the quarter-century-old satellite workhorse, is back in its traces.
When the historically reliable earth observation satellite began tumbling in space on the morning of August 13, engineers from the USGS Landsat Flight Operations Team immediately started processes to protect the satellite and to restore capability.
The spacecraft was stabilised quickly and recovery operations initiated. During the following two days, the sensor was not used and no data were collected.  By August 17, the systems were back in order and full capability was restored.
