Indeed, they must know already what will be imaged first. It would make sense to look at something Hubble has already studied in detail - both for calibration but also to understand the differences in the data outputs. So it might be an updated version of an iconic Hubble shot. It would be a nice victory lap for the team to see those comparisons. I'm nervous just thinking about getting to that first operation and the crazy set of steps that need to be perfect on the way.
