Hatch closure.

Crew is hot-miked. Onishi and Kim are starting to walk them through depressurization procedures.

I think the silver thing Kim is sticking to the wall there is a pressure gauge - suppose it makes sense that you'd want to make sure the pressure in the equipment lock doesn't move!

Around 8 psi in the crew lock, per the commentator.

Crew lock is now at 5 psi - pausing depress for leak checks.

McClain reports a 2-4 mm slit in the RTV on her glove (right index finger) during the initial glove check.

Ground teams are having her turn on her HECA so they can take a look.

That had to occur while she was in the crew lock...

HECA views of McClain's glove, although it's hard for me to tell what's reflection vs. what might be a slit through to the white fabric.

the prospect of another EVA ending before it begins...

Yellowstone10 · « **Reply #52 on:** 05/01/2025 12:42 pm »

Go to continue - no additional checks needed now, but McClain's been told to keep an eye on it.

Yellowstone10 · « **Reply #53 on:** 05/01/2025 12:46 pm »

Down to 3 psi.

EV crew is switching comms from Kim and Onishi over to ground IV Marcos Berrios.

Calling down initial tether configurations.

Yellowstone10 · « **Reply #55 on:** 05/01/2025 12:57 pm »

Pressure is now falling below 50 millibar (Jonathan McDowell's EVA start metric - about 0.7 psi).

Yellowstone10 · « **Reply #56 on:** 05/01/2025 01:01 pm »

Berrios mentions by way of reminder that there are 4 extended Ku outages of 20-40 minutes during the EVA during which they will not have video or HECA coverage, with the first starting in about 30 mintues. S-band remains go for audio comms during those periods.

Targeteer · « **Reply #57 on:** 05/01/2025 01:02 pm »

repeating my earlier report that there will be no TDRS 275/Z Ku coverage. There will be S band so there will be audio. 25-30 minute gaps cannot be blamed on 275/Z which is a gap filler between W and E coverage--gaps are usually 10-12 minutes. DoD is hogging one of the two...

Pressure less than 0.5 psi - go to proceed with hatch ops. (ISS Mimic is reading 8.9 torr.)

Why all the "data reviews"? These are not normal
