Questions and Concerns to Mission Support:

During the EVA, one of the headsets cable got broken near the plug. It had been fixed already with tape in the past (by previous

crews), but now it's completely separated. We can try to go ahead and fix it, but the damage seems irreparable.

I checked for the possibility of having the 3-plug electrical extension at the static tank hanging upside down. The conclusion is that it is possible. Please check attached picture and let me know you opinion. An easier solution would be to cover it with plastic foil, making a cone coming from the male cable (device inside tank) and going down the female plug.

Best regards,
