Can Commercial Space Tech Get Off the Ground? 133
coondoggie writes "While NASA's commercial partners such as SpaceX and Orbital have made steady progress in developing space cargo transportation technology, they have recently fallen behind their development schedules. Combine that with the fact that the most critical steps lie ahead, including successfully launching new vehicles and completing integration with the space station, and you have a hole that will be tough to climb out of. Those were the two main conclusions of a Government Accountability Office report (PDF) on the status of the commercial space world this week. The GAO went on to say that after the planned retirement of the space shuttle in 2010, NASA will face a cargo resupply shortfall for the International Space Station of approximately 40 metric tons between 2010 and 2015."
Speaking of SpaceX, reader Matt_dk sends along an update on the company's Falcon 9 flight efforts. "Six of the nine first stage flight engines have completed acceptance testing and all nine flight engines are on schedule to complete acceptance testing by mid-July."

This means more failed rockets, more wasted time, and more material costs. This will work against their limited monetary resources, as well as give the international community more time to actually decide to do something about it.

The main problems are that NASA because of "security reasons" can't give out a lot of the taxpayer funded research that would help these companies get off the ground. So, what took NASA many years to do doesn't have to be reinvented by a private company.
The bigger problem with "security reasons" that commercial companies like SpaceX has is with things like ITAR export restrictions; these are the same regulations older slashdotter might remember from the late 90s, where strong encryption was regarded as a munition as people were tattooing encryption code to themselves along with the text "this man is a munition." [treachery.net] A recent example is with SpaceX's delayed launch of Malaysia's RazakSat satellite [hobbyspace.com]:
Technicians discovered the satellite and the Falcon 1 upper stage rocket share a nearly identical vibrational mode, which could set up a damaging resonance. SpaceX is bound by ITAR restrictions from assisting with any technical problems on the foreign-owned payload, so the company delayed the launch to add some vibration isolation equipment between the rocketâ(TM)s upper stage and the payload adapter.
"The easiest thing would actually be to make some adjustment to the satellite . . . but that's not allowed," Musk says.
Also, if anything, reinventing from the ground up is a big part of why SpaceX has been able to get costs as low as they have. Instead of designing their rockets to satisfy the politicians' fetish for spreading assembly over key congressional districts across the country and the engineers' fetish for maximizing performance at the cost of all else, SpaceX has been able to design their system from the get-go to minimize production costs, minimize the size of their ground crew (SpaceX Falcon I just needs something like 20 personnel at the launch site, instead of the 100 or so needed for EELVs), and maximize potential reusability.

There are plenty of compelling reasons to go into space:
Growth of the species - Humanity is expanding in population very quickly. Eventually, assuming that holds, the planet will reach the point where sustaining that population is impossible, even with advances in technology. Your choices, then, are either to limit/reduce the population (sterilization, limitations on childbearing, war, disease, organized extermination, etc) or expand off the planet. The second option seems a little more friendly and ethical.
Survival of the species - There are several things which can cause the population to be essentially wiped out. Asteroid impacts, war, deadly pandemics, biowarfare (which I personally consider the greatest threat at the moment), and so on. It's possible that some may survive these things by digging deep underground, but I doubt enough infrastructure and population will survive to maintain society as we know it. The best long-term solution I can see is to expand off-planet and establish self-sustaining colonies. You don't keep all of your company's data and server hardware in one location, do you? The same should hold with humanity as a whole.
Additional resources - This fits with the first point. There is only so much stuff available to us on this planet. Whether we use it all up, or decide to preserve it, we will eventually reach the point where we can't use any more. What are we to do at that point? Well, I see a whole bunch of stuff sitting up in space just waiting to be used. Now before anyone starts, I am not promoting the "strip earth bare and trash it, then move on" approach. Instead, I'm promoting the "let's make use of all those barren rocks out there so we don't have to trash earth" approach.
Overall, unless we're going to take that self-ridiculing, defeatist position that humanity should draw down into a little ball and live the remainder of its existence shut in from the universe as a whole, like a pathetic and sick individual afraid to even get out of bed*, we will have to go into space eventually. It's just a matter of time. The only question is "when?"
Some will argue that it's too expensive, that we should wait until we have better technology. But how will we get that technology in the first place? It doesn't just fall into your lap one afternoon; you have to work for it. Imagine if we'd decided 100 years ago that trying to develop airplanes was stupid, that airplanes at the time were too dangerous and impractical, and that we should wait until we had technology like the 777 oir A380... I'll tell you right now, we probably wouldn't be to that point for a couple hundred more years. You don't learn how to build entirely new stuff or do new things by sitting around dreaming about it or making powerpoint charts... you learn by doing that stuff as best you can, learning from your mistakes, and doing it again. Lather, rinse, repeat.
Yes, doing it is expensive. But it's worth it. The only reason it seems like it's not is that the payoff takes a little longer to come. Corporations don't undertake it because the shareholders probably won't see the benefit within their lifetimes. Governments don't do it because they don't think beyond the next election. Joe Public doesn't think about it because his attention span lasts for 20 seconds and all he's interested in is what keeps him entertained.

