Hold up. Do you have a Michael fic about the reader being an angel? Good lord, can you link me to it?

Yep! And I JUST posted part two.

Here’s part one

Here’s part two

Part 3 is coming probably in a week or two! (Maybe less if I feel inspired™)

Maneuver pads describe in detail, maneuvers carried out by the Apollo spacecraft, either for contingency plans, and mid-course correction burns. These were recorded from listening to the Apollo 8 mission on YouTube. I had to make the form for myself in Illustrator using the actual flight plan as reference and cross-check with the transcripts because there’s a lot of numbers.What’s interesting about the Apollo 8 mission is that MCCs 2 and 3 were cancelled due to the fact that the error was within the degree of uncertainty you have already. MCC-4 comes not long before Lunar Orbit Insertion.

Described on the right-side, top to bottom is the purpose or name, propulsion method (RCS,SPS/G&N), vehicles total mass (WT), SPS engine gimball trim(P,Y-trim), time of maneuver (Hr,Min,Sec GET), ΔV along x,y,z axes, required vehicle attitude at time of maneuver, Height apogee, perigee (or perilune/apolune in lunar orbit) in N.MI.(Ha, Hp), vector sum (ΔVT), burn duration (BT), ΔVC total change in velocity as ‘counted by the EMS ΔV display in ΔV mode, a cue that the computer uses to end the burn. This is followed by navigation information, sextant star(SXTS), shaft and trunnion angles that will yield said star if in proper attitude, boresight star(BSS, which uses the COAS ‘gunsight’ sight in window 2)to double check alignment, followed by the location of the star on the graduations on the reticle of the sight (SPA,SXP). LAT,LONG,RTGO,V10 are entry interface and landing information, only the ‘TLI+90′ Abort pad that I’ve filled out has this information included in the pad, as it was a burn that would bring the spacecraft home quickly. These were worked out by guidance and trajectory gurus working at MSC.

Uploaded a much better resolution of my previous PGNS star chart post. Posting the star list again, the chart and navigation stars are a really helpful tool in memorizing the night sky, renewed purpose for an old Apollo G&N supplement.
