[Operations Report – December 24th]

Crew 236 Operations Report 24-DEC-2021

SOL: 5

Name of person filing report: Pavithra Ravi

Non-nominal systems:

1. Suits and radios — the suit issue reported on yesterday’s report persists.

Notes on non-nominal systems: The backpack was opened and the voltage
across the battery leads was checked with a multimeter, yielding 11.48
V. Since this is not too far from the ideal value of 12 V, the issue
may not be with the battery. When the air was turned on to max, one of
the fans did not turn at all, while the second fan spun very slowly.
Nothing appeared to be burned or abnormal.

2. Toilet — the leaking issue persists when the water valve isn’t turned off.
Today, we attempted to fix the leak by reapplying Teflon tape to the
threading on the fittings near the leak spot. Then, we proceeded to
tighten the fittings once more and then we turned on the water valve.
After about an hour, the leak started once more, though now it is
dripping from a different spot. While the water was initially coming
out just behind the black fitting (shown in with the blue arrow in the
attached photo), now it is coming out where the black arrow is.
