Robotic salvage crews will be heading back to the spot where the Titanic sank in 1912 in hopes of finding the Marconi telegraph machine that was used to send distress messages the night the ship went down, killing more than 1,500 of the 2,240 on board.

According to National Geographic, The R.M.S. Titanic company wants to find out more about warning messages and distress calls that were made from the ship in hopes of discovering what actually may have occurred on that fateful night.

This new mission has also renewed the debate about access to the ship. Robotic salvage crews will try to avoid cutting into the ship and will attempt to gain access through an open skylight. Previous rules prevented any destruction of the ship’s structure, but The R.M.S. Titanic company was given permission, by a federal judge on Monday, to begin recovery efforts.

In the Monday ruling, Judge Rebecca Beach Smith of the U.S. District Court for the Eastern District of Virginia said, “will contribute to the legacy left by the indelible loss of the Titanic, those who survived, and those who gave their lives in the sinking.”

It's crazy to think that's been over a century since the ship sank, and there's still so much left to learn about the events that transpired aboard her that night.
