Stars - the number of stars that a project has on GitHub. Growth - month over month growth in stars.
Activity is a relative number indicating how actively a project is being developed. Recent commits have higher weight than older ones.
For example, an activity of 9.0 indicates that a project is amongst the top 10% of the most actively developed projects that we are tracking.
cFS
- NASA CoreFlight System (CFS)
- Examples of excellently-written projects.

C programming jobs?
I definitely recommend looking at https://github.com/nasa/cFS for some great pure C coding.

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):
https://github.com/nasa/openmct - web based mission control software
-
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).

[ANN] Summer Internship at NASA Ames Research Center
The student, if selected, will be working on extending our capabilities to test cFS/ROS/FPrime applications, especially those using Ogma and/or Copilot for monitoring. Both Ogma and Copilot are open-source software written in Haskell.

I want to learn Haskell, but...
For low-level embedded, you have Copilot!

[ANN] Copilot 3.12
Current emphasis is on improving the codebase in terms of stability and test coverage, removing unnecessary dependencies, hiding internal definitions, and formatting the code to meet our new coding standards. Users are encouraged to participate by opening issues and asking questions via our github repo (https://github.com/copilot-language/copilot).
