NRL Satellite (ARDUINO IN SAPCE!)

I could ask 1000 questions because I find it very interesting what you did. Maybe my two most important questions:

  1. Did you write sketches with the Arduino IDE or did you only use the bootloader to upload program that you wrote in C or assembler? I mean will a digitalWrite() line of code be in space?

  2. Can you explain the space to earth communication? What kind of signal is used, how does the receiver look like and what tasks does Goldberg-1000 have?
