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.

- 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.

[ANN] Copilot 3.12
Among others, Copilot has been used at the Safety Critical Avionics Systems Branch of NASA Langley Research Center for monitoring test flights of drones. It also serves as a runtime monitoring backend for the requirements elicitation tool FRET (https://github.com/NASA-SW-VnV/fret/), via Ogma (https://github.com/nasa/ogma).

[ANN]: Copilot 3.10 - Runtime monitoring
Understanding these properties can get hard. Using a high level language as opposed to just C is very helpful (we review the code of flight systems with sometimes 4-5 people in the room and it's not trivial at all what it is doing or to show that it is correct). But even streams can sometimes be hard to understand for very complex monitors. We've also built Ogma (https://github.com/nasa/ogma) so that people can write properties in structured natural language, or transform other languages into Copilot (and then C/whatever).
