It is a joint NASA / USGS program. On 23 July 1972, the Earth Resources Technology Satellite was launched. This was eventually renamed to Landsat 1 in 1975. [ 1 ] The most recent, Landsat 9, was launched on 27 September 2021. The instruments on the Landsat satellites have acquired millions of images.

Earth Observing System. The Earth Observing System (EOS) is a program of NASA comprising a series of artificial satellite missions and scientific instruments in Earth orbit designed for long-term global observations of the land surface, biosphere, atmosphere, and oceans. Since the early 1970s, NASA has been developing its Earth Observing System ...
Landsat 7 has an average return period of 16 days. For many smaller areas, images with resolution as fine as 41 cm can be available. [7] Satellite imagery is sometimes supplemented with aerial photography, which has higher resolution, but is more expensive per square meter.
In 2016, NASA's Restore-L satellite was intended to refuel Landsat 7. [4]In 2020, SPIDER was added and the name was changed from Restore-L to OSAM-1. On 1 March 2024, NASA announced that OSAM-1 had been cancelled due to "continued technical, cost, and schedule challenges, and a broader community evolution away from refueling unprepared spacecraft."
The first satellite to use SvalSat was Landsat 7, which was launched on 15 April 1999. It was followed up by three other EOS satellites: Terra, Aqua and QuikSCAT. [11] To ensure a sustainable financing of operations, NSC started negotiating with other potential customers. However, the project was rejected by the Indian Space Research Organisation.
An Earth observation satellite or Earth remote sensing satellite is a satellite used or designed for Earth observation (EO) from orbit, including spy satellites and similar ones intended for non-military uses such as environmental monitoring, meteorology, cartography and others. The most common type are Earth imaging satellites, that take ...
The mission supports services and applications such as agricultural monitoring, emergencies management, land cover classification, and water quality. Sentinel-2 has been developed and is being operated by the European Space Agency. The satellites were manufactured by a consortium led by Airbus Defence and Space in Friedrichshafen, Germany.
