On April 10, 1912, the Titanic set out from England on its first voyage, or trip. It was heading to New York City. At the time, the Titanic was thought to be the world’s most luxurious and safest ship. Many people believed it was unsinkable.
But four days later, the ship hit an iceberg. In less than three hours, the Titanic sank. About 2,200 people were on the ship, and only about 705 survived.
The final resting place of the Titanic was a mystery for years. Then, in 1985, an explorer named Robert Ballard discovered the wreck. It was about 12,500 feet underwater. Interest in the Titanic rose again around the world.
Since 1985, about 250 people have explored the Titanic. They traveled in small underwater vehicles called submersibles. Some of these explorers took photos of the wreck. Many brought up items that survived the sinking.
