A team of scientists will launch an expedition to the Titanic next month to assess the deteriorating condition of the world's most famous shipwreck and create a detailed three-dimensional map that will “virtually raise the Titanic” for the public. The expedition to the site 2 miles 1/2 miles (four kilometers) beneath the North Atlantic is billed as the most advanced scientific mission to the Titanic wreck since its discovery 25 years ago. The 20-day expedition is to leave St. John's, Newfoundland, on Aug. 18 under a partnership between RMS Titanic Inc., which has exclusive salvage rights to the wreck, and the Woods Hole Oceanographic Institution in Massachusetts. The expedition will not collect artifacts but will probe a 2-by-3 mile (3-by-5 kilometer) debris field where hundreds of thousands of artifacts remain scattered. Some of the world's most frequent visitors to the site will be part of the expedition along with a who's who of underwater scientists and organizations such as the National Oceanic and Atmospheric Administration. The Titanic struck ice and sank on its maiden voyage in international waters on April 15, 1912, leaving 1,522 people dead.
