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 ...
For Earth this means a period of just under 12 hours at an altitude of approximately 20,200 km (12,544.2 miles) if the orbit is circular. [16] Molniya orbit: A semi-synchronous variation of a Tundra orbit. For Earth this means an orbital period of just under 12 hours. Such a satellite spends most of its time over two designated areas of the ...
High Earth orbit. Space of high Earth orbits (HEO), between medium Earth orbits (MEO) and the orbit of the Moon. A high Earth orbit is an geocentric orbit with an apogee farther than that of the geosynchronous orbit, which is 35,786 km (22,236 mi) away from Earth. [1] In this article, the non-standard abbreviation of HEO is used for high Earth ...
Chandra is an Earth satellite in a 64-hour orbit, and its mission is ongoing as of 2024. Chandra is one of the Great Observatories , along with the Hubble Space Telescope , Compton Gamma Ray Observatory (1991–2000), and the Spitzer Space Telescope (2003–2020).

TrackSat - Satellite tracker – can track satellites orbiting the Earth in real time and predict their passes over your specific geolocation. Includes satellites such as ...
Communication system. [edit] The radio communication system of Voyager 1 was designed to be used up to and beyond the limits of the Solar System. It has a 3.7-metre (12 ft) diameter high-gain Cassegrain antenna to send and receive radio waves via the three Deep Space Network stations on the Earth. [ 21 ]
Webb operates in a halo orbit, circling around a point in space known as the Sun–Earth L 2 Lagrange point, approximately 1,500,000 km (930,000 mi) beyond Earth's orbit around the Sun. Its actual position varies between about 250,000 and 832,000 km (155,000–517,000 mi) from L 2 as it orbits, keeping it out of both Earth and Moon's shadow.
Deep Space Climate Observatory (DSCOVR; formerly known as Triana, unofficially known as GoreSat[ 3 ]) is a National Oceanic and Atmospheric Administration (NOAA) space weather, space climate, and Earth observation satellite. It was launched by SpaceX on a Falcon 9 v1.1 launch vehicle on 11 February 2015, from Cape Canaveral. [ 4 ]
