Summary of suits and radios:
EVA# 3 crew intended to use Space suits #2, #3, #4, and #6 but ended up using #1, #2, #4, and #6 due to less charge on #3 (5.7V). We figured it was due to the fan being kept ON at low mode after use last time which was consuming the battery. I have made a note of this and will make sure to check for the suits post-EVA and make sure such a mistake does not happen in the future.
No issues with the radios used for EVA #3.

Questions, concerns and requests to Mission Support:
EVA #003 crew exited through the engineering airlock as the main airlock had malfunctioned while opening it. The main airlock was tightly closed due to the windy conditions observed the day before which led to the harness hook being stuck on the inner door handle. The crew tried opening it but it did not open in time and hence the EVA crew had to use the engineering airlock to exit the Hab. The Hab crew had to cut the harness (running through the inner door) because the crew couldn’t open it at all and the main airlock access is needed for the EVAs in the future.
After returning from the EVA, I accessed the situation and thought of two options to address it but I would need your advice on it:
– Harness going around both the outer door handles, pulling in through the inner door, and securing using the hammer as the length of the harness is not enough for the harness hook to lock on the inner door handle (as shown in the pictures attached) OR
– Change the harness to a new one and have a sufficient length for the harness so that the harness hook locks on the handle as before.
