  • I always advocate removing refs from the lead. There should be literally nothing in the lead which isn't in the article (and better, expanded upon) so referencing there is best, and leaves a lovely clean, easy to read lead, instead of one littered with interrupting refs (more than 20 in this case...)
  Done Removed and moved most citations. Had to tweak few sentences and a paragraph. Please take a brief look at the lead again. In an attempt to remove the last citation, I added this new line "The name Chandrayaan means "mooncraft" in Sanskrit and Hindi." to Design section. Shanze1 (talk)
  • "currently" see WP:CURRENTLY. This should probably be replaced with "as of 2020" or similar.
  Done Shanze1 (talk) 05:22, 22 April 2020 (UTC)Reply
  • "Satish Dhawan Space Centre on " say where that is.
  Done Shanze1 (talk) 05:22, 22 April 2020 (UTC)Reply

  Done Shanze1 (talk) 05:22, 22 April 2020 (UTC)Reply
  • "A successful soft landing would" I don't think "soft" is necessary.
  Done Shanze1 (talk) 05:12, 24 April 2020 (UTC)Reply
  • " USSR, US and PRC to do so." I would say "Soviet Union, United States and China".
  Done Shanze1 (talk) 05:22, 22 April 2020 (UTC)Reply
  • "The proposed configuration ..." I don't think this is lead material as it's not related to Chandrayaan-2.
  Done Shanze1 (talk)
  • SATCAT no is not referenced. And I know it's getting it from WikiData, but that's not referenced either.
  Done Shanze1 (talk)
  • "(03:32 UTC) [11][12]" no space before refs.
  Done Shanze1 (talk)
  • " UTC) [14][12]" ditto, and ref order.
  Done Will work on the rest shortly. Shanze1 (talk) 05:51, 22 April 2020 (UTC)Reply
  • Inclination, rover power and lander power not referenced in infobox.
  Partly done: Added citations for the the power values. Cannot find the inclination mentioned anywhere in official sources.   Question: Should I remove inclination now? Shanze1 (talk) 13:16, 27 April 2020 (UTC)Reply
  • " Russian Federal Space Agency (Roscosmos) " just Roscosmos is fine being the common name.
  Done Shanze1 (talk) 05:12, 24 April 2020 (UTC)Reply

  Done Shanze1 (talk) 05:12, 24 April 2020 (UTC)Reply
  • "January 2013[45] " just move that ref to join the others at the end of the sentence.
  Done Shanze1 (talk) 05:12, 24 April 2020 (UTC)Reply
  • "Roscosmos later withdrew in " withdrew from the CHandrayaan-2 project.
  Done Shanze1 (talk) 05:12, 24 April 2020 (UTC)Reply
  • "the technical aspects connected " reads weird. Do you mean some of the design for the failed mission were also going to be used for this project?
  Done Yes, I've rewritten the sentence now. Shanze1 (talk) 12:47, 27 April 2020 (UTC)Reply
  • "India decided to develop the lunar mission independently" hang on, I though you just said Russia withdrew?
  Done I have removed the initial mention, it's only mentioned at the end now. Shanze1 (talk) 12:47, 27 April 2020 (UTC)Reply
  • "The spacecraft's launch had been scheduled for March 2018..." well no, I guess you mean the reschedule following ISRO going it alone was first slated for March 2018.
  Done added "initially after the India's decision" at the end of that sentence. I'm not sure if that fixes the problem though. Shanze1 (talk) 12:47, 27 April 2020 (UTC)Reply
