Video: SpaceX Falcon F9R 1000m Flight with fins.
SpaceX has released this video of Falcon 9 Reusable (F9R) during a 1000m test flight at their rocket development facility in McGregor, TX and was their first test that included a set of steerable fins that provide control of the rocket during the fly back portion of return.
According to SpaceX the "fins deploy approximately a minute and 15 seconds into the flight, and return to their original position just prior to landing. The F9R testing program is the next step towards reusability following completion of the Grasshopper program last year. Early flights of F9R will take off with legs fixed in the down position, however we will soon transition to liftoff with legs stowed against the side of the rocket with leg extension just before landing. Future test flights of F9R at our New Mexico facility will include higher altitudes, allow us to prove unpowered guidance and to prove out landing cases that are more flight-like."
