Chandrayaan in Hindi

Could you please add Chandrayaan in Devanagari, as it would make more sense for people who know how to read hindi or sanskrit to be able to pronounce it by reading it in Hindi. Also if you check, all other counties have it in their mother tongue when discussing their accomplishments. It says Chandrayaan-1 (transl. Moon-craft, pronunciation (help·info)) Does not contain it in hindi 223.190.89.16 (talk) 23:02, 12 September 2022 (UTC)

Relevance of Information

Some of the information seems to be of little relevance - like the discoveries the rover is expected to make. Shouldn't the article only report on things that are known to be true? If there are aspirations, that's fine to add, but saying that it will discover the presence of water ice on the lunar surface seems a bit presumptuous. SpaceAlex1 (talk) 06:53, 14 July 2023 (UTC)

Chandrayaan-3

Chandrayaan-3 is the third lunar exploration mission by the Indian Space Research Organisation (ISRO). It consists of a lander and the Pragyan rover similar to Chandrayaan-2, but does not have an orbiter. Its propulsion module behaves like a communication relay satellite. The propulsion module carries the lander and rover configuration until the spacecraft is in a 100 km lunar orbit. Following Chandrayaan-2, where a last-minute glitch in the landing guidance software led to the lander crashing after entering lunar orbit, another lunar mission was proposed. The launch of Chandrayaan-3 took place on 14 July 2023, at 2:35 pm IST and lunar injection of 100 km circular polar orbit was completed successfully as part of phase one. The lander and rover are expected to land near the lunar south pole region on 23 August 2023. Background As part of the Chandrayaan programme to demonstrate soft landing on the Moon, ISRO launched Chandrayaan-2 on board a Launch Vehicle Mark-3 (LVM 3) launch vehicle consisting of an orbiter, a lander and a rover. The lander was scheduled to touchdown on the lunar surface in September 2019 to deploy the Pragyan rover. The European Space Tracking (ESTRACK) operated by European Space Agency (ESA) will support the mission according to a contract.Under the new cross-support arrangement, ESA tracking support could be provided for upcoming ISRO missions such as those of India’s first human spaceflight programme, Gaganyaan, the Chandrayaan-3 lunar lander and the Aditya-L1 solar research mission. In return, future ESA missions will receive similar support from ISRO’s own tracking stations. Objective ISRO has set three main objectives for the Chandrayaan-3 mission, which include: Getting a lander to land safely and softly on the surface of the Moon. Observing and demonstrating the rover’s loitering capabilities on the Moon. In-site observation & conducting experiments on the materials available on the lunar surface to better understand composition of the Moon. Design Chandrayaan-3 comprises three main components: Propulsion Module: The propulsion module will carry the lander and rover configuration till 100 km lunar orbit. It is a box-like structure with one large solar panel mounted on one side and a large cylinder on top (the Intermodular Adapter Cone) that acts as a mounting structure for the lander. In addition to the lander, the module carries a payload called Spectro-polarimetry of Habitable Planet Earth (SHAPE) to study the spectral and polarimetric measurements of Earth from the lunar orbit in the near-infrared (NIR) wavelength range (1-1.7 μm). Lander: The lander is responsible for the soft landing on the Moon. It is also box-shaped, with four landing legs and four landing thrusters of 800 newtons each. It will carry the rover and various scientific instruments to perform in-site analysis. The lander for Chandrayaan-3 will have only four throttle-able engines, unlike Vikram on Chandrayaan-2 which had five 800 Newtons engines with a fifth one being centrally mounted with a fixed thrust.[citation needed] Additionally, the Chandrayaan-3 lander will be equipped with a Laser Doppler Velocimeter (LDV). The impact legs are made stronger compared to Chandrayaan-2 and increased instrumentation redundancy. ISRO is working on improving the structural rigidity and adding multiple contingency systems. The lander has three payloads: Chandra's Surface Thermophysical Experiment (ChaSTE) will measure the thermal conductivity and temperature of the lunar surface. Instrument for Lunar Seismic Activity (ILSA) will measure the seismicity around the landing site. Langmuir Probe (LP) will estimate the plasma density and its variations. Rover: Chandrayaan-3 Rover Overview: Six-wheeled design Weight of 26 kilograms (57 pounds) Range of 500 metres (1,600 ft) Scientific instruments including cameras, spectrometers, and a drill Expected lifespan of one lunar day (14 Earth days) Communication with the lander and ground control team in India The rover has two payloads: Alpha Particle X-Ray Spectrometer (APXS) will derive the chemical composition and infer mineralogical composition of the lunar surface. Laser Induced Breakdown Spectroscope (LIBS) will determine the elemental composition (Mg, Al, Si, K, Ca, Ti, Fe) of lunar soil and rocks around the lunar landing site. The Chandrayaan-3 Rover is expected to make a number of important scientific discoveries, including: The composition of the lunar surface The presence of water ice in the lunar soil The history of lunar impacts The evolution of the Moon’s atmosphere Launch Chandrayaan-3 was launched on 14 July 2023, at 2:35 pm IST as scheduled, from Satish Dhawan Space Centre in Sriharikota, Andhra Pradesh, India. The spacecraft has been effectively placed in the trajectory it will take to reach the moon. It is anticipated that the Chandrayaan-3 mission will achieve a soft landing on the lunar South Pole region on 23 August. Choosing the month of July for the launch of Chandrayan 3 was a special move because of a calculation made by ISRO regarding the closeness of Earth and Moon.

