    Because I can't really understand - how we can have a rocket fully built and launched successfully for far less bucks than NASA spends? How is it possible - after years of spending billions of dollars we have a single stage flight (incomplete first stage) and a second stage mockup? And meanwhile, spending just several hundred millions of dollars produces a cheap rocket capable of delivering astronauts in orbit?
    Excellent question, especially since Ares I was originally supposed to be using 'off the shelf' components to keep costs down. I suspect part of the answer come back to politics and NASA having Congress on its...shoulder making decisions based on anything but efficient engineering.

    That's the difference between a commercial company operating on the profit motive verses a government agency that relies on contractors on cost-plus contracts. Reportedly, NASA spent $400+ million for the Ares I-X. Also reportedly, SpaceX has spent about $400 million to date developing the Falcon 1 and Falcon 9 (including all of the engines and related systems) as well as the Dragon capsule. Oh, and don't forget the cost of the support infrastructure at the Cape and Kwajelein. While the Dragon is a long way from being ready to carry people (Musk says 3 years from when they receive the contract), that is an astounding accomplishment. One of the ways they kept their costs under control was to do almost all of the work in-house. About the only system they out-sourced was the Flight Termination System. SpaceX has done all of this while keeping the number of employees as low as possible. I've read that Lockheed-Martin has 1000 engineers working on the Orion capsule alone up in Denver. SpaceX has fewer than 1000 employees, total.

    This achievement exposes just how incredibly huge the bloat inherent in using a combination of cost + contracting and design by committee. the Ares program got to inherit all of the huge bloat from the shuttle as well. Ares had to start to pay for facilities it will only need when it is operational before it passed PDR.

    SpaceX used a procure as needed approach to the buildup of infrastructure. something that has saved them hundreds of millions of dollars in upkeep during the development cycle.

    Ah, we got some congressional reaction:

    http://www.spacepolitics.com/2010/06...lcon-9-launch/

    Sen. Hutchison
    Make no mistake, even this modest success is more than a year behind schedule, and the project deadlines of other private space companies continue to slip as well.
    Sen. Shelby:
    Belated progress for one so-called commercial provider must not be confused with progress for our nation’s human space flight program

    I like how they complain it's a year late when according to the Augustine commission the Ares I is 6-8 years behind schedule.

    They have no other choice. They are responsible for their districts and the fact Falcon 9 is maybe a faster way to send people into space doesn't change the fact there will be job loses.

    We're talking about jobs. We're not talking about whether Falcon 9 is better or not. In the end, even the ISS was (is) just a jobs program.

    Musk said Sen. Bill Nelson, D-Fla., called him Friday afternoon to congratulate SpaceX on the successful launch.
    "SpaceX joins an elite group of companies who have successfully developed launch vehicles with such a great capability," said Rep. Dana Rohrabacher, R-Calif. "But the fact that SpaceX was able to accomplish this in such a short time with such a small budget changes the paradigm of spaceflight."

    Rohrabacher is one of very few Republican members of Congress enthusiastically supporting President Obama's decision on NASA.

    "The ambitious flight test with four major targets for first stage, stage separation, second stage, and orbit insertion showed how capable our nation's commercial space launch providers are," Rohrabacher said in a statement. "The fact that the Falcon 9 system aborted the first attempt, and SpaceX was able to recycle and launch within two hours shows that industry is ready to take the lead in our routine orbital space missions."

  8. #38
    We wouldn't of course. IMO Nelson words should be taken more seriously, because he didn't support the new plan in the beginning.

    Good points. There are literally 10's of thousands of people working on the space shuttle launch system. That has a major effect on launch costs. So much so that the cost per launch of the space shuttle has ranged from $250 million to $750 million depending on the number of launches per year largely because of that veritable standing army that has to get paid no matter how many launches there are in a year.
    Elon Musk also had some informative comments about how they were able to keep costs down at SpaceX by keeping overhead low:

    The Rocketeers. How a Visionary Band of Business Leaders, Engineers, and Pilots is Boldly Privatizing Space.
    by Micael Belfiore
    HarperColins, 2007
    Musk had identified five major drivers of launch vehicle costs and had set about bringing each one of those down. The first, and perhaps the biggest, was overhead. Looking around the Main Building I could see for myself that Musk ran a tight ship. He had fewer than a hundred employees, including all the engineers, machinists and associated support staff like the receptionists, administrative assistants, and a public relations officer."We are an extremely low-overhead company," said Musk. "If we simply handed our blueprints to a Boeing or Lockheed, I think the price would at least double if not more."
    "There was the rocket itself, with three major components contributing to its cost: engines, structures (the actual body of the rocket as well as fuel and oxidizer tanks), and avionics - the sophisticated computers and software that controlled the other components to guide the rocket through the air to space and into orbit.
    "And then there was the launch operation. Musk laughed as he told me how a Lockheed Martin representative boasted to him of his company's "lean" launch crew: only three hundred people. "Now what are those people doing? I can't tell you." Falcon 1's launch crew? Twelve to fifteen people sitting in a custom-made trailer at the launch site."
    The Rocketeers, p. 175.

