How NASA could have prevented a $200m crash with Julia's type system

It’s my first data science-related youtube video. I had some fun making it.

Maybe they can use Julia now to come up with a time machine and go back to 1999 to prevent the crash? Hopefully the Julia type system can help them take into account for leap seconds and so on :wink:

Certainly wouldn’t the GC in Julia cause more problems in a real time system like this?

In this case, the issue was not in the on-board software but in the ground segment. Flight dynamics calculations are usually done offline, so no real-time requirements there.

I am almost sure the calculation were done offline first.
