From the scripting API:
enum eScriptTransportItems
{
kTransNothing = 0, //kNothing
kTransGornEgg,
kTransSpareParts,
kTransCaptain,
kTransBlueStar,
kTransDilithiumCrystals,
kTransGravTank,
kTransMarineDude,
kTransHarryMudd,
kTransInfiltrator,
kTransNovaMine,
kTransRomulanAle,
kTransTribbles,
kTransAlienArtifact,
kTransCaptainDude,
kTransWeaponSchematic,
kTransMedicalSupplies,
kTransAwayTeamItem,
kTransDiplomat,
kTransInjuredDude,
kTransMedicineJar,
kTransScientists,
kTransLifePodDude,
kTransDeathPlague,
kTransBlackBox,
kTransPsionicDisruptor,
kTransIonicProjector,
kTransEngineers,
kTransPrisoner,
};
Though I doubt all of them are in existing dynaverse missions.
