Only ## satellites with a dedicated meteorological focus were deployed during 2017—less than ##% of ## spacecraft deployed during that year. It was also a drop from the number of meteorology satellites deployed in previous years. In 2016, the number of meteorology satellites deployed was ##, up...
Year: 2016
For all of the importance placed on meteorological satellites, they made up a very small part of the ## Earth observation/remote sensing satellites placed in Earth’s orbit during 2016. With a total of ## satellites, ## meteorological-focused satellites were launched or deployed in 2016 than in...

The majority of Earth observation satellites launched in 2016 were ##. Only ## of the ## Earth observation satellites had a launch mass of ### kilograms (### pounds) or more. The number of Earth observation satellites with a mass between ## and ## kilograms (##–## pounds) launched in 2016 was ##....

Weather and environmental satellites help humans understand and predict the atmospheric conditions of the Earth. National governments traditionally run these constellations, providing data for weather forecasting, climate modeling, and more. Weather agencies also provide data about life-threatening...
Year: 2015
The number of surface imaging satellites launched continued to grow in 2015. The sub-category dominated the greater category of Earth observation and remote sensing satellites launched in 2015, taking a nearly ##% share. The majority of surface imaging satellites literally provide a picture of...
