Eight kilometers of cables (nearly 13 km) connect the electrical system on board and more than 50 computers control all ISS systems. The software in orbit monitors about 350,000 sensors, thus ensuring the health and safety of the crew and the station itself.
On Earth, there are more than three million lines of code to handle more than a million and a half lines of code. of flight software …
