On 8 April the ESA satellite Envisat stopped sending signals just weeks after its tenth year in orbit was celebrated. Over the past weeks ESA had attempted rigorously to reestablish communication and regain control over Enivsat. However all efforts seem to have been in vain - ESA officially declared the end of the mission on 9 May 2012. Envisat had already served twice as long as originally planned for.
