Ephemeris Plot

Ephemeris Plot fetches one spacecraft's Carrington-frame trajectory and plots it as points -- hourly (r, t, p) positions from JPL Horizons, cached locally so repeat evaluations do not re-fetch the same window.

The Spacecraft node's spacecraft CHOICE selects which archive to query (psp here); its own t0/t1 set the ISO 8601 date window, and Spacecraft Read's sc port is wired to the Spacecraft node's ephemeris dot to pull the trajectory itself.

Change spacecraft to any other key -- earth, stereoa, solo, and many more -- and adjust t0/t1 to a window that spacecraft actually has data for.
