@65dBnoise I've definitely heard of other planned missions where the raw data would overwhelm any existing downlink, so the spacecraft has to be smart enough to filter out relevant data. still makes my skin crawl though; especially with astronomical data, it seems like you never know all the questions to ask about your data when you gather it

True. I can see how most (all) of the data from e.g. the JWST has to be downloaded, since those data *are* the product. But there are situations where this may not be the case, e.g. planing next sol's drive for a rover may require images from the engineering cameras chosen to show a certain direction. Making frequent 360° panoramas (thousands of images) may be feasible if they're kept remotely (cheap storage), but infeasible if they all have to be sent to Earth (expensive comms).
