As usual I would first consult the manual ;)
\Orbitersdk\doc\orbiter_lua.chm

"Vessel position" is a bit tricky to answer without knowing what exactly you would like to achieve.
For an "orbital" position something like this would do the job:
SQL:
v:set_elements ({a=4000e3, e=0, i=0, theta=0, omegab=0, L=0}, {href=oapi.get_objhandle('moon'), mjd_ref=0, frame='equ'})
With the first table being of type ELEMENTS:
  • a semi-major axis [m]
  • e eccentricity
  • i inclination [rad]
  • theta longitude of ascending node [rad]
  • omegab longitude of ascending node [rad]
  • L mean longitude at epoch [rad]
I have no example for a position on the surface of a body, but I guess there is at least one (Lua-)function or forum-member that can help ;)
