Probably the usual aerospace stack: C/C++ and Ada doing the heavy lifting. Since memory is no longer a (significant) space constraint in 2021, I suspect other high level languages are also used for the non-critical parts of the system.

Is this definitely true in the context of astronautics?

The main computer of Perseverance (and Curiosity) has 256 megabytes of RAM. Which is only twice of what Spirit and Opportunity had so I wouldn't call this a significant increase. (Even Pathfinder had 128 in 1997 but wasn't a rover.)
