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.
List of USA satellites. This is a list of satellites and spacecraft which have been given USA designations by the United States Air Force. These designations have been applied to most United States military satellites since 1984, and replaced the earlier OPS designation. As of June 2022, USA designations have been assigned to 331 space satellites.

The satellites are pinpoint, while stars have created star trails due to Earth's rotation. A geostationary orbit, also referred to as a geosynchronous equatorial orbit [a] ( GEO ), is a circular geosynchronous orbit 35,786 km (22,236 mi) in altitude above Earth's equator, 42,164 km (26,199 mi) in radius from Earth's center, and following the ...
US-A satellites were a major source of space debris in low Earth orbit. The debris is created two ways: During 16 reactor core ejections, approximately 128 kg of NaK-78 (a fusible alloy eutectic of 22% and 78% w/w sodium and potassium, respectively) escaped from the primary coolant systems of the BES-5 reactors. The smaller droplets have ...

In 2008, more than 150 Earth observation satellites were in orbit, recording data with both passive and active sensors and acquiring more than 10 terabits of data daily. [1] By 2021, that total had grown to over 950, with the largest number of satellites operated by US-based company Planet Labs. [4]
