>> search for malaysia airlines 370's black box could wrap up in the next week. katy tur is live in perth, australia. good morning.
>> reporter: hey there, jenna. it could stop next week. it may not stop but it could. officials say they'll be wrapping up the most intense part of their search five to seven days from now because this is the area they have the most hopes for, the most focus on. it's the area they've been able to further refine those pings that ocean shields detected last week. if they don't find it in this area in the next five to seven days, they'll go back to the drawing board , have to figure out a new plan that could continue with bluefin 21 mapping a broader area underneath the ocean or it could have some other options unclear right now. so far in the search, it's gone about seven missions. it's on its seventh mission right now. it's completed six missions. nothing of note in the scan so far. blufin 21 has mapped a 5100 square mile radius. it is now or never in the next coming weeks.
>> katy tur in perth for us this morning. thank you.
