Whilst I realise that it would eat into the weight budget of such landers, I reckon adding a fuel cell with enough fuel to last through the lunar night, which keeps the lander and its batteries alive, should be a standard and integral part of such craft.

Of course, that would mean taking less science with it, and increase the cost of the lander, and quite possibly if I can think of such a thing, engineers more clever than I am have already considered such.

Still, congrats to the team for managing to at least soft land on the moon. No doubt they'll be learning a lot of lessons from this mission.
