A comprehensive list of Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the Earth. The list covers both public domain and private domain satellites, with name, status, agency, launch date, and description.
Satellite imagery are images of Earth collected by imaging satellites operated by governments and businesses around the world. Learn about the history, types, and uses of satellite imagery in various fields such as weather, oceanography, agriculture, and biodiversity.
Google Earth is a web and computer program that renders a 3D globe with satellite images, aerial photography, and GIS data. Users can explore the Earth, add their own data, view photos, Street View, and more, but also face privacy and security issues.
Terra is a NASA satellite that orbits Earth in a Sun-synchronous orbit at an altitude of 705 km. It carries five remote sensors to monitor the atmosphere, land, and water, and has taken many images of Earth's features.
The Landsat program is the longest-running enterprise for acquisition of satellite imagery of Earth, launched by NASA and USGS since 1972. Learn about the history, satellite chronology, spatial and spectral resolution, and uses of Landsat imagery for various fields of research and applications.
NASA Earth Observatory is an online publishing outlet for NASA that provides satellite imagery and scientific information on climate and environment. It is funded by public money and part of the EOS Project Science Office at Goddard Space Flight Center.
Landsat 7 was launched on 15 April 1999 and is a satellite imagery program managed by NASA and USGS. It has a Sun-synchronous orbit, a 15-metre panchromatic band, and a 30-metre multispectral band, and provides data for various scientific applications.
It was the first satellite to capture colour images from space and acted significantly as a medium of communications. [ 1 ] After the success of TIROS-1 and ATS-3, NASA in conjunction with United States Geological Survey (USGS), progressed forward in Earth observation through a series of Landsat satellites launched throughout the 1970s and 1980s.
