Orbiter Space Flight Simulator | NASSP | P23 Song, original edit

During our Real Time Simulations of Apollo missions, using NASSP (NASA´s Apollo Space Simulation Project) we did a bunch of runs of P23, trying to understand its technique.

P23 is a program used during cislunar navigation, to update the onboard state vector on the command module, so that in case of a loss of comm with the mission control center, the crew can have an accurate state vector to run P37 and come back to Earth.

For fun, I wrote a song. This is the original version, I performed another edition live during the last day of flight of the Apollo 12 Real Time Simulation.

Footage is from a video I recorded on August 2020, when I was preparing for the Apollo 8 Real Time Simulation wich we performed in May 2021. Song was sung in april 2024. (Although some verses were composed during the Apollo 11 Real Time Simulation )

Lyrics:
There´s a program in the AGC
To keep the crew entertained
Long hours of Translunar coast
We are getting big 06 49´s
P23, P23....
Getting behind the flightplan
P23, P23....
Wanna understand your technique:

Make sure to load in the right horizon
And don´t forget to grab the straight thing
When switching to SCS two jets on roll axis work better
Null your attitude rates and place the star
On the paralel line over the horizon
Check your attitude and rates and just perform a mark
Check the information
and hit PROCEED
If 06 49 gets high load it again and repeat!
As the mission clock moves forward
That is how you do
(ah)P23

(Oh, P23, Oh, P tweenty threeee)
P23, P23....
You help us get back home
In case of a Loss of Comm
But getting big 06 49´s

P23, P23....
Checking our state vector
P23, P23....
Wanna understand your technique:

Make sure to load in the right horizon
Use something straight as a reference (Straight thing!)
When switching to SCS two jets on roll axis work better
Null your attitude rates and place the star
On the paralel line over the horizon
