Landsat 5 launching on March 1, 1984 from Vandenberg AFB
Mar 1, 2009Earth Observing Landsat 5 Turns 25

Mar 1, 2009 • 132,969 … 132,970 … 132,971. Like a trusty watch counting up the minutes, the Landsat 5 satellite keeps on ticking, orbit after orbit around the Earth. Well beyond its design lifetime of 15,000 orbits, the satellite’s trajectory could go askew or its instruments could malfunction at any moment. But not today. […]

Mar 1, 2007Landsat 5 Turns 23!

On this day in 1984, Landsat 5 was launched into orbit. Today, after 23 years of service, Landsat 5 is still operational. The original design life of Landsat 5 was just three years, but it has become the longest continuously operating Earth observation system in the U.S. civilian satellite fleet. Landsat 5’s tremendous life span is a […]

Jan 8, 2007Landsat 5 at 120K+ Orbits

On September 23, 2006 Landsat 5 made its 120,000th orbit around Earth (equating to nearly 3.1 billion miles traveled). Tampa, Florida was one of the locations found on the path of the 120,000th orbit (see image to right). Landsat 5 was launched in 1984 with a five year design life. Thanks to good engineering and a knowledgeable […]

Nov 3, 2006Watch as Landsat Data Are Collected

The U.S. Geological Survey (USGS) has made it possible for you to watch as swaths of data from the Landsat 5 and Landsat 7 satellites are collected and downloaded to the USGS Center for Earth Resources Observation and Science (EROS) in Sioux Falls, SD. USGS EarthNow! displays data received from the Landsat 5 and Landsat 7 satellites […]

Sep 28, 2006Landsat Legacy Oral Histories Recorded in Santa Barbara

A set of Landsat Legacy interviews were conducted just north of Santa Barbara, CA on Thursday, Sept. 28, 2006. Landsat veterans from the Raytheon Santa Barbara Research Center were digitally recorded as they recounted their experiences building the MSS, TM, ETM, and ETM+ sensors that flew on the Landsat satellites. In the morning, Dr. Robert Tally, an […]

Aug 18, 2006All Landsat 5 IGSs Online, Except One

Landsat 5, operating with its solar array in fixed position, is now downlinking data to all of its international ground stations (IGS) with the exception of Kiruna, Sweden. + Landsat 5 operating with solar array in fixed position

Aug 17, 2006Landsat 5 Operating With Solar Array in Fixed Position

After successfully battling Solar Array Drive problems over the past eight months, the Landsat 5 Flight Operations Team has transitioned the Landsat 5 satellite into operation with the solar array in a fixed position. This transition was carried out yesterday with minimum impact to the mission. As reported by USGS, “When Landsat 5 experienced problems […]

Jun 13, 2006Landsat Semi-Annual Calibration Meeting Held

Jun 13, 2006 • NASA and USGS work jointly to insure the radiometric and geometric calibrations, both current and historical, of the Landsat 5 TM and Landsat 7 ETM+ are maintained and refined. As part of this effort, NASA funds several external teams that provide independent analyses and perform vicarious radiometric calibrations. Twice yearly, these […]

Jun 12, 2006Landsat Technical Working Group Meeting Held

Jun 12, 2006 • This year’s Landsat Technical Working Group (LTWG-15) meeting was held in Sweden May 15-19, 2006. The meeting was organized by USGS and hosted by the European Space Agency at the ESRANGE facility in Kiruna, Sweden. Participants from 12 countries including members of the Landsat project and NASA staff discussed topics that focused on […]

Mar 16, 2006Landsat 5 TWTA Transmitter Problem Interrupts Data Acquisitions

After an outgassing event, the Landsat 5 X-band transmitter prematurely shut off during a data downlink to the USGS Landsat Ground Station in Sioux Falls, SD. Specifically the backup Traveling Wave Tube Amplifier (TWTA), which is a downlink power amplifier for spacecraft telecommunications, tripped an Over Current Protection circuit. In 1987, a similar anomaly forced engineers […]
