无人潜艇将再次入海寻找失踪客机

A robotic submarine is set to resume its search for the missing Malaysian jet in the Indian Ocean one day after aborting its first mission.

The unmanned Bluefin-21 submarine was deployed on Monday night to start what was supposed to be a 16-hour search of the seabed for the Malaysia Airlines MH370.

But the mission was cut short after the submarine entered an area that exceeded its operating depth limit of 4,500 meters. U.S. navy officials say its built-in safety feature returned it to the surface and that it was not damaged.

Officials say data collected from the sub's six hour mission was analyzed and showed no sign of the missing plane.

The Joint Agency Coordination Center (JACC), which is coordinating the search, said the vehicle will be redeployed later Tuesday depending on weather conditions.

The submarine is being sent down nearly a week after sound locating equipment last heard signals that are believed to be from the missing jet's black boxes.

Locator beacons on the plane's flight recorder boxes emit signals so they can be more easily found, but their batteries only last about a month. It has been nearly 40 days since the jet went missing.
