Which programming language is used in space stations?
Don't know. Maybe their own customized language (Just a guess).
Something like C and C++ I guess. It's pretty probable that they create their own programming languages and use them.
A mix of C/C++/Ada Also: https://en.m.wikipedia.org/wiki/HAL/S
Are you sure that Ada is used in space stations? As I know, nowadays only Boeing is using Ada.
@Evil Dog You’re right, not anymore. Was used about 30-40 years ago 😉
