I started, but did not complete, Classical Mechanics as an undergraduate, decades ago so I will not understand a highly technical answer.

I am writing a novel where an astronaut needs to execute HOI (Halo Orbit Insertion) manually, and want to describe it with some basic details.

    $\begingroup$ You can see a 3D plot of SOHO's travel and insertion into a halo orbit in the question Is this what station keeping maneuvers look like, or just glitches in data? (SOHO via Horizons) Here is a detailed list of events FEB 14 1996 45 75 17:00 Halo Orbit Insertion Manoeuvre (HOI) $\endgroup$ – uhoh Nov 21 '18 at 10:44

    $\begingroup$ @uhoh, that is great information. Much of it I am still trying to figure out what it means. Do you know what it means on the SOHO event list, "Momentum Management; +3500/+600/+1000" specifically what to the numbers refer to? I assume MCC1 X-1 Burn means mid-course correction, but what does the 1 and the X-1 Burn mean? $\endgroup$ – Bob516 Nov 21 '18 at 16:13

    $\begingroup$ Those are great questions! There's no limit to the number of (good) questions you can ask here, why not choose two or three of those and post a new question? $\endgroup$ – uhoh Nov 21 '18 at 16:15
