I will review this shortly. AhmadLX-)¯\_(ツ)_/¯) 16:12, 1 July 2019 (UTC)

Misc

• Earwig's shows some close paraphrasing from one source.
  • This has been fixed. Only close paraphrasing is from the PD NASA source. Kees08 (Talk) 16:41, 11 July 2019 (UTC)
• Lead is very short and not a representative summary of the article body. Please expand it.
  • Expanded Kees08 (Talk) 16:41, 11 July 2019 (UTC)
• The main contributor of the article seems to be user:Kees08. I couldn't find any consultation on your part with the said editor as required by the procedure.

Me and Kees08 are working on a dozen articles together. Rest assured, we are in agreement on this. See Wikipedia talk:WikiProject Space 2019/DYK for just one of the many places we are in discussion including about nominating this article for DYK after GAN is completed. --- Coffeeandcrumbs 18:08, 1 July 2019 (UTC)

Its all good; I will watchlist this and participate as needed. Kees08 (Talk) 18:27, 1 July 2019 (UTC)

• Link Doppler shift, booster, Space Race, Eisenhower.
  • Done. --- Coffeeandcrumbs 13:56, 4 July 2019 (UTC)
• If you are writing "U.S.", also write USSR as U.S.S.R, not as USSR. See MOS:US
  • Done. --- Coffeeandcrumbs 13:56, 4 July 2019 (UTC)
• "Although Luna 2 was a success for the Soviets,it also helped the U.S. by starting a trend of crash landing. ..." doesn't fit in section "Cultural Significance". Add it to the preceding section, or a new section "Aftermath".
  • Done. --- Coffeeandcrumbs 13:56, 4 July 2019 (UTC)
• Please remove duplinks.
  • Done. --- Coffeeandcrumbs 15:25, 4 July 2019 (UTC)
• Remove "Zarya - Luna 2 chronology" from external links: it is already used as a source.
  • Done. --- Coffeeandcrumbs 15:25, 4 July 2019 (UTC)
• "The scintillation counters would be used to measure any ionizing radiation; the Cherenkov radiation detectors would be measuring for electromagnetic radiation caused by charged particles." Why semicolon, why not "and"
  • Done. Why not indeed. --- Coffeeandcrumbs 15:25, 4 July 2019 (UTC)
• "The last instrument on Luna 2 was, "a three component fluxgate...". Why comma here?
  • Done. Sorry for the lack of a good copy-editing. --- Coffeeandcrumbs 15:25, 4 July 2019 (UTC)
• " ...to greatly reduce the energy upon reaching the surface...". Use impact force or impact velocity here.
  • Done. --- Coffeeandcrumbs 15:25, 4 July 2019 (UTC)
• "It was a capsule filled with liquid, with aluminium strips placed into it." It is not explained what was the purpose of the liquid.
  • The only reference I have seen to liquid so far is from Don Mitchell. He has commented on this talk page so we could ask him and that would help find an RS for it. Kees08 (Talk) 17:30, 10 July 2019 (UTC)
• "Launch was scheduled for 9 September". Add year.
  • Looks like Coffeeandcrumbs got this. Kees08 (Talk)
• "took a direct path to the Moon, with a velocity high enough to result in a travel time of around 36 hours." Infobox says launch to impact interval "1 day, 14 hours".
  • Done. --- Coffeeandcrumbs 09:13, 6 July 2019 (UTC)
• "visible disk on 1959 September 13". Be consistent with date format.
  • Done. --- Coffeeandcrumbs 09:13, 6 July 2019 (UTC)
• "The satellite's impact made it the first man-made object to crash-land on another celestial body." Was there any controlled landing before? If no, then make it land/hit/impact or something similar.
  • Done. --- Coffeeandcrumbs 09:13, 6 July 2019 (UTC)
• "cloud that would expand to 650-kilometer (400 mi) diameter that would be seen". Cut this "that would" please. Why not "cloud that expanded to 650-kilometer (400 mi) diameter and was seen"?
  • Rephrased similar to that. Kees08 (Talk)
• "Americans were still skeptical until Bernard Lovell was able to prove that the radio signal was coming from Luna 2". Please introduce him first: scientist/atrophysicist or whatever he was.
  • Adapted some text from Zond 5 that explains it Kees08 (Talk)
• "was about 37,000 miles (60,000 km)". Reverse order to be consistent.
  • Reversed Kees08 (Talk)
• "Donald W. Cox explains...". Replace this "explains" with something more appropriate: writes/claims/argues etc. "Explains" is taking sides here. American probes also didn't provide "cars, refrigerator" to the people.
  • Used 'wrote' Kees08 (Talk)

