There are several reports in the news that the Juno spacecraft executed a very long propulsive maneuver so that it wouldn't pass through Jupiter's shadow. Apparently it would be in dark so long that the batteries would die before it returned to sunlight, and that was considered somewhere between risky and fatal.

Last time I checked which is about two years ago, Juno was in a highly elliptical, near-polar orbit.

So how did this maneuver allow Juno to avoid Jupiter's shadow (presumably at apoapsis?) Was it basically a plane-change, rotating the vertical orbital plane from one side of the shadow to the other, or was it something more interesting?

Either way, if it's possible say "by how much" the orbit was changed in some way, that would be good to know.

    $\begingroup$ The image in that article appears to imply that the orbit is still polar, which should indeed imply a plane change. But I'm not confident without actual data or statements. $\endgroup$ – Hohmannfan Oct 3 '19 at 10:39

    $\begingroup$ Alternately it could have changed the eccentricity, changing the orbital period, and so missing it that way, but the plane change is far more likley $\endgroup$ – JCRM Oct 3 '19 at 15:57
