Eight months ago, on June 5, 2013, the U.S. Geological Survey decommissioned the venerable Landsat 5 satellite. That day, the USGS Landsat Flight Operations Team transmitted the last command to Landsat 5, effectively terminating the mission and leaving it in a disposal orbit.
On November 22, 2013, Landsat 8 overflew the defunct Landsat 5 over northwestern Brazil (Path 233 Row 60). Thanks to some clever work by Mike Gartley, a Research Scientist with the Digital Imaging and Remote Sensing group at Rochester Institute of Technology (RIT)—a group that has long participated in Landsat calibration and validation—Landsat 5 was spotted in that Landsat 8 image.
In the image, the Landsat 5 satellite is seen as a streak of pixels (dark or light depending on the spectral band). There is one image from each of Landsat 8’s OLI bands—except for Band 7, or SWIR-2, where she blended into the clouds and was impossible to distinguish. In these images Landsat 5 is much closer to Landsat 8 than she is to the Earth.
