Landsat 7 Schematic. Landsat 7 was designed to last for five years, and has the capacity to collect and transmit up to 532 images per day. It is in a polar, Sun-synchronous orbit, meaning it scans across the entire Earth's surface. With an altitude of 705 km, it takes 232 orbits, or 16 days, to do so.
Landsat 7: 15 April 1999: Active: 25 years, 9 months and 21 days Operating with scan line corrector disabled since May 2003. [13] The main component on Landsat 7 was the Enhanced Thematic Mapper Plus (ETM+). Still consisting of the 15m-resolution panchromatic band, but also includes a full aperture calibration.
Landsat-8: Active NASA and USGS 2013 Follow on to Landsat-7 with improved imager OLI and thermal sensor TIRS. Landsat-9: Active NASA and USGS 2021 Follow on to Landsat-8 with OLI sensor and thermal sensor TIRS-2. Landsat-9 will extend the Landsat program to maintain the time series of these type of data.

Landsat 5-8 Operational Land Imager (OLI) [5] Developed by Ball Aerospace & Technologies Corporation, the OLI is a crucial aspect of modern LandSat vehicles. Using 7000 sensors per band (Spectrum band), the OLI on NASA's most recent LandSat (LANDSAT 8) Satellite, will image/view the entire earth every 16 days. Enhanced Thematic Mapper + (ETM+ ...

The elevation datasets are affected by mountain and desert no-data areas. These amount to no more than 0.2% of the total area surveyed, [ 11 ] but can be a problem in areas of very high relief. They affect all summits over 8,000 meters, most summits over 7,000 meters, many Alpine and similar summits and ridges, and many gorges and canyons.
The first images from space were taken on the sub-orbital V-2 rocket flight launched by the US on October 24, 1946. Satellite image of Fortaleza.. Satellite images (also Earth observation imagery, spaceborne photography, or simply satellite photo) are images of Earth collected by imaging satellites operated by governments and businesses around the world.
Copernicus is the Earth observation component of the European Union Space Programme, managed by the European Commission and implemented in partnership with the EU member states, the European Space Agency (ESA), the European Organisation for the Exploitation of Meteorological Satellites (EUMETSAT), the European Centre for Medium-Range Weather Forecasts (ECMWF), the Joint Research Centre (JRC ...
