Once a trajectory is propagated (Spacecraft or Rocket), it is often useful to write a SPICE SPK (.bsp) kernel from the ephemeris data to be able to plug into other software programs. Specifically, NASA's SPICE-Enhanced Cosmographia reads in SPICE kernels for its animations, which are used in the YouTube videos associated with this repository.
