“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.

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.

X-37B Returns Successfully

It baffles me why we need capsules when the Air Force and Boeing can do this.

Pad Abort Test Launch Video Compilation

Still no public pics of the LAS “lawn dart”, but there’s lots of fun eye candy in this video, especially the beautiful slow-motion footage at the beginning of the motor ignition:

A few interesting things to note:

  • The impressively crisp black and white footage of the reorientation and jettison
  • The docking-hatch-view of the forward bay cover jettison and chute deployment
  • The amusing (but very brief) cameo appearance of the jettisoned LAS in the background of one of the chute deployment cuts, weathervaning into a point-down attitude
  • The firing of the attitude control motor, which appears as eight skinny flames near the tip of the LAS stack
  • The fact that there is NO visible plume damage on the capsule or the LAS adapter cone (especially surprising given the incinerated appearance of the cone after impact with the desert floor)

PA-1 Test – A Little TOO Successful?

A little bit behind schedule (it was supposed to launch before the 2008 Presidential election), the Pad Abort 1 test launched at White Sands yesterday — and would have subjected any astronauts inside to 16 gees. Oops.

The one-minute, 35-second test at White Sands Missile Range, N.M., took the capsule higher — 3,886 feet — and farther down range — 6,919 feet — than anticipated.

“That motor was quite a performer,” said Deputy Test Director Jay Estes. “You might not want to be riding in there.”

That’s the truth in more ways than he intended, I’m sure. (And I can’t be the only one who finds it amusing that one of the guys launching a big solid rocket is named “Estes”.)

Were the program to be continued, this excess capability might actually be a good thing to have, given how much the capsule has changed since the PA-1 design was frozen (more to the point: how much more it weighs now).

Landing was gentler than expected, but a heavier capsule would work against that:

The boilerplate capsule floated down to the desert floor under the three red-and-white main chutes, slowed enough by them that the telemetry system continued to operate after impact. Estes said test engineers received all of the data they expected to receive.

“It was a beautiful flight,” he said. “That went like clockwork from what I could see.”

Don Reed, the NASA test director, said the capsule touched down at about 24 feet per second (fps), less than the 33 fps impact velocity predicted at the outset. That sort of data will be helpful as NASA refines its predictive models for future developments.

The best part of the test, though, was that the discarded motor stack turned into an enormous lawn dart. I don’t have permission to share the pics that were floating around the office today, but the shots of the burning adapter cone sticking up out of the desert floor are awesome — since the entire 40-odd-foot-tall tower above it is buried nearly vertically into the ground, along with about 40% of the cone itself, with just a small bulge of dirt humped up around it. It’s such a perfect needle-jab that it’s ridiculous. As for the rest of the hardware, the early reports suggested that, given another LAS, the boilerplate capsule and even the separately-jettisoned forward bay (parachute) cover could have been launched again in short order.

For Whatever It’s Worth…

PA-1 is scheduled to launch at 9am EDT  Thursday May 6.

Orion launch abort  vehicle

NASA’s Pad Abort 1 will be the first fully integrated flight test of the launch abort system being developed for the Orion crew vehicle. The test is part of an ongoing mission to develop safer vehicles for human spaceflight applications.

Hmm…then again, maybe it won’t be.

Came across this display in the outer lobby on my way out of the office this evening – apparently, another attempt by the earnest young engineers squad to gather petition signatures in favor of preserving the program of record.

UPDATE: So, Thursday there were a couple of the aforementioned earnest young engineers staffing the table (presumably on their own time). The purpose of this signature drive was not, as it turns out, to encourage Colorado’s Congressional delegation to preserve the program of record, but to thank them for having “saved Orion”.

Which makes me wonder if there was a table like this at South Park West, where the LAS and service module teams are located…
