It actually seems like a clever system.

published in 2017 mentions “event-driven science operations,” which is pretty much exactly how the documents describe the JavaScript-based system., saying that it can hold somewhere between 58.8 and 65 gigabytes of actual scientific data. Wait, did I forget to mention that? Yes, this telescope’s solid state drive has around the same capacity as the one that was available in, we’re not here to talk about the JWST’s storage.

Well, NASA’s document says that this way of doing things gives “operations personnel greater visibility, control and flexibility over the telescope operations,” letting them easily change the scripts “as they learn the ramifications and subtleties of operating the instruments.

If you’re still worried, do note that the Space Telescope Science Institute’s document mentions that the script processor itself is written in C++, whichknown for being... well, the type of language you’d want to use if you were programming a spacecraft. And it’s obviously working, right? The pictures are incredible, no matter what kind of code was run to generate them.

for being so slow and wishing that someone would just blast JavaScript into space, you can remember that NASA has, in fact, done that.
