The largest potentially payload to LEO/above since Saturn V.

(And the cheapest to (re)launch hands down.)

Finally, the TE no longer looks small and empty, as it did with just a Falcon 9 on it.

So ... how long has this been waiting on by those here? Good Christmas for you all?

So, as she stands right there... is it the most powerful rocket since the Saturn V? Or at least the Shuttle?

She hasn't flown yet, but...
most powerful liquid rocket since Saturn V (7+mlf).  Shuttle had more total thrust (approx 5mlf for FH v 6+mlf)

I never thought we would see this day. FH is real.  :D

Energia was the most powerful rocket since Saturn V and still is. Unfortunately, it flew only two times, in 1987 and 88 and had a LEO capacity of about 100 mT and . More than Falcon Heavy. Space Shuttle could only get 28mT to LEO. In pure payload numbers, Shuttle is more comparable to F9 B5 expendable (not quite but close) than FH. But of course Shuttle could launch payload and astronauts at the same time and return the orbital stage to earth, which is quite some different game than Falcon Heavy.

Perhaps we need to see a launch/success ... for it to be ... real?

But for sure ... not a paper rocket.

Crud.  I just left the cape this morning after ending a 10-day vacation trip there. What time was the pad appearance? Sitting in Sanford airport waiting for my flight and read about this just a few minutes ago.  sooooo close....

Yeah--that's where I was going with my answer--need to have an operational rocket (why I left out Energia, though at least she/they flew a couple times as a test).  And of course thrust v performance, etc etc.
btw, nice hat, SG1962...

This is coming together at the pad a lot faster than I remember the inaugural Delta IV Heavy.

If it hot fires/launches well, has adequate performance, and lands all ... it may well be a very capable LV, and the first cluster vehicle to achieve what all the others could not - feasibility.

Yes DIVH works but it's a nightmare in many ways to get on/off the pad. Angara has been many decades in the making. Both don't have a huge number of flights.

If it does go well, and does so within two years again ... many heads will be turned. Congrats SX, you did it much faster than I thought you would.

Here's betting on a smooth inaugural flight.

Indeed.

(Energia also was a costly, touchy ... iffy thing.) F9/FH seem to be more about "utility" thenthan "shock and awe".

Thanks, it's festive for this FH season ;)

Space Shuttle could only get 28mT to LEO.

If we think of the whole orbiter (gross lift-off weight 110 tonnes) as the "payload" then STS got a lot more into LEO. But that is of course a question of how you define payload. However, I think we can consider the orbiter as a spaceship the same way that we consider Dragon a spaceship, and then indeed STS got 110 tonnes into LEO. The fact that the orbiter was reusable supports considering it as "payload".

I agree with you on the examples you gave.

But dont forget Soyuz. With more than 1000 flights over many iterations, its in an entirely different league than any other launcher in the world. And its a cluster vehicle. I would say it counts in terms of feasibility ;-)

(then vs. than)  I don't think that was the one you meant to use there.  But it fits, too, so I'll allow it.   :)

STS was also able to transport crew along with payload - so not exactly apples to apples when comparing to FH. Perhaps FH with a Dragon 2 - then STS wins on crew # and payload capacity and FH wins on throw distance...

Relax, shuttle huggers, there are still records it holds that aren't broken. :) Come back in a few years, though...  ;D

Neat comparison images, source: http://www.forum-conquete-spatiale.fr/t17713p250-spacex-lancement-falcon-heavy-janvier-2018#408836

Astronauts are going to need a bike to get from one end of the CAA to the Dragon 2.
That's going to be quite a walk...

No. There is L2 info if you're a member, but short answer is no.

No, consensus seems to be that they will be waiting until after Zuma (Jan 4)
