SpaceX's Falcon Heavy has launched 11 times, all successfully, and is based on the Falcon 9 rocket rated to ferry people into orbit. NASA already certified Falcon Heavy to launch its most expensive robotic missions, such as the Europa Clipper mission, which launched last month.

NASA announced that it has selected SpaceX to provide launch services for its ambitious Dragonfly mission that will place a rotorcraft lander at Saturn's moon of Titan as part of its New Frontiers Program.

NASA's Dragonfly mission to Titan will launch on a SpaceX Falcon Heavy in 2028, exploring prebiotic chemistry and searching for biosignatures.
