"Would you like to have your own spacecraft in space?
I'm Zac Manchester, a graduate student in Aerospace Engineering at Cornell University. Over the last several years a few collaborators and I have designed, built, and tested a very tiny and inexpensive spacecraft called Sprite that can be built and launched into low Earth orbit for just a few hundred dollars each!
The Big Picture
My goal is to bring down the huge cost of spaceflight, allowing anyone from a curious high school student or basement tinkerer to a professional scientist to explore what has until now been the exclusive realm of governments and large companies. By shrinking the spacecraft, we can fit more into a single launch slot and split the costs many ways. I want to make it easy enough and affordable enough for anyone to explore space."
"KickSat is a CubeSat - a standardized small satellite that we can easily launch. It is designed to carry hundreds or even thousands of Sprites into space and deploy them in low Earth orbit. The Sprites will be housed inside KickSat in several spring-loaded stacks and held in place by a lid. A radio signal transmitted from our ground station will command the lid to open, releasing the Sprites as free-flying spacecraft.
After the Sprites are deployed from KickSat, we will track them and record their radio signals using a worldwide network of amateur ground stations to demonstrate their communication capabilities. We will also gather data on how long the Sprites stay in orbit and how well their electronics hold up in the harsh space environment.
Because we will only launch KickSat into a low-altitude orbit, we can guarantee that all of the Sprites will re-enter the Earth's atmosphere within a few days or weeks, leaving no trace of space debris. KickSat itself will last somewhat longer, but should burn up in the atmosphere within a few months."
