SpaceX rolled out and raised its first Falcon Heavy rocket on Pad 39A on Thursday (Dec. 28) for a fit check. From Jeff Foust of SpaceNews on Twitter:
Fit check today, static fire test in early January, launch maybe later in the month.
From Spaceflight Now on Twitter (time lapse video of the rocket being raised here):
The Falcon Heavy is now in place at launch pad 39A at the Kennedy Space Center to begin testing before its maiden flight next month.
It is real! Look at that SpaceX Falcon Heavy. View from Playalinda National Seashore vista.

This is really fascinating stuff here. And hopefully very historic.
The FH wiki states that the rocket was re-lowered to the horizontal position on Dec. 29. Was this planned or was it due to an unforeseen issue?
Also, is SpaceX planning on recovering any/all of the first stages on this first launch attempt?

From what I understand, this rollout was only intended as a pad fit check, but whether it was lowered and returned to the HIF early or as scheduled is something only SpaceX knows.
SpaceX intends to recover both side-mounted boosters and the core, the earlier at Landing Zone 1 (where there are now two pads, LZ-1 and LZ-2) and the latter at sea on a droneship.

From SpaceX on Instagram:
With more than 5 million pounds of thrust at liftoff — equal to approximately eighteen 747 aircraft at full power — Falcon Heavy will be the most powerful operational rocket in the world by a factor of two.

Are there any details available on the structure that connects the three Falcon 9 rockets together or any structural changes to the rockets so they can stay strapped together until separation?
There does not seem to be any significant structure visible to that could keep 1.7 million lb thrust each side attached. Of course I do believe SpaceX have designed something capable I am interested in more detail but cant find anything online covering this.

SpaceX is preparing to conduct its first Falcon Heavy static fire test today (Jan. 11). Per Spaceflight Now:
SpaceX does not reveal details of its testing program, but today's window for the hot fire is believed to run 1-7 p.m. EST (1800-0000 GMT).

Why does it need to be more open? They aren't under any rules or law to be more open. It takes time and resources to provide daily statuses.

Even a little tweet?
Elon Musk communicates about his big rocket eventually blowing up on its first flight and when testing time comes, a deafening silence? Really? Well, I hope these people will never be in charge of the space program, manned or unmanned, unless the communication obligations are the same as NASA's.

Fueling of the Falcon Heavy rocket in Florida has started as vapors appear near SpaceX's new rocket. The Falcon Heavy's first hold-down test-firing could occur shortly.

The vehicle was erected on the pad today, but at last report, the static fire was expected no earlier than Saturday evening (Jan. 13) Monday afternoon (Jan. 15).
The static fire is expected to be about 15 seconds long.

For someone more familiar with operations at the cape, what considerations and requirements need to be set for the engine test fire time window?
Robert Pearlman Editor

The static fire test of SpaceX's Falcon Heavy rocket is not expected today, and we have not received a new target date for the hold-down firing at pad 39A.
...launch preps at nearby pad 41 are underway for an Atlas 5 mission scheduled for liftoff Thursday evening, with rollout of the rocket to the launch pad scheduled for tomorrow. A Falcon Heavy static fire at pad 39A is not expected to occur during the Atlas 5 countdown, a ULA official said today, due to shared safety, security and ground infrastructure between the two adjacent pads.
Based on that, the Falcon Heavy static fire is expected no earlier than Friday, but the target date for the hold-down engine firing remains uncertain, and we'll share information as we confirm it.

All up to SpaceX to determine it. Crew rest or alertness may be a priority. But there are no real driving factors for a specific time.

SpaceX's Falcon Heavy static fire (and launch) will wait until after the federal government shutdown ends. Per the 45th Space Wing, via Florida Today:
Due to the shutdown removing key members of the civilian workforce, the 45th Space Wing will not be able to support commercial static fires taking place on KSC.

Thirty three years ago today, I had the privilege of being at the press site for the shuttle program's first (fully classified) DOD mission, STS-51C/Discovery. Today's test brought back many memories.

The test fire seemed to last only for about 8 seconds. Was the test cut short?

SpaceX did not release how long the static fire was planned to last, but as the test has been declared a success, it apparently met the parameters set by the company.

I just bought two tickets for the rocket garden. That way if we cannot make the date I am out a reasonable (sort of) sum.
It says it comes with a two day admission ticket, one for the launch and the other is good for 90 days either before or after the launch.

Is this basically the same as the "Banana Creek Viewing" which is shown adjacent (just SE) on Google Maps?

I'm going down for the Feb. 6 launch date. The backup date is the 7th. If for some reason it doesn't launch on these two dates due to a non-mechanical problem such as weather, does anyone know how soon a third date would occur?

The 45th Weather Squadron's L-4 forecast predicts an 80 percent chance of acceptable conditions on Tuesday (Feb. 6), with the main concerns being liftoff winds and thick clouds.
If the launch slips to Wednesday, the chances decrease slightly to 70 percent acceptable conditions due to another fast moving fontal system moving into northern Florida.
