NASA has started building a groundbreaking spacecraft called Dragonfly , a nuclear-powered drone designed to explore Titan , the largest moon of Saturn. The mission is scheduled to launch in July 2028 and could become one of the most ambitious robotic exploration missions ever attempted.   Dragonfly is not a traditional space probe. Instead, it is a rotorcraft that works like a large drone with multiple rotors. This design will allow it to fly from one location to another on Titan’s surface, collecting data and studying different environments.
