無人潛艇將再次入海尋找失蹤客機

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.搜尋人員星期二將繼續動用微型無人潛艇，在印度洋搜尋馬航失蹤客機。一天前，這艘潛艇首次作業時被迫提前浮出水面。

“藍鰭21”號無人潛艇星期一夜間開始進行預訂16個小時的海底搜索，尋找馬航MH370號班機，但是這艘無人潛艇進行搜尋的海域深度超過了其4千5百米的設計極限，因此縮短了作業時間。美國官員說，內裝安全系統令其浮出水面，潛艇沒有受到破壞。

官員們說，他們正在對這艘潛艇在六個小時作業期間蒐集的資料進行分析，目前還沒有發現失蹤飛機的跡象。

聯合搜尋行動協調中心表示，這艘無人潛艇將根據氣候狀況，於星期二晚些時候重新部署作業行動。

聲波定位儀最後一次探測到據信來自失蹤客機黑匣子的信號是在近一個星期前。

黑匣子的定位信標發出信號，以便更容易被找到，但是黑匣子的電池壽命只有大約一個月，而馬航客機失蹤已近40天。
