ExoPlanetSat nanosatellite to begin search for alien worlds next year
SETI's search for intelligent life in outer space may be on ice for the time being, but the search for alien planets that may possibly support life of some sort is now being bolstered by a number of new efforts. One of the latest is the so-called ExoPlanetSat nanosatellite developed by MIT and Draper Laboratory, which recently got the go-ahead from NASA's Cubesat Launch Initiative and is now set to hitch a ride into space sometime in 2012. While not quite as "nano" as the SIM card-sized satellites that launched with the Shuttle Endeavor, the smaller-than-a-breadbox ExoPlanetSat is still pretty tiny by satellite standards, yet it packs all the necessary optics and technology required for what's known as transit observation -- that is, monitoring a star for decreases in brightness, which could indicate a planet passing in front of it. What's more, while the launch of a single satellite is plenty to get excited about, the researchers hope that it lead the way for a whole fleet of similar nanosatellites that could greatly speed up the search for planets.
Draper Labs develops prototype Mars Hopper
The Mars rover, that self-propelled, solar powered box o' sensors 'n stuff that slowly inches along the surface (and battles the fierce environment) of the red planet may be a mainstay of space exploration, but it's certainly not the only way to get the job done. For instance, the kids at Draper Labs -- last seen in this space with their injectable nanosensor -- are in the process of developing vehicles that would (literally) leave traditional rovers in the dust. The Draper Hopper prototype is designed with a ducted fan propulsion system that uses compressed nitrogen gas to cover twenty-five miles in a few days or, at best, a few hours. By way of comparison, NASA's Spirit and Opportunity craft have covered roughly twenty miles since hitting the Martian surface in early 2004. Of course, the hoppers will have to bring fuel with them, so their lifespans will be cut drastically shorter than their wheel-based contemporaries, but we've always believed more autonomous vehicles should "live fast / die young," like Sid Vicious or James Dean. With any luck, we should see test flights by January 2011.
Tattoo-like nanosensor could monitor glucose levels, enhance your cool factor
Make no mistake, there are quite a few sophisticated ways to monitor one's glucose levels, but we're pretty certain we've never seen an approach as simple and as bodacious as this. Massachusetts-based Draper Laboratories has stumbled upon a new embeddable nanosensor that could, at least in theory, eliminate those painful pricks endured today by so many diabetics. The so-called "injectable nanotech ink" could be inserted under the skin much like a tattoo, though Draper's Heather Clark notes that it "doesn't have to be a large, over-the-shoulder kind of tattoo." In fact, it can be as small as a few millimeters in size, though if it were us, we'd use it as the perfect excuse in order to plaster our backs with Ice Climbers. Testing of the new approach is expected to begin very soon, though that usually means it won't be ready for humans until at least a few years later. Ah well, plenty of time to dream up the perfect design, right?[Via medGadget]
