LOS ANGELES (AP) — After recovering from a computer problem, the Mars rover Curiosity is sidelined again, further delaying the restart of science experiments.
The latest complication occurred over the weekend when the six-wheel rover entered safe mode after experiencing a software file error.
Curiosity remained in contact with ground controllers, but it can't zap rocks, snap pictures or roam around until the problem is fixed. Rover team members had expected to resume activities Monday, but they now have to wait a bit longer — perhaps until the end of the week.
