No, this doesn't mean that SpaceX's next spacecraft will be a starfighter from Star Wars. After all, these hypersonic grid fins make the Falcon 9-R look nothing like the almost iconic rebel ship. They do, however, still play a pivotal role, no pun intended. These fins are designed to help control and steer the rocket during its return trip from space. This will hopefully ensure that the craft will be able to land safely even on hard ground and survive to fly another day.
