Robert Ballard is my hero. Dr. Ballard is a scientist, inventor, and a deep-sea explorer. He is most famous for discovering the wreck of the Titanic, 12,460 feet beneath the sea. The Titanic was the largest ship ever built in her time. She was as tall as an eleven story building and almost four city blocks long. The unique design of her hull was supposed to make her unsinkable, but in the middle of her first voyage the huge ship struck an iceberg and sank in the dark, icy waters of the Atlantic Ocean on April 15, 1912. Only 705 of the Titanic's 2,223 passengers and crew survived. Ever since the Titanic sank, people have been fascinated with the story and many have wondered about the location of the monster ship on the ocean floor.
Seventy-four years later, Bob Ballard led a team of scientists in a mission to discover the lost Titanic. Using Argo, the deep sea underwater robot craft Dr. Ballard developed, tethered to a research vessel called the Knorr, the team explored the region of the ocean where the ship went down. They tried for weeks to find the Titanic, but without any luck. Then Dr. Ballard thought of a new way to search. He knew that when things fall in deep water, they leave a long tail of debris, like a comet. He hoped that they might find a trail of wreckage from the ship that would lead them to the Titanic. He was right! With only days left to complete their mission, the team discovered a line of man-made objects that led them directly to the Titanic.
