Walsh (foreground) inside the Bathyscaphe Trieste submarine shortly before a select team of scientists, engineers and naval officers helped to send them 7 miles below sea level to explore the deepest part of the earth's oceans known as the Challenger Deep, a depth and area previously unreached that is located at the southern end of the Mariana Trench in the western Pacific Ocean near Guam on January 23, 1960.

Don Walsh (foreground) and Jacques Piccard in the sphere of the Trieste as they checked the instruments panels prior departure for the dive. Because it is loaded with instruments, the space available inside of the sphere is of approximately 38 inches in diameter and less than six feet in height. Space is equal to that of an ordinary household refrigerator and so is the temperature which is usually about 42 degrees when the sphere is 13,000 feet below water. For the dive to the bottom of the Marianas Trench, Lt. Walsh and Jacques Piccard remained in this extremely small space for almost 9 hours (8 hours and 40 minutes).? - John Launois KEYWORDS: Bathyscapth, Bathyscaph, Bathyscap, Bathyscaf, Bathysphere.
