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)

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.

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

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.

If James Cameron is so passionate about restoring the 3D camera to MSL/Curiosity, then…instead of lobbying, and urging, and taking his concerns to the NASA administrator, why didn’t he just pay for it out of pocket?

I don’t know that he didn’t, or didn’t offer to do so (the article doesn’t say), but it seems like the obvious thing to do for a guy with a passion and a couple billion dollars in the bank. Indeed, a sponsorship arrangement with NASA would have been a coup for both. Trade Cameron the rights to market the resulting imagery in exchange for underwriting the camera, let him produce a theatrical 3D documentary using it, and both win: Cameron cleans up at the box office, and NASA gets a great PR and education/information outreach opportunity.

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…

This has been out for a while now – don’t know how I missed it. “That’s trouble of some kind, George!”

Finally got the time to upload the longer version of the video of Monday’s launch.

Okay, not really. But they are giving it the ability to autonomously select science targets based on general guidelines:

The new system, which NASA uploaded over the past few months, is called Autonomous Exploration for Gathering Increased Science, or AEGIS and it lets Opportunity’s computer examine images that the rover takes with its wide-angle navigation camera after a drive, and recognize rocks that meet specified criteria, such as rounded shape or light color. It can then center its narrower-angle panoramic camera on the chosen target and take multiple images through color filters, NASA stated. 

AEGIS lets Opportunity look at rocks at stopping points along a single day’s drive or at the end of the day’s drive. This lets it identify and examine targets of interest that might otherwise be missed, NASA said. 

NASA said the first images taken by the Mars rover choosing its own target show a rock about the size of a football, tan in color and layered in texture. It appears to be one of the rocks tossed outward onto the surface when an impact dug a nearby crater. Opportunity pointed its panoramic camera at this unnamed rock after analyzing a wider-angle photo taken by the rover’s navigation camera at the end of a drive on March 4. Opportunity decided that this particular rock, out of more than 50 in the navigation camera photo, best met the criteria that researchers had set for a target of interest: large and dark, NASA stated. 

Cool. But while it increases the productivity of this and future rovers, it isn’t going to eliminate the utility of sending humans to explore – or their essential role in settlement which, by definition, is not something robots have the ability to do.

I’m curious as to where the developers at NASA plan to take this technology in the future. Will evolved versions allow for (for instance) faster-moving rovers capable of covering more ground instead of waiting for detailed instructions? How much serendipity or “curiosity” will be allowed in the programming – that is, how broad will the selection criteria be, how much autonomy will future rovers have to pursue their own selections, and will the process be recursive, allowing the rover to reevaluate and select new science targets based on unexpected discoveries at a previously-selected target? Imagine a fleet of small, fast, simple, mass-produced rovers with loose guidlines and broad autonomy, scattered over the surface of Mars and allowed to wander at will, subject to occasional nudges from controllers back on Earth towards features of interest.

I’m at Michoud this week on business, and had the opportunity to visit the factory today for the first time in nearly a year.

What a change ten months can make.

While last year, the dome tooling was still mostly in place (a few of the mechanical assembly pedestals had been pulled up), most of the mechanical assembly area and associated material cribs have been cleared out, leaving behind only the more complicated tools used for NC machining of the SRB fittings. Last year, there was still a pair of LOx tanks in post-proof inspection near the end of the production line, and an LH2 tank which had just had its forward dome (the last major segment) welded on. Today, all of the weld tools (domes, barrels, ogives, and major weld) had been mothballed and wrapped up, along with the large milling machines and lathes used to trim the various segments – it was like walking through a winter storage facility filled with shrink-wrapped boats.

What impressed me the most, however, was that for the first time in twelve-plus years, I saw areas of the factory with the lights turned off.

What this suggests is that there isn’t any hardware work going on to extend the Shuttle program beyond the number of tanks currently on-hand or in final assembly. If, as rumored, NASA is directed to extend the Shuttle program, they’d better start soon if they don’t want to end up with the long gap such an extension would be meant to avoid or minimize – due simply to the time lag in tank manufacturing.  And if what I was told about spares is true, it may only be possible to manufacture two additional tanks, assuming at that that everything would go perfectly and none of the spare components on order or in house have unrepairable defects or damage. With the one flightworthy tank I’m told will be left over at the end of the Shuttle program, that means an extension of at most three flights before the supply chain would need to be restarted — at considerable expense and delay.
