On June 7, astronaut and oceanographer Kathy Sullivan, who was the first American woman to walk in space in 1984, became the first woman and the fifth person in history to descend to the Challenger Deep. Sullivan is now the only human who has walked in space and reached the deepest point in the ocean.
About:
The Challenger Deep is the deepest known point in the Earth's oceans, with a depth of 10,902 to 10,929 m.
It is located in the Western Pacific Ocean, at the southern end of the Mariana Trench near the Mariana Islands group. This location is in the ocean territory of the Federated States of Micronesia.
The depression is named after the British ship HMS Challenger, whose expedition of 1872–1876 made the first recordings of its depth.
