From the SpaceX website….
The New Year got off to a great start for SpaceX with integration of Falcon 9 being completed a day ahead of schedule. Focus then shifted to the launch mount and erector and over the weekend, our team has made incredible progress.
Over the last few days, we flipped the launch mount base and installed it to the launch mount. We also installed the forward cradle and assembled the strongback in preparation for mating to the launch table base. Machining on the forward rail car assemblies was completed, with work on the aft rail car assembly quickly nearing completion, and a significant portion of the hydraulic systems were also installed.
Our next major milestone is rotation of the Launch Deck to vertical in order to initiate mating to the strongback, scheduled for Thursday, January 8th.
