ESA declares end of mission for Envisat | SpaceRef – Your Space Reference
Just weeks after celebrating its tenth year in orbit, communication with the Envisat satellite was suddenly lost on 8 April. Following rigorous attempts to re-establish contact and the investigation of failure scenarios, the end of the mission is being declared.
A team of engineers has spent the last month attempting to regain control of Envisat, investigating possible reasons for the problem.
Despite continuous commands sent from a widespread network of ground stations, there has been no reaction yet from the satellite.
