Meanwhile, two years into its intended 90-day mission, Spirit was in trouble again. What had now become known by some engineers as "the blue-collar rover", had broken one of her front wheels. After much deliberation (and comparison with faulty supermarket trollies), mission controllers decided the only option was for Spirit to drive backwards, dragging her broken wheel behind her. | |
