Comments
 * 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...)
 * ✅ 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.
 * ✅ Shanze1 (talk) 05:22, 22 April 2020 (UTC)


 * "Satish Dhawan Space Centre on " say where that is.
 * ✅ Shanze1 (talk) 05:22, 22 April 2020 (UTC)


 * " 2.43 PM" -> 2.43 p.m. (with non-breaking space).
 * ✅ Shanze1 (talk) 05:22, 22 April 2020 (UTC)


 * "Vikram lander.[25] Vikram and " repetitive.
 * ✅ Shanze1 (talk) 05:22, 22 April 2020 (UTC)


 * Could link lunar day.
 * ✅ Shanze1 (talk) 05:22, 22 April 2020 (UTC)


 * "A successful soft landing would" I don't think "soft" is necessary.
 * ✅ Shanze1 (talk) 05:12, 24 April 2020 (UTC)


 * " USSR, US and PRC to do so." I would say "Soviet Union, United States and China".
 * ✅ Shanze1 (talk) 05:22, 22 April 2020 (UTC)


 * "The proposed configuration ..." I don't think this is lead material as it's not related to Chandrayaan-2.
 * ✅ Shanze1 (talk)


 * SATCAT no is not referenced. And I know it's getting it from WikiData, but that's not referenced either.
 * ✅ Shanze1 (talk)


 * "(03:32 UTC) [11][12]" no space before refs.
 * ✅ Shanze1 (talk)


 * " UTC) [14][12]" ditto, and ref order.
 * ✅ Will work on the rest shortly. Shanze1 (talk) 05:51, 22 April 2020 (UTC)


 * Inclination, rover power and lander power not referenced in infobox.
 * Added citations for the the power values. Cannot find the inclination mentioned anywhere in official sources. Should I remove inclination now? Shanze1 (talk) 13:16, 27 April 2020 (UTC)


 * " Russian Federal Space Agency (Roscosmos) " just Roscosmos is fine being the common name.
 * ✅ Shanze1 (talk) 05:12, 24 April 2020 (UTC)


 * "per schedule" on schedule sounds more natural to me.
 * ✅ Shanze1 (talk) 05:12, 24 April 2020 (UTC)


 * "January 2013[45] " just move that ref to join the others at the end of the sentence.
 * ✅ Shanze1 (talk) 05:12, 24 April 2020 (UTC)


 * "Roscosmos later withdrew in " withdrew from the CHandrayaan-2 project.
 * ✅ Shanze1 (talk) 05:12, 24 April 2020 (UTC)


 * "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?
 * ✅ Yes, I've rewritten the sentence now. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "India decided to develop the lunar mission independently" hang on, I though you just said Russia withdrew?
 * ✅ I have removed the initial mention, it's only mentioned at the end now. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "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.
 * ✅ 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)


 * "legs got minor" --> "legs received minor"
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "launch was initially scheduled " once again, nope, it was far from the initial schedule...
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "rescheduled.[53][8][54]" ref order.
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "of a GSLV MK III M1" - the M1 was missing in the lead mention of the rocket.
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * " the lunar surface and operate a robotic rover on the surface" repetitive use of "surface".
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "Scientific goals include orbital studies" change of tense from previous sentence (past) to this one (current).
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * And then to the future " The orbiter will map..."...
 * ✅ Followed bullet-list format like in other related articles. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "water ice" is overlinked.
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)

 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)

 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * " As of June 2019, the mission has an allocated cost of ₹ 9.78 billion" it's now April 2020, is this updatable? And link the rupee symbol.
 * ✅ No, it's up to date. Should I remove the "As of June 2019"? Linked rupee symbol. Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "Chandrayaan-2 stack was" --> "The Chandrayaan-2 stack was..." and what's a stack here?
 * Stack is the composite which just the 2 components combined - orbiter+lander.  Shall we use "spacecraft" instead? Shanze1 (talk) 12:47, 27 April 2020 (UTC)


 * "₹ 3.75 billion" convert again.
 * ✅ fixed. Shanze1 (talk) 12:47, 27 April 2020 (UTC)

That takes me to the Payload section. I'll put the article on hold for now, and once these are resolved satisfactorily, I'll move on to later sections. The Rambling Man (Stay indoors, stay safe!!!!) 16:27, 21 April 2020 (UTC)
