Hello, I am trying to compile the DeltaGlider source code in Visual Studio 2017, but I keep getting the following two errors: Severity Code Description Project File Line Suppression State Error MSB6006 "cmd.exe" exited with code 255. DeltaGlider C:\Program Files (x86)\Microsoft Visual...

Hello, I am currently studying the lemsystems.cpp file, and I came across the following two lines in the void LEM::SystemsInternalTimestep(double simdt) function (lines 1331 and 1332): double mintFactor = __max(simdt / 20.0, 0.02); double tFactor = __min(mintFactor, simdt); I'm not entirely...

Hello, I'm doing an Apollo 11 mission, and I have just been informed that MCC-4 has been scrubbed. It then asks me to prepare for a data uplink by turning on the various UPLINK TLM buttons. I set all of that up, and press the "Ready for Uplink" button, but then, all it says is: "CSM state...

Hello, I have been working through an Apollo 11 simulation, and I notice that one of the switches that I constantly need to press is the Manual Attitude switches. The problem is, I have no idea what they do! I've tried looking in AOH Vol 1, but it's very cryptic, and doesn't really help me...

I am currently studying "The Apollo Guidance Computer: Architecture and Operation" by Frank O'Brien, and I'm having some trouble with the section on memory addressing. On page 61, under the heading "Fixed storage banking," it says the following: "One value has already been mentioned: a binary...

I've started Apollo 11 again from the beginning, and everything was going well until MCC-1. MCC progresses successfully from State 24 to State 25 Substate 2, but it doesn't seem to get any further, it just sits there. I therefore never find out whether MCC-1 is go or scrubbed. A few days ago I...

Hello, I'm just wondering, what is meant on the MFD checklist when the item has (Decal) next to it? I'm connecting the LM to CSM power at the moment, and I've just been skipping the Decal steps, but then the Sys Test 4D gives me 0 volts. I guess this is supposed to be the CSM/LM umbilical...

Hello, I'm about 7 hours into an Apollo 11 mission, and for some reason MCC isn't uplinking state vectors to me. I set all the required switches to UP TLM, etc. and I say "Ready for uplink" in the MCC menu. It then says: Ready for Uplink CSM State Vector and then nothing happens. No lights...

About 10 years ago, it looks like a copy of the AOH Vol 2 for the CSM was scanned and made available here: http://forum.nasaspaceflight.com/index.php?topic=15413.0. As far as I can tell all of the links are now broken, and I've had no luck searching online for the handbook. Can anyone here...

Hello, I've primarily been using NASSP on my laptop, but I recently set it up on my desktop, which is far more powerful. However, when I run the Apollo 8 mission from launch, the frame rate is substantially lower on the desktop PC. On the desktop, the frame rate maxes out at about 15 fps, with...
