So this is our other thermal vacuum chamber. Other than the way it is heated and cooled, the big difference, and the size, and the neat part about this one is that is has a solar simulator attached. So the solar simulator provides a 12inch by 12 inch square in the chamber that is equal to the intensity of the sun when we are in LEO (lower earth orbit), which is AMzero, 1,365 watts per meter squared. On earth, in Ohio, if we go outside, hopefully it’s sunny, if it is sunny, we’re not seeing that intensity. So having a solar simulator allows us to fully test our solar panels. Right here is a solar panel without the cells attached, but you can see the spots that they will be attached. When we have the solar panel in the stand, we put it in the chamber facing this black box and then the entire solar panel is illuminated with the sun. And we’re able to do characterization of our solar panel, making sure that the panel itself is producing the power it’s supposed to, but then also, when the solar panel is integrated with the rest of the satellite, then we can verify that we are able to properly charge our batteries from the solar panel; rather than charging our satellite from the wall outlet. This allows us to do one half, part of our full testing to make sure that it will actually live on its own in space.
