NASA writes mission-critical flight software in C.
And the rules are absolutely INSANE.
> No recursion. Ever.
> Every loop must have a provable upper bound.
> No dynamic memory allocation after initialization.
> Max ~60 lines per function.
> Minimum 2 assertions per function.
> Every return value must be checked.
> Zero compiler warnings allowed.
> Daily static analysis. Zero warnings there too.
> No function pointers.
> Restricted pointer dereferencing.
This is how they write code at NASA / JPL for mission-critical systems.

The first extended mission began in August 2021 and ended September 2025. There might be an second extended mission (EM2) starting in October 2025 according to https://t.co/O7bCoci9Qr