    Keep in mind too that SpaceX is not at the stage of conducting manned launches. According to their estimates it would take another $300 million to man-rate their Falcon 9/Dragon system:

    Is It Safe?
    The first company with a plan—and a rocket—to send humans to orbit answers the existential question.
    * By Michael Milstein
    * Air & Space Magazine, May 01, 2009
    "For SpaceX, the only upgrades required for Dragon to carry people are the Apollo-style abort-and-escape system, seats, and a full life support system. It will cost about $300 million to go from transporting cargo to transporting people, most of it for the escape system and the test flights the human-rating rules require. SpaceX has already negotiated the finances of this step with NASA."

    Sen. Shelby:
    On a slightly on unrelated note, Hutchinson is actually a Senator from my state. They just seem to be sore that things aren't going their way, a year behind schedule isn't that bad in regards to the aerospace industry, two examples would be Ares I (6-7 years) and the Space Shuttle was at least four years behind schedule and it was hoped to be ready to boost Skylab into higher orbit.

    In regards to Shelby, if a certain rocket seems to be the only thing that's going to be carrying astronauts in the next few years, than progress for that commercial provider is closely related to that space program. If the bird had exploded on pad and the subsequent launches were failures than within the US what would that mean for manned spaceflight? People would most likely be more hesitant of commercial rockets and would prefer instead to go with the traditional rocket with various sub-contractors

    The cancellation or end of every program results in job loss, in short job loss is inevitable, it should not be used to prevent us from moving forward. Part of the oath of the engineer is "the obligation to serve humanity by making the best use of of Earth's precious wealth". I've said this before but one of the problems of the shuttle program was the high amount of workers required for a launch to happen, so job loss might actually be a good thing even if we did pursue a Constellation plan.

    One of the problems with Constellation is that it seems to have been partly designed around preserving as many of those jobs as possible, so if it went ahead I wouldn't expect a lot of efficiency savings. And frankly if anyone wishes to advocate Constellation they need to explain in nice simple terms how with so many more resources than Space X NASA has achieved so little with Ares I.

    Ares I is even further from that. And they managed to accomplish that with only several billion $!

    I did that a little while ago. Ares was being built by commission on a budget not large enough to support basic R&D which causes the price to rise as things go along as they figure out the rocket as they build it and require design changes to other vehicles as they find out things about the rocket.

    If Ares continues I don't know whether or not this problem will be fixed. If Ares doesn't continue I still don't think this problem will be fixed, and Obama's mystery HLV and lack of proper funding leaves this same fundamental problem.

    "Far less bucks?" Apparently NASA supervisors have other agendas besides successful missions, which add greatly to the cost. This happens often in the private sector also, but sometimes the private CEO has authority, and the will to squelch these private agendas, thus saving big bucks. Neil

    One of the reasons is that a larger organization suffers from more overhead, i.e. more people doing essentially unproductive paperwork. (It is sometimes claimed that private organizations are inherently more effective to public bodies, but the experience with large corporations proves that this is not a deciding factor). Corollary: in 30 years SpaceX will be as ineffective as NASA today.

    Also: do you think that all the Asian countries building ICBMs would be able to afford them if the actual development cost was anything near the NASA prices?

    Seconded. Another problem with Obama's HLV is that it was not clearly defined what will be the goal of this vehicle. If there's no goal, there is nothing to measure the result against. Because normally you have a goal, which dictates specification, which dictates design. What will happen here is that something will be built, and the specifications will be adjusted to fit what was built. And then the goal will be restated accordingly. So (exagerating) you will start with a vehicle for delivering 200 tons to LEO and end with a vehicle delivering 20 tons to LEO -- for 10x the original budget. (I would like to be wrong here. Really.)

    Sorry but are you suggesting that the answer to the question how did NASA produced so little with so many resources is that they needed more resources? Or are you suggesting that Space X didn't have to figure things out as they went along and make alterations? NASA has spent billions on Ares I and all they have to show for it is launching a glorified mock up last year. Do you actually think NASA has spent the Constellation budget it has already received well or wisely?

    Both. The latter does make quite a bit of difference in SpaceX's favor.

    1) They've only received ~40% of the funding they originally stated they would need back in 2004. Bush never allocated 100% of the funding the original cost estimates requested. Not all the money they've received has been spent on Ares I. Some has been spent on Orion redesigns which drove the cost up above original estimates. Even with rising costs they've still never gotten 100% of the 2004 funding estimate they need.

    2) They haven't spent some of the money they have received wisely.

