Notes And Comments: 

Today ATV #2 was used in order to assess it's status, since last time it was used there were issues. It is confirmed that the same issues 
are there: It is only working on the reserve tank. Towards the end of the EVA already close to the hab, it stopped and could not be 
started again. In the beginning of the EVA the main tank was 3/4 full and by the end it was almost empty.
 
Summary of Engineering activities:

Questions and Concerns to Mission Support: Do you have information on how the ATV's reserve/main tanks work? How are they 
connected? 

Can we be re-supplied with ATV fuel?
