A satellite watching the Earth produces vastly more data than it can transmit.
The link to the ground is narrow, the passes over a ground station are short, and most of what the sensor captures is discarded or waits for hours to come down.
The bottleneck is not the camera but the pipe.
Processing the data where it is collected changes that.
If a satellite can run the analysis on board, what comes down is an answer rather than a raw feed, which is smaller, faster and more useful.
