I used to work for a software consulting firm and one of our clients was NASA. Nothing exciting, just replacing an expensive proprietary system written in a commercial language with an open source one used for analyzing data from the Parker Solar Probe (PSP) and the then to be launched Interstellar Boundary Explorer (I BEX).

The maths were so far beyond my two time community college drop out, barely graduated high school, self taught background I couldn’t even explain them. Fortunately we used paired programming and had enough mathemagitians on staff I never had to deal with the maths alone. My contribution was mostly UI and data visualization.
