As I'm writing this, the search is still underway for the submersible watercraft Titan, which has been missing in the Atlantic Ocean since the weekend after it went down to search the wreckage of the Titanic.
The U.S. Coast Guard told media outlets Tuesday night that a Canadian aircraft had been able to detect noises from beneath the surface, but given the Titan's limited volume of oxygen, the search was racing against time.
Meanwhile, NASA's Marshall Space Flight Center in Huntsville has detailed its role as OceanGate developed the Titan submersible craft, reports AL.com's Lee Roop.
Marshall said the center and its employees did not test or build the Titan but that it consulted with OceanGate on materials and manufacturing processes.
