In a first, autonomous robotic submarine to circumnavigate the globe

The article reports on the upcoming mission of Redwing, an autonomous underwater robotic glider designed to circumnavigate the globe, marking the first time an autonomous underwater vehicle (AUV) will complete such a journey. Developed by Teledyne Marine and Rutgers University as part of the Sentinel Mission, Redwing will launch from Martha’s Vineyard, Massachusetts, and follow a route similar to Ferdinand Magellan’s historic circumnavigation, covering approximately 73,000 kilometers with stops at key global locations such as Gran Canaria, Cape Town, Western Australia, New Zealand, the Falkland Islands, and potentially Brazil before returning to Cape Cod. The mission is supported by organizations including NOAA, the UN Ocean Decade, and the Marine Technology Society. Redwing is a next-generation Slocum Sentinel Glider, notable for its ultra-long endurance, capable of over a year of persistent ocean monitoring. It can operate at depths up to 1,000 meters and is equipped with enhanced battery capacity and space for up
