Retired U.S. Navy Capt. Don Walsh, best known for his daring dive to the deepest spot on Earth, nearly 36,000 feet below the ocean’s surface, has died at age 92. Walsh was a co-pilot of the Trieste bathyscaphe, a deep submergence vehicle acquired by the Office of Naval Research (ONR) in 1958. Two years later, on January 23, 1960, Walsh and Swiss engineer Jacques Piccard, son of the inventor of the bathyscaphe, became the first humans to descend into the Challenger Deep, located in the Pacific Ocean’s Mariana Trench. “ONR sponsored the Trieste, but it was then-Lt. Don Walsh who made the very daring decision to make the first descent into the deepest spot of the earth’s ocean. Walsh was a Navy officer, a submariner, an adventurer, and an oceanographer. To his family, we extend our deepest condolences and gratitude for allowing him to explore, and share his extraordinary experiences and knowledge with us,” said Chief of Naval Research Rear Adm. Kurt Rothenhaus.

The Space Sensor & Effects objective is to develop and experiment with key technology enablers that provide effective and resilient Intelligence, Surveillance, Reconnaissance & Targeting (ISRT) capabilities as affordable and proliferated space-borne sensors for littoral & maritime environments.
