Metop-A spacecraft status
Metop-A completed its operational mission on 15 November 2021, after achieving a lifetime in orbit of over 15 years. This was followed by the de-orbiting operations in line with debris mitigation standards. The traffic light chart and associated footnotes below represent the last status of each subsystem and instrument prior to Metop-A's removal from operational service.
