The Scarlet Knight, named for sponsoring Rutgers University’s mascot, is a cruise-missile-shaped autonomous ROV that was launched off the New Jersey coastline on April 27. If all goes according to plan, the Rutgers team will recover it off the westernmost coast of Spain right around Christmas day. That happy event would mark the first successful underwater crossing of the Atlantic by an unmanned vehicle. At the mission website, you can track the robot’s position using Google Earth, monitor her battery status, and follow the team’s navigation blog.
