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.

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]
A day after launch an amateur astronomer in the Netherlands was one of the first to publish a video showing the satellites flying across the sky as a "train" of bright lights. [30] By five weeks post launch, 57 of the 60 satellites had been "healthy" while 3 were non-operational and derelict, but deorbited due to atmospheric drag. [31]
A trail of Starlink satellites appears in the night sky five days after its launch. ... The number of satellites in Earth's orbit has skyrocketed from about 1,000 in 2010 to more than 10,000 today.
