You’re seeing data streamed from a Lightfish autonomous surface vehicle (ASV) designed and built by Seasats. This particular vessel was launched from San Diego on January 7th, 2025, with a goal of crossing the Pacific Ocean. It made a short stop in Hawaii before continuing on its way.

Lightfish are solar-powered ASVs designed to carry various payloads, acting individually or in meshed constellations. Science, defense, and commercial customers load them with sensors to collect data and execute missions more affordably, effectively, and safely than crewed vessels. Lightfish are only 10 feet long and 350 lb, but capable of operating in full-ocean conditions. This resilience, combined with their low unit costs, makes Lightfish affordable, low-logistics tools for persistent ocean missions. They have been proven in operations with the U.S. Navy, scientists, and through a recent successful voyage from San Diego to Hawaii.

This Lightfish is outfitted with a standard sensing and communications package, including cameras, Iridium and Starlink satellite communications, and a weather station measuring temperature, wind speed and direction, and humidity.
