Saturn V Resurrection

Sorta… Lee Hutchison at Ars Technica has two new articles on efforts to resurrect and/or evolve the F-1 engine:

New F-1B rocket engine upgrades Apollo-era design with 1.8M lbs of thrust

How NASA brought the monstrous F-1 “moon rocket” engine back to life

The former details the efforts by Pratt & Whitney and Dynetics to evolve the F-1/F-1A designs into the F-1B: a new engine derived from the old, using modern manufacturing methods and control systems where beneficial. It’s especially interesting because I’ve long thought calls by laypeople and Congressmen and the like to bring the Saturn V into production would (if heeded) lead to exactly this…by the time you take advantage of the cost-saving technological improvements (and the loss of certain outmoded manufacturing capabilities) since 1960, you may end up with a machine that looks and performs much as the original, but shares only a partial pedigree with it. The temptation/opportunity to make it better is too great, and one would be foolish not to do so. Efforts on the F-1B are an impressive example of this.

The latter is an example of something I think we need a lot more of: hands-on experience for younger engineers. Building something new or reverse-engineering something old, doesn’t matter, it’s a great opportunity for learning that simply making CAD models and PowerPoints of “paper rockets” will never get you.

And check out those welds – wow.

Backyard Spaceship

I could see me doing something like this: Dad Builds Homemade Spaceship For Son in Backyard

What? For the kids? Forget the kids – I’d do this for me! I’m still amused that while working on Orion I got to play in personally inspect Apollo 17′s CM, a Soyuz trainer, and two different Orion CM mockups.

“Iron Sky” – the First Four Minutes

An amusing sneak preview of the upcoming Nazis-on-the-Moon movie Iron Sky:

It’s partly amusing because they use a pretty good replica of an Orion as the “Liberty” spacecraft, and partly because they appear to be leavening the lampooning of Sarah Palin with some mockery of Obama. That suggests to me that said lampooning is done in fun and not malice, like a Hollywood film would handle it.

And yes…the space Nazis have an Autobahn on the Moon.

I hope this movie ends up being as fun as it looks, but then Dead Snow (with zombie Nazis, as it happens) looked this good in trailers and previews, too.

Something Missing?

Nice picture hereof the first weld on The Vehicle Presently Known As OFT-1.

Note the matte black paint around the windows, a detail we didn’t see on GTA. The panel in view is from sector F, so the hidden panel on the other side would be its (essentially) mirror-image A, making this the weld at the 12:00 position (between the windows). [Correction: no, the welded-to piece is a cone longeron, not the sector-A panel. Derp.] The further away of the two windows is canted inboard to provide forward views for rendezvous and docking.

One curious but annoying (yet common) omission here is any mention that the work isn’t being performed by NASA but by Lockheed Martin. Unless you knew, you would be given the impression by the language here that it was otherwise – “Engineers at NASA’s Michoud Assembly Facility” being factually correct but completely misleading. We saw the same thing after Katrina, when NASA issued a press release thanking the rideout crew who saved MAF from flooding, never mentioning LM (the facility operator at the time and employer of most of the crew) and carefully phrasing things to imply – without stating it explicitly – that they were all NASA civil servants.

Why do they do that? Strange.

Blue Origin Gains Some Useful Experience

…by crashing a test vehicle – Successful Short Hop, Set Back, and Next Vehicle:

Three months ago, we successfully flew our second test vehicle in a short hop mission, and then last week we lost the vehicle during a developmental test at Mach 1.2 and an altitude of 45,000 feet. A flight instability drove an angle of attack that triggered our range safety system to terminate thrust on the vehicle. Not the outcome any of us wanted, but we’re signed up for this to be hard, and the Blue Origin team is doing an outstanding job. We’re already working on our next development vehicle.

Nobody wants to lose a test vehicle, of course, but this can actually be a useful development — as anyone who has read Henry Petroski’s books understands, you learn more from your failures than from your successes. It has always struck me as the wrong approach that Orion didn’t budget and schedule a bunch of simple test vehicles, with potential failures and learning from them in mind. Yes there are test vehicles, but they’re each quite complex and expensive, and the failure of any one of them will be seen as a major black eye to the whole program (regardless of what might be learned).

Fortunately, given Bezos’ ability to fund the project, NASA getting cold feet over COTS or CCDEV after a failure probably isn’t much of a threat to the ongoing efforts he mentions in the post.

Must Be Nice…

Boeing is already recruiting employees for their first crewed CST-100 flight.

Orion has a crewed version planned for…um…”eventually”. That’s got to count for something…right?

Final Shuttle Flight Thoughts

I’ve been offline for most of the past week with DSL issues, so didn’t get to see any of the coverage of the final Shuttle launch until this afternoon. Haven’t yet found the ET “death camera” footage (though someone at a wedding I attended yesterday mentioned having seen it), but here’s the normal launch-through-sep version from Friday’s launch.

