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, 55 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.
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]
Infrared light is of lower energy than visible light, hence is emitted by sources that are either cooler, or moving away from the observer (in present context: Earth) at high speed. As such, the following can be viewed in the infrared: cool stars (including brown dwarves ), nebulae , and redshifted galaxies .
