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.

搜寻人员星期二将继续动用微型无人潜艇，在印度洋搜寻马航失踪客机。一天前，这艘潜艇首次作业时被迫提前浮出水面。
 
“蓝鳍21”号无人潜艇星期一夜间开始进行预订16个小时的海底搜索，寻找马航MH370号班机，但是这艘无人潜艇进行搜寻的海域深度超过了其4千5百米的设计极限，因此缩短了作业时间。美国官员说，内装安全系统令其浮出水面，潜艇没有受到破坏。
 
官员们说，他们正在对这艘潜艇在六个小时作业期间搜集的资料进行分析，目前还没有发现失踪飞机的迹象。
 
联合搜寻行动协调中心表示，这艘无人潜艇将根据气候状况，于星期二晚些时候重新部署作业行动。
 
声波定位仪最后一次探测到据信来自失踪客机黑匣子的信号是在近一个星期前。
 
黑匣子的定位信标发出信号，以便更容易被找到，但是黑匣子的电池寿命只有大约一个月，而马航客机失踪已近40天。