    The problem is two-pronged in this case. But with Obama's budget I still haven't seen anything that prevents this problem from continuing in the future.

    Exactly. With no defined goals or specifications the vehicle is free to keep changing specifications and design if the original doesn't cut it and keep driving up costs and launch prices.

    I would have more respect for Obama's HLV proposal if they had already created a design for one. But from what I read his proposal was almost as much of a surprise for Bolden and NASA as it was for the public. So NASA may not have known about this mystery HLV. It would probably be cheaper to just use Ares V or something similar as the HLV Obama is looking for. It's a finished design and we can estimate costs with it.

    First off; a LOT of the money spent on Ares has been in the successful design and testing of the Pad Abort System. This set of rockets accelerates to ~12gs while keeping the capsule in an orientation that allows the astronauts to possilbly survive it; then rotates the capsule, deploys parachutes and successfully lands. This feat has been neatly ignorred - it was one of the most challenging aspects of the entire Constallation program.

    Musk says he has 'ideas' about how to build a pad abort system; but are these even being fleshed out?

    Secondly, a full-up Ares first stage has been ground tested. The parachutes have been tested and the capsule is well into the final stages of engineering; including a full capsule sans internal elements - much further along than any Falcon Human-rated system.

    Third, most of the delays have been related to delays in the shuttle program - a cargo problem delayed ARES I-X testing by almost six months.

    Finally - SpaceX's accomplishment for so little money is truly remarkable. It has been much more expensive than Musk extimated; but still impressivelty fast and cheap and involved lots and lots of uncompensated overtime. A bricklaying firm I know has captured most of the local market. They don't have any employees over the age of thirty-five; they don't pay benefits for more than two-thirds of the hours worked; and they run anyone out-the-door who fails on any of several production metrics - metrics extremely difficult to achieve for anyone over the age of forty.

    According to the Planetary Society the new plan is good because NASA will now choose between three competitors - Ares need not apply. Which means at least two times as many efforts will lead to failure as will succeed. It is a good old free market approach - but what do brick layers do between the ages of thirty-five and sixty-seven?

    As far as I know Apollo was capable of pad abort too. So is Soyuz, and that system has saved a crew. Maybe there's something I'm missing, but why would that system be so hard and expensive to develop today?

    They had to develop a totally new design for Ares. Apollo's escape system is not powerful enough for the Orion or to get a good distance away from the Ares I SRB. I imagine they also want it to be more advanced than the Apollo escape system, which is the last escape system NASA ever built before the Orion LAS.

    SpaceX will need to develop its own as well. So far they estimate it will cost around $300 million to develop one for the Dragon. At least for now. In the future the price might turn out to be lower than expected or higher than expected. An escape tower for the Dragon could have a more benign flight profile since the Falcon 9 rocket wouldn't blow up as violently as the Ares I.

    Actually Musk is 38 and the launch abort system on the Dragon sounds to be rockets implement into the belly of the capsule that use the same fuel as the Draco thrusters. But you do have a point that SpaceX doesn't have to pay any pensions and I think Kamaz may be right about how in 30 years SpaceX's productivity might go way down.

For that reason, I have greater respect for the Delta IV Heavy maiden flight partial failure than I have about the complete success of Ares I-X. The former verified so many more systems and subsystems for subsequent flights, even though the flight was a partial failure. It enabled the very next flight to be completely successful. Ares I-X style approach leaves too many questions in the open until later incremental flights. More $$$ to be spent.
    Excellent point, and worth mentioning again.

    Government verses private industry: What can $500 million buy?

    According to Musk, SpaceX has spent about $500-600 million to date. They've developed the Falcon 1 and Falcon 9 boosters including all of the engines, tanks, flight controls, and avionics. They've developed the Dragon capsule to the point that the first COTS test will take place this summer including all of its systems. They've developed all of infrastructure to build, test, assemble, and launch their rockets and capsule including mission control, software development, test stands, integration facilities and launch pads, both at the Cape and at Kwajelin. Their total number of employees just reached 1000 recently.

    Total SpaceX expenditures?
    - The $350M-$400M mentioned the other day was for Falcon 1 and Falcon 9 rockets.
    - Dragon, facilities, pad, etc add up to about another $100M-$150M.
    - So total SpaceX expenditures till now adds up to around half a billion dollars.
    - Includes money from NASA, private investment, deposits from customers, etc.


    For $500 million, NASA conducted a single test flight of the Ares I-X. For another $500 million, they built the Ares I Mobile Service Tower.

    Better quality video (not as complete though) that includes video feed of the Falcon 9 second stage in the final seconds of orbital insertion and video of the second stage shutdown and announcement of the Dragon mockup entering orbit:

    http://www.spacex.com/multimedia/videos.php?id=51

    Awesome! I can just imagine astronauts starting to float inside a Dragon capsule at the end of the video!
