Not that I think it will, but still, the mere fact that they have considered it deserves me munching a little crow, I still say they won't. This is clearly a Muskism. BUT STILL FALCON SUPER HEAVY They'd need to build a whole new core to be able to handle even higher thrust loading. Core recovery would be virtually impossible, too; the upper stage would basically just be for circularization. More thrust than the Saturn V, though. 7 minutes ago, CatastrophicFailure said: Meanwhile, SLS is still... Interesting... Apollo LM was right around 16 tonnes...

If some want to launch an oversize payload say an lunar lander as we discuss in that tread an larger fairing can be developed, max expendable payload to LEO might well require an reinforced second stage. As we know no customers ask for this so why should spaceX develop it. If you plan of doing an honeymoon on the moon, other requirements like the lunar lander will give spacex good time to develop an larger fairing and bill you for it Quote Link to comment Share on other sites More sharing options...
IncongruousGoat Posted February 5, 2018 Share Posted February 5, 2018 The FH live stream (which, mind you, is unlisted and not due to start for another 19 hours) has 2,300 viewers already.

This is why i don‘t get the whole hype around this thing. This Launcher, composed of essentially flight proven components will mostly launch some Comsats and at best a discovery class probe, and people behave like its the second coming of christ.

XB-70A Posted February 5, 2018 Share Posted February 5, 2018 Some fresh views of the pad took about an hour ago. And by far my favorite of all: It was already full of spotter today, I can't imagine what it will be tomorrow! Quote Link to comment Share on other sites More sharing options...

Obvious response, and no any who has played KSP know that don't make sense, use of parachute is pretty kerbal however. Honorable mention to Valentina who was dropped from LKO in an MK2 capsule, parachute burned up during reentry but she landed and could walk away from it. Extra bonus for the mothership.

But it is the first coming of Falcon Heavy. And its return to Earth occurs not once, but three times, only a few minutes after launch. Meanwhile, it's twenty centuries later and we're STILL waiting for Christ's boostback, entry, and landing burns. no disrespect to any religion meant; the above is purely satire 21 minutes ago, Exploro said: So this whole time the FH test was a front for SpaceX to send our extraterrestial tamed-racing driver back to the stars...with wheels no less.

Because things are happening. They may only be smol things, baby steps in the grand scheme and what not, but they’re some of the things that were “promised” to all of us decades ago, that many of us had already given up on, and now finally, after all this time, here comes this guy who says, “I’m gonna do the thing” and then unlike everyone else, he actually goes out and starts doing it! This is the attraction of NewSpace to people, while old space is still plodding along saying “yeah, maybe in 30 years, also we have no funding” or repeating the same boring, if necessary, stuff over and over. Tomorrow represents real, tangible innovation. Like someone said back a page, we’re finally making all this cool lunar landing speculation on a real rocket that’s actually sitting on the pad right now. I can only imagine that maybe this is what it felt like say in 1967 or 68, when space nerds really had some hope for what was to come.
