Nasa’s Opportunity rover is officially dead, the space agency has said, after it disappeared in a dust storm on Mars. Clearly emotional Nasa staff, standing in front of a life-sized replica of the rover, said they had not heard back from the rover and that the mission would come to an end. “I am standing here with a sense of deep appreciation and gratitude,” said Nasa associate administrator Thomas Zurbuchen, before he announced that the Opportunity mission is now considered complete.
