Hi,Interesting.
It's heading slightly (or even not so slightly) off L2.
There are scenarios with L2 (the data is from Horizons System too):
Yes, mayby.I have a hunch those predicted state vectors don't include the two MCC's that have been made already, and that JPL Horizons has been updated since then to include them, but possibly not future MCC's. Not sure. I just grabbed the vectors for MJD59606 (27 Jan 2022) and I have different numbers.
TRAJECTORY
MCC1A (65-minute engine burn) began 2021-Dec-26 12:50 UTC, completed 01:55 UTC.
MCC1B (09:27 engine burn) began 2021-Dec-28 12:20 UTC, completed 12:29:27 UTC.
Post-launch trajectory from Goddard Flight Dynamics Facility (FDF), based on
data through ~20:00 UTC Dec 30, predicts thereafter.
