ATK to get unfunded CCDev agreement?

Last Friday NASA announced that the space agency and ATK would announce an agreement this Tuesday “that could accelerate the availability of U.S. commercial crew transportation capabilities”. (The announcement was originally going to be only available to media calling into a telecon line, but NASA said Monday the announcement will be on NASA TV at 3 pm EDT.) The announcement has generated various degrees of glee or despair, depending on one’s opinions about ATK’s work on solid rocket motors it has proposed for its Liberty rocket and is seeking to have incorporated into NASA’s Space Launch System (SLS) heavy-lift rocket.

What seems likely to be announced tomorrow, though, is some kind of unfunded Space Act Agreement that is part of NASA’s second-round Commercial Crew Development (CCDev) program. NASA already has one such unfunded CCDev-2 agreement, with United Launch Alliance (ULA); when that agreement was announced in July, NASA administrator Charles Bolden said that it “may speed the development of a commercial crew transportation system for the International Space Station”, language similar to the announcement last week. Given that the funded CCDev-2 awards focused on spacecraft development, unfunded agreements allow companies like ULA and ATK to keep their launch vehicle efforts on track, although they get no funding from NASA.

The announcement comes just after ATK performed the third successful test-firing of its five-segment solid rocket motor, originally intended for the Ares 1 and Ares 5 but now proposed for Liberty and SLS. An unfunded CCDev-2 award would help ATK keep the Liberty vehicle on track. There’s one problem, though: right now there’s no obvious commercial crew customer for Liberty. Of the four funded CCDev-2 vehicle developers, three (Blue Origin, Sierra Nevada, and, most recently, Boeing) have selected ULA’s Atlas 5, while SpaceX, not surprisingly, is sticking with its own Falcon 9 rocket. Unless another company enters the commercial crew competition down the road, or one of ULA’s customers have second thoughts, Liberty may remain on the outside looking in.

Keeping Rocket Engine Fuel Lines Bubble Free in Space

You are in space...your spacecraft is tumbling out of control, you need to fire your control rockets, the fuel is sloshing all around the inside of the tank...where is your liquid fuel? Without gravity in the space environment, how do you keep the fuel contained so it can be transported to where it is needed? How do you keep gas bubbles out of the fuel lines?
Being able to use all of the fuel in a spacecraft tank has been an ongoing challenge in spacecraft design for the past 50 years, but great advances on the problem are being made using the International Space Station as a laboratory. In the microgravity of space, the "bottom" of the tank is NOT apparent.
When a spacecraft tank is nearly full, the fuel tends to "cling" to all sides of the tank leaving a small gas bubble, or ullage, near the center of the tank. Once the tank has emptied to the point where there is not enough liquid to cover the walls of the tank, it is not clear where the remaining fluid is "positioned." Here on Earth this is not an issue. For example, in the gasoline tank in your car, gravity always positions the remaining fluid at the bottom of the tank, allowing the car's fuel pump to draw the last bit of fuel from the tank.
"Presently, the low risk solution to this problem is to size the fuel tank larger than what is needed for the mission, but this adds extra launch mass and volume to the spacecraft," states Robert Green at NASA's Glenn Research Center. Another method is to add special channel-like structures, called vanes, inside the tank to purposely "wick" the remaining fuel to the exit. A key area of study is how different shapes of channels work and whether they remove any gas bubbles that can get captured in the flow.
Scientists from Germany and the U.S. have been studying these processes as part of an investigation called Capillary Channel Flow, or CCF. The CCF study looks at several capillary channel geometries that mimic the shape and physical characteristics of vanes in fuel tanks.
One set of capillary channel geometries was developed by Michael E. Dreyer at the Center of Applied Space Technology and Microgravity, or ZARM, at the University of Bremen in Bremen, Germany, and sponsored by the German Aerospace Center, or DLR. The geometries included parallel plates and square-grooves. This part of the investigation was completed in March 2011, after 78 days of nearly continuous ground-controlled operation.
The second set of channel geometries was designed by Mark M. Weislogel at Portland State University in Portland, Ore. Sponsored by NASA, it will begin operation this month. The geometry is a wedge-shaped channel with only one side exposed to the interior of the tank. Weislogel is studying the fluid behavior in the interior corner where the two plates meet. This area forms a wedge-shaped channel geometry, which forces gas bubbles to rise and burst past the liquid surface. This new shape enables the passive separation of gas from liquid.
Every space system that includes a fluid, from drinking water, to radiators, to toilets, can have problems with transport and bubbles. So using the geometry of the channel to remove bubbles can be a real advantage, as Weislogel explained when discussing the importance of studying the wedge shape. "In a spacecraft tank application, if gas bubbles get to the engine, the engine can sputter or stall. If the fuel lines have these wedge-shaped sections, they can expel the gas en route, and the wedge-shaped section takes care of the separation for you," said Weislogel.
The CCF investigation was installed in the Microgravity Science Glovebox, or MSG, a research facility aboard the space station. The MSG facility is designed to accommodate small science and technology experiments in a workbench type environment. The experiment can be controlled from NASA's Glenn Research Center, from Germany, or at Portland State.
"Technologies utilizing capillary flow can be used in applications on Earth," explained Green. "CCF results may potentially be applied for improving fluid flow in miniaturized biological devices used for health screening and analysis -- referred to as lab-on-a-chip."

