Rationale for image replacement

I noticed that this image was replaced with a version that is less detailed. In my opinion, that image should have a separate filename and this image should retain its original content. There is no other place on the wiki that contains this information. What is the rationale for replacing the image with a version that is less informative? --Stux (talk) 14:54, 26 December 2021 (UTC)

@Stux: The new image was uploaded from the same page as the previous image, which means the image was updated by NASA. The previous version was uploaded in 2017. There is a concern that the description of the previous image was incorrect. So I think NASA decided to remove the detailed descriptions instead of updating them. We should not keep the image if it contains incorrect information.―― Phoenix7777 (talk) 20:44, 26 December 2021 (UTC)

@Phoenix7777 I find inappropriate to upload an image and replace the present one so that it changes in all wiki languages, believing that the other stages of Webb could change . You want a right image ? Upload another image and use that image with other name. (Usually it's the right way). Hi. ☼ Windino ☼ (Rec) 19:20, 27 December 2021 (UTC)

Thanks @Phoenix7777 for linking to that discussion. I was certainly not aware of that. (Perhaps linking to it from the description might be useful.)

@Windino: unfortunately it doesn't seem like NASA has provided a corrected version of the image and instead opted to publish the less detailed one. A new image with the correct information would have to be made using an image editor of some kind. I also don't know where the official (and correct, and detailed) timeline information is published. Links to that would also be helpful and can be added to the description. The current link only has a vague timetable. --Stux (talk) 23:15, 27 December 2021 (UTC)

@Stux: The image was updated between June 19 and Jun 29. See following archived pages.―― Phoenix7777 (talk) 00:04, 28 December 2021 (UTC)

• Old image on June 19:[1]
• Updated image on June 29:[2]

Thanks @Phoenix7777: I was actually looking for a page that would contain the same information as the old image but in text form and updated regularly. While checking out the NASA blog, I found these two entries: 1 and 2 that talk about planned mid-course corrections. The first page has this line:

After this burn, no key milestones are time critical, so the order, location, timing, and duration of deployments may change.

This makes it clear that the reason for the vagueness in the timetable is that NASA is allowing for changes in its timetable and chose not to commit to a specific and rigidly timed sequence of events. --Stux (talk) 00:56, 28 December 2021 (UTC)

More detailed deployment information (close to what I was looking for) can be found in these two pages:

• https://jwst.nasa.gov/content/webbLaunch/whereIsWebb.html
• https://jwst.nasa.gov/content/webbLaunch/deploymentExplorer.html

@Stux and @Phoenix7777 Exactly ! The timeline was (is) orientative. Planified but not automatic. The commands must be send by Earth. Every deployment could be anti-posticipated due to...reasons. Also for this that in wikidata the launch-date of missions are not placed. (delayed, delayed, delayed) I uploaded the foto with the description timeline indicative, not exactly. This is the question about Nasa. Still, there'a wikipedia question: is someone upload a photo (linking that on a page), is not a good behavior that another user substitute that foto linked by other user in other page with the reason that the photo is not exactly corrispondent, unless the photo is improved. My purpose is to change the detailed photo with Adobe, stage by stage. But please, be patient. (sorry for my english) ☼ Windino ☼ (Rec) 07:08, 28 December 2021 (UTC)

Hi friends :) I've uploaded a new version with the correct time (I've been generic indicating 1 day). Tell me what you think about the future of the image and it's caption. I'll take care of the Webb's stages; In my wikipedia language i'll write timeline approssimative set up by NASA (something like that). --☼ Windino ☼ (Rec) 17:06, 28 December 2021 (UTC)

--Solarmcpanel (talk) 19:30, 6 January 2022 (UTC) Hi: I believe the image is not correct, it has the primary mirror unfolding before the secondary mirror. I don't think I'm clever enough to correct this myself!

Yes. Stages were approximated by NASA years ago. It's not a good idea to changes the pict side by side. (WP:NO-NEWS). Later i'll (or someone if want to do) correct the various steps. ☼ Windino ☼ (Rec) 19:46, 6 January 2022 (UTC)
