1st woman to reach deepest point in ocean

Former NASA astronaut Kathryn Sullivan, the first American woman to conduct a spacewalk, has become the first woman to reach the deepest known point in Earth’s ocean. In a submersible, she descended nearly 11 kilometres to the bottom of “Challenger Deep” in the Mariana Trench. Sullivan was accompanied by Victor Vescovo, an entrepreneur and deep-sea explorer, who funded the mission.
