There is a long list of scientists that know exactly what research they are doing on JWST down to the minute [0]
For example, Dr Christine Chen et al will be using JWST for at least 34.9 hours to study the Icy Kuiper Belts in Exoplanetary Systems using near infrared spectroscopy [1]
Yeah, I read that, just not impressed by minor projects with low outcome. It roughly equal to routine PhD-tier experiments done on the accelerator at some provincial lab.
Just look at breakthrough chances from, for example, 5 days trans-neptunian object search or the pointing of instrument at largely unexplored Uranus system for petty 30 hours.
This sort of proves my point, no one knows which exactly research JWST will do upon deployment, because original mission goals mainly became obsolete.
