The first images from space were taken on the sub-orbital V-2 rocket flight launched by the U.S. 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.
A weather satellite or meteorological satellite is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator ). [1]
Earth observation satellite missions developed by the ESA as of 2019. Earth observation satellites are Earth-orbiting spacecraft with sensors used to collect imagery and measurements of the surface of the earth. These satellites are used to monitor short-term weather, long-term climate change, natural disasters.
The Visible Infrared Imaging Radiometer Suite ( VIIRS) is a sensor designed and manufactured by the Raytheon Company on board the polar-orbiting Suomi National Polar-orbiting Partnership (Suomi NPP), NOAA-20, and NOAA-21 weather satellites. [1] VIIRS is one of five key instruments onboard Suomi NPP, launched on October 28, 2011. [2]
In current usage, the term remote sensing generally refers to the use of satellite - or aircraft-based sensor technologies to detect and classify objects on Earth. It includes the surface and the atmosphere and oceans, based on propagated signals (e.g. electromagnetic radiation ).
The satellite was built by Lockheed Martin, based on the A2100A platform, and expected to have a useful life of 15 years (10 years operational after five years of standby as an on-orbit replacement). GOES-17 is intended to deliver high-resolution visible and infrared imagery and lightning observations of more than half the globe.
Athens as seen by the SPOT 5 satellite in 2002. SPOT ( French: Satellite Pour l’Observation de la Terre, [1] lit. "Satellite for observation of Earth") is a commercial high-resolution optical Earth imaging satellite system operating from space. It is run by Spot Image, based in Toulouse, France. It was initiated by the CNES ( Centre national ...
It notes that viewing times are not 100% accurate and can vary by 10 minutes, as the satellite orbits may change. The site says the satellites are only visible for about four minutes. In the ...
