I knew Sojourner uses solar power. [It should've had a (ReChargable) battery.] It should be useful as a plant-carrier. That way we can replace CO2 with Oxygen... Photosynthesis! As long as the rover goes from east to west, and a Mars explorer keeps watering the plant, it will survive with everything it needs to make its own food. --Brainiac Amin (talk) 12:31, 3 December 2013 (UTC)Brainiac AminReply[reply]

Hi Nikkimaria (talk · contribs)! Is Screen Rant appears to be reliable so the fact that the rover was in the TBBT could stay in the article? [1] And I don't really see why is it a problem - it's not some controversial subject, it's in the episode, and everybody can check it simply by watching it. Artem.G (talk) 05:48, 12 August 2021 (UTC)Reply[reply]

Hi Artem.G, this RfC concluded that a source proving only that such a reference exists is not sufficient for inclusion - we need a reliable secondary source demonstrating its significance to the article topic. As to the source you propose, as per WP:RSP it is considered marginal. Nikkimaria (talk) 11:53, 12 August 2021 (UTC)Reply[reply]

Thanks! I was not aware that such list of sources exists. But, in your opinion, is this source enough to include TBBT to this article? I'm not completely ok with any entries to "In Popular Culture" sections, because, f.e. Robot Hall of Fame is in the article, though there were millions more viewers of the TBBT series than people who know that this Hall of Fame exists. So in this case I'm not sure, these series were popular and the rover was indeed mentioned, but how should the importance of it be measured? Artem.G (talk) 15:02, 12 August 2021 (UTC)Reply[reply]

I happen to think the RHoF sourcing also needs improvement, but in broader terms: the theory from that RfC was that if a mention of the subject is truly significant, there would be sourcing demonstrating that. Imagine for example as a gold standard a high-quality source saying "Most people recognize the rover because it was featured in this TBBT episode" or something to that effect. The Screenrant source demonstrates that the mention exists; I'm not sure it demonstrates significance. Nikkimaria (talk) 21:12, 12 August 2021 (UTC)Reply[reply]

It's reasonable, thanks! But again, is there any source saying "Most people recognize Sojourner because it was included into Robot Hall of Fame"? (I have no problem with it, I just think that it is a good example). So significance is still relative, though I understand what you mean. Artem.G (talk) 05:48, 13 August 2021 (UTC)Reply[reply]

I will ocassionally put some links here that may be used later in the article. Artem.G (talk) 10:01, 14 August 2021 (UTC)Reply[reply]

Hi Diannaa (talk · contribs)! Thanks for adding PD notice, I wasn't aware of this. But the link you've added "Mars Pathfinder PIP (Continued - Part 2/3)" seems to be dead with no archived version. So maybe the previous ref would be ok? Can you please share where did you find it? Artem.G (talk) 14:39, 20 August 2021 (UTC)Reply[reply]

I'm having no problems accessing it. Rotideypoc41352 (talk · contribs) 14:41, 20 August 2021 (UTC)Reply[reply]

I've checked it under the US VPN and it works! Sorry for that and thanks for the source :) Artem.G (talk) 14:46, 20 August 2021 (UTC)Reply[reply]

Because you mentioned the lack of an archive link, I had Internet Archive create one and added it to the ref. Rotideypoc41352 (talk · contribs) 14:52, 20 August 2021 (UTC)Reply[reply]

Thanks a lot! It was just strange to me that NASA's page can be opened only with US IP address, it never happened before. Artem.G (talk) 15:07, 20 August 2021 (UTC)Reply[reply]

Both http and https versions of the url work fine for me also. Thanks for adding the archive url, that's a good idea regardless.— Diannaa (talk) 18:51, 20 August 2021 (UTC)Reply[reply]

Content feedback

Tone

• Some sentences should be more neutral.
  • Maybe you can point me to the problematic sentences? Artem.G (talk) 17:27, 13 September 2021 (UTC)Reply[reply]
    • Actually, nevermind, there's nothing wrong with the tone. My bad CactiStaccingCrane (talk)

Formatting & styling

• Adding small text for credits to rover designers is not in line with Wikipedia's manual of style. You might want to merge it to prose.
  • I will think about it, it seems that I saw it in some GA about a spacecraft. Artem.G (talk) 17:27, 13 September 2021 (UTC)Reply[reply]
  • I've created 'Key personnel' section, so it's Y. Artem.G (talk) 10:04, 1 October 2021 (UTC)Reply[reply]
• Coordinates of landing should be replaced by name of relative location in Mars.
  • Y
• Some lone-sentences should be merged to paragraphs.
  • I'll check it.
    • mostly Y, if you think I've missed smth, please point me to it. Artem.G (talk) 10:04, 1 October 2021 (UTC)Reply[reply]
• Elements names don't need to be labeled with it's element symbol. This problem is fixed by me, Cacti. Y
• Some grammar mistakes are seen, although most of them are very minor. Some of the typo is fixed by me, Cacti.
  • Thanks for that! Artem.G (talk) 17:27, 13 September 2021 (UTC)Reply[reply]

