NASA has approved the upcoming Titan Dragonfly mission to move to the next phase of development, known as "Phase C," where they work on the final mission design and fabrication. We won't hear the final cost and schedule until 2024, but the agency is still planning a launch readiness for July 2028. Dragonfly will build on the success of the Ingenuity helicopter, flying a nuclear-battery-powered rotorcraft on Saturn's largest Moon.
