The first American woman to walk in space, Kathy Sullivan, just became the first woman to reach the deepest point of the ocean

From 2014 to 2017, she served as the administrator of NOAA.

A tradition of science and expedition.
Sullivan is utilized to operating in high-pressure circumstances. During her 15-year profession with NASA, she flew on 3 space-shuttle objectives, including the one that released the Hubble Space Telescope.

After her days as an astronaut ended, Sullivan pursued her passion for oceanography and was designated the chief scientist of the National Oceanic and Atmospheric Administration in 1993.

According to Sullivans blog, visiting Challenger Deep subjects Limiting Factors hull to a pressure “akin to the weight of 291 jumbo jets or 7,900 double-decker buses.”.
The subs 3.5-inch-thick titanium-alloy hull is created to hold up against those pressures, and it has successfully done so throughout 5 previous trips to Challenger Deep. When, its the only submersible ever produced that can make that dive more than.

In 1978, she was one of the first ladies picked for the NASA Astronaut Corps, and she ended up being the first American female to stroll in space on October 11, 1984, outside the Challenger shuttle bus.

The 68-year-old copiloted a submersible called the Limiting Factor with the millionaire traveler and investor Victor Vescovo.
” Big Congratulations to her!” Vescovo tweeted after their successful mission..
The very first thing the 2 did after they got back to the surface was call the astronauts on the International Space Station.
” As a hybrid oceanographer and astronaut, this was an once in a lifetime day– seeing the moonscape of the Challenger Deep and after that comparing notes with my colleagues on the ISS about our impressive, reusable, inner-space outer-spacecraft,” Sullivan said in a declaration.

The challenges of getting to Challenger Deep.
Sullivan and Vescovo invested about 10 hours aboard the Limiting Factor, a two-person submersible developed by Triton Submarines and Caladan Oceanic.
It took 4 hours to come down to the crushing depth of 35,810 feet. They spent 1 1/2 hours on the ocean floor, then another 4 hours ascending.
” This is the most unique destination on Earth,” Rob McCallum, a founding partner of EYOS, said in a March declaration announcing the mission. “More people have actually been to the moon than to the bottom of the ocean.”.
This was Vescovos 3rd journey to Challenger Deep, which is more than 1 mile much deeper than Mount Everest is high.

Sunday marked the second time Kathy Sullivan made history.
Almost 25 years after she ended up being the very first United States lady to stroll in area, Sullivan ended up being the very first lady to ever reach Challenger Deep, the inmost point in our planets oceans. Shes the only person ever to do both.
Opposition Deep lies nearly 7 miles listed below the Pacific Oceans surface within the Mariana Trench about 200 miles southwest of Guam.
Sullivan is the 8th person in history make the dive, according to EYOS Expeditions, the business coordinating the mission.

At those depths, the water is perpetually dark and hardly above freezing. The pressure is a skull-crushing 8 tons per square inch– about 1,000 times the pressure at sea level.