X2.1 Solar Flare and CME

Sunspot 1283 erupted with another flare yesterday that peaked at 6:20 PM ET. This was an X2.1 class flare, some four times stronger than the earlier flare. Flares can affect Earth's ionosphere, through which high frequency radio waves travel, and cause radio blackouts. This strength flare can cause a "strong" radio blackout, categorized as R3, which has the potential to cause about an hour-long blackout.
This flare, too, had a coronal mass ejection (CME) – an eruption of a giant cloud of solar material -- associated with it. Early models suggest that both CMEs will not travel directly toward Earth, but perhaps just graze our atmosphere in the North, potentially causing auroras in the northern latitudes.
Further updates on the event will be provided as they become available.

Exploring the potential for alternative worlds at Burning Man

I recently returned to Toronto from my first Burning Man experience and I have to say that the trip was as close to science fiction as it gets. It was a world of alien landscapes, extreme conditions, bizarre modes of transport, and a local population right out of Tatooine's Mos Eisely spaceport. Add to that a dash of Mad Max, Dune and Woodstock, throw in some glow sticks, flamethrowers, and shiny metallic pants, and you get the picture.

More interesting than that, however, was how otherworldly the place felt from a civilizational perspective. For the week that I was at Black Rock City I truly felt like a stranger in a strange land, a foreign visitor to a place far removed from my home-world. Indeed, it didn't take long for the cogs in my brain to start churning away in reaction to all that I was witnessing. Burning Man is a fascinating event on so many levels, including its sudden emergence from the dust and the rise of an alternative society that exists in virtual isolation from the real world—albeit one that lasts for just a week each year.

Welcome to Black Rock City

Okay, for those who have been hopelessly stuck in a dark hole for the past ten years, Burning Man is an annual counter-cultural festival that takes place in the Black Rock Desert of Nevada. Yes, that's right—right smack dab in the middle of nowhere. For some twisted and seemingly inexplicable reason, over 55,000 people from around the world arrive at this place and, quite literally, construct a thriving city from scratch, only to tear and burn it all down a week later.

Once Burning Man gets underway, Black Rock City rises from the desert in the form of a semi-circular patchwork of tents, yurts, RVs, trailers, vans, kitchen sinks and anything else that can be cobbled together to create temporary living conditions in what is truly an unrelenting desert environment. The days are excruciatingly hot, the nights unbearably cold—and it's all frequented by regular sand storms just to rub it all in.

