Mission: Submersible

The yellow tube Rutgers researchers pulled out of the Atlantic Ocean off the coast of Spain earlier this month may represent a sea change in the way we learn about the planet. The unmanned, information- gathering Scarlet Knight "flew" through the water without a propeller, becoming the first robot to cross the Atlantic. Scientists envision fleets of these unmanned gliders someday patrolling waters around the globe and reporting data about the undersea environment.
