Full Version: Chandrayaan 3 lander and rover
Not long ago there was the info that the launch had slipped to 2023.
But then it was told "August 2022".
Let's wait and see...

New payload inclusion, it would be mounted atop propulsion module.

QUOTE
The propulsion module will carry the lander till lunar orbit insertion and deployment of lander. After that, the module will be utilised for science payload operations
QUOTE
The propulsion module is configured to carry a science payload to observe Earth from the lunar orbit.

SHAPE: Spectro-polarimetry of Habitable Planet Earth onboard Chandrayaan-3
SHAPE is an experiment on-board Chandrayaan-3 Mission for the study of spectropolarimetric signatures of the habitable planet Earth in the near-Infrared (NIR) wavelength range (1 – 1.7 µm). The spectro-polarimeter is mounted on the Propulsion Module (PM) of Chandrayaan-3 mission. The payload will observe full-disc Earth from a distant vantage point, Moon, in order to ‘mimic’ Earth-like Exo-planets.
SHAPE is being designed with two packages:
(1) Electro-optical Detector System (EODS)
(2) Radio Frequency Source (RFS).

Chandrayaan 3 may be slipping to the end of 2023 (or just beyond). Here is an LPSC abstract on landing sites with 8 candidates.

In that abstract, I am really confused by the labeling of some of the landing sites on the lunar picture as compared to the latitudes listed in the adjoining table.
They are all negative latitudes (i.e. south latitudes) - look closely and you will see the negative signs. I have not mapped those points yet but I didn't notice a problem on a first read.
Site 5 is the Chandrayaan 2 site.
Phil
Site 5 is the Chandrayaan 2 site.
Phil
Ok... I was wrong in my previous post. Sorry about that. I looked at the maximum and minimum ranges of latitude and longitude in the table and on the map and they were essentially the same. But now I am mapping them I find that the site numbers do not match between the table and the map. For instance, site 1 in the table seems to be site 8 on the map. The numbering doesn't match the ranking either.
Here is a map with the numbers from the table in red.

I think I have tracked down the source of the discrepancy. This abstract from the 2021 LPSC:
https://www.hou.usra.edu/meetings/lpsc2021/pdf/1396.pdf
shows exactly the same map but refers to the sites as areas of interest and discusses mapping them using the OHRC camera on Chandrayaan 2.
I think that the new abstract uses a renumbered list of landing site candidates but repeats the old map without updating it.

The very useful blog by Jatan Mehta contains an interesting update about Chandrayaan 3. A presentation at a recent conference (too bad we don't have public abstracts!) gave the backup landing site for the mission. It's not, as one might have suspected, one of the eight sites discussed above. It is further west, at 69.49° S, 17.33° W. This is close to the backup site for Chandrayaan 2's lander Vikram.
On that subject... will this lander be Vikram 2 or will it get a new name? Will its rover be Pragyan 2 or will it get a new name? We should know fairly soon.

I have made maps showing my current understanding of the Chandrayaan 3 landing sites. The first map shows the two candidates (larger circles) discussed in 2021, the 8 candidates from earlier this year and the site chosen for the landing, as well as the site of the Vikram crash from Chandrayaan 2. The second map shows the alternative site and the alternative for Chandrayaan 2.
If anyone has any corrections especially for the Hindi names I will be pleased to get them. I have been looking for a map of the Moon labelled in Hindi or any other Indian language, but so far I have not been able to find anything. Tips would be appreciated.

Thanks for this. So not Vikram 2 and Pragyan 2, as they could have chosen. I seem to recall at the time of Chandrayaan 2 that there was a plan to name the landing site as well, but it was never done because the landing was not successful. I hope this one is successful!

Chandrayaan-3 Mission:
The orbit-raising maneuver (Earth-bound perigee firing) is performed successfully from ISTRAC/ISRO, Bengaluru.
The spacecraft is expected to attain an orbit of 127609 km x 236 km. The achieved orbit will be confirmed after the observations.
The next firing, the TransLunar Injection (TLI), is planned for August 1, 2023, between 12 midnight and 1 am IST.

Chandrayaan-3 Mission:
Chandrayaan-3 completes its orbits around the Earth and heads towards the Moon.
A successful perigee-firing performed at ISTRAC, ISRO has injected the spacecraft into the translunar orbit.
Next stop: the Moon ��
As it arrives at the moon, the Lunar-Orbit Insertion (LOI) is planned for Aug 5, 2023.

Chandrayaan-3 Mission:
The spacecraft’s health is normal.
Today’s perigee burn has successfully raised Chandrayaan-3 orbit to 288 km x 369328 km.
In this orbit, the spacecraft enters the moon’s sphere of influence.
A crucial maneuvre at perilune would achieve the Lunar Orbit Injection (LOI).

Chandrayaan-3 Mission: Update
Today, the Chandrayaan-3 mission achieved a crucial milestone with the successful completion of the Lunar Orbit Insertion (LOI). The insertion was carried out by retro-burning at the Perilune for 1835 seconds, starting at 19:12 Hrs. IST. The maneuver resulted in an orbit of 164 km x 18074 km, as intended.
This is the third time in succession that ISRO has successfully inserted its spacecraft into the lunar orbit, apart from doing so once into the Martian orbit.
As the mission progresses, a series of maneuvers have been planned to gradually reduce Chandrayaan-3's orbit and position it over the lunar poles. After some manevres, the propulsion module will separate from the lander while in orbit. Following that, a series of complex braking maneuvers will be executed to facilitate a soft landing in the South Polar region of the Moon on August 23, 2023. The health of Chandrayaan-3 is normal. Throughout the mission, the health of the spacecraft is being continuously monitored from the Mission Operations Complex (MOX) at ISRO Telemetry, Tracking, and Command Network (ISTRAC), the Indian Deep Space Network (IDSN) antenna at Byalalu, near Bengaluru, with the support from ESA and JPL Deep space antenna.
The next Lunar bound orbit maneuver is scheduled for August 6, 2023, between 22:30 and 23:30 Hrs. IST.

Chandrayaan-3 Mission:
The spacecraft successfully underwent a planned orbit reduction maneuver. The retrofiring of engines brought it closer to the Moon's surface, now to 170 km x 4313 km.
The next operation to further reduce the orbit is scheduled for August 9, 2023, between 13:00 and 14:00 Hrs. IST.
