Resources for Space sector embedded programming
Nowadays there's a trend towards openness and reusability. There's frameworks like the NASA Core Flight System (cFS) and the NASA JPL F Prime framework. There's also workshops where all of us flight software engineers get together and discuss new research, trends etc: https://www.youtube.com/c/FlightSoftwareWorkshop

Ask HN: What open source projects go to space?
Core Flight System (cFS) https://github.com/nasa/cFS
NASA has a lot of open source projects including a bunch that don't "go to space" but are used in space related projects (check each project for contributor guidelines):

ANN: NASA's Ogma
Your best bet is probably to read the documentation of the project itself, as well as documentation from the associated projects FRET, Copilot (https://copilot-language.github.io/documentation.html, https://ntrs.nasa.gov/citations/20200003164), and cFS (https://github.com/nasa/cFS).
