Hi and Happy New Year.
I started Apollo 9 to practice LM and rendezvous, I am now at day 4 at around GET 69h 30m when I am supposed to activate the LM and slowly moving the crew into it. (started from the Apollo 9 with MCC launch scenario).
When time comes to open the CSM tunnel hatch, after having done P51 IMU Orientation, I have all three crew members on SUIT FULL FLOW (300, 301, 302 pnls) with EMERGENCY CABIN PRESSURE – OFF (351 pnl) … and all are OK “green” on PAMFD.
At 69h 25m I do “LMP IVT to LM” from the CSM…so I go into the LM to open the hatch (the CSM hatch was already open before, just after P51). Once both hatches are open, I go back to the CSM and I “CONNECT the CSM O2 HOSES” -> not appearing in the checklist, but suggested by “you” during a similar question for my A11 previous mission, so I guess it is required also here.
1st question:
To open the LM OVH Hatch I need to put the “OVHD CABIN DUMP VALVE to OPEN, if I let in AUTO the hatch doesn’t open; is it normal? later in the checklist it is requested to put back to AUTO…
With the vlv to “OPEN” I carried out all the subsequent LM steps indicated by the checklist starting at T +69:25:00.
2nd questions:
While trying slowly these steps I saved often, and I also noticed that when I save a scenario with the “CSM O2 HOSES – connected”, upon reloading the scenario the hoses get somehow “DISCONNECTED”…I guess should not happen this? Anyway, upon reloading saved scenarios I was immediately reconnecting them by PAMFD before carry on other tasks ...
At about T +69h 42m I am ready to do the “ECS Activation EVA” and other tasks … finally I am back to the CSM to wait for the T +69h 55m MCC update, with the CSM O2 HOSES still connected, and at about +70h 4m I am ready to transfer the LMP to the LM ECS system (followed by the CDR immediately after), photo 1 show the cockpit status I got at this stage.
Up to this moment I have 300-301-302 in SUIT FULL FLOW, the “LMP to LM ECS” CSM checklist ask to put the RH SUIT FLOW vlv to OFF on pnl 300 (LMP side) and remove the LMP from PAMFD ECS page, I guess need only to enter CREW=2.
Next inside the LM I put in PAMFD ECS page crew=1 and LMP=in suit … from photo 2 the C&W lamps status and CO2 meter seems ok … but as soon as I turn the “LM SUIT ISOL vlv to SUIT FLOW” I got a CRITICAL yellow warning light on in PAMFD ECS page and the CO2 LM meter jump to 30 , see photo 3 and 4.
3rd Question: why the CO2 is so high, I used the hoses since the time I opened the hatches about 30-40min earlier …
When later on I am supposed to transfer the CDR into the LM ECS other issues arises;
4th question:
during the CSM “CDR IVT to LM” checklist (see photo 5) why 302 (CDR) should be to CBIN FLOW ? he is in the suit. Should not be put to OFF and than connect him to the LM ECS? (as before was done for the LMP and pnl 300?) ….
But as can be seen in the checklist, few items below, it ask for set pnl 300 to FULL FLOW? This is for the LMP which is already attached to the LM ECS, so he is not connected anymore to the CSM ECS … should not be the 302 panel, for the CDR?
5th question:
Finally during the “CDR to LM ECS” checklist it is stated “RH SUIT FLOW vlv – OFF” on pnl 300 --- should not be pnl 302 for the CDR?
In summary, after having completed the IVT of LMP and CDR should we have (?):
300 -> OFF (LMP);
302 -> OFF (CDR);
301 -> SUIT FLOW (as the CMP is still suited)
And in the LM both “SUIT ISOL vlv” to SUIT FLOW?
Anyway, I set the valves as indicated in my summary (overriding what stated in the checklist), and I got crew=1 in CSM, crew=2 in LM and CDR and LMP in SUIT, as in photo 6 … both CRITICAL … due to CO2 at 30ppm again … keeping going on doing further activities they both DIED (red message) after a while …
Anyway, I got CRITICAL yellow warning light on also the 1st time I entered into the LM, at time of the docked DPS burn,… but no CO2 alarm was there and after 20 min I got the green OK message on PAMFD, so I guess would happen like that also this time, so I pressed on with the others activities…but as said they both died.
6th questions (minor questions):
When asked to closed the LM hatch I was able to close it (even if the CSM O2 hoses were still connected) -> Ok I should have disconnected them before to closing it … but I forgot.
From the other side, once back into the CSM, when asked to close the CSM tunnel hatch if I didn’t disconnect the CSM O2 hoses the hatch didn’t close (which make sense to me as pipes are there…)…
As said, disregarding all I kept going on and after a while I got the message that the crew has DIED.
What to do? Or what I am doing wrong? If you need some scenarios let me know at which time.
Thanks for help.