The festival itself is an intense celebration of sights and sounds in which participants, called Burners, create what is without a doubt the largest party in the world (try to name another party you can see from space!). Everything that happens in the city is a product of un-cordinated individual efforts; aside from a few things (such as the Temple and Center Camp) it's a completely self-generated event. For a brief one week period, Black Rock City erupts into a spectacular showcase of art displays, elaborate costumes, performance art, dancing, live music, and much, much more (including the racy stuff that happens behind the scenes). The event serves as a platform for Burning Man's central tenant: radical self-expression. The possibilities are nearly endless given such an open precept.

As a first time Burner, I quickly learned that no images or words could prepare me for the spectacle that is Burning Man. You truly have to experience it yourself to appreciate the scale, context and brilliance of it all. And this includes the organizational and social aspects as well. Black Rock City is a truly remarkable place when viewed through sociological, cultural and anthropological lenses. During my short time there I quickly came up with a hand-full of potential studies that could easily fuel PhD theses. It's truly a mind-expanding social experiment that's worthy of academic inquiry.


Emergent and spontaneous order

Burning Man is something every futurist and transhumanist should be aware of. Black Rock City is a model that could serve for the development of entirely novel alternative communities and societies. Indeed, the Burner term for the real world is "default society," and after a few days at Burning Man one can't help but gain a growing appreciation for what that actually means.

 Take the sheer numbers for example. Over 55,000 people are packed into an area no more than five square miles (roughly the size of downtown San Francisco). While this is a moderately impressive feat at best, it's the civility and functionality of the community that is impressive. Despite the fact that many of Black Rock City's inhabitants are simply there to party, the place remains remarkably well maintained and orderly over the course of the week. I would dare say that it's probably the safest city of 55,000 people in the world while it lasts.

A central credo of Burning Man is that each Burner is responsible for taking away what they brought in and to "leave no trace." Consequently, there are absolutely no trash cans in the city. Waste is a personal responsibility (except for bio-waste—the organizers provide porta-potties). Moreover, should any trash hit the playa (a term for the desert floor), it is immediately identified as MOOP (matter out of place) and dealt with. What's even more astounding is that, in the event that some garbage gets away, there are Burners who, completely unasked, pick it up themselves and deal with it. I met one woman who over the course of one night picked up over 65 cigarette butts without anyone asking her. A friend devised an internal rule in which she picked up an extra piece off MOOP for every piece of her own she dropped. It goes to show that, given a strong enough cultural imperative to keep the place clean, there will be enough people out of the 55,000 who will, of their own volition, deal with it themselves. Call it an emergent effect of having a strong culturally bound population.


The gifting method

Which brings to mind another indelible aspect of Burning Man: it runs on a gift economy. Money is absolutely no good at Burning Man (except at Center Camp where Burners can purchase ice and coffee—pretty funny if you think about it; talk about your basic needs). This doesn't imply a barter economy. There is no trading at Burning Man. People simply "gift" things to people whenever it is needed. Sure, given that it's in the middle of the desert and that there's only so much you can bring in and give away, this practice is fairly limited, but I was astounded at what was being offered in the city: ice cream, freezies, snow cones, alcoholic drinks of all sorts (I even had some Patron tequila at Barbie Death Camp — but that's another story), hair washing, butt cleaning station (again, you'd have to be there to understand this), and even an inter-city post office, FM radio station, and dating service. And plenty more. Basically, if there was a need for it, someone pretty much prepared for it.

 I also took part in this gift economy. As a member of FutureCamp I gave three presentations as part of my contribution to the larger community.

Gifting, it would seem, can include goods, services, and even the sharing of ideas and expertise.

It would seem that, in a land of extreme scarcity, and where gifting is the only means of exchange, people naturally fill in the gaps. And to say that there is nothing given in exchange for contributions is not entirely fair; human interaction (which is high value at Burning Man) and the satisfaction of helping others is certainly part of the equation. The desolation and harsh environment, along with the extreme scarcity of food, goods, and other creature comforts, is a strangely indelible component of Burning Man. It adds to the alien and otherworldly sense, but it also binds the community together, both in terms of shared hardship and in the increased need to look out for one another.


