   About 10 hours later both the hot and cold sides have heated up. Why?   
   The sunshield has started to deploy for a few days and deployment should   
   be completed at launch +5.5 days (in a few hours). My guess is that it   
   was launched with a limited stock of coolant that has boiled off and   
   that the sunshield will take care of keeping it cool now.
