Meteor-2-21/Fizeau is the twenty-first and last in the Meteor-2 series of Russian meteorological satellites . ILRS Mission Support Status: Satellite Laser Ranging (SLR) tracking support of this satellite was discontinued in October 1998. What makes Meteor-2-21 distinctive from the other meteorological satellites
189-412: A collision. Roscosmos later confirmed that the satellite had suffered a decompression of its thermal control system following what is presumed to be a micrometeoroid impact. Following the incident, the spacecraft was automatically switched into a low-power mode and ground operators worked to restore the satellite's orbit and orientation. By 25 December 2019, the satellite had resumed controlled flight, but

In addition to its regular payload, Meteor-2-21 carried a unique Fizeau Retro Reflector Array (RRA) for Satellite Laser Ranging applications. Several of the satellites have begun to break up and create debris. #16 broke up in 1998 after a propulsion failure. #18 broke up

India has polar orbiting satellites as well. The United States Department of Defense 's Meteorological Satellite ( DMSP ) can "see"
630-447: A number of changes over its predecessors in support of its mission to gather data for weather forecasting and climate monitoring. The MTG satellites are three-axis stabilised rather than spin stabilised, giving greater flexibility in satellite and instrument design.

The Meteor-3M series of satellites was to be an advanced series of polar orbiters with one 1.4 km resolution visible channel and a ten-channel radiometer with 3 km resolution. Initially four Meteor-3M satellites were planned, however due to financial difficulties only one was launched. The first Meteor-M satellite, Meteor-M No.1 ,
1134-718: Is a type of Earth observation satellite that is primarily used to monitor the weather and climate of the Earth. Satellites can be polar orbiting (covering the entire Earth asynchronously), or geostationary (hovering over the same spot on the equator ). While primarily used to detect the development and movement of storm systems and other cloud patterns, meteorological satellites can also detect other phenomena such as city lights, fires, effects of pollution, auroras , sand and dust storms , snow cover, ice mapping, boundaries of ocean currents , and energy flows. Other types of environmental information are collected using weather satellites. Weather satellite images helped in monitoring

Geostationary weather satellites orbit the Earth above the equator at altitudes of 35,880 km (22,300 miles).

India also operates geostationary satellites called INSAT which carry instruments for meteorological purposes. Polar orbiting weather satellites circle
2205-521: The U.S., Europe, India, China, Russia, and Japan provide nearly continuous observations for a global weather watch. As early as 1946, the idea of cameras in orbit to observe the weather was being developed. This was due to sparse data observation coverage and the expense of using cloud cameras on rockets. By 1958, the early prototypes for TIROS and Vanguard (developed by the Army Signal Corps ) were created. The first weather satellite, Vanguard 2 ,
