Dr. Kathy Sullivan is having a very big year. Not only is she the first woman to have ever walked in space, but now she is the first woman to go to the deepest point in the ocean. Both are pretty amazing fetes for anyone to accomplish.

Sullivan, who is a member of the US Astronauts Hall of Fame, and now works for the National Oceanic and Atmospheric Administration (NOAA), recently reached Challenger Deep which is, according to Wikipedia, the deepest known point in the Earth's seabed hydrosphere.

Sullivan completed three historic space shuttle flights in 1983, and became the first woman to walk in space on Oct 11, 1984. And she is only the 8th person to ever reach the bottom of Challenger Deep. Her co pilot on this journey was undersea explorer Victor Vescovo, who tweeted out a photo from the expedition, which you can see below. The two are only a few of the people in history who have actually reached the bottom of the ocean, which is pretty amazing in itself.

Not only did they travel seven miles down into the ocean, they also made a call to the International Space Station while they were at the Challenger Deep site. The trip was coordinated by EYOS Expeditions, and the call was a first as well. Read more about her amazing adventures in space, and in the ocean from NPR. Congratulations to Dr Sullivan, who has proved to be an inspiration and a pioneer to millions around the globe!
