So many fascinating facts about this! Did you know this had used gyroscopes to calculate the position and orientation of the spacecraft in orbit. It was designed to operate in the harsh environment of space, where temperatures could range from -100 to +150 degrees Celsius. And the thing only weighed 10kg! And super duper reliable I believe it had a mean time between failures of about 10,000 hours. Old yet still so impressive! Thanks for this!
