You are correct. My error. Hydrazine is used in the Centaur upper stage which is often used by ULA.
Hydrazine is not Hydrogen, and Hydrogen is not (effectively) storable. It shure is nasty stuff, though, I agree with that! The Draco series uses Monomethyl Hydrazine and N2O4 as the hypergolic components.

Centaur doesn't use Hydrazine/N204, it uses cryogenic LH2/LO2 and currently flies on the Atlas V. Delta IV uses it's own upper stage (DCSS) that also uses LH2/LO2 with basically the same Rocketdyne RL10 engine as Centaur.
SpaceX is having an environmental assessment done to build two more landing pads at the Cape for multiple FH booster and center core landings.
This is not surprising given that SpaceX has a Falcon Heavy animation that shows 3 cores landing.

FH is officially pushed into next year according to Shotwell. Not surprising after the F9 anomaly.

Nope not surprising at all but good to know. I'm actually a little surprised F9 will return to flight this year.
Hopefully. It take the FAA to approve a Return To Flight. If SpaceX can't figure what went wrong then that delays the process to "repair" and make the improvements necessary to prevent another anomaly. So the company might be ready, but the regulatory agencies might disagree.
I don't see a link to that announcement in your post or @Grendal post just above yours. Would like to read your source. Thanks!
No problem. Gwynne Shotwell gave a speech in Europe and the Space News European correspondent tweeted some of the highlights.
SpaceX hopes to fly again by November, delays Falcon Heavy
Happy to see that teaser photo of the FH! When it flies next year I hope people will start to come to grips with the reality that the SLS is DOA since it will cost at least an order of magnitude more to fly than the FH. See How I learned to stop worrying and love the big $60B NASA rocket
Looking at the photos of the SLS I just think, what a bloody waste! Lifting that huge rocket to orbit and then throwing it away.

It looks like SpaceX is focusing on March, April, or May for the Falcon Heavy launch. I'm guessing a bit but I expect that SpaceX was holding out for the F9 design to be fully vetted. Now we know that there is still one major upgrade still to come. You have wonder how powerful FH will be when it eventually uses 3 Block 5 cores.... That version should be as powerful as the proposed New Glenn from Blue Origins and SLS Block 1.

Lots of of good information on the Falcon Heavy. One of the better articles around.
Falcon Heavy – Rockets
Falcon Heavy – Rockets
So first flights with the current design to test the combination and then upgrade once Block 5 is proven?
And we have the first re-use to come as well...
Thanks for posting that link on Falcon heavy. I saw this gem on that article:
That would be wicked cool..
