The lander was initially offered a 100-Watt RTG by Roscosmos that would've let Schiaparelli work for a year, but Russia's export regulations were so complicated and tortuous that they switched to a battery for 2-8 days of operations. I thought dealing with US ITAR regulations were bad.
Atmospheric water on Mars is plentiful enough to make clouds and is involved in the seasonal atmospheric carbon dioxide evaporation / condensation cycles. However, since it's pretty scarce, in situ measurements of atmospheric water would be helpful.
