As you will have already found out the Raspberry Pi (the computer at the heart of the ISS-Above) does not come with an on-off switch.
Just like any computer – they don’t like it when the power is just pulled from them without doing an orderly shutdown.
If the power is lost suddenly this can (sometimes) corrupt the SD card containing the ISS-Above code).
The best solution is to clone / backup the SD card to your computer. This will allow you to quickly restore the setup to your SD Card if it ever gets corrupted. This will only take 10 minutes and is HIGHLY recommended (otherwise tears and upset might be in your future).
You will need 8GB of space for the backup (the size of the SD card)
– although you can Zip (compress) the backup file for safekeeping and the file will be about 800Mb in size).
If you have a windows based computer follow these instructions.
If you have a Mac use these instructions.
This is avery helpful page, I appreciate that you gathered it together. FYI: Here is another way to make a back up on the Raspberry Pi. https://learn.adafruit.com/adafruit-raspberry-pi-lesson-1-preparing-and-sd-card-for-your-raspberry-pi/make-a-backup-image
