Female spacewalker journeys to bottom of the ocean

Former NASA astronaut Kathy Sullivan created history by becoming the first US woman to walk on space and the first-ever woman to descend to the Challenger Deep. In 1984, Sullivan became the first American woman to walk in space with fellow NASA astronaut David Leetsma.

Guam: Kathy (Kathryn) Sullivan, the veteran of three space shuttle missions, is the eighth person to journey to full ocean depth.

She's made history in space, and now former NASA astronaut Kathy Sullivan has made history at sea.

68-year-old Sullivan, the United States' first female spacewalker, descended to the "Challenger Deep" in the Pacific Ocean on 7 June, becoming the first woman believed to have done so.

The first US female spacewalker has completed another feat becoming the first-ever woman to descend to the Challenger Deep, the deepest point in our oceans.

After these two challenges, she became the first human to have been in space and at a full ocean depth

She journeyed onboard 'Limiting Factor', a high-tech submarine that has visited the deepest point in all five of the Earth's oceans. She was accompanied by pilot Victor Vescovo.

In 1984, Sullivan became the first American woman to walk in space, conducting a three-and-a-half-hour spacewalk outside the Challenger shuttle with fellow NASA astronaut David Leetsma.
