Elon Musk Shows Off Near-Complete Falcon Heavy Rocket (newatlas.com)

Eloking quotes a report from New Atlas: SpaceX's Falcon Heavy rocket has been a long time coming. The successor to its Falcon 9 and the vehicle hoped to carry humans to Mars, this booster will be one of the most powerful ever. And we've just gotten our best look at it yet, with CEO Elon Musk tweeting out photos of an almost complete Falcon 9 Heavy in the hangar ahead of a planned maiden launch next month. The Falcon Heavy is essentially three Falcon 9 first stages rolled into one, with a second stage sat atop the middle one. The nine engine cores in each first stage work together to provide thrust equal to eighteen 747 aircraft, making it the most powerful rocket currently in operation and the most powerful since the Saturn V rocket last lifted off in 1973. In a series of tweets, Musk revealed that when the Falcon Heavy does lift off for the first time, it will do so from the same pad used by the Saturn V rocket at NASA's Kennedy Space Center. Musk has said recently that the Falcon Heavy will carry his own cherry-red Tesla Roadster as its first payload, but as an earlier tweet professing his love for floors has shown, it's not always easy to tell how serious he is about such matters.

      This said, and with all respect for Musk and the people at SpaceX, I don't believe rockets can deliver the space revolution we're hoping for. The rocket equation puts a hard limit on their capabilities. And if some hypothetical very energetic propellant is discovered, having large quantities of it fly around and perhaps fall back to the surface in case of accidents would be risky.

      Moreover, rockets are still very very expensive. Even reusing all stages of the rocket won't make them cheap enough for mass adoption. I believe a different technology is needed to really open space travel to humanity. Space elevators offer a possible solution, with rockets taking over once the payload is outside Earth's gravity well. Or some even more exotic technology that doesn't exist yet.

      Of course, rockets are available now, and they're good enough for exploration. Every time somebody like SpaceX makes them just a bit cheaper, huge new opportunities for discovery open up.

    For example, if mankind were to use "Boring Company" technology to cut an access tunnel up to a point near the 5,980-metre peak of the mountain, then use Hyperloop technology to provide a platform on which a rocket could be placed, put a stack of Solar City panels in the vicinity [to power the super-conducting magnets used by the maglev technology and perhaps also to synethsise the Methylox fuel, then essentially he has most of the components needed for a launch system that grabs another order of magnitude of cost savings/efficiency gains - because potentially the vehicle itself could do away with a potentially significant amount of fuel.

    I took a quick look at the most recent launch, CRS-13, in which at 6km of altitude, the vehicle had achieved a speed of 938km/h, a little shy of MaxQ. I would have to concede that we are still a long way short, engineering-wise, of being able to achieve that even with a maglev track in an evacuated hyperloop tunnel. But Musk is all about continual, iterative improvement.

    I would be the first to concede that all I've done here is borrow ideas postulated by science fiction writers for many years now: but if you go back to the 1950s and 1960s and look at the writing of Heinlein-era sci-fi writers, rockets that landed on their tails and took off again were a staple fare. It took real life 60-70 years to catch up, but SpaceX did it. With our rate of development increasing, what I outline here could be as little as 20-30 years away.

Using a maglev, or similar propelled "cart", to provide a first stage launch vehicle for a spacecraft isn't a new concept though - as you say, there are numerous 20thC sci-fi works that depict this approach, almost certainly based on the technique used by the V1 and V2 rockets in the 1940s - so removing the hyperloop tunnel from the equation and just using a souped-up version of the maglev might eventually be a viable approach. It really depends on whether the fuel and mass savings from that initial phase of acceleration is significant enough to offset the costs and technical complexity (e.g. potentially non-vertical launch trajectory) of operating the first stage.

From what I can see, there are only 4 per side booster, and they really don't look that big. Will that truly be enough? By what kind of margin? I'd almost expect the rocket to tear itself apart once those two boosters kick in.

      All of the rocket motors fire at once, and they don't do full power right at startup. So I think the idea is to ease in to it right at liftoff.

      The SRB on the Space Shuttle was full power as soon as it was lit and it only had a problem... once.

      Actually no, the 27 Merlin 1Ds will be starting sequentially, in balanced pairs, much like was done with the Saturn V or the space shuttle. Once the engines are all running, it will throttle up to max, the systems will check the engines to make sure they're all performing properly, then the launch clamps will be released. I don't know the exact sequence, obviously, but shortly after launch the engines on the center core will be throttled deeply to conserve propellant, while the engines on the side boosters run at full power.

      Basically, with a rocket, you want your engines operating at max thrust just prior to launch as that is your final check on them. As you fly, you also need them at max throttle because of how much propellant you still have on board. As you burn your propellant, you then start throttling the engines back to keep the g-forces within the limits of what your rocket (and payload) can handle.

      Once the side boosters separate, the center core will throttle back up again, and continue the mission as though it were a single stick Falcon 9, just going faster and higher than it would have had it flown the mission solo.

      The SRB on the Space Shuttle was full power as soon as it was lit and it only had a problem... once

      Yes, and that was by design as they had to lift the contents of the ET at launch. The fuel grain of the SRBs was cast such that the thrust of the SRBs would change through the mission, and basically fall off as they got towards the end. So yes, in fact, you can control the thrust profile of a solid motor, by controlling its chemistry and physical layout.

    Sorry, but in Space, navigation is all about gravity and dealing with it. Yes, you're weightless when not under thrust, but that doesn't meant hat gravity isn't having an effect. To reach Mars from Low Earth Orbit, you need about 4.3km/s of Delta-V. That is you need to be able to increase your speed by 4300m/s. That takes propellant and energy.

    Right now, the standard Falcon 9 has just enough power to put a geostationary communications satellite into its transfer orbit. To go from LEO to Geostationary Transfer Orbit takes about 2.5km/s. In the case of Intelsat 35E, just getting the payload to a (super synchronous) GTO meant there wasn't enough propellant left to perform a landing, so the mission was flown expendable.

    Anyhow the whole point here is that the FH lets you impart enough velocity into a larger payload that it will make it to Mars. In the case of the demo mission, it's only launching Elon's roadster, which is pretty lightweight, so there is plenty of margin left, but in the case of a larger payload, they'll need every bit of performance they can get.

    coming back and not colliding against anything else are way more worrisome

    Actually the bigger worry would be *not* colliding with anything, and drifting off into deep space. At both ends of the trip, you want to collide with the atmosphere of your target so that you don't need to expend the propellant to brake yourself into orbit. In between? Well, to quote the Hitchiker's Guide. "Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space."

    The probability of running into anything out there is somewhere between 0 and nil, it's far more likely you're going to suffer a failure of your equipment than run into something, especially once out of LEO.

    The point I was trying to make was that being fast in space is very easy and that it isn't a matter of lack of power availability. A different story is how you are planning to manage all the speed/acceleration aspects. If you want to reach certain speed inside the Earth atmosphere and let you go, even the slightest increase would be associated with a relevant energy consumption. On the other hand, if you want to do it in outer space, the story would be completely different. Your 4.3 km/s, similarly to pretty much any other thing, are meaningless out of context: very difficult against gravity + friction vs. extremely easily against nothing.

    You say that, but have you done the maths on this? Musk has, there was a story earlier this year when Musk stated flying halfway round the world could be done for the same cost as a full-price economy ticket. Once he gets the reusability thing down, a large part of the cost will then be fuel, if the fuel can be made cheap enough, space travel can be made somewhat affordable. Maybe not an everyday thing for most people, but maybe something you could afford to do once a year.
