In 1985, Oceanographer Bob Ballard went searching for the most famous shipwreck of all time. Explorers, including Ballard, had been looking for the ship for years without luck. But on this voyage, the team had Argo, a deep-sea vehicle with a remote-controlled camera to help with the search. For days, the team pulled Argo across the ocean floor and found nothing. They were beginning to lose hope. Then, on September 1, something appeared on their video screen. It was a piece of the Titanic! Find out what happened next in Rediscovering the Titanic.