Sources & Verifiability

• Three paras unreferenced and a cn tag.
  • Fixed Kees08 (Talk)
• Zak, Anatoly ([3]) only confirms that there were 3 failures before Luna 1. The rest isn't supported by it.
  • Addressed. --- Coffeeandcrumbs 09:45, 6 July 2019 (UTC)
• Harvey 2007, p. 22–24 doesn't support the claim "were not given official names".
  • p. 24 says "Only successful launchings and successful mission outcomes would be announced, [ Mikhail Suslov ] decreed..." I paraphrased that to Luna missions that failed to successfully launch or achieve good results were not publicly acknowledged. --- Coffeeandcrumbs 09:45, 6 July 2019 (UTC)
• Koren, Marina ([6]) doesn't say that Luna 2 was similar to Luna 1. It would be fine to use this source, if you have already described Luna 1's design with some other source.
  • Found alternative sources that do. --- Coffeeandcrumbs 20:00, 8 July 2019 (UTC)
• Christy, Robert ([6]) and NASA-NSSDCA ([7]) don't support the following: "scintillation counters, Cherenkov detectors"
  • Added RS for scintillation. Sources refer to a "Cosmic ray detector" not a Cherenkov detector. --- Coffeeandcrumbs 20:00, 8 July 2019 (UTC)
• and that "There were no propulsion systems on Luna 2 itself."
  • Cited Kees08 (Talk)
• Why is the instrument description copy-pasted from sources "Geiger Counter" ([9]) and "Triaxial Fluxgate Magnetometer" ([11])?
  • It is a NASA source so it is PD. Kees08 (Talk)
• "Luna 2 carried five different instruments to conduct various tests while it was on its way to the Moon. The scintillation counters would be used to measure any ionizing radiation; the Cherenkov radiation detectors would be measuring for electromagnetic radiation caused by charged particles." is not supported by "Geiger Counter" ([9]). If "Lunar Impact capsule" ([10]) is meant, then it should be added to this specific claim.
  • clarified what sources support that --Spacepine (talk) 14:28, 11 July 2019 (UTC)
• Please arrange citations in the 2nd para of section "Payload" in such way that it is clear what claim is supported by which source. Now it appears as though all 4 sources support everything in the paragraph-which is not the case.
  • Coffeeandcrumbs has taken care of this. Kees08 (Talk) 06:26, 11 July 2019 (UTC)
• Ivanov, Stepan (12 September 2017) doesn't say that "Luna 2 hit the Moon about 800 kilometers (500 mi) from the centre of the visible disk on 1959 September 13 at 21:02:24 UTC."
  • Coffeeandcrumbs changed to coordinates and cited those Kees08 (Talk)
• According to Harvey 2007, p. 30–34 impact speed was 3km/s (10800km/hr)
  • Changed. --- Coffeeandcrumbs 20:00, 8 July 2019 (UTC)
• "The last stage of the rocket that carried Luna 2 did not carry any type of tracking device" isn't supported by "Luna 2" NASA. Should be replaced with Harvey 2007, p. 30–34.
  • Well, Harvey 2007, p. 31 and p. 33, seem to contradict each other about whether the last stage had a transmitter or not. But Mitchell 2008 confirms the last stage did have a transmitter, which could theoretically be used for tracking. I have chosen to omit a reason for why a location for the impact site was not calculated as the reason seems uncertain from comparing the sources. It is possible they just never bothered. --- Coffeeandcrumbs 13:12, 11 July 2019 (UTC)
• "as soon as the scientists of Luna 2 started receiving transmissions they sent out" suggests they made the details public. Source (Harvey) suggests they sent them to Americans only.
  • They sent tracking info only to Lovell in Englang. Now addressed. --- Coffeeandcrumbs 13:12, 11 July 2019 (UTC)
• Now that you have Harvey 2007 and other books in footnote format, please cite things by specific page numbers, instead of ranges like 30–34.
  • Done as suggested in the process of addressing other concerns. --- Coffeeandcrumbs 20:20, 9 July 2019 (UTC)
• "After this no one seemed to question the veracity of the Soviets." is not in Harvey 2007 p. 30-34.
  • Harvey says "that seemed to satisfy most [of the reporters]". I have made the article say something similar. --- Coffeeandcrumbs 20:20, 9 July 2019 (UTC)
• Harvey 2007, p. 34 talks about detection of lunar ionosphere. Any reason you haven't mentioned it?
  • Done. --- Coffeeandcrumbs 20:20, 9 July 2019 (UTC)
• "Khrushchev, on his only visit to the U.S., gave President Eisenhower a replica of the Soviet pennants that Luna 2 had just placed onto the lunar surface." is supported by many sources- Harvey, History today etc. Why not use one of them instead of inaccessible Daniloff, N. (1972)?
  • No particular reason. Kees08 (Talk) 06:04, 11 July 2019 (UTC)
• "The only other known copy of the spherical pennant is located at the Kansas Cosmosphere". Cited source doesn't say that it is "the only other known copy of the spherical pennant".
  • Changed sentance. Now supported by source --Spacepine (talk) 13:58, 11 July 2019 (UTC)
• "NASA used crash landings to test whether Moon craters contained ice by crashing impactors into craters and testing the debris that got thrown out". The source used here is from 2006 and says that Nasa "plans" to do it in 2008. You will have to find more recent source to claim that they "did".
  • Replaced reference with one from 2010 --Spacepine (talk) 13:38, 11 July 2019 (UTC)
• One parameter in infobox is referenced, the rest are not.
  • If referenced in the text it is not needed to reference them again in the infobox, so we just need a cite for Harvard designation, SATCAT no, manufacturer, and launch site (mostly noting this so I can cross them off as I add them). Kees08 (Talk) 16:46, 10 July 2019 (UTC)
  • Giving up for the moment, but for the Harvard designator, it looks like it might be [[1]] which would correspond to the Greek Epsilon which is different than Xi which we have now. The earliest list I can find starts at 1960 Kees08 (Talk) 17:28, 10 July 2019 (UTC)
    • Done with these Kees08 (Talk) 06:03, 11 July 2019 (UTC)
• Please use "Ogurtsov, Maxim; Jalkanen, Risto; Lindholm, Markus; Veretenenko, Svetlana (2 January 2015)." and other books in short-footnote like the four that already are in sfn.
  • Done Kees08 (Talk)
• When citing books, use year of publication instead of date: ABC (2010) instead of ABC (24.10.2010).
  • Done Kees08 (Talk) 04:01, 11 July 2019 (UTC)
• Every article in "Space Exploration and Humanity: A Historical Encyclopedia" is written by a named author. Include this in the bibliography: ABC (2010). "XYZ". In Johnson, Stephen Barry (ed.). Space Exploration and Humanity: A Historical Encyclopedia.ABC-CLIO. For this you will have to use cite encyclopedia template instead of cite book. Remove page number from the template.
  • Done. --- Coffeeandcrumbs 13:12, 11 July 2019 (UTC)
• How can The space race; from Sputnik to Apollo, and beyond be published in 1962 when that was just the beginning of the Space Race? I as having issues finding more information on it online. Kees08 (Talk) 16:33, 9 July 2019 (UTC)
  • Kees08, Are you asking me or the other editor?AhmadLX-)¯\_(ツ)_/¯) 16:48, 9 July 2019 (UTC)
    • Sorry I thought I put a single bullet; asking Coffeeandcrumbs, figured it made more sense here than the talk page, if that's okay. Otherwise I can move it. Kees08 (Talk) 16:51, 9 July 2019 (UTC)
      • Okay no problem. I thought you were asking me and I was like "how would I know" ;) Sorry for the confusion. AhmadLX-)¯\_(ツ)_/¯) 17:05, 9 July 2019 (UTC)
      • @Kees08: It certainly exists according to this Kirkus Review and the Library of Congress has 2 copies. I can go check it out if need be but I won't be at LOC for another few weeks. Probably one of the first instances of the term "Space Race" being used in print media. --- Coffeeandcrumbs 18:56, 9 July 2019 (UTC)

