Please check a source that looks funny
editThe "From Engineering To Big Science" source (currently #5) looks funny / off because it has a long segment written with it. Is this meant to be in the article? Would other editors please check this? Astrolabe 150c (talk) 00:08, 15 January 2024 (UTC)

- Lead
- Seems fine. The "as of April 2024" may be updated with the current numbers, but there's a hidden note of not doing so more than once a month, so I didn't touch anything. Is the idea to update it only when updating the month, to do it at some certain day, or some other precise system?
- There was a discussion regarding the updation and a consensus was reached for the same. As of now, there is no certain date that is fixed for updation, but it is only for a reference point. The Herald (Benison) (talk) 04:43, 9 June 2024 (UTC)

- File:Voyager Program - RTG diagram 1.png - The PDF can't be accessed, and the site hosting it (planetary.s3.amazonws.com) does not have NASA in the name. Worse, when googling it the results are not about astronomy, and there are even some malware report pages.

On a general overview, the article has way too many images. Try to be a bit more selective.
- Yes, I agree. But given the nature of the project, I think the images enhance encyclopedic value of the article. If you don't agree, will a 5 image per section max criteria work? The Herald (Benison) (talk) 06:16, 9 June 2024 (UTC)
- Update: I have trimmed down the number of images in various sections. The Herald (Benison) (talk) 08:53, 9 June 2024 (UTC)
- History
- You should link to Syzygy (astronomy), a planetary alignment.
- Saturn has many moons. Why was the study of Titan so important that they even considered sending both Voyagers there?
- Why link "The Earth" instead of just "Earth"?
- "Scientific instruments" has an unresolved maintenance tag
- Done. Added a couple of sentence on Titan's importance and fixed the tag.
- Mission profile
- Section is only a pair of giant images and a table, with no text.
- It was a section mistake. Mission profile is a level 2 heading and the following sub sections are level 3. The tables and images are summaries for the entire mission profile. Fixed.
- Launch and trajectory
- First paragraph has no references
- File:Voyager 2 path.svg is unreadable at article size
- File:Voyager 2 velocity vs distance from sun.svg, the first sentence is enough. The second is clarification and can go in a note, to reduce bloating.
- Is it appropriate to place the images in the middle of the text? Why not at the end of the subsections, as below?
- The second paragraph is only one line and a half long, and half of it is about Voyager 1.
- "a complication arose" is a bit redundant, just explain directly what happened.
- The paragraph ends with no reference
- Done. In the second paragraph, it is a comparison of intial orbits of both the spacecrafts, which caused the differences in the arrival time and hence, subsequent changes in the mission profile. They are mentioned in the sub sections ahead.
- Encounter with Jupiter
- Exploration of Jupiter is about all explorations of Jupiter, not just the Voyager 2. Use {{See also}} or {{Further}}, not {{Main}}.
- The article is already using way too many images, but this is a bit over the top. 8 images below and 2 to the sides, 10 images in a section!
- Link to Volcanism on Io
- Fixed. Took out some images, since they are explained in Voyager program.
- Encounter with Saturn
- Again, "Exploration of..." is not a proper main article
- Again, way too many images.
- There are photos of Enceladus, Tethys, Titan, Iapetus, but not a single word about what did Voyager 2 saw when they were studied.
- Fixed. Removed extra images since they are described in the program article. Not needed here, IMO. Added info about Titan flyby.
- Encounter with Uranus
- Again, "Exploration of..." is not a proper main article
- Given the discussion about Uranus' axis, a link to Uranus#Axial_tilt may be appropriate.
- Unlink "hypothesis", just a common word.
- Done.
- Encounter with Neptune
- Again, "Exploration of..." is not a proper main article
- Link Rings of Neptune
- Done
- Interstellar mission
- "In 1992, Voyager 2 observed the nova V1974 Cygni in the far-ultraviolet." Single-sentence paragraph. Nothing to add to it?
- There is an unresolved "As of?" tag
- 7th paragraph has no references
- First they announce that Voyager 2 would reach interstellar space in 2016, and then report it in 2018. Was it a delay, or did they incorrectly measured the distances and speeds involved?
- "As a failsafe measure, the probe is also programmed to autonomously reset its orientation to point towards Earth, which would have occurred by October 15." No reference
- Done. Removed the uncited sections because I couldn't see the relevance of it. The 7th paragraph was removed because the data was old and there's no point describing the 2012 distances now, along with the comparison of Voyager 1. The delay was to reach a consensus on the sensor readings. I have added a few more details onto the paragraph.
- Reductions in capabilities
- Many entries in the table are not referenced.
- We're in 2024. 2016 and 2020 are in the past, so "approx" is not appropriate. If those things happened in those years, remove it. If the happened in another year or not yet, fix it.
- "The probe is expected to keep transmitting weak radio messages until at least the mid-2020s, more than 48 years after it was launched." Does NASA have further plans for Voyager when that moment comes, or will it be completely on its own from then on?
- The planned turning off in 2016 and 2020 was never carried out as no record exists. So I have removed them. Added references and expanded future of the probe.
- Golden record
- Linked.

- @Cambalachero: thanks for the review. Apologies for the delay in response, but I have addressed the points and please have a look at the updated version. Thanks and happy editing. The Herald (Benison) (talk) 08:53, 9 June 2024 (UTC)
@Cambalachero: it looks like The Herald has finished responding to your comments. Are there any other aspects that need to be addressed before the review is completed? Fritzmann (message me) 10:20, 16 June 2024 (UTC)

- ... that Voyager 2 has been transmitting data for over 46 years, making it the longest active space probe in history?

- Article recently updated to GA status. Very detailed and intricate with extensive uses of images and other detailed graphs. Article is cited well with no problems regaridng copryright issues. Good to go. - Toadboy123 (talk) 18:56, 17 June 2024 (UTC)
- @Thriley, Toadboy123, and The Herald: Unless I am mistaken, I find the hook sentence in the article but it is not cited. Per our WP:DYKCRIT
The hook fact should be cited in the article, no later than the end of the sentence it appears in.
Bruxton (talk) 18:48, 21 June 2024 (UTC)- @The Herald: Can you get the citation of the hook done? Toadboy123 (talk) 18:52, 21 June 2024 (UTC)
