Gravity of Mars
[edit]

- ... that many Martian basins (gravity map of Mars illustrated) have a negative free air gravity anomaly? Source: "You are strongly encouraged to quote the source text supporting each hook" (and [link] the source, or cite it briefly without using citation templates)
- ALT1:... that the gravity of Mars shows that the thickness of the crust is most often 32 or 58 km? (graph of thickness pictured) Source: "You are strongly encouraged to quote the source text supporting each hook" (and [link] the source, or cite it briefly without using citation templates)

Moved to mainspace by Xaviertang (talk). Nominated by Graeme Bartlett (talk) at 05:11, 18 November 2017 (UTC).
This is an incredible article and insightful article. @Xaviertang: has most certainly proven his dedication to the subject at hand. I'm sure some users may be able to point out a minor flaw with the article here or there, but I cannot see any major problems that would prevent this from being approved for Did you know...?. I would suggest a better hook, though. Evidently, the main nominated hook is definitely more interesting than the alternate proposal in my opinion, though it can definitely be worded better.
- Firstly the way the wikilink is presented is weird. One would expect "Martian basins" would link to an article about basins on Mars. It would make more sense if the wikilink was wrapped with a text that directly refers to the "Gravity of Mars". Secondly, the parentheses phrase to denote an illustrated subject is way too long for a Did you know...? section. Thirdly, the caption for the image is too long as well. Normally image captions rarely go into any detail other than the strict subject of the image. You'll find many examples of this in recent additions to the Did you know...? section. My proposals are:
- ALT2:... that Mars' gravity (illustrated) is affected by many negative free air gravity anomalies on its surface?
- Image caption: Gravity map of Mars unsigned by user talk:PhilipTerryGraham
- I am happy with that ALT2. But we still need an itemised review to pass DYK! Graeme Bartlett (talk) 12:05, 22 November 2017 (UTC)
Full review still needed on the actual DYK criteria. BlueMoonset (talk) 16:56, 3 December 2017 (UTC)
- This is almost ready: article was nominated within the required timeframe. Length requirements have been met. Hooks are interesting, particularly ALT2 (which I prefer). Article is stable, and image uses are proper (free license and fair use). Article is mostly sourced to journals, some of which are offline or paywalled, so hooks are accepted good faith. No QPQ is necessary for the creator; the nominator has provided a QPQ. However, there are still two issues with the article: the lead has some grammatical errors (like how "Study of surface gravity of Mars provides beneficial information for current mapping and future landing project." should be "The study of surface gravity of Mars provides beneficial information for current mapping and future landing projects.". In addition, the lead feels inadequate and doesn't really adequately summarize the contents of the article. Some statements in the article, like "subsequent gravity models are developed from the radio tracking data." and "Combination of Doppler shift and range observation promotes higher tracking accuracy of the spacecraft." lack footnotes. Other ending sentences read awkwardly (like "Otherwise, it would result in considerable errors.") and may need to be rewritten. Once these issues are fixed this should be good to go. As an astronomy buff myself, this is an interesting article that would make a great DYK hook; I would even request that it be the picture hook if it goes up.

- I have fixed the three sentences highlighted. Expanind the lead will await tomorrow, as will the referencing, though I suspect reference :4 is the one. Graeme Bartlett (talk) 11:46, 9 December 2017 (UTC)
- The requested fixed have been done. There is only one typo left in the article: "Average gravitational acceleration on Mars" is missing a "the" before "average", but other than that, I'm not seeing anymore problems with the article. This is good to go.
