A new study of data from NASA’s bountiful Cassini mission shows that Titan’s largest methane sea, Kraken Mare, is at least 1,000 feet – 300 meters – deep near its center. That’s plenty of room for a future robotic submarine to explore. Source: https://earthsky.org/space/titans-largest-sea-kraken-mare-is-1000-feet-deep…