Phrasing in the intro

Last para of the intro currently reads, "If the mission succeeds, it will be the first soft landing near the lunar south pole. No landings have occurred near the lunar north pole." To expand on my revert summary for this edit, first landing on a lunar pole, sounds like reductive trivia. For instance, we don't say CY2 was the first spacecraft to land on lunar coordinates 70.90267°S 22.78110°E, even though it's technically true. This is the reason every reliable source mentions "First to Land on Moon’s South Pole." [1][2][3] In my opinion, mentioning "No landings have occurred near the lunar north pole" is unnecessary. @Randy Kryn: — hako9 (talk) 12:18, 23 August 2023 (UTC)

Success

The mission has triumphed in achieving an extraordinary milestone: the first-ever soft landing near the lunar south pole. This accomplishment holds great significance, as it underscores the pioneering spirit of exploration and innovation. By focusing on the achievement of being the "First to Land on Moon’s South Pole," the narrative aptly highlights the historical importance of this mission without delving into overly technical specifics.

The decision to omit the mention of past landings near the lunar north pole serves to keep the introduction concise and focused on the current achievement. This streamlining allows for a more impactful and engaging description of the mission's success. The emphasis remains on the groundbreaking nature of the lunar south pole landing, a feat that has captured the attention of reliable sources and experts alike. 122.179.136.94 (talk) 12:45, 23 August 2023 (UTC)

month of July

"Choosing the month of July for the launch of Chandrayaan 3 was a special move because of a calculation made by ISRO regarding the closeness of Earth and Moon" (with this source) is a very strange statement. The Moon passes perigee every month, why July is better than other months? Sneeuwschaap (talk) 03:01, 22 August 2023 (UTC)

Not disputing the dubiousness of the source, but to answer your question more directly, the moon's orbit is not a perfect circle, so sometimes is closer to the earth. That being said, I don't think this is limited to July each year by any means. This BBC article has more info on the "Buck moon" that is referenced in the source --Molochmeditates (talk) 02:00, 23 August 2023 (UTC)

I believe this statement is indeed misleading. There are no reliable sources pointing out this "calculation made by ISRO". This article on the Indian Express quotes the ISRO chairman as saying that the launch time was selected keeping in mind the sunrise on the Moon, given that the rover is solar powered. I think the statement should be removed from the article. Lord Clayton7 (talk) 13:43, 23 August 2023 (UTC)

Removed. Probably it is based on some true information, but so distorted by journalists, that the sense is impossible to reconstruct. Sneeuwschaap (talk) 15:00, 23 August 2023 (UTC)

Ice confirmed!

"The moon’s south pole has been an area of heightened interest ... as they suspected the existence of ice deposits located inside permanently shadowed craters. Chandrayaan-3 has now confirmed this prediction to be true! This ice offers the potential of critical resources for future astronauts such as air, water, and even hydrogen rocket fuel." —Source: "Celebrating the first landing on the moon’s south pole!"

