These satellites are used to monitor short-term weather, long-term climate change, natural disasters. Earth observations satellites provide information for research subjects that benefit from looking at Earth’s surface from above (such as meteorology , oceanography , terrestrial ecology , glaciology , atmospheric science , hydrology , geology ...

For moons, see Natural satellite. For other uses, see Satellite (disambiguation). Two CubeSats orbiting around Earth after being deployed from the ISS KibÅ module's Small Satellite Orbital Deployer A ...
ULTRASAT will observe a large patch of sky with a 210 square degrees field of view, alternating every six months between the southern and northern hemisphere. The satellite is planned to be launched into a geosynchronous orbit in early 2026. [1] [2] All ULTRASAT data will be transmitted to the ground in real time. Upon detection of a transient ...
Researchers have long warned about the impact of satellites in our view from the ground – but it is affecting the view in space, too
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.
Elon Musk's space exploration company, SpaceX, plans to launch up to 42,000 satellites into orbit to beam internet down to remote parts of the Earth. SpaceX has already put close to 200 Starlink ...
Fifth GPS Block III satellite, named Neil Armstrong: USA-320: 2022-01-13 2022-002CV Falcon 9 Block 5: Unknown Launched with USA-321, USA-322 and USA-323 on Transporter 3 Rideshare Launch. Likely the satellites were built by SpaceX based on the Starshield bus (based on Starlink Block v1.5 technology), were deployed by the US army.
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 ]
