SpaceX is working closely with Ensign Bickford Aerospace & Defense Co., supplier of key components of the Flight Termination System (FTS) that will be used on Falcon 9, to complete testing of the FTS hardware and provide final data to SpaceX and Air Force Range safety officials for review and acceptance.
Certification of the Falcon 9 FTS and subsequent range availability will put the first Falcon 9 test launch towards the latter half of the anticipated March-May window, with the first attempt no earlier than May 8, 2010.