Criticism

I propose to remove the largest part of the criticism sublemma to the lemma of the author of the criticism, as the criticism has nothing to do with the contents of the mission, but is merely a try to hike on the popularity of the successful mission and to hike on nationalistic sentiments. 2A02:A455:19F3:1:80F9:6C08:E129:27A7 (talk) 07:27, 25 August 2023 (UTC)

1 Lunar Day (14 Earth Days)

Like everyone, I understand that "day" can mean "the span of time when the Sun is up" or "the time between solar noons". Does it bother anyone else that those two definitions are mashed into the same phrase? If an Earth day = 24 hours, then a Lunar day should be 28 * 24 hours, right? If a Lunar day means "duration of sunlight", then an Earth day should be 12 hours. Spiel496 (talk) 18:53, 25 August 2023 (UTC)

@Spiel496 A lunar day is one axial revolution, which equals ~29 Earth days (revolutions). It looks like the ISRO brochure source is being a little sloppy with its definition of "day". Celjski Grad (talk) 19:07, 25 August 2023 (UTC)

NASA describes it as a daylight period instead of a day: “The lander and rover are designed to operate for one lunar daylight period (about 14 Earth days).”

Celjski Grad (talk) 19:15, 25 August 2023 (UTC)

Operations/mission profile

A new heading under “mission profile” should be created called “surface operations” under which its operations/activities on the moon can be placed. Currently there is only a table which is not very streamlined and seems to have not been edited since the actual landing. I think this should be replaced/removed. Finally, the heading “mission profile” is not inherently obvious as the timeline of events, and I suggest this should be replaced with “operations” or “mission timeline”. In my opinion this is less important than fixing surface operations. 197.234.165.147 (talk) 11:01, 26 August 2023 (UTC)

Though I do not have the answer to your question, what could be relevant in evaluating whether that information should be in the artilce is why should that piece of information be in the article? I am not saying it should or should not, but when making a request, especially for something specific related to the article, knowing why it should be in the article helps determine if it should be added. Just my two cents. Jurisdicta (talk) 11:21, 29 August 2023 (UTC)

It is quite important the landing and subsequent operations are during a Lunar day (sun shines). See "Both spacecraft will spend the remaining roughly 12 days of lunar sunlight carrying out activities and experiments. Neither are expected to survive the lunar nighttime, during which temperatures will drop to around minus 130 Celsius."and "The module would undergo internal checks and await the sun-rise at the designated landing site."―― Phoenix7777 (talk) 12:03, 29 August 2023 (UTC)

An English name? when did "chadrayaan" became an English word? its a tatsama Hindi word from Sanskrit candra-yāna. Also WP:NOINDICSCRIPT talks about adding Indic scripts as in adding <चंद्रयान> not their IPA. Almost all major pages having non English names gives primarily IPA pronunciation of the language the term is from and only optionally English IPA, see Iran, Gdańsk or Augusto_Pinochet.

• • Chandrayaan-3 Mission:**

On [30th, August-2023], the Indian Space Research Organisation (ISRO) shared an exciting update on their official Twitter account regarding the Chandrayaan-3 Mission. The update featured an image captured by the Pragyan Rover, showcasing the Vikram Lander. This remarkable photograph, often referred to as the 'image of the mission,' was taken using the Navigation Camera (NavCam) aboard the Rover. Notably, the NavCams utilized for the Chandrayaan-3 Mission were developed by the Laboratory for Electro-Optics Systems (LEOS). This development highlights ISRO's commitment to utilizing cutting-edge technology and collaborations to advance space exploration.

Inclusion of a link.

If the argument against my initial addition is that the link to the "Lunar south pole" is already provided above in the lead, then the same logic applies to the link to the Chandrayaan programme. Therefore, the link to the programme should also be reconsidered for removal based on that rationale.

The Lunar south pole article offers detailed insights into the scientific aspects associated with the region, encompassing its cold traps, water ice, and historical significance within the context of the Solar System. This content complements the information presented in the "Background Section" by providing a more expansive exploration of the subject matter. The background precisely discusses this, "The lunar South Pole region holds particular interest for scientific exploration due to studies that show large amounts of ice there. Mountainous terrain and unpredictable lighting conditions not only protect the ice from melting but also make landing scientific probes there a challenging undertaking. This ice could contain solid-state compounds that would normally melt under warmer conditions elsewhere on the Moon – compounds that could provide insight into lunar, Earth, and Solar System history. Ice could also be used as a source of drinking water and hydrogen for fuel and oxygen for future manned missions and outposts." It is of high relevance. WP:Relevance.

