NASA releases details of Titan submarine concept

February 10, 2015 - via NASA

Now that NASA has got the hang of planetary rovers, the space agency is looking at sending submarines into space around the year 2040. At the recent 2015 NASA Institute for Advanced Concepts (NIAC) Symposium in Cocoa Beach, Florida, NASA scientists and engineers presented a study of the Titan Submarine Phase I Conceptual Design, which outlines a possible mission to Saturn's largest moon, Titan, where the unmanned submersible would explore the seas of liquid hydrocarbons at the Titanian poles.

New SeeStar camera system allows researchers to monitor the depths without sinking the budget

February 2, 2015 - via Monterey Bay Aquarium Research Institute

In designing SeeStar, Kecy worked closely with Mechanical Engineer François Cazenave and Software Engineer Mike Risi. They ended up with a system that costs just under $3,000 in parts, but can operate as deep as 300 meters (almost 1,000 feet) for months at a time.

Is America's Dominance Below the Seas Coming to an End?

January 27, 2015 - via Center for Strategic and Budgetary Assessments (CSBA)

New technology is also likely to mitigate the limited endurance of non-nuclear undersea platforms. This could enable unmanned underwater vehicles (UUVs) to pick up some missions such as covert coastal surveillance and mining that previously required a manned submarine.

HMAS Success Supports Argo Program

January 27, 2015 - via Commonwealth Scientific and Industrial Research Organisation

The global Argo program relies on over 3000 autonomous drifting sensors from around the world routinely collecting sub-surface observations from the earth’s open ice-free oceans. Around 800 floats need to be deployed each year to maintain coverage and replace those with exhausted batteries.

Undersea Technologies Are Threat, Opportunity

January 23, 2015 - via Center for Strategic and Budgetary Assessments (CSBA)

"UUVs could take over some submarine missions such as close-in surveillance," Clark said. "Submarines could shift to more of a carrier mothership role, deploying UUVs." The vehicles could be armed, he suggested, with new lightweight anti-torpedo torpedoes, and would also be able to carry out reconnaissance and surveillance missions closer to shore.