I think that's the case.
It really boils down to two things; a) engineering conservatism - what we've done so fat mostly works and nobody really raises a stink, and b) the extremely low total number of design generation

Link to the wayback machine for spacex's website in 2004ish http://web.archive.org/web/20040520043224/http://spacex.com/ [archive.org] If you compare that with the actual launch dates on the current version of the website, you will see that their time line did slip by about 2 years along the way. So Mr. Negative does have some ground to stand on.
On the other hand, 2 years slippage of the schedule does no

I've never claimed it does - merely pointed out that the optimism of many space 'fans' is unsupported by the record to date.

NASA has even been criticized for not capitalizing on commercial space launch opportunities as Russia and China have done. I, however, applaud them for staying out of the way. NASA's goal is "to pioneer the future in space exploration, scientific discovery, and aeronautics research." No part of that statement involves commercial interests.
You should check out the 1958 charter which created NASA:

Sec. 203. (a) The Administration [NASA], in order to carry out the purpose of this Act, shall-- ...

Just to clarify, if you RTFA you will find that SpaceX has completed all the milestones so far on time, and they are looking at a 2-4 month schedule slip on future milestones. Now, obviously we'd much rather not have the schedule slip, but in the world of NASA contracting that is like... totally nothing. I have to say that, as a confirmed space nut, SpaceX really impresses me.
It's also worth comparing to something like NASA's Ares I launcher, which has projected costs upwards of $40 billion and just recently announced a schedule slip of 18 months; many are doubtful that even limitless funding and time would enable it to work around its fundamental design faults.
By comparison, the entire COTS program (both SpaceX and Orbital combined) has a total budget of less than $500 million (yes, almost 100x less than the Ares I despite having similar capabilities). Having a schedule slip of

They don't have the limitless budget that NASA had during the cold war, and it isn't about waving dicks at each other either - its about building re-usable vehicles that are commercially viable (for some of the companies anyway).

The article subject line is misleading. One thing is certain, the commercial space business will not go back to where it came from, the blossoming has passed the point of no return. Given time, it will get off the ground. Given time, pigs will fly too, and birds will breathe nitrogen.

It's rare to see people in business with a passion for doing something -- something other than making obscene piles of cash, that is. In this environment, it's all about the fast buck and fuck the rest.

Yes, new.space can succeed. It will require more than just NASA's cash to happen. It will require new payloads and new businesses to utilize these launchers.
Commercial/semi-commercial launchers such as Ariane, Proton, Delta, Atlas, Zenit, Pegasus etc have been flying commercial communications and imaging satellites for decades. The question is whether new types of businesses can emerge to create new markets for more launches.
