Similar question was just asked during press conference and the answer was "telescope is cooling a bit faster than we simulated but it is not a significant difference, it might be ready one or two days ahead of current estimation".
Current timeline is for getting all 4 cameras to work, but I think only one needs cryogenic cooling, other 3 could work with just sunshield. In another answer one of the engineers said that first images will be released once telescope is fully operational (aka all 4 instruments cooled down).
- max-ibel 5y agoSurely, it can take pics during this time with suboptimal cooling. Probably hard to resist the temptation:) There might be good engineering reasons to experiment early, like testing comms systems etc
- terramex 5y agoIt will surely take plenty of engineering and calibration photos during that time. I don't think they will be published instantly because telescope operators want to make a 'wow' effect with first photos from JWST. Here is first technical image from Hubble, before its mirror's flaw was discovered: https://stsci-opo.org/STScI-01EVTBEME0059ASGX8X3DFWZMX.jpg https://stsci-opo.org/STScI-01EVTBEME0059ASGX8X3DFWZMX.jpg
