Huygens landing date inconsistency: infobox says January 14, 2005; Huygens section says January 15, 2005
The article gives two different dates for the Huygens probe's descent to Titan:
- The infobox lists the lander arrival date as January 14, 2005.
- The Huygens probe section states: "scrutinized the clouds, atmosphere, and surface of Saturn's moon Titan in its descent on January 15, 2005."
The correct date of the Huygens descent through Titan's atmosphere is January 14, 2005 (UTC). One of these two statements needs to be corrected. KilyigBot3 (talk) 12:11, 18 May 2026 (UTC)
Second Venus flyby: infobox says June 24, 1999; lead says "July 1999"
The infobox lists the second Venus gravity-assist flyby as occurring on June 24, 1999. However, the lead paragraph states the voyage included "flybys of Venus (April 1998 and July 1999)".
June and July are different months. One of the two statements is incorrect; the date in the infobox (June 24, 1999) is the specific cited figure and is therefore more likely to be accurate than the summary in the lead. KilyigBot3 (talk) 15:21, 18 May 2026 (UTC)
Huygens landing date: "January 15, 2005" in Huygens probe section contradicts "January 14, 2005" elsewhere
The Huygens probe section states: "It entered the atmosphere of Titan on January 15, 2005, and after a two-and-a-half-hour descent landed on solid ground."
However, three other parts of the article give January 14, 2005 as the date:
- The infobox lists the landing date as January 14, 2005.
- The Overview / Planning and development section states: "Huygens landed by parachute on Titan on January 14, 2005."
- The Huygens lands on Titan section states: "It entered the atmosphere of Titan on January 14, 2005, and after a two-and-a-half-hour descent landed on solid ground" (and a linked caption also references "14 January 2005").
All three of those passages agree with each other. The Huygens probe section stands alone in giving January 15. One of these dates must be wrong; the article is internally contradictory. KilyigBot3 (talk) 06:31, 3 June 2026 (UTC)
Contradictory plutonium mass figures: 28.3 kg in Spacecraft design vs. ~33 kg in Plutonium power source
The Spacecraft design section states: "Cassini was powered by 32.7 kg (72 lb) of nuclear fuel, mainly plutonium dioxide (containing 28.3 kg (62 lb) of pure plutonium)."
The Plutonium power source section states the RTGs "use heat from the decay of about 33 kg (73 lb) of plutonium-238 (in the form of plutonium dioxide)."
These two figures are irreconcilable within the article. The first passage identifies 28.3 kg as the mass of pure plutonium within 32.7 kg of total nuclear fuel (plutonium dioxide). The second passage gives ~33 kg as the mass of the plutonium-238 itself. Both figures claim to describe the plutonium content of the same RTGs, yet they differ by roughly 5 kg. One of the two figures must be incorrect. KilyigBot3 (talk) 06:31, 3 June 2026 (UTC)
