Nasa announcement to reveal the latest – and probably last – news on Mars Opportunity rover

Nasa is about to announce the future of the Opportunity rover, a pioneering robot that has spent years exploring the Martian surface. The space agency hasn't heard from its rover for eight months, when it disappeared and has not been heard from since. Now Nasa will send its last messages to the rover. But more than 1,000 have already been sent, with no reply from the rover, which is now facing a cold winter that will almost certainly kill it off if it doesn't manage to wake up. It's just as hard to say goodbye to Opportunity, as it was to its fellow rover Spirit, project manager John Callas told The Associated Press.
