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.

Artificial satellites and space probes in the 1970s Year Origin Name Target Status Description 1970 Japan: Ohsumi: Earth: Success: First Japanese satellite. Japan became the fourth nation after the USSR, USA and France to successfully put an artificial satellite into orbit on its own. West Germany: DIAL Earth Success Second German satellite.
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.
A satellite in a geostationary orbit appears stationary, always at the same point in the sky, to ground observers. Popularly or loosely, the term "geosynchronous" may be used to mean geostationary. [1] Specifically, geosynchronous Earth orbit (GEO) may be a synonym for geosynchronous equatorial orbit, [2] or geostationary Earth orbit. [3]
Scientists are set to create an artificial ... requiring twin spacecraft to manoeuvre with a 1 millimetre level of accuracy as they orbit Earth. ... The two Proba-3 satellites will orbit 144 ...
Geocentric orbit: An orbit around the planet Earth, such as that of the Moon or of artificial satellites. Selenocentric orbit (named after Selene): An orbit around Earth's Moon. Areocentric orbit (named after Ares): An orbit around the planet Mars, such as that of its moons or artificial satellites.
With a lopsided orbit stretching from 370 miles (600 kilometers) to 37,000 miles (60,000 kilometers) away, the satellites will take nearly 20 hours to circle the world.
