SpaceX Falcon 9 Relatively Cheap Compared To NASA's New Pad
An anonymous reader writes with this excerpt from Motherboard.tv:
"As debate over the future of spaceflight rages on — and as the axe all but falls on NASA's mission back to the moon and beyond — the successful launch of SpaceX's Falcon 9 two weeks ago proved at least one of the virtues of the private option: it's a heckuva lot cheaper than government-funded rides to space. In fact, the whole system was built for less than the cost of the service tower that was to be used for NASA's proposed future spaceflight vehicle (yup, the service tower is finished, but the rocket isn't, and the whole program may well be canceled anyway)."
CEO Elon Musk spoke recently about some of the ways SpaceX finds to cut costs in the construction of their rockets.
It's great that they cut costs and all, but what about those pesky corners? I'm all for a private space industry, but NASA has a pretty darn good track record of performance to back up their expenditures. Will these cheaper options be more efficient, or just cheaper?
It's simpler and cheeper than the shuttle, but it replaces all of it's important roles. That makes it a better solution overall. It's also cheeper than all the other rockets NASA has available.
As has already been pointed out, Ares I and Falcon 9 are very similar in capabilities.
But furthermore - if Falcon 9 (or some other launcher for that matter) can launch a comparable mass to LEO, in several launches (we're good at rendezvous by now...), as one launch of the heavy Ares V (that's the rocket you're thinking of), and if it can do it still much cheaper (despite needing several launches) - then why wish for Ares V? A rocket which would be launched very rarely, hence driving the costs even more up btw.
In contrast, a launcher in the league of Falcon 9 is quite universal.

... except the defunct Saturn V and the Russian N-1
Also Energia (and too bad its heaviest variant, Energia Vulcan, never had a chance; that would be some sight). Not so old, and part of it still flies (Zenit). Though even if it would be possible to ressurect it, there's no funds to do it and no reason to direct them (Ares V has the same problem - what's wrong with rendezvous in orbit using few cheap launches?). Plus politics: Russia wouldn't want to depend on Ukraine, so they're building new heavy launcher - Angara; heaviest variants of which aren't quite in the league of Saturn V, N-1 or Energia, but are halfway there. Might be useful for Mir 3, I guess.

Was recovering satellites (hence also building a vehicle that can do that by wasting most of its mass that's put to LEO on airframe) ever shown to be economically justified? Why no commercial launch companies and satellite operators seem to interested in it now?
Plus, we already have launchers that can put the same amount as Shuttle into LEO. And they are cheaper, they rule the commercial launch market. SpaceX is likely to push the market into even lower prices.

"What Elon Musk is doing is similar to the assembly line process Henry Ford brought to the automotive industry."
What about the Russians and the Soyuz ships? They've built over 1700 launchers so far, from the 60s to present... surely that's got to count as "assembly line process"?
"Evem early in the game, the solid booster system was known to result in a cost increase of 60% per pound into orbit."
Can you provide a reference for that? I've been told by an actual rocket scientist that solid fuel rockets are significantly cheaper than liquid fuel rockets, especially for the boost phase, where thrust-to-weight matters more than propellant efficiency.
I've also seen inflation-adjusted figures for Saturn V vs STS, and the Saturn V was vastly more expensive. Now, they only flew about two dozen Saturn V's, so they never had a chance to develop economies of scale, but it's not like the STS is a huge win in that department either. The Saturn V also had a much greater total lift capacity, so this may be apples-to-oranges in the first place.
Certainly, liquid fuel rockets have a number of advantages, but I haven't seen anything to suggest cost is one of them.
(Note that I'm not saying the STS SRBs were an overall win. Good design theory won't save a badly run program. I just question the idea that's it's *because* they were solid rockets that costs were high.)

Not sure what they're doing for test sites now, but early on SpaceX tested (sometimes destructively though probably not intentionally) firing chambers and other hotloud technology on a cattle ranch a mile or so east of their McGregor TX site. I've seen (as well as not seen but tripped over) rusty pieces of kaboomage while hunting down my own far more modest but adequately errant rockets during Dallas Area Rocket Society high-power launches. It's obviously not a top dollar test range. I'm thinking they probably had to move elsewhere when stuff got big and bad enough that the vehicles and/or pieces could travel 5 miles downrange before doing some high speed post hole digging. It's 5 miles to Bush's ranch at Crawford.
Not to be out-cheaped, DARS flies smaller stuff at a site that's loaned free, near Rockwall TX. On the land there's a cement pad that used to be a garage floor. On the pad there's marks that used to be some of early Armadillo's H2O2 exhaust. Of the source of the exhaust, I found no traces. Found plenty of my own though.
Maybe that's why they and Blue Origins favor Texas. There's so much land that you can always find some cheap.

You forgot the part where SpaceX didn't do any R&D. Instead, they used old technologies developed by... wait for it... NASA.
And, SpaceX didn't build a launch facility, instead they used.... NASA's.
No wonder SpaceX didn't spend much, they didn't do anything new.
There is no "-1 offended" or "-1 you don't agree with me" mod options for a reason.
I have to bow to his awesome ability to spin the facts. He's saying "how about we won't do what we signed the contract to do, but still get the money..." and three different people post to say "sure, that sounds reasonable."
A normally government contracts works like this...
Contractor: We will build x and do y for 100 million! ...Time passes... ...Time passes... ...Time passes..
Government: Great that's a really low bid, your hired!
Contractor: We had problems, the new cost is 150 million.
Government: Well, these things happen, no problem carry on...
Contractor: OK well it's done but it doesn't do Y yet.
Government: Well we really sort of need it to do Y.
Contractor: Sure we understand, but it will cost another 100 Million?
Government: Well... alright then..
Contractor: Alright done, but well it does do Y but sometimes it also does X?
Government: Ah well screw it, works good enough! Here's a bonus!
So you see if this company can get everything that was to be done in 3 flights done in just 2 then that's a shockingly good thing. If you haven't noticed we have a nice shiny space station and no damn way to get people up to it without Russia's help. It would, kind-of be nice to have a private entity available you know... If SpaceX can figure out ways to save money and "everyones" time while providing the same service why should we punish them for that? They can make extra money, that's OK for a business to do, as long as the job gets done properly and the business is on the hook for any fuck up.
But you're right NASA does have the right to force them to do all 3 even if the third is pointless. But honestly what the hell is the point and how is it going to encourage cost cutting and cheaper rates in the future? How will that build a good business relationship with SpaceX?
If you hire me to install a network and I tell you it will take 3 days and it only takes 2 are you going to make me sit on my ass that third day? Well I guess you probably would but if I ever did business with you again in the future, unlikely, I'd ream your ass.