My argument against the inclusion of the link to "Lunar south pole" was predicated on the relevance of it, and not the article's usefulness. In the section, "Background" it seems more appropriate to include a link to the "Chandryaaan programme", as it provides the necessary background information about the programme, of which the Chandrayaan-3 is a part. Also, two links placed under the header seems information overload, but this is a minor issue. Lord Clayton7 (talk) 07:35, 2 September 2023 (UTC)

PM is a relay satellite

The every parameter of propulsion module shows it as a relay satellite even ISRO has stated that PM will use for communication with Lander. Asadf25 (talk) 05:27, 19 August 2023 (UTC)

ISRO Chairman in past suggested that but latest information by him affirms that Propulsion Module will not act as relay and after separation is completely independent. See this presentation (@01h08m) and this (@17m25s). Chandrayaan-2 Orbiter will act as relay.  Ohsin  11:15, 19 August 2023 (UTC)

OK but PM will be active after separation and it has a instrument too which clearly shows it as a orbiter if not relay than its a orbiter for sure. Asadf25 (talk) 16:06, 19 August 2023 (UTC)

Propulsion unit had the main task of helping lander to reach lunar orbit. It is an orbiter for sure, but its main task is not to relay any kind of information, after the spacecraft has landed (Relaying will be done by Chandrayaan 2 Orbiter Module). However, the propulsion module has a Spectro-polarimetry of Habitable Planet Earth Payload which will be used take few measurements of Earth from lunar orbit.

NPOV issues?

I'm seeing a lot of statements that seem to gloss over things or make strange incorrect statements that Chandrayaan-3 made the first discovery of something that's been already well known. Anything that can be done about this? Should the NPOV template be added? Ergzay (talk) 19:01, 4 September 2023 (UTC)

Photomontage

Either please change lead from current image to previous earth stack image or please change lead from current image to photomontage of Vikram, Pragyan and PM (images linked) 122.187.144.98 (talk) 15:47, 31 August 2023 (UTC)

"Lunar south polar region"

The second paragraph of the lead and several other places uses the phrase "lunar south polar region". Which is inaccurate as the landing sight is 69°22′22.8″S, 32°19′8.4″E. It is commendable that ISRO landed this far south on the moon. But calling the region "polar" is wrong. Lunar antarctic circle is 80°S. Thus the present location of rover or lander is not polar. In the initial brochure released by ISRO the site of landers' functioning is called "near polar region", which is accurate. There is difference between "near polar" and "polar". Physical Research Laboratory under the Department of Space which investigated the landing site(s) prior to the launch also does not use terms like "lunar south polar region" ChandlerMinh (talk) 16:04, 6 September 2023 (UTC)

Regarding the Domestic reactions

Domestic reactions too specific, like what is the role of DY Chandrachud and Arvind Kejriwal? If we go by this logic, then the reaction of every important personality on twitter should be given! . Maybe just omit this section excluding ISRO Chairman S. Somnath and Prime Minister Narendra Modi's message. Instead I would suggest a domestic reaction where the symbolic representation of CY3 by common Indians and their reactions, and add an international reactions section. 122.252.251.250 (talk) 20:05, 6 September 2023 (UTC)

Chandrayaan-3 (/ˌtʃʌndrəˈjɑːn/ CHUN-drə-YAHN) is the third mission in the Chandrayaan programme, a series of lunar-exploration missions developed by the Indian Space Research Organisation (ISRO). Launched on 14 July 2023, the mission consists of a lunar lander named Vikram and a lunar rover named Pragyan, similar to those launched aboard Chandrayaan-2 in 2019. Chandrayaan-3 was launched from Satish Dhawan Space Centre on 14 July 2023. The spacecraft entered lunar orbit on 5 August, and the lander touched down near the lunar south polar region on 23 August at 18:03 IST (12:33 UTC), making India the fourth country to successfully land on the Moon, and the first to do so near the region of the lunar south pole. On 3 September the lander hopped and repositioned itself 30–40 cm (12–16 in) from its landing site. The Vikram lander and Pragyan rover were set to sleep on 2 September and 4 September respectively due to depleting solar power with sunset at the landing site. The lander and rover are planned to start working again at local sunrise on September 22. 1.38.98.93 (talk) 14:47, 13 September 2023 (UTC)
