A new National Geographic documentary, “Titanic: The Digital Resurrection,” highlights scientists analyzing the 3D model and their discovery of an open steam valve.

More than 700,000 images of the shipwreck, taken from submersibles, have produced a photorealistic 3D digital model.

RMS Titanic Inc. plans to use remotely operated vehicles to capture high-resolution images of the famed shipwreck.

A seven-foot model of the RMS Titanic is seen on display in the Noble Maritime Collection's Navigation Classroom. The museum is located on the grounds of Snug Harbor Cultural Center in Livingston.
