ORBITER-FORUM will be temporarily closed at 2026-07-23 18:00 UTC while we complete some OF maintenance tasks. The amount of downtime is expected to take up to one hour, but probably less.
Flight day 4:
With a crew leaving the sleep station at 66:41:30 GET, the day featuring the first EVA of the Apollo program is starting. Need to test those PLSS backpacks! Activities for FD4 were as follows:
Tunnel pressure verification & equalization
G&N Power up (CM)
Tunnel & LM hatch opening...
Flight day 3:
With a wake up at 39:02:00 and another proper but this time not very restfull sleep cycle, flight day 3 started, finally featuring the first LM activities to be performed on LM-3 "Spider" in space:
Tunnel pressure verification & equalization
G&N Power up (CM)
Tunnel & LM hatch...
Flight day 2:
After completing the first "proper" sleep period of the Apollo program, flight day 2 started. The following activities were to be performed:
G&N power up
SPS-2 burn
SPS-3 burn
SPS-4 burn
G&N power down
G&N power up:
Procedures for G&N power up started at GET 18:50:00, with a CMC...
Hello all,
It´s again time for another Real Time Simulation debrief, this time for Apollo 9, wich we started on January 7th and concluded on January 17th. I continue to do these debriefs as I think that they provide usable feedback for NASSP´s users and the dev team.
For Apollo 9 I considered...
One quick question I did on the chats, that I will ask here again so it persists here.
For 9´s tansposition and docking, what is the correct pitch rate after launch vehicle separation?
Best regards,
Dear all,
I am finally on a kind of routine of apollo realtime simulations.
One year ago we completed the (second) first one, Apollo 7 and now I am preparing for the challenge of Apollo 9. It had to be delayed two months, so it will liftoff on january 7th at 11:00 CET (Central European Time)...
Hello,
Maybe some of these quicksaves I did during my second practise run for 9 help? Note that they are generated running the release 1944 of NASSP 8 beta.
Best regards,
Hello, thanks for the comments. I proceed to answer:
Q1: Virtual cockpits have "seat positions" and also "view positions" (I think they are called that way). What you see me do is to change the view position, and for that I use the combination Control+Alt+Cursor (Left/Right/Up/Down).
Q2: Yeah...
From what I heard, they didn´t came as far down the "checklist" as during this countdown during the wet dress rehearsal, so maybe that is why they didn´t catch the #3 issue.
Hello,
I think, IIRC, during that timeframe we were talking about a procedure for the AGC so that the attitude doesn´t get into Gimbal Lock during the sleep period.
The procedure was "created" during this RTS run, based on @Thymo ´s knowledge; maybe he can help you more on it, as I cant find...
Screenshots from my Apollo 8 RTS; I will start with the non lunar day photos; because on the lunar day, there are a lot of photos :P

Attaching quicksaves for the Real Time Simulation run. Names are processed as best as I could. Also on the zip are the raw quicksaves.
I hope they are useful!
Flight day 7:
Flight day 7 started with a awake crew at 144:00:00, and consisted in the following activities:
MCC-7
Entry preparations
Lunar entry
Post splashdown & crew egress
Change from FD-6 to FD-7:
PAD for MCC-7 was obtained at 143:18:30 and was as follows:
A preliminary Lunar entry PAD...
Hello,
I believe that this behaviour is normal. You should not get the RCS jets to fire during the Cold Fire test, as this test is intented to verify the ACA/TTCA signals, and check that they are correct. You check both rotation (ACA) and translation (TTCA) and verify the DSKY for signals...
