I am working on a project for science fair that involves a deployable component that will not be heated on a CubeSat. I am trying to find data for the skin temperature of a satellite (or the ISS) over a single orbit. Averages and min/maxes are easy to find, but an actual temperature curve of an orbit has been elusive. Does anyone know where this data is available or what the search term we are missing is?
--------Edit: Thank you for all the responses so far. The deployable component is a digital display. For the project I am testing three options:
My science fair project is about finding out if these displays can withstand vacuum and the temperatures they will be exposed to. Our satellite is a 2U CubeSat and we expect the screen will be mounted 10 to 15 centimeters from the satellite once deployed. The glass of the display will be facing the satellite and the back of the display will always be facing the earth. The setup is to allow an onboard camera to take pictures of the screen with the earth in the background. My science fair project is about testing the suitability of these screens for the CubeSat mission. It is being launched from the space station and will therefore have approximately 15 orbits/day.
I already know the LCD is not a suitable candidate for deployment, but we are including it in our testing to demonstrate why.
Once de-tumbling is complete we expect pointing to be accurate to about 20 degrees and expect little rotation. On the deployable screen there are no plans currently to heat. The plan will be to operate it only in the window of the components operational temperature.
We are trying to find out two things with this question:
- What is a comparable temp range this screen will be exposed to (even roughly estimated) so I can test in the lab something that approximates these conditions (hopefully we can test something wider than worst case).
- We want to get some idea of the amount of time these digital displays will spend at a temperature within their operational range each orbit.
Also - as an aside, I have not been able to find an example of other digital displays in space (which makes sense, as who is looking at them...) but if anyone knows of an example it would be great to know about it.
