Operational Status Landsat 8 Collecting approximately 725 new scenes per day; supports 8-day revisit cycle Improvements are bringing favorable responses from users: Crisper images; less color saturation Better resolution of snow and ice-covered regions Detection of water-column constituents Better cloud screening Landsat 7 Sufficient fuel for a few more years of operation; limited subsystem redundancy Could be a candidate for first-ever NASA satellite refueling mission Collecting about 475 new scenes per day; about 22% of pixels missing per scene (faulty scan-line corrector) L7 collection strategy modified to concentrate on continental coverage; L8 capturing continental imagery plus islands & reefs NGAC Satellite Update – Slide 2

Results of a Free and Open Landsat Data Policy From October 1, 2008 through September 30, 2014 a cumulative total of 23,264,483 Landsat Scenes were downloaded. A total of 9,420,878 scenes were downloaded in fiscal year 2014! Free and open data policy October 1, 2008 Landsat Scenes Delivered by USGS EROS Center (Cumulative)

National Plan for Civil Earth Observations July 2014: OSTP released the National Plan for Civil Earth Observations, making recommendations to support a range of Earth Observation (EO) efforts, including NASA/USGS joint efforts to sustain moderate-resolution, multispectral, satellite-based EO; see: http://www.whitehouse.gov/sites/default/files/microsites/ostp/NSTC/nati onal_plan_for_civil_earth_observations_-_july_2014.pdf http://www.whitehouse.gov/sites/default/files/microsites/ostp/NSTC/nati onal_plan_for_civil_earth_observations_-_july_2014.pdf The NASA/USGS Sustainable Land Imaging Architecture Study Team completed its work this summer and provided a report to NASA HQ The Administration is nearing a decision on the type of satellite to build for the next Landsat mission; funding plans will likely be included in the President’s fiscal year 2016 budget proposal to Congress Slide 5

2015 Guidance to LAG Landsat Advisory Group The LAG is requested to provide advice and recommendations on Landsat- related issues for consideration by the NGAC The USGS is highly pleased with the recent (draft) LAG paper, prepared in response to 2014 guidance: “Review and update the 2012 LAG paper, ‘The Value Proposition for Ten Landsat Applications’….” The USGS is considering several options for 2015 guidance and will consult with LAG members over the next few weeks
