Useful links and details
Moving Targets Observatory Tracking Non-sidereal tracking Implemented, testing underway Rates up to 30 mas/s (108 /hr) supported (max rate of Mars) Modeling shows excellent pointing stability (< 7mas NEA), ~same as fixed targs The moving-target is fixed in detector frame while exposing Dithers, mosaics supported (slightly higher overheads) ~1 mag brighter guide stars required for moving targets Pointing jitter is predicted to be comparable to that for fixed targets Is small enough not to degrade spatial resolution 15
JWST can Track Nearly All Targets JWST can track nearly any targets within its field of regard on any given day even NEOs and Comets. 10/15/2017 JWST Moving Targets - J. Stansberry - DPS Meeting 2017 16
