Your own satellite aloft for $8,000

TubeSatIf SpaceX are out of your budget range, and you’re not willing to wait for laser propulsion to mature to commercially viable levels, you’d be forgiven for thinking that you were bang out of affordable options for launching your own satellite into orbit.

Not so – thanks to Interorbital Systems, you can buy a TubeSat 750-gram microsatellite and launch space for it on one of the company’s Neptune rockets… for just $8,000.

Since the TubeSats are placed into self-decaying orbits 310 kilometers (192 miles) above the Earth’s surface, they do not contribute to any long-term build-up of orbital debris. After a few weeks of operation, they will safely re-enter the atmosphere and burn-up. TubeSats are designed to be orbit-friendly.  Launches are expected to begin in the fourth quarter of 2010.

[…]

Each TubeSat kit includes the satellite’s structural components, safety hardware, solar panels, batteries, power management hardware and software,  transceiver, antennas, microcomputer, and the required programming tools. With these components alone, the builder can construct a satellite that puts out enough power to be picked up on the ground by a hand-held HAM radio receiver. Simple applications include broadcasting a repeating message from orbit or programming the satellite to function as a private orbital HAM radio relay station.

Sounds pretty limited in scope, doesn’t it? But then so do many generic technology platforms, right up until the point where hackers and other inventive types start testing their limits… and $8,000 isn’t a completely unreachable investment for a small clade of geeks with a big idea, or for an organisation with less savoury motives. If nothing else, we may see some sort of orbital-broadcast pirate radio revival… [via SlashDot; image courtesy Interorbital Systems]

The new terrorism: domestic, economic, environmentalist?

burnt-out carVia Chairman Bruce comes news from Berlin, a city whose rapid rate of change and gentrification is escalating tensions between the far right and radical left… and those of no political affiliation at all. The last six months have seen a wave of car-burning:

During the past six months, more than 170 cars have been destroyed by fire in Berlin and police confirm conservatively that 93 were politically motivated attacks.

A mysterious, single page website, brennende-autos.de (Burning Cars of Berlin), shows the number of cars set alight and where the crimes occurred, revealing clusters in ‘‘richer’’ areas, or in suburbs where gentrification and redevelopment are changing the demographic of local neighbourhoods.

Mysterious indeed. Is the site run by the car-burners themselves? Their supporters? Their ideological opponents? Berlin being a traditionally bohemian city, it may just be someone’s idea of an art installation.

According to a spokeswoman for the Bundesamt fur Verfassungsschutz (the Federal Office for the Protection of the Constitution), there has been a measurable increase in left-wing extremist action, including the targeting of police and the property of businesses perceived to be involved in military or ‘‘imperialist’’ activities.

DHL, a company involved in logistics for the German armed forces, has been a recent target.

‘‘It is not just anti-militarism we are seeing … it is anti-imperialism, a catalogue of anti-things … anti-fascism, anti-gentrification. The people we are seeing are the so-called ‘autonoma’, people operating in groups without hierarchy, who are not well organised and so classical anarchy is in the background of their thinking,’’ she says.

[…]

Police cars, too, are being targeted. The favoured method is to use the slow-burn barbecue fire starters, which take time to smoulder and provide plenty of get-away time for the perpetrators.

That could have come straight out of any near-future urban dystopia or cyberpunk novel you care to name; as traditional party-based politics drifts further and further from being able to represent the fragmented ideologies of populations, angry people will find their voice whatever way they can.

And as economic pressures deepen over time, we’ll probably see similar events cropping up in other crowded and under-funded cities across the Western world… so if you’re not already following John Robb’s Global Guerrillas blog, now may be the time to start. [image by Jacob Davies]

Your vat-grown burger will be ready in a decade, sir

brunch burgerWe’ve mentioned the potential of vat-grown meat here before, but I thought it worth bringing up again in light of an article at Wired UK that goes into more technical detail about the processes involved in growing cultured muscle for human consumption. [image by Marshall Astor]

“We’re developing a very simplified version of what we know as meat,” he explains. “The cells are grown in this dish within a growing medium and this unit is where they receive the electrical stimulation. These electrodes ensure there is an electrical current – about 1Hz – passing through the cells. To make these skeletal cells develop into muscle, they need to be constantly exercised, just like in the body.” This, he explains, is one of the scientific hurdles for in vitro meat that has not yet been fully addressed. “We can convert stem cells into skeletal muscle cells; however, turning them into trained skeletal muscle appears to be a little harder.”

They seem pretty confident about having a commercially viable product within a decade or so… but it’s probably going to delight the tastebuds about as much as the food you get on budget airlines:

“I don’t think we will spend a whole lot of time trying to replicate the taste of meat, though – that will be artificially added later. The food industry is already expert at enhancing taste – creating the right texture is the Holy Grail.”

Why complicate matters, adds Post, when you can nurture skeletal muscles to produce a simple, lean meat? Strip away the connective tissue, blood vessels and fat – as many of us do when we prepare a chicken breast prior to cooking it – and you’re left with a lean fillet of meat which consists of, roughly, 75 per cent water, 20 per cent protein and three per cent fat. Post believes that we are not too far away from producing this kind of meat on a commercial scale – ten years, perhaps. Convincing in vitro steaks and chops are probably a few decades away.

I guess the problem here is that the stuff will never sell until it comes out cheaper than real off-the-hoof meat. Once that price point is reached, however, I suspect the take-up rate will skyrocket.

Racism and genre fiction

This week is apparently International Blog Against Racism Week. During this year’s tumultuous RaceFail debate in the genre fiction community (and other smaller ones before it) I predominantly kept my mouth shut and tried my best to just listen; as far as middle-class white Western privilege goes, my life is pretty much a textbook case, and I’m sufficiently aware of that to know I have very little to add to the discussion that can’t be put far better by others with greater experience (not to mention stronger rhetorical chops).

