Paper Airplanes in Space

Some scientists in Japan want to make paper airplanes (origami planes, to be precise) and launch them from space, and see what happens as they come back to Earth. I'm not sure what to make of this... On the one hand it sounds neat - these scientists are pretty confident that, because of their small size, they won't burn up in the atmosphere, and that information learned from their "flight" might help design new spacecraft. On the other hand, paper airplanes are small, and therefore will be nearly impossible to track on their way to Earth, and will be very hard to find once they land. There's also something...weird, I guess, about research on paper airplanes getting $300,000 worth of research funding per year. There's actually a lot of complex testing that has been done and can still be done with the airplanes, so it actually does make sense, but it still just sounds weird.