Please note that "hold" is for seven days and will end on 11 July. Thanks. AhmadLX-)¯\_(ツ)_/¯) 14:09, 8 July 2019 (UTC)

Images

• File:Block-E rocket stage.png: Source is another file, whose source link is broken.
  • Fixed the link, and updated some of the parameters on the version we are using on the page. Kees08 (Talk) 18:40, 1 July 2019 (UTC)
• File:Moon map Luna 17 Luna 2 Apollo 15 Surveyor 6 Surveyor 4 Luna 7 Luna 8 Luna 11.png doesn't seem to be "own work".
  • Per the file description, Created using public domain moon maps in the Marble program, cropped with GIMP. I think the licensing should be fine as-is. Kees08 (Talk) 18:40, 1 July 2019 (UTC)

@Coffeeandcrumbs: Is there anything else you are aware of that needs addressed? I will take another look after work. Kees08 (Talk) 16:41, 11 July 2019 (UTC)

I don't think so. @AhmadLX: is there is anything we missed? --- Coffeeandcrumbs 16:58, 11 July 2019 (UTC)

Passing on the assumption that you will take care of the English variety: I see "kilometre" as well as "quantization", please check for others. Otherwise nice work, congratulations. AhmadLX-)¯\_(ツ)_/¯) 18:33, 11 July 2019 (UTC)
