In May of 1972, two months before the launch of Landsat 1, engineers from Hughes Aircraft Company took their engineering model of the Multispectal Scanning System (MSS) out to Yosemite National Park, set it up on Glacier Point, and took this test image of Half Dome from a 2.5 miles away. The image composite shown above uses the MSS bands 3, 2, and 1.
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.
Building a satellite is a major collaboration and involves the hard work of many different types of engineers. The engineering process for Landsat involves defining

Back in 2002, NASA created a film using satellite data that took viewers on a tour of Earth’s frozen regions. This year, NASA visualizers are
