Turns out the infamous Mars helicopter is running a whole lotta #FOSS (#opensource) software! @klintron has a good writeup here:
"Open Source on Mars: Community powers NASA’s Ingenuity Helicopter"
https://github.com/readme/nasa-ingenuity-helicopter
(It quotes me, but the rest of the article is great.)
We can conclude that a lot, maybe 100% of the software used on Mars is Free Software, unlike on Earth.
Mars 1 - 0 Earth 😔
