23-07-2012 08:59 The Landsat program is the longest continuous global record of Earth observations from space -- ever. On July 23, 1972 NASA launched the first satellite in this program, then known as ERTS, the Earth Resources Technology Satellite and later renamed Landsat 1. In honor of today (Monday, July 23, 2012) being the 40th birthday of Landsat, NASA edited together selections of an archive video from 1973 about the ERTS launch. Featured in this 1973 video was a senior geologist at NASA, Nicholas Short, and at Dartmouth College, Robert Simpson and David Lindgren. NASA and the US Department of the Interior through the US Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in 2013.
