I think it'll simply be a formal announcement of actually going ahead with the vehicle, i.e. not keeping it at some vague paper stage any more.

I think CONAE could do a dual payload mission on a Heavy, and a cheap price would probably get them onboard. But I have no information whatsoever regarding that and is pure speculation.

SpaceX president Gwynne Shotwell talked about Falcon Heavy dual payload back in April.

(starting around 33:15 into the program).

I'm assuming she wouldn't have mentioned it unless SpaceX had at least one potential customer that was interested.

Quite well done promo video. Here's looking forward to the 5th.

Looking at the end of the video,  the announcement has something to do with Falcon 9 Heavy

I'm really glad this video didn't come out a day later, or it might not have been real!

Maybe it was released from Kwajalein, where it was already April 1.
What kind of wastrels would dump a perfectly good booster in the ocean after just one use?

"Falcon Heavy". No "9" any more.

cheers, Martin

I suspect that they will drop the Falcon 9 title as well and just go with Falcon eventually. Especially if they drop Falcon 1e and switch to Merlin 2 engines for Falcon 9.

What do we think about that picture of the FH outline recovered from the teaser video and looking like the 1st stage is noticeably longer than the existing F9 (spacexmystery.gif)?

Where can I see this picture?
Need to see it before starting to think.  ;)
But it should be possible to have a longer 1st stage due to better T/W at liftoff.

It may look longer, but if you actually scale and overlay the image on the FH page over that one, you can see they match up almost precisely. I think it's just an optical illusion - a black silhouette showing no boundaries between nosecones, interstages and engine sections, etc.

In any case their VTS3 test stand support tower doesn't appear to support a taller stage right now. Needing it for F9 stage acceptance firings right now for extended periods of time I don't see them messing with that any time soon.

Comparison of a quickly stiched together picture (multiple screenshots from the video) and the FH pic from the website:



So yes. Its the same. (ratio in pictures was kept btw)

But it should be possible to have a longer 1st stage due to better T/W at liftoff.

27 is a *lot* of engines. I'm thinking their approach from the start would be to baseline sufficient T/W at liftoff even if 1 engine dies right away (worst case that's basically 2 engines out if it happens to one of the strapons). That would preclude really stretching the stages and maxing out the propellant load.

Acceleration wise, think more of a Titan IV lifting off, not Delta IV Heavy. I could be completely off the mark, though.

Did a quick search and didn't see an answer to this...Any ideas on altitude of/velocity of FH strap ons when they are "jettisoned?  they should have a higher chance of success of recovery shouldn't they?

Is it certain that the strap ons will be jettisoned? Or will the three cores operate together as a single stage like Rus M? (Of course the cores might be separated after staging to allow for single recovery if this proves worthwhile.)

mmm..I always visualized the strap ons burning at a slightly higher thrust then the core ..(not too much dues to stresses) then they fall off and core burns then the usual staging..but that adds complexity..so maybe it will act as single stage...but I'm assuming the cores are recoverable...I hope on  tuesday they get specific and not.."The Airforce is giving us a $100 M to launch a FH demonstrator, thank you..and good night..."  they better have some fancy videos ;)

Wel i think it would be that, however you never know they might have something in the background like a FH look alike, you know a couple of F9's laid out to look like a FH
