NASSP uses a mission file to specify vehicle configuration and mission parameters.

Option Function Default Value
SMJCVersion Service Module Jettison Controller version. A modification was used on Apollo 13 and later to prevent the Service Module from skipping out of the atmosphere on reentry. Valid values are:

1 Block I and pre Apollo 13
2 Apollo 13 and later

1
JMission If set to TRUE, the CSM will have the panels and systems that were flown on the J-type Apollo missions FALSE
Panel277Version Version of CSM panel 277. Valid values are:

0 No panel
1 J-type mission panel
2 Skylab missions panel

0
Panel278Version Version of CSM panel 278. Valid values are:

1 Pre Apollo 15
2 Apollo 15-16
3 Apollo 17
4 Skylab
5 ASTP

1
LMDSKYVersion Version of the LM DSKY. Valid values are:

1 Same as CM DSKY (Apollo 10 and before)
2 ALT and VEL lights (Apollo 11-14)
3 PRIO DISP and NO DAP lights (Apollo 15-17)

2
HasLMProgramer If set to TRUE the Lunar Module Programer for automatic flight and remote control is used (Apollo 5 only) FALSE
HasAEA If set to TRUE the Lunar Module has an Abort Electronics Assembly (computer of the AGS). Only Apollo 5 did not fly one. TRUE
LMHasAscEngArmAssy If set to TRUE the Ascent Engine Arming Assembly is used to remotely fire the APS engine in an unmanned configuration (flown on Apollo 9 and 10). FALSE
LMHasLegs If set to TRUE then the LM has legs. TRUE
LMHasDeflectors If set to TRUE then the LM has RCS plume deflectors. TRUE
LMHasCask If set to TRUE then the LM has a RTG Cask. TRUE
CSMHasHGA If set to TRUE then the CSM has an S-Band High Gain Antenna. TRUE
CSMHasVHFRanging If set to TRUE then the CSM has the VHF Ranging System. TRUE
CMCVersion Name of the CMC software. Artemis072
TEPHEM0 If Skylark or a custom CMC rope is used for the mission, this value is used to initialize the CMC clock on initial startup. It is the MJD at midnight July 1st preceeding the launch. 41133.0
LGCVersion Name of the LGC software. Luminary210
AEAVersion Name of the AEA software. FP8
InvertLMStageBit Input bit to the LGC software for the current stage (descent stage attached or not) is inverted. This was the case on Apollo 5 (LM-1) FALSE
ATCA_PRM_Factor A factor used in the LM ATCA to control the linearity of the ACA inputs for rotational control by the astronauts. Apollo 9 used 0.1 which was determined to be too sensitive, so that it got changed to 0.3 afterwards 0.3
LM_CGX_Coefficients Polynomial coefficients for the LM ascent stage center-of-gravity X-component as a function of total mass. 8.7719e-08, -7.9329e-04, 7.9773e+00
LM_CGY_Coefficients Polynomial coefficients for the LM ascent stage center-of-gravity Y-component as a function of total mass. 2.1488e-10, -2.5485e-06, 1.2769e-02
LM_CGZ_Coefficients Polynomial coefficients for the LM ascent stage center-of-gravity Z-component as a function of total mass. 6.1788e-09, -6.9019e-05, 2.5186e-01
CMtoLMPowerConnectionVersion CM to LM power connection version. 0 = connection doesn't work with LM staged, 1 = LM has a CB to bypass circuit to descent stage, 2 = circuit bypassed automatically at staging. 0

TBD