Maintaining order

One of the neat aesthetics of Burning Man is the seemingly invisible or complete absence of authority. Yes, there are Nevada state troopers patrolling the city, but they're largely ignored in much the same way that money is (annoying props to remind Burners that the outside world still exists). Burning Man does have a force of Rangers—a group of volunteers who walk around the city providing help and guidance when needed. But they have absolutely no authority. In fact, they won't even offer an admonition if they see a Burner doing something potentially dangerous. But they'll stick around in case help is eventually required.

Indeed, excruciatingly simple rules, norms, and an implicit code of conduct seem to be all that's required to keep it all together. Perhaps it's the limited population, short timeframe, and harsh conditions that allows for this. Or maybe it's the strict zoning rules that are put into place (bad apples don't get to come back). Burners may also comprise a highly filtered group, the demographic nature of which needs to be better determined. These are certainly important variables to consider, including the overarching question as to how far the model can be extended before a kind of critical mass is reached and it all starts to fall apart.

In fact, it does start to fall apart, but not until the last day. Once the Black Rock exodus begins, sign-posts are torn down and the civility that had previously characterized the place all but disappears. It would seem that, among the variables required for long-term sustainability, a finite timeframe is required. I strongly believe that given its current parameters (dwindling food and water supplies notwithstanding) Black Rock City could successfully function for weeks—if not months—but that a specific length of time needs to be clearly defined.

 The question of sustainability

The topic of sustainability is a concern to many Burners. The question as to how long a community like this can be maintained is a pertinent one, particularly when you find yourself in it. A central sentiment that runs through the culture is that it can't really be sustained and the best that one can do is "bring a bit of Burning Man to the default world."

I've got a different take on the matter. As a futurist who foresees such things as the end of scarcity and the complete automation of production, the idea that we can actually create a viable and permanent vacation world is an intriguing one.

As it stands, Burning Man can't exist without the resources that are provided by the Burners themselves. Consequently, it's a leech economy. Black Rock City has virtually no real economy of its own in terms of local production. Everything that exists in Black Rock City comes from the default world, whether it be material goods or even individual skills and talents. The default world, and the efforts of Burners while they're there, is the engine that drives Burning Man. The trick, therefore, is to decrease the real-world burden on the Burners themselves—and that's where disruptive technologies like robotics and fabs (desktop molecular assemblers) come in.

Alternative societies—those communities that have essentially no internal production economy and exist in relative isolation from the mainstream world—can only exist across expanded time domains as the time required for its inhabitants to work in the default society decreases.

Advanced technologies that will result in such things as increased automation will serve to enable this. Eventually, an alternative society like Burning Man could exist in perpetuity so long as the means of production in the default world comes at a zero cost. In other words, the inhabitants of alternative worlds will finally be able to stay there only once the real world can sustain it without burden.


Looking forward

There's a lot more to Burning Man than I've let on here. I've completely ignored some socio-cultural issues that I'll expand upon in a subsequent post. But let it be said that Burning Man is an absolute treasure that's worth preserving, if not expanding upon altogether. Even if the current model of Black Rock City is unscalable, it is certainly possible to create multiple versions that can run in parallel and independent of one another.

I admit that my musings here might seem quaint and even naive. Burning Man could completely collapse in the coming years should "tourists" start to dominate the city instead of actual contributors. It may even open up to corporate interests who will set up shops, a development that would completely undermine the concept. Such a development would truly kill the spirit and point of Burning Man in an instant. Or perhaps the idea of a permanent get-away place is not really a desirable or worthwhile goal. But we won't know until we try.

In the meantime, as Burning Man continues to fascinate, it's nice to dream of where it might take us.
