Lo-fi wi-fi network springing up from junk in Jalalabad

Paul Raven @ 03-03-2010

Jalalabad FabLab wi-fi reflectorOffered here as an extension of the arguments made by the Prospect Magazine piece I linked to the other week about the lessons to be learned from the last-minute low-cost solutions of slum residents and other disadvantaged social groups, Free Range International hosts a report from an MIT team working in Jalalabad, Afghanistan that describes how an injection of knowledge and expertise can accelerate local progress far more effectively than an injection of externally-managed aid money:

… the irony of the graphic above is particularly acute when one considers that an 18-month World Bank funded infrastructure project to bring internet connectivity to Afghanistan began more than SEVEN YEARS ago and only made its first international link this June. That project, despite hundreds of millions of dollars in funding, is still far from being complete while FabLabbers are building useful infrastructure for pennies on the dollar out of their garbage.

People are smart, adaptable; show them where they need to go, and they’ll find a way. What’s that old saw about giving a man a fish and feeding him for a day?

The post goes on to highlight the patient and painstaking work of showing the Afghanis that they need to work together to overcome their differences; a carrot and stick operation it may well be, but I’m guessing it’ll do more good than training up and arming local militias, and then expecting them not to fall back into old habits once your back is turned. All depends on whether you want to give these people their freedom or to take control of it yourself, I guess.


Who’ll be next on the Moon now NASA’s doing other stuff?

Paul Raven @ 03-02-2010

The MoonWell, the new NASA budget from Obama and chums has certainly got people talking… mostly about the fact that the dream of returning astronauts to the Moon is off the table for the foreseeable future [image by ComputerHotline]. Wired has snippets from the budget summary:

“NASA’s Constellation program — based largely on existing technologies — was begun to realize a vision of returning astronauts back to the Moon by 2020. However, the program was over budget, behind schedule, and lacking in innovation due to a failure to invest in critical new technologies,” the budget summary concluded. “Using a broad range of criteria, an independent review panel determined that even if fully funded, NASA’s program to repeat many of the achievements of the Apollo era, 50 years later, was the least attractive approach to space exploration as compared to potential alternatives.”

However, it’s not a massive close-down operation: NASA’s budget has actually been increased, but earmarked for more practical and pragmatic science research, “sustainable exploration”… and keeping some older projects on the books:

Part of that commitment will involve a reprieve for the International Space Station. Instead of being deorbited in the middle of this decade, the ISS will be treated like a national laboratory, and used to pursue research on materials and long-term human habitation in space through at least 2020, with additional construction, including new infrastructure, planned beyond the end of the shuttle program. The budget also includes money for an extension of the shuttle through 2011, which will allow for the inevitable launch delays in its remaining five missions.

io9’s Annalee Newitz points out that the prospects of the new budget are actually good for pro-exploration types, because it’s a realistic budget that eschews symbolic white-elephant achievements and glory-recapturing in favour of doing affordable things that will teach us lots of useful new stuff. She worries, however, about the fates of those whose expertise will be surplus to requirements now the Constellation project has been shelved:

One of the issues that concerns me the most is what will happen to all the talented NASA employees who have been working on Constellation and related projects. If NASA’s plan is to outsource the development of space vehicles that can carry human cargo, then thousands of jobs will evaporate. Florida alone anticipates losing 7,000 jobs when the Space Shuttle program ends next year. Earlier today Obama told reporters, “We expect to support as many if not more jobs with the 2011 budget,” but those will not be the same jobs. My hope is that some of this budget money that’s been allocated for private sector companies can also be used to place NASA engineers into private sector aerospace jobs. We need to encourage knowledge transfer from NASA to private industry. That way, aerospace companies won’t have to start from square one as they push humans into orbit.

Paging Ben Bova… Sam Gunn’s time has come, perhaps. After all, there’s nothing to stop private enterprise achieving a Heinleinian dream and setting up a kind of frontier town based on Helium-3 mining and fast-and-loose land claims… well, nothing apart from the same practical difficulties and vast expense that have kept NASA away for the last four decades or so, anyway. But those difficulties don’t seem to be deterring the people behind the Open Luna Foundation [via MetaFilter], which…

… aims to return mankind to the moon through private enterprise. Initial goals focus on a stepped program of robotic missions coupled with extensive public relations and outreach. Following these purely robotic missions, a short series of manned missions will construct a small, approximately 6 person settlement based on a location scouted by the robotic missions. This settlement will be open for anyone’s use (private individuals to government agencies), provided they respect our ethical conduct and heritage policies.

You’ve got to admire the chutzpah, if nothing else… but I think I’ll hold off investing any money in that operation for a little while yet. But it begs the question: if NASA’s putting the Moon on a back burner, who’s going to make it there next? Private enterprise libertarians like Open Luna? China, India, Brazil? Anyone?


Worlds enough, and time: NASA commitee says Mars too costly, asteroids more plausible

Paul Raven @ 26-10-2009

MarsEven someone who struggles as badly with their personal finances as myself would be hard pressed not to realise that NASA finds it hard to balance its lofty ambitions with the number of greenbacks in the jar on the mantelpiece. Now the Agency’s recently-appointed committee is saying the same thing in plain language: the money for a Mars mission just isn’t there, but more realistic goals like jaunts to asteroids and the Lagrange points can and should be followed up.[image by jasonb42882]

Now, I’d like to see manned Mars missions happen in my lifetime (as I’ve made plain here a number of times), but I’d rather that the planet’s biggest player in the space game got the maximum bang for its diminishing buck. As things stand now, everyone else follows where NASA leads, and while that won’t be the case for ever (or even for long, if you want to be a pessimistic realist about it), and I’d rather see them pushing the envelope steadily than trying to blast heroically through it. Watch the private space companies, as Brenda suggested the other day; those incremental baby steps soon start adding up.