I did, however, catch a bit of commentary on the radio while running errands Friday afternoon. Not sure what show it was (didn’t recognize the host — name was something like “Joe Pax”), but I tuned in just in time to hear a rant about how the end of the Shuttle program without a replacement on hand was a national tragedy, and that it came about because Obama cancelled Bush’s space policy only because it was Bush’s space policy.

Let’s unpack that, shall we?

The “national tragedy” bit simply repeated the received (un)wisdom that the end of Shuttle = end of US manned space exploration. Not so — NASA civil servant astronauts will still be flying to the predominantly-US International Space Station for the foreseeable future, albeit via the Russian Soyuz. New domestically-built and -launched spacecraft are a couple years out, so yes, we won’t be able to send NASA astronauts up on American-made vehicles for a while, but that does not equate to the end of an American presence in space. This part, though, I can understand — if someone hasn’t been following post-Columbia space policy, it may seem as though we are simply shutting down the manned side of NASA and giving up on space.

The worse flaw in his argument is the assertion (very strongly and unambiguously made by the host) that Obama cancelled the policy because it was Bush’s. This is utter bullshit, which a few minutes of research would have revealed as such. The policy that Obama cancelled (in part) was Mike Griffin’s, not George W. Bush’s. (While it’s true that Griffin reported to Bush who was in turn ultimately responsible, Constellation was unquestionably Griffin’s ill-begotten baby.) Bush gave us the broad policy of the VSE, which was later hijacked at the implementation level by Mike Griffin for his own vanity projects — the crowning glory of which was his Ares I launcher.

Griffin’s Constellation architecture is what was largely cancelled in February 2010, and with good reason — it was ill-conceived, over-sold, over-budget, under-performing, and behind schedule (more on that last in a moment). Obama’s cancellation of Griffin’s program was arguably the only good thing the man has accomplished as President, and it was done not out of spite for his predecessor (which I admittedly wouldn’t put beyond him), but because of the aforementioned problems.

And this brings us to the “gap” in American manned access to space, which was the inspiration for the rant. Had it not been for Griffin’s Ares-based Constellation architecture and its follow-on effects on the design of Orion, Orion might well have been ready to fly by now, or at the least with a minimal “gap” between Shuttle flyout and Orion IOC. Constant redesigns of Ares I and trouble meeting its performance goals meant redesigns and ultimately the stripping down of Orion, which in turn led to schedule slips with the latter. Had Orion (whether in in the original lifting-body form or the Griffin-mandated capsule form) been directed to fly on an EELV — in-production rockets with known performance characteristics and much more benign flight environments — a good portion of its development schedule slip could have been avoided. Which means we would have had little if any “gap” to cause radio talk show hosts consternation, nor reason for said hosts to suspect partisan motivations behind a necessary shift in space policy.

To be fair, when I came back to the program about fifteen minutes later, the host was admitting (apparently at the prompting of a caller I had missed in the meantime) that the shift to a more commercial orientation for manned access to space was a welcome development. But rather than rethink his earlier foolishness, he stuck to his guns and (incredibly, for a supposedly right-wing, pro-business, free-markets type of host) expressed doubt that commercial providers could ever fill that role. Which is disappointing — if people who are supposed to favor private enterprise allow their “national greatness” emotional priorities take precedence over letting a new industry take root, who will defend the new industry against those who don’t favor private enterprise?

Orion Program History?

It occurred to me (again) the other day that the history of the Orion program to-date is a rich mine of project management lessons. Unfortunately, I don’t know that anyone on the inside has been keeping a detailed history of the program along the way.

I wish it had occurred to me to do so six years ago. The lower-level issues and decisions I’ve been involved in would alone make for some very interesting case studies.

De-cancellated

So, it looks like The Vehicle Formerly/Formally Known As Orion has a new lease on life. For now.

NASA has reached an important milestone for the next U.S. transportation system that will carry humans into deep space. NASA Administrator Charles Bolden announced today that the system will be based on designs originally planned for the Orion Crew Exploration Vehicle. Those plans now will be used to develop a new spacecraft known as the Multi-Purpose Crew Vehicle (MPCV).

Peachy. Have we gone through enough iterations that we can start calling the new vehicle “Fred“?

This isn’t anything new, as this idea in general form has been floating around since shortly after the “cancellation” announcement in February 2010. What’s concerning, however, is the notion that the MPCV would be able to support crews of 4 for 21 days, all on its own. On Orion, that longevity had been been moved to a post-ISS-version block upgrade. If that becomes the baseline for the initial operational capability of the MPCV, it’s back to the drawing boards, at least for ECLSS.

The Free Frontier

Bill Whittle and Rand Simberg have an interesting video out on the “new space age” — you know, the one that started on July 21, 2004…

I’d quibble with a few of Whittle’s comments that relate to Orion, but other than that, it’s worth watching. It’s almost enough to make me run out and join a startup right now
