ISLE OF MAN, UNITED KINGDOM — Undersea explorer Victor Vescovo and Kathy Sullivan, the first American woman to walk in space, dived into the Challenger Deep last Sunday, according to a report in the New York Times.
The Challenger Deep is the deepest known spot on Earth.
It is roughly 10,902 to 10,929 meters deep.
Sullivan and Vescovo captured images of the deep sea while aboard the Limiting Factor, a deep-sea research submersible that can withstand 2,200 tonnes of pressure.
It is designed to travel into the deep oceanic trenches of the ocean called the hadal zone.
Once the pair ascended back into their ship, they called a group of astronauts in the International Space Station, which at the time was located around 409 kilometers above Earth.
