 A CubeSat is a really small satellite, a 10 centimeter cube. We have our thrust cells which are the 3D printed parts that you see here and then there's a computer on board as well as a battery on the bottom and they're all connected wirelessly through to our computers. It's compact, it's very low power and it's green since it uses pure water as propellant. There's no volatile chemicals involved so it makes it safe to bring on to the space station. The inlet is filled with water. There is a straight throat section to the nozzle. There are two heaters to heat the water's meniscus. When they are heated to approximately 50 degrees C, this triggers vacuum boiling of the water which creates water vapor providing thrust. Small thrust is critical because anything that you start moving you'll have to stop. If you're trying to adjust the orientation of a satellite you want to use as little amount of propellant as possible to turn it because you'll have to start it turning then you'll have to stop it turning. To be able to do that you need to have highly controllable attitude control systems like this micro propulsion device. We are able to provide that with this system. We're now trying to instead of just having a theoretical thruster we're trying to actually make it and see how controllable we can make it.
