The thermosphere (or the upper atmosphere) is the height region above 85 kilometres (53 mi), while the region between the tropopause and the mesopause is the middle atmosphere ( stratosphere and mesosphere) where absorption of solar UV radiation generates the temperature maximum near an altitude of 45 kilometres (28 mi) and causes the ozone layer.
Coordinated Universal Time ( UTC) is the primary time standard globally used to regulate clocks and time. It establishes a reference for the current time, forming the basis for civil time and time zones. UTC facilitates international communication, navigation, scientific research, and commerce. UTC has been widely embraced by most countries and ...

MET was formerly called Ground Elapsed Time (GET) prior to the Space Shuttle. The International Space Station (ISS) does not use an MET clock since it is a "permanent" and international mission. The ISS observes Greenwich Mean Time (UTC/GMT). The shuttles also had UTC clocks so that the astronauts could easily figure out what the "official ...
