SpaceX founder just posted on Twitter a link to the above YouTube video and the tweet:
Completed rocket static fire with all systems green this time. Launch window opens in 10 days.
That would put the first launch of the upgraded Falcon 9 on September 29. Not from Cape Canaveral, but from Vandenberg Air Force Base.
The SpaceX facility at the Cape's Pad 40 was upgraded during the summer with a new erector to handle the taller and more powerful Falcon 9. The first launch from there will be an SES-8 communications satellite, currently scheduled for sometime in October.
