First American woman to walk in space reaches deepest spot in the ocean
NASA astronaut Kathy Sullivan made history this weekend by becoming not only the first woman to reach the deepest point in the world’s oceans, but also the first human to have been in space and at full ocean depth of about 7 miles. Sullivan marked the occasion by making a phone call from the submersible’s mothership, DSSV Pressure Drop, to speak with the NASA astronauts on the International Space Station .
Sullivan is now the eighth person to reach the bottom of the Challenger Deep, which is at 36,200 feet below the surface. The first two who accomplished the feat, Don Walsh and Jacques Picard, reached it in 1960, while Hollywood director James Cameron descended in 2012. The LF can operate at depths that place the equivalent of 2,200 tonnes of pressure on the submersible’s frame. Built by Triton Submarines in Florida, Limiting Factor is the first submersible to repeatedly descend to the deepest points of the ocean. The ISS, by contrast, is circling the Earth at an altitude of about 254 miles. Two astronauts were recently delivered to the space station aboard the recyclable Falcon 9 rocket.
Vescovo’s Caladan Oceanic is dedicated to deep-ocean research. Following last year’s Five Deeps Expedition, Vescovo is leading the current Ring of Fire Expedition. It will bring former astronauts like Sullivan as well as paying “civilians” to some of the deepest points in the oceans.
