As of 5:52 p.m. ET (7:52 a.m. on Monday, local time), James Cameron has arrived at the Mariana Trench‘s Challenger Deep, members of the National Geographic expedition have confirmed.

His depth on arrival: 35,756 feet (10,898 meters)—a figure unattainable anywhere else in the ocean.

Reaching bottom, the National Geographic explorer and filmmaker typed out welcome words for the cheering support crew waiting at the surface: “All systems OK.”
