It is written here that before the final descent Rosetta was programmed for "auto shutoff" after reaching the surface of the comet, to prevent the possibility of the further communications in the case of unlikely survival.
What is the reason for wasting time in programming such a behavior? If the probe is no longer required, why cannot it just be abandoned? And maybe it could take a couple of extra pictures from the surface of the comet before that, or at least finish the transmission of data collected during the descent? And if not, then not, since the chances are low.
While the team of tele-operators costs money, the probe has been flying for many years. It would be strange to hear that it is not possible to afford this team for the extra month or two.
This seems so strange that I even suspect that the "auto shutoff" may be a kind of urban legend. Could this be true?
