The first thing I noticed was the poor quality of prose in the sections on international cooperations, statistics and heads of ISRO.
In the section "International cooperations", it states too many countries (literally all the way from Afghanistan to Vietnam), and it appears to use definition lists instead of standard subheadings. It also has strange underlining in the section on NISAR (statements should not normally be underlined in Wikipedia).
In the section "Statistics", it only said when it was last updated, and other statistics in bullet points, and then includes a large table. I am not sure what to do with this.
The section "Heads of ISRO" is completely unsourced and all it is is an ordered list and a statement saying it is a list of chairpersons, with incorrect grammar and capitalisation (List of Chairpersons (since 1963) of ISRO. should be This is a list of chairpersons of ISRO, starting at 1963.). ozmoozmo@enwiki$t.c 07:43, 23 April 2026 (UTC)
- This article covers every aspect of ISRO in detail, and seems to not be written from a summary style. Each section is quite long and could be split into its own article, and there are over 10 sections. ozmoozmo@enwiki$t.c 00:13, 24 April 2026 (UTC)
- Could you please tell me which sections those are? Please let me know whether they need to be removed from this article or they need to be upgraded. – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 04:12, 24 April 2026 (UTC)
- In specific, the organisation structures and facilities section should be perhaps split into a list and then the section shortened per WP:SS as it is very long, covers less important aspects of the topic and not crucial to understanding the topic (at least in my knowledge). Comparing this to a similar article NASA, only the history section is this long. ozmoozmo@enwiki$t.c 04:37, 24 April 2026 (UTC)
- I have shortened the section as suggested, and shifted the information to another article. Let me know if there is any other changes to be made in organisation structures and facilities section. – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 05:22, 24 April 2026 (UTC)

- Additionally, let me know what to do with the 'statistics' section. – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 04:15, 24 April 2026 (UTC)
- I am not actually sure what to do with the statistics section. It isn't present in a similar article, NASA, though. Perhaps a second opinion would help, because I haven't reviewed articles of this length before. ozmoozmo@enwiki$t.c 04:40, 24 April 2026 (UTC)
- So what's the second opinion? – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 04:45, 24 April 2026 (UTC)
- Should I remove the section entirely or is there something else I can do? – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 04:47, 24 April 2026 (UTC)
- Oh! The second opinion is something new I am about to encounter. – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 04:49, 24 April 2026 (UTC)
- As I said, I don't know what to do with the statistics section. ozmoozmo@enwiki$t.c 11:27, 24 April 2026 (UTC)
- The information in the statistics section regarding the number of launches and re-entry missions conducted by ISRO is fine; however, the table detailing ISRO's budget does not seem relevant to me. Should I delete it entirely? – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 11:35, 24 April 2026 (UTC)
- Now that you told me, I think the budget section should be deleted (the section on budgets seems to fail
WP:STATSWP:NOTSTATS). And also, please convert it to prose instead of just an embedded list, in order to improve the quality of the prose. ozmoozmo@enwiki$t.c 11:47, 24 April 2026 (UTC)
Done, Is it good to go now or is there something else to add or remove? – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 11:57, 24 April 2026 (UTC)

It serves as the principal research and development arm of the Department of Space (DoS), overseen by the Prime Minister of India, with the Chairman of ISRO also serving as the chief executive of the DoS. It is primarily responsible for space-based operations, space exploration, international space cooperation and the development of related technologies.[3] ? Maybe N NoN NoY Yes? Maybe, meets WP:PRI ? PresentFormerly, ISRO was known as the Indian National Committee for Space Research (INCOSPAR), which was set up in 1962 by then-Prime Minister Jawaharlal Nehru on the recommendation of scientist Vikram Sarabhai.

PresentUnder the government of Indira Gandhi, INCOSPAR was superseded by ISRO. Later in 1972, a space commission and Department of Space (DoS) were set up to oversee space technology development in India specifically.

For second ref: N Does not explicitly state institutionalising space research.Y space.com ref added and DOSHQ ref removed.Efforts to develop an orbital launch vehicle began after mastering sounding rocket technology. The concept was to develop a launcher capable of providing sufficient velocity for a mass of 35 kg (77 lb) to enter low Earth orbit. It took 7 years for ISRO to develop Satellite Launch Vehicle capable of putting 40 kg (88 lb) into a 400-kilometre (250 mi) orbit. An SLV Launch Pad, ground stations, tracking networks, radars and other communications were set up for a launch campaign. The SLV's first launch in 1979 carried a Rohini technology payload but could not inject the satellite into its desired orbit. It was followed by a successful launch in 1980 carrying a Rohini Series-I satellite, making India the seventh country to reach Earth's orbit after the USSR, the US, France, the UK, China and Japan. RS-1 was the third Indian satellite to reach orbit as Bhaskara had been launched from the USSR in 1979. Efforts to develop a medium-lift launch vehicle capable of putting 600-kilogram (1,300 lb) class spacecrafts into 1,000-kilometre (620 mi) Sun-synchronous orbit had already begun in 1978.[21] Y Publisher generally reliable per WP:NPPSG.Y YesY YesY Sigcov.
I got Qwen3.5 to OCR the source, and I would say thatN the source does not mention the development timeline, the failure of a SRV payload in 1979, or the year 1980, or being the seventh country, or sounding rocket technology mastery. It only supports the statement about 35 kg and 600 kg spacecraft.N See left.Y Ref added.They would later lead to the development of the Polar Satellite Launch Vehicle (PSLV).[22] Y Yes.N No.N No.?

- Despite an extensive search, I was unable to locate a secondary reliable source regarding ISRO employees. I encountered the same difficulty in the budget section; consequently, I removed the reference, as no citation for the budget is available at NASA either. – 𝙰𝚔𝚜𝚑𝚊𝚍𝚎𝚟™ 𝚃𝚊𝚕𝚔 01:15, 25 April 2026 (UTC)
On hold because I have to finish reviewing Augmented triangular prism, of which I did not see the nominator's reply until 3 days after. ozmoozmo@enwiki$t.c 02:06, 27 April 2026 (UTC)- I should write a user script that semi-automates the source spot checking. Well, I'll go do that. ozmoozmo@enwiki$t.c 08:13, 27 April 2026 (UTC)
This review may take longer than normal due to the length of this article and the fact that I have other things to do on Wikipedia. ozmoozmo@enwiki$t.c 02:21, 25 April 2026 (UTC)
