-    - work on maneuver interpolation. see docs/planning/hohmann-rendezvous-quantization-fix.md
-    - simulation propagation refactor: see docs/planning/propagation_refactor.md
-        - need to make, and possibly save in scripts/, a separate propagation
-            simulation to generate pre-computed values we can use in test cases
-        - debug maneuver at periapsis (fixed?)
     - interplanetary transfers
     - SOI boundary testing
         - draw SOI boundry in graphical sim

     - actually, we should start out simpler. create and test maneuvers in planetary
         frame before starting on interplanetary patched conics, oops
         - will still need hohmann transfers, circularizing, plane change, etc.
-    - something is not working with hohmann transfers, maybe SOI/parent logic?
-    - orbital rendezveuz
     - interplanetary/SOI changing transfers
     - remove bodies on non closed orbits after they are a certain distance from
         the root body, or bary-center
