With the Genspace business and other stuff I’m working on picking up steam, it’s getting increasingly difficult to come up with decent enough blog posts these days. I’m still not sure whether this is a good thing or not. I love being busy pursuing my dreams, but writing is about the only thing that’s keeping me sharp, so that worries me a little. Maybe I’m slowly slipping into some state of waking coma…. Either way, I’m doing some really interesting things, so I might as well have a record of some of them here.
Genspace is in full swing, and Ellen’s busy running her biotech crashcourse, with other group-wide projects planned out already. Who would have thought we’d actually have a functioning biotech lab in NYC two years ago? Kudos to the people who stood by us all this time. Just having a lab is not enough though, we’ll be introducing some pretty awesome projects soon, just stay tuned!
I have so many things I want to write about now that I’m finally sitting in front of a computer and logged into my blogging account… But good things need time to mature, like hot pot. So I think I’ll just write about that one thing I’m supposed to talk about in this post 🙂
So we (me and Oliver) are planning to launch a high altitude microbial sampler into the stratosphere and do metagenomic analysis of whatever the samples we can gather from there. Right now I’m thinking of about 25~30km altitude, which should be around temperature range of -50 ~ -20 degrees C, which is really cold but not quite as cold as the furthest reaches of antarctica. Just to give you a scale of how high we’re going, latest version of Boeing 747 has top service ceiling of about 13km altitude. Our device will be flying at or above the double that altitude. Here’s an interesting picture of the Earth taken around 20 km.
Now simply launching a weather balloon into the stratosphere with some minor circuits, GPS and a digital camera would be simple. In fact, if it’s all I wanted I can just walk out there and launch my own balloon-sat right now. Yet, what’s the point in doing what everybody else is already doing, am I right? Now that we have a working biology lab we need to do something to bring my love of space together with my love of biology. Which means microbiome sequencing using samples taken from the above.
You see, there’s practically no real research data on the microbiome of the high altitudes. Considering the resilience of life (if you throw bunch of fruits out into the space from ISS, they’ll survive -kind of) and interlinked atmospheric conditions of the planet as a whole, we personally find it impossible to think that the realm of high altitude is totally devoid of life. There are papers out there tracing back to the era of the cold war suggesting that the maximum height of the planetary biosphere might in fact reach far beyond conventional height, with some evidences suggesting spore presence at mesosphere (~80km).
In order to have at least modestly reliable results from our experiment however, we need to design a device that can remain sterile to and from the stratosphere that will function despite heavy shaking, blistering cold, and falling. So far we’ve been making good headway into design and building of the device (Oliver is practically a McGuyver, with PhD in molecular biology) but it’s been a whole lot tougher than simply throwing together balloons, parachute and a camera that most of these projects tend to do. I’ve accumulated some interesting resources and research results during the course of the project, and will be uploading it to the net soon so that other people can follow in our footsteps and do their own high altitude sampling as well. Maybe it would be possible to grow this into an international program of sorts, considering the nature of the kind of organisms that might be found in the stratospheric range (if we find anything at all).
Recently we launched a simple tethered balloon sat to take pictures of Brooklyn from above. The contraption really had nothing to do with the sampler we’ll be launching, but it still gave us a good feel for what the real launch in the future might feel like.
The balloons were attached to a simple digital camera, a 1.99 semi disposable that took really horrible pictures. I’ll try to find a good one or two and post it later.
We launched the balloon on top of the Genspace building. The weather condition was really great, not too much wind at all. The sunlight was beautiful as well.
I’m one of those kids who used to stay up late at night thinking about the space, the high sky where the deep blue voids split over a thin red line of the sun rising, or setting somewhere over the distant part of the planet. Really, to this day the images still have the power to stir my heart, and make me feel like a human being. This is a meager start but who knows, maybe somebody’s already working on a synthetic biology satellite design that might one day take to the skies 😉