Other than that, the article is very well done! Great job! CactiStaccingCrane (talk) 07:58, 13 September 2021 (UTC)Reply[reply]

Thanks for your review! I am mostly offline till the end of the month, but I will definitely address all the points you mentioned. I'll ping you when everything will be resolved. Artem.G (talk) 17:27, 13 September 2021 (UTC)Reply[reply]

• CactiStaccingCrane (talk · contribs), I think that everything is done, please look through it when you have time. Artem.G (talk) 10:04, 1 October 2021 (UTC)Reply[reply]

    @Artem.G Here you go, I have edited the article to show the icon and the wikiproject assessment. CactiStaccingCrane (talk) 10:20, 1 October 2021 (UTC)Reply[reply]

    • Thanks a lot, it was my first attempt of writing a GA, and it took a lot of time :) Artem.G (talk) 10:41, 1 October 2021 (UTC)Reply[reply]

      • • Well, I think you should aim for the next big thing, which is . It is the highest article class you can achieve. Here's the page about it: Wikipedia:Featured articles.

Sojourner rover on Mars

• ... that the first successful Mars rover, Sojourner (pictured), was named after a Civil-War-era African-American abolitionist and women's rights advocate Sojourner Truth? Source: "Valerie Ambroise, 12, of Bridgeport, CT, submitted the winning essay about Sojourner Truth, an African-American reformist who lived during the Civil War era."

Improved to Good Article status by Artem.G (talk). Self-nominated at 05:46, 7 October 2021 (UTC).Reply[reply]

• GA:DYK nomination:  Hook is interesting and within prescribed limits, and is well sourced. Images are in the public domain or are from the U.S.gov (NASA), However, there is one image that is 'fair use', which is not allowed in DYK nominations, per DYK criteria. -- Gwillhickers (talk) 19:06, 16 October 2021 (UTC)Reply[reply]

• Thanks for the review! I'm new to DYK process, but the rules say "Pictures and videos used in all DYK articles should be suitably licensed: PD, GFDL, CC, etc., including fair use where appropriately applied." (WP:DYKIMG). As that image wouldn't be on the main page, isn't it ok to have a fair use image in the article? Artem.G (talk) 20:09, 16 October 2021 (UTC)Reply[reply]

• When you click on the edit tab of your (or any) DYK template, listed under Other, it says no fair use allowed. Yes, fair use images are not allowed on the main page, which applies to all fair use images used in any article. We could consult a third opinion if you like, or we could simply remove the image for the time being, and return it to the article after the article has been listed on the front page. If you decide to temporarily remove the fair use image the article will be unquestionably good to go. Your call. -- Gwillhickers (talk) 20:26, 16 October 2021 (UTC)Reply[reply]

I think you're misinterpeting the rules here Gwillhickers. The only prohibition is that fair use images cannot be used as the hook image for hooks (i.e. we can't use the picture from The Martian to accompany the hook, though the current image is fine). I don't think there's anything in the rules which prohibit fair use images from being used at all in articles featured on DYK; if that were the case, there'd be a ton of ineligible articles, including pretty much any article on notable characters or episodes. Narutolovehinata5 (talk · contributions) 08:15, 17 October 2021 (UTC)Reply[reply]

Looking at the notice again, I think the "be free (no fair use)" message is definitely referring to hook pictures, not pictures on DYK articles in general. Narutolovehinata5 (talk · contributions) 08:16, 17 October 2021 (UTC)Reply[reply]

•  @Narutolovehinata5 and Artem.G: — Yes, you're probably right. Okay then. The article is good to go! -- Gwillhickers (talk) 17:34, 17 October 2021 (UTC)Reply[reply]

• @Gwillhickers and Artem.G: I'm seeing several unsourced paragraphs—as a general rule, each paragraph should have a citation at the end of its last sentence. Any chance that this could be cleared up before I promote? theleekycauldron (talk • contribs) (they/them) 20:53, 21 October 2021 (UTC)Reply[reply]

• Yes, I'll do it today or tomorrow. Artem.G (talk) 06:15, 22 October 2021 (UTC)Reply[reply]
• @Theleekycauldron: done. I've commented one unsourced sentence, and provided refs for all others (it was probably during the rewrite when I swapped these pieces without moving the refs accordingly). Artem.G (talk) 07:01, 22 October 2021 (UTC)Reply[reply]
