Jupiter spacecraft encounters problem

NASA engineers are trying to determine what went wrong after a spacecraft circling Jupiter had another problem.

The space agency said on Wednesday that Juno detected a problem, went into safe mode and shut off its camera and instruments.

The spacecraft can communicate with Earth but its activities are limited.

It is the latest problem for Juno, which has been orbiting Jupiter since July on a mission to explore its poles, atmosphere and interior.

Last week, mission managers postponed an engine firing after valves in the spacecraft's propulsion system did not work as expected.

The delay means Juno will not swing close again to Jupiter until December.

The spacecraft made a close pass in August, beaming back pictures of the north pole.
