NASA Earth science satellite fleet as of September 2020, planned through 2023. 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 ...
Derelict satellites orbiting Earth (129 P) F. Satellites formerly orbiting Earth (2 C, 54 P) G. Satellites in geostationary orbit (3 C, 13 P)
This is a list of satellites in geosynchronous orbit (GSO). These satellites are commonly used for communication purposes, such as radio and television networks, back-haul, and direct broadcast. Traditional global navigation systems do not use geosynchronous satellites, but some SBAS navigation satellites do.

Turkey: BİLSAT: Earth: Success: BİLSAT, Turkey's first earth observation satellite: 2002 US: CONTOUR: Comet Encke: Failure: CONTOUR launched, but lost during early trajectory insertion. Europe ...
Of the Solar System's eight planets and its nine most likely dwarf planets, six planets and seven dwarf planets are known to be orbited by at least 300 natural satellites, or moons. At least 19 of them are large enough to be gravitationally rounded; of these, all are covered by a crust of ice except for Earth's Moon and Jupiter's Io. [1]
Elon Musk now controls nearly two thirds of all active satellites orbiting Earth following the launch of the 7,000th Starlink satellite this week. The internet satellite constellation, ...
For Earth orbiting satellites below the height of about 800 km, the atmospheric drag is the major orbit perturbing force out of all non-gravitational forces. [11] Above 800 km, solar radiation pressure causes the largest orbital perturbations. [12]
This list of space telescopes (astronomical space observatories) is grouped by major frequency ranges: gamma ray, x-ray, ultraviolet, visible, infrared, microwave, and radio. Telescopes that work in multiple frequency bands are included in all of the appropriate sections.
