Video Time may be up for America's plucky Opportunity rover that has trundled across the surface of Mars for more than 14 years.

During a press conference on Wednesday, NASA officials said that the robot had been caught in a massive dust storm encircling a quarter of the planet, and this had blocked the probe's solar cells from charging its battery. The device has almost certainly entered low-power mode, with all systems shut down except for a trickle of energy keeping the bot's main clock ticking.
