Landsat 5 orbited the planet more than 150,000 times over the course of 28 years while transmitting over 2.5 million images of land surface conditions around the world.

Developed by NASA, Landsat 5 was launched from Vandenberg Air Force Base in California on March 1, 1984, and like Landsat 4, carried the Multispectral Scanner (MSS) and the Thematic Mapper (TM) instruments. Landsat 5 delivered Earth imaging data for nearly 29 years— setting a Guinness World Record for 'Longest Operating Earth Observation Satellite,' before being decommissioned on June 5, 2013. Clearly, this satellite outlived its three-year design.

Landsat 5 Satellite Orbit Facts

Orbited the Earth at 705 km (438 mi) in a sun-synchronous, near-polar orbit (98.2 degrees inclination)
Circled the Earth every 99 minutes, fourteen orbits a day

Had a 16-day repeat cycle with an equatorial crossing time of 9:45 a.m. (+/- 15 minutes)
Acquired on the Worldwide Reference System-2 (WRS-2) path/row system, with swath overlap (or sidelap) varying from 7 percent at the Equator to a maximum of approximately 85 percent at extreme latitudes.

Landsat 5 First Light Image over South Texas Gulf Coast — One of the first Landsat 5 images in the archive shows Corpus Christi and Padre Island National Seashore. The image was acquired on March 6, 1984 and is shown as a false color composite using the near infrared, red, and green bands (bands 4,3,2).

Landsat 5 Instruments

Landsat 5 carried the Multispectral Scanner (MSS) and the Thematic Mapper (TM) sensors. MSS data acquisitions over the United States ceased in 1992 and global acquisitions ended in 1999. After the TM sensor failed in November 2011, the MSS instrument was brought back online. From June 2012 until January 2013, over 15,000 MSS scenes were collected.

Landsat 5 First Light Image of Lake Superior — One of the first clear Landsat 5 images shows an icy Lake Superior, northern Minnesota, and the Wisconsin's Apostle Islands. The Thematic Mapper (TM) image is shown as a false color composite using the near infrared, red and green bands (bands 4,3,2) and was acquired on March 6, 1984, just 5 days after the launch.

Multispectral Scanner (MSS)

Four spectral bands (identical to Landsat 1 and 2):
- Band 4 Visible Green (0.5 to 0.6 µm) — powered off due to high current in August 1995
- Band 5 Visible Red (0.6 to 0.7 µm)
- Band 6 Near-Infrared (0.7 to 0.8 µm)
- Band 7 Near-Infrared (0.8 to 1.1 µm)
Six detectors for each spectral band provided six scan lines on each active scan
Ground Sampling Interval (pixel size): 57 x 79 m

Thematic Mapper (TM)

Added the mid-range infrared to the data
Seven spectral bands, including a thermal band:
- Band 1 Visible Blue (0.45 - 0.52 µm) 30 m
- Band 2 Visible Green (0.52 - 0.60 µm) 30 m
- Band 3 Visible Red (0.63 - 0.69 µm) 30 m
- Band 4 Near-Infrared (0.76 - 0.90 µm) 30 m
- Band 5 Near-Infrared (1.55 - 1.75 µm) 30 m
- Band 6 Thermal (10.40 - 12.50 µm) 120 m
- Band 7 Mid-Infrared (2.08 - 2.35 µm) 30 m
Ground Sampling Interval (pixel size): 30 m reflective, 120 m thermal
