Is it true that Huygens ceased transmission less than 2 hours after
touchdown? Whilst it was a magnificent achievement to travel so far and
land perfectly, it seems a great shame that the probe was so short
lived. I'm suprised the designers didnt make it rugged enough and
powered enough to survive several days.

Why?
It had a low resolution camera, and all the data from that had already been
recieved.
It would have needed a bigger transmitter, bigger battery, ...

All that would have been gained would be atmospheric pressure and
identical pictures.
