DARPA's ASPARA systems are the latest piece of unmanned aerial vehicle technology aimed at supply essential goods and products to incredibly remote areas. What sets the ASPARA systems apart from other drones is that they aren't designed to be durable. Just the opposite, ASAPAs are intentionally designed to make only a single flight over the course of their lifetimes.
The system is part of DARPA's Vanishing Programmable Resources initiative, which looks to develop self-destructing electronics in order to prevent sensitive military equipment from falling into the wrong hands. As such, ASPARAs are made out of heavy duty cardboard with biodegradable circuitry; they are just strong enough to complete long-distance cargo flights, but too flimsy to be used more than once.
Once implemented, the systems have the potential to be an inexpensive means of delivering things like medical samples to isolated areas.
