OSAM-1 Lead Systems Engineer Wendy Morgenstern discusses NASA’s On-orbit Servicing, Assembly, and Manufacturing 1 mission to robotically refuel Landsat 7, a satellite that wasn’t designed to be serviced.

Every full moon, Landsat 8 turns its back on Earth. As the satellite’s orbit takes it to the nighttime side of the planet, Landsat 8 pivots to point at the moon. It scans the distant lunar surface multiple times, then flips back around to continue its task of collecting land-cover information of the sunny side of Earth below. These monthly lunar scans are key to ensuring the land-imaging instrument aboard Landsat 8 is detecting light consistently. For a well-known and stable source of light, nothing on our planet beats the moon, which lacks an atmosphere and has an unchanging surface, barring the odd meteorite.
To continually map the Earth’s surface using Landsat data, an entirely new projection had to be created. This new projection was created by John Parr Snyder and is known as the Space Oblique Mercator (SOM) projection. It is considered, “one of the most complex projections ever devised” according to cartographic historian, John W. Hessler.
