Questions, concerns and requests to Mission Support:

* We had an Internet problem last night which prevented us to send the operations report to CapComm. It solved itself at around 10am this morning.

* We overestimated the static water tank capacity, and after checking the level properly with a rope and measuring volumes we reestimated its current level. We will try to diminish consumption as much as we can, but it is already very low and we are investigating other reasons.

* The water pump leak is at a plastic joint. To fix it we would need to stop the waterflow and replace the joint with a new one. We will try to document further the following days. Attaching a picture of the pump with the mail (faulty joint is in red, and you can see that water has been leaking for it).