But silence can seem like complicity, so this seemed like a good moment to come out and nail my colours – and Futurismic‘s, by association – to the metaphorical mast. I do my best to make Futurismic an inclusive place for everyone, regardless of race, gender or sexual orientation; I know I slip up sometimes, and I’ve been grateful to the handful of people who have politely pointed such incidents out to me (and will continue to be so in the future, I hope). My motivations for doing so will remain personal; there are those who may choose to see it as some sort of liberal guilt complex, and they might be right. Frankly, I’d rather live with that than the opposite; my insomnia’s bad enough already.

The important outcome of RaceFail for me – as for many others – was the uncomfortable but important realisation that, despite my best efforts to the contrary, I’m still racist sometimes. We tend to think of racism as an active verb, something that is by definition pursued deliberately, but that’s not necessarily the case. At very deep levels of our culture, we’re conditioned into a worldview that subconsciously reinforces the values of the past, even when we consciously embrace the ethics of the present. I guess you could say that – in what I hope and believe to be the majority of cases, at least within the genre fiction community – we’re racist by accident rather than design.

The good thing about making mistakes is that they give you an opportunity to learn and to improve yourself, if you have the will to do so. When I witnessed my first internet spat about racism in genre literature, I was rather taken aback – first and foremost because science fiction fandom had struck me as the sort of community where racism would be unlikely to occur. After all, it’s the literature of the future, of progress, right? Well, not entirely; I came to fandom quite late in my life, but I still came with a whole load of naivete. I very much suspect I still have a lot of it to lose.

But more recently I’ve come to see RaceFail and similar debates as something that actually confirms genre fiction’s progressive spirit. When I think of the other subcultures I’m closest to – particularly rock music – it becomes obvious that, by comparison, the genre community’s ability to muster enough voices against the status quo to make themselves heard is actually a very rare thing. Rock music is an intrinsically racist and sexist culture; not through deliberate choice in the majority of cases, but because it’s a reflection of its demographic’s attitudes. That peer pressure produces a powerful cultural inertia; try finding a well-trafficked rock music forum online where you can have a debate about the position of women in rock without rapidly being drowned out by posts saying whether or not the postee would consider sleeping with the woman in question. If you do know of one, please let me know about it!

Perhaps it’s because of its comparatively small size, or its long lifespan, or just the fact that it was one of the first fandom communities to really take to the multicast communication platform that is the internet… but I think the genre fiction community should be proud that we have debates like RaceFail. Sure, they can get pretty nasty; people on both sides of the fence tend to get hurt, both personally and professionally, and that’s a shame. But personally I think it’s a good thing that we can fight across that fence – because it means the fence isn’t an unclimable and impermeable wall, as it is elsewhere.

I’m not doing special pleading for fandom here; there are surely many other communities where the same conditions apply, but I can only talk with any validity about those I have experience of. RaceFail doesn’t mean that the genre community can rest on its laurels, safe in the knowledge that it’s more open to debate and dissent on matters of racial and gender privilege than other subcultures; nor does it mean it’s so riddled with entrenched prejudice as to be beyond improvement.

What it means, I guess, is that it’s full of people who care deeply about many different things, but who have a common ground in their love of fantastic stories. It is my hope that this common ground will continue to act as a meeting space where folk on both sides of the debate can discover more about each other as people, as individuals. If anything is ever going to erase racism from our culture – the culture of fandom, and the culture of the world at large – it’ll be getting to know people who are different to ourselves, and coming to realise that difference is something to be celebrated rather than feared.

It won’t happen overnight. Hell, it probably won’t happen in my lifetime, or maybe even longer than that. But I believe every assumption questioned is a step toward the future – that’s science fiction’s message, after all.

Thanks for reading.

The metaverse: booming despite your absence

As if an invasion of psychiatrists desperate for work wasn’t hint enough, the metaverse is still big business. Despite the media furore over Second Life and other synthetic worlds having died off considerably, the virtualities themselves have not, as Victor Keegan at The Guardian reports:

Actually, they are booming. The consultancy kzero.co.uk reports that membership of virtual worlds grew by 39% in the second quarter of 2009 to an estimated 579 million. Not all these members are active but I can’t think of anything, anywhere, that has grown so fast in the recession this side of Goldman Sachs bonuses.

There’s another curious thing: Facebook and Twitter are lauded to the skies, but neither has found a way to make money – whereas virtual worlds such as World of Warcraft, Entropia Universe, Habbo Hotel, Club Penguin and Second Life are all profitable because their business models are based on the digital elixir of subscriptions and micropayments, a formula that other websites, including newspapers, would die for. Twitter makes the noise, Second Life makes the money.

If you think virtual worlds are a passing fad, look at the figures. Almost all of the 39% growth came from children.

It seems that many of the newer metaverse startups have learned from Second Life’s very public teething troubles, too:

In order to get a more streamlined experience, most of the new virtual worlds don’t allow users to make their own content. Twinity, which has just raised €4.5m in new funding, has a virtual version of Berlin and Singapore (with London still in the pipeline): you buy existing apartments or rent shops but can’t build yourself. Bluemarsonline.com – still in testing mode – promises much better graphics and more realistic avatars at the expense of not allowing members (as opposed to developers) to create their own content.

[…]

With technology moving so fast and a whole generation growing up for whom having an avatar is second nature, virtual worlds have nowhere to go but up. Only they won’t be virtual worlds – just a part of normal life.

Maybe more normal than normal life. After all, if we continue down the paranoid path of protecting children from reality’s every rough edge, the poor sods will still need somewhere to go and hang out.
