Here is the code that took Apollo 11 to the moon
Apollo 11 is considered as one of the most important space missions in the world. It was the first spaceflight that landed humans on the Moon. However, there was a computer responsibly for the entire flight and now, you can see its codes in the GitHub.
The interesting part of the code is that you can find some jokes. For example, there is a file called “BURN_BABY_BURN–MASTER_IGNITION_ROUTINE.agc”.
If you want to see the code, you can find it here ( maybe, you made your own rocket but you just need a software to handle things. Who knows? )
