"Nasa's Curiosity mission has ground to a halt on Mars after a glitch forced the $2.5 billion (£2 billion) rover to terminate all of its science experiments.

Mission team members say the inter-planetary science lab can no longer beam data stored in Curiosity's memory banks back to Earth, effectively rendering it useless until the issue is resolved."
