BBC: Meteosat-10 was launched into geostationary orbit yesterday by the European Organisation for the Exploitation of Meteorological Satellites. Since the launch of its first satellite in 1977, the Meteosat program has been providing Europe’s forecasters with continuous meteorological observations from space. The primary instrument aboard Meteosat-10 is an advanced visible and IR imager, which “builds its pictures of evolving meteorological systems, line by line, by spinning across the field of view,” writes Jonathan Amos for the BBC. The satellite can track cloud movement, changing temperatures, and other phenomena.
