Robotic Scout To Survey Arctic Ice
Roland Piquepaille writes "The Meridian unmanned aerial vehicle (UAV) is a single-engine research aircraft with fixed landing gear designed by engineers at the University of Kansas. According to Technology Review, it will be used to see what happens beneath the Antarctic and Greenland ice sheets. Two units are currently being built for a cost of about 3 million US dollars. The Meridian will fly for up to 13 hours over a distance of 1,750 kilometers. The first flight over Greenland is forecast for next summer, and a second flight will take place over the Antarctic later in 2008."
get tagging, this is your daily dose of roland. if you are unlucky, there might be another roland story in a couple hours.
That may be true, but maybe it is this kind of thinking that lies at the root of the problem. A single car trip (drone flight) doesn't make a difference. If enough people think like this (it seems that currently a lot of people still do) and you've got a pretty big problem at your hands. In this special case however there may be a point to be made of the reward in understanding justifying the cost in environmental impact.
You can't take the sky from me...
Seeing as the planes will be launched in the summer, when daylight hours are the longest, why not refit that solar-powered plane that flew 52 hours straight (http://hardware.slashdot.org/article.pl?sid=07/09/10/1917254) for cold-weather flight and mount the survey equipment on it as well? I assume that the researchers don't need the plane to fly for more than a full day at a time. Unless maybe the sun is too low in the sky for solar panels to get enough power?

No idea, a lot would depend upon the time of year, of course. But when you're sending a multi-million-dollar aircraft over a few thousand square miles of ice, you would probably want a more reliable power system. I don't know how much power the radar equipment on the thing needs, but that alone would probably eliminate a solar-powered craft.
The higher the technology, the sharper that two-edged sword.
