     Working in the control room of the salvage vessel (求助打捞船) Seaprobe at two o'clock one morning

in 1977, Robert Ballard was shocked by a large piece of equipment that crashed onto the deck just three

feet above him. The ship shook with the force of an explosion (爆炸). A drill pipe and its attached equipment

broke and fell into the Atlantic, abruptly ending the explorer's test to find the RMS Titanic.

     "I lost a lot of credibility with sponsors (赞助商), who had lent the $600 000 worth of equipment" for

the 1977 exploration. "It took me eight years to recover from that." But recover he did, despite doubt from

other scientists, failed money-raising efforts and other unfortunate happenings.

     After the Seaprobe failed, Ballard says, "I had to come up with another way to search for the Titanic."

He returned to work as a U.S. Navy officer. At a time the geologist cut a deal with Navy officials: He would

offer his expertise (专业知识) if they supported the development and testing of Argo, a camera-equipped

underwater robot, and allowed him to use it for exploration.

     The Navy sent Ballard and Argo to search for Thresher and Scorpion, two submarines (潜水艇) that

sank during the 1960s. Those vessels lay in waters not far from the Titanic. After having found the Scorpion

in 1985, Ballard began to look for the lost liner Titanic. And two miles down, in the dark sea at 49°56' W,

41°43' N, he found it.

     The oceanographer, who later found the German battleship Bismarck and the liner Lusitania, says simply,

"Failure and success are bedfellows, so I'm ready to fail."

     Ballard's worked in the University of Rhode Island's Graduate School of Oceanography. Students will join

him on his latest research-exploring ancient trade routes in the Black and Mediterranean seas.
