Atv # Oil Checked: all ATVs almost full

Atv # Fuel Used Gals: None

Atv # Tires Status: all ATVs OK

Atv # Hours Used Day: We used #1, #2, #3, #4 for 1 hour

Atv # Notes and Comments: ATV No.4 which had broken parking

brake Ken looked at and he is requesting permission to

adjust 1 nut and 1 bolt that the parking brake cable goes

to which will tighten and fix the parking brake. Ken can

get pictures of the exact nut and bolt later if needed.

Summary of Engineering activities: 4 ATVs were used for EVA

and these are in the same condition as last time checked. We

didn’t have time to look into EVA backpack charger today

so we’ll do it tomorrow following Paul’s instruction we

got yesterday.

Questions and Concerns to Mission Support: We got new

situation about the problem of loft water pump from

yesterday. Yesterday night after CapCom, the

frequent pumping stopped right after the toilet was

flushed. Then today, it started pumping again and stopped

after the toilet was flushed (the pump ran about

5 minutes). We assured every faucet in HAB was shut off. We

haven’t checked the filter yet because the pump is doing

ok now, but we can check it tomorrow if you are still

suspicious of the filer.

Water: Thank you for passing down our request and we’re

waiting for the refill.

Gasoline: Thank you for passing down our request

and we’re waiting for the refill.
