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?

• 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.

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

Mission profile

• Section is only a pair of giant images and a table, with no text.

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

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

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.

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.

Encounter with Neptune

• Again, "Exploration of..." is not a proper main article
• Link Rings of Neptune
