SpaceX engineers will have some changes to make on the company's new Falcon 9 v1.1 launch vehicle before its next mission, following lessons learned from its Sept. 29 demonstration flight.
A preliminary test of an innovative reusable-booster concept intended to hold down costs showed the need for more work after an uncontrollable spin apparently hampered pre-spashdown braking. The vehicle also aborted a planned restart of its upper-stage engine during the otherwise successful debut of the upgraded rocket.
