Astronaut Edward H. White II, pilot for the Gemini-Titan 4 (GT-4) spaceflight, floats in the zero-gravity of space during the third revolution of the GT-4 spacecraft on June 3, 1965. White wears a specially designed spacesuit. His face is shaded by a gold-plated visor to protect him from unfiltered rays of the sun. In his right hand he carries a Hand-Held Self-Maneuvering Unit (HHSMU) that gives him control over his movements in space. White also wears an emergency oxygen chest pack; and he carries a camera mounted on the HHSMU for taking pictures of the sky, Earth and the GT-4 spacecraft. He is secured to the spacecraft by a 25-feet umbilical line and a 23-feet tether line. Both lines are wrapped together in gold tape to form one cord. Astronaut James A. McDivitt, command pilot, remained inside the spacecraft during the extravehicular activity (EVA). Astronaut White died in the Apollo/Saturn 204 fire at Cape Kennedy on January 27, 1967.

These stunning images reveal the remains of a more than century-old sunken ship that has been preserved beneath freezing Lake Superior. The ship looks almost exactly the same as it did the day it sunk beneath waves all those years ago. At 60 meters long (approximately 198 feet), the «Gunilda» sunk after it struck some rocks and was not saved. Now, these stunning images have been captured 107 years after the sinking when a small group of divers revisited the vessel. (Photo by Becky Kagan Schott/Caters News Agency)