And after all, there’s plenty of interesting stuff to do that doesn’t require a jag all the way to Mars. As the committee’s report points out, asteroids are easier to get to, and there’s still plenty they can teach us. Plus there are resources to be had; maybe NASA could balance the books a bit by slinging some or all of an asteroid back to Earth? A big lump of ice and minerals in close proximity to the home planet is the sort of thing a lot of the smaller fry would pay for a piece of, and it would be a handy thing to have in inventory for your own future works at the top of the gravity well (and beyond). And then there’s the the Lagrange points… depending on your focus, you could either do some good science out there, or get all Ben Bova on our asses with hotels and heavy industry.

Thinking pragmatically, the committee are right: Mars can wait, not just for NASA but for everyone. We should go, yeah, but we should go when we’re ready and able. As this rather charming infographic at BoingBoing shows, our success rate has been improving ever since we started trying to reach the Red Planet… but by trying to punch above our current weight, maybe we’re missing out on flooring some more manageable targets closer to home.


Project Icarus: an eye in the sky for just $150

Paul Raven @ 14-09-2009

The popped Project Icarus balloon on its way back to EarthIf the $8000 TubeSat kits we mentioned last month are still to pricey for your pocketbook, never fear – you can still muck about on the edge of space, provided you can scrape up a few hundred bucks. A group of MIT students under the aegis of the Icarus Project have managed to take digital photographs from 17.5 miles above the surface of the Earth using nothing but off-the-shelf components… for a mere $150. [via Hack A Day]

The GPS receiver was a Motorola i290 “Boost Mobile” prepaid phone with internet and GPS capability (set up with Accutracking to constantly report its GPS location).

We bought a AA-battery cell phone charger to sustain the phone’s power over the duration of the flight, and we used Energizer lithium batteries (rated to operate at temperatures are low as -40F) to power both this charger as well as our camera.

As a further safeguard against electronic/battery failure due to low temperature, we utilitzed Coleman disposable hand warmers (placed near our electronics) to help keep our equipment warm in the cold of the stratosphere.

We loaded a Canon A470 camera (bought used on Amazon) with CHDK open source software to enable a feature which allowed the camera to take pictures continuously (intervalometer). Using this feature, we set the camera to take a picture every 5 seconds at a 1/800 second shutter speed. With an 8GB card, the camera was able to chronicle the whole journey of the balloon from launch to retrieval. (~5 hours)

OK, so it’s not exactly the most complex payload ever sent aloft, but it’s a clear demonstration that ingenuity gets things done… as is the example of Armadillo Aerospace, who’ve just taken the Level 2 prize of $1million for the Northrop Grumman Lunar Lander Challenge with their Scorpius vehicle.

And given that NASA has been warned that it needs to constrain its goals unless it can increase its budget, that’s good to know; I’m more convinced than ever that the next big steps in space will not be achieved by government agencies, though they may retain a political space on the game-board by commissioning more prize challenges.


Dead Institutions Beat: home-study degrees on a shoestring

Paul Raven @ 09-09-2009

Will the university be the next institution to fall to the onslaught of the internet? Probably not just yet, but the brick-and-mortar halls of learning are going to suffer badly against start-ups like StraighterLine, which offers online PhD-designed all-you-can-eat higher education courses… for just $99 a month. [via MetaFilter]

StraighterLine is the brainchild of a man named Burck Smith, an Internet entrepreneur bent on altering the DNA of higher education as we have known it for the better part of 500 years. Rather than students being tethered to ivy-covered quads or an anonymous commuter campus, Smith envisions a world where they can seamlessly assemble credits and degrees from multiple online providers, each specializing in certain subjects and—most importantly—fiercely competing on price. Smith himself may be the person who revolutionizes the university, or he may not be. But someone with the means and vision to fundamentally reorder the way students experience and pay for higher education is bound to emerge.

In recent years, Americans have grown accustomed to living amid the smoking wreckage of various once-proud industries—automakers bankrupt, brand-name Wall Street banks in ruins, newspapers dying by the dozen. It’s tempting in such circumstances to take comfort in the seeming permanency of our colleges and universities, in the notion that our world-beating higher education system will reliably produce research and knowledge workers for decades to come. But this is an illusion. Colleges are caught in the same kind of debt-fueled price spiral that just blew up the real estate market. They’re also in the information business in a time when technology is driving down the cost of selling information to record, destabilizing lows.

Here in the UK we have something called The Open University, which operates under a pretty similar distance-learning/subscription system… but not at that sort of bargain price-tag.

Decoupling quality higher education from temporal and financial restrictions is potentially a very disruptive technological step – not just for the US or other Western countries, but for the whole world. Those restrictions are what has traditionally deterred or prevented the less privileged from competing on qualifications in the employment marketplace, and outfits like StraighterLine could theoretically help reverse (or at least stabilise) the widening gap between the world’s rich and poor.

Of course, the prospect of even more people with degree-level qualifications might well devalue them even further, at least temporarily; the sheer number of courses here in the UK has left the job market saturated with unemployable graduates who have little to show for three years’ work (or partying) but a big chunk of debt. But if people who really want or need a practical or in-demand degree – and, more importantly, who are willing to work hard and quickly to get it – find themselves able to bypass the old institutions, I’m guessing we’ll see a lot less people going to college or university as a way of deferring the initial plunge into employment; free markets work in interesting ways.
