It’s The End Of the World As We Know It

Well, you would have thought so from some of the nailbiting hall talk and email at work today concerning the announcement that the Obama administration will push for the cancellation of Constellation, replacing it with initiatives aimed at bringing the nascent commercial spaceflight industry into bloom. The doom and gloom around Orion was in (understandable) contrast to the delight (or simple satisfaction) seen around the space blogosphere.

I think Michael Mealing comes closest to my own attitude towards this development:

President Obama’s new policy for NASA is the most fiscally conservative and downright capitalist policy to come along since the agency was founded. 

And yes, it really boggles my mind that that should be the case. Obama? Capitalist? Who’da thunk? As one co-worker quipped today, Obama seems confused: he wants to nationalize a private industry in healthcare, but privatize the national program in manned space. One thing that has really surprised me today is how many of my friends have called or emailed me, expressing shock and disappointment that we are now “abandoning” space – unwittingly accepting the premise that a government program is our only possible means of getting people there. The perception that government is the sole entity capable of conducting manned spaceflight is so ingrained and unquestioned that it doesn’t seem to occur to even those who claim to be capitalists to question it.

But of course, I have to temper my surprise and excitement at this prospect, much as I did regarding the newfound enthusiasm for nuclear power Mr. Obama expressed in his SOTU last week. There’s going to be a lot of haggling to get the Congressional NASA caucus on board with this (although one Senator who could have been expected to be among the biggest roadblocks seems to be climbing on board – however reluctantly). It’s going to take some time, and who knows, just as ESAS made a dog’s breakfast of the VSE, so too could Congressional compromises and NASA resistance turn the promise of this new policy direction into yet another dead end.

Christmas Comes Early, Part II (Maybe)

Although Keith warns that the story is premature and may not be correct in its particulars, this Science Insider preview of the Obama administration’s revised space policy (particularly regarding Constellation) indicates that it might include some longed-for Christmas presents…including (and especially) the cancellation of Ares I.

I can’t say that I’m thrilled at the possibility of handing off Altair and the hypothetical lunar base to international partners, given the distortions that imposed on the ISS (e.g.: the higher-inclination orbit that allowed Soyuz to reach ISS from Kazakhstan). Nor am I especially enthusiastic about the possibility of accelerating the development of the unneeded Ares V, but I do recognize that it would be a political necessity to appease Sen. Shelby (R-Huntsville Makework Jobs) should Ares I actually get the long-overdue and well-deserved axe. Nor am I thrilled that NASA may be given $1-4B more, given the waste that has already plagued Constellation (Ares-1X, MLAS, and Ares I design mitigations, for example).

The potential stocking stuffers in this story, though, are the appearance that commercial cargo to ISS is finally being taken seriously as a part of NASA’s operations, and (personally, since I work on Orion) the possibility that Orion could switch to riding an EELV as it should have from the beginning. If true, the former will be a big boost to a true commercial space transportation industry, and the latter will make our design job on Orion a heck of a lot easier through more benign launch and abort environments and mass margins (not to mention the stack won’t look like a corndog any more — that’s just embarrassing).  While the rumored policy update does nothing to address what I consider to be the root problem — NASA shouldn’t be doing this stuff in the first place, but rather (if anything at all) encouraging through tech transfer and incentives the growth of robust private sector space industries — it would at least be a step towards a somewhat more sensible way of doing what the agency has been tasked with doing.

ESAS Appendices Made Public

By NASASpaceFlight.com. At their subscription site.

Jon Goff has a few interesting details from his first look at the appendices:

Now, having seen some of what’s in them (I’ve mostly been focusing on the 300+ page appendix to Chapter 6, that details all of their launch vehicle related decisions), I can understand why some people might not want that data to see the light of day. I was hoping to get permission to post a screenshot or two and some direct quotes, but for now you’ll have to get a subscription and check it out yourself.

Some gems to look for when you get a chance, all within the first 40 pages:

  • Exceptions given in the ground rules and assumptions on maximum dynamic pressures to In-line SRM based crew launch concepts that weren’t given to any other vehicles (without the exception, all of the five-segment Stick concepts would’ve been ruled out from the start).
  • Unrealistically assuming a fixed LAS mass regardless of first stage characteristics (like T/W, max-Q, and whether you can shut them down or not).
  • Inaccurate dry mass numbers for existing EELV upper stages (just as some of the guys on NASASpaceflight.com had been saying for years now).

Hmm… It’s almost as if the study was rigged to generate a particular outcome…

I can’t wait to see what other “gems” are buried in the full text. Of course, I will wait, since I’m not going to pay for a “level 2″ subscription at NSF to obtain copies of information that I’ve already paid for (that, and I’m not going to help support a site which I loathe for its constantly-flickering animated ads).
