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. Scientists believe Titan holds important clues about the chemical processes that may have led to life on Earth.   A Drone Designed for an Alien World The Dragonfly spacecraft is roughly the size of a small car and features eight rotors that allow it to take off and land vertically. This design helps provide stability and ensures the mission can continue even if one rotor fails.  Unlike most drones, Dragonfly will be powered by...
