Haven't heard about any official news on an RTEG for Chandrayaan-4 ---- but 2 years back, there was an EOI from ISRO for a 100W RTEG(similar in class to the RTG onboard NASA's Curiosity Mars rover).

Whereas, the JAXA brochure for their lunar program shows the LUPEX mission having an "Operation period" for over "half a year". So, I don't know how we'll manage to stay online for that long without a proper RTEG or RHU?

Another option sans an RTEG or RHU could be through chemical heating and insulation like in the Chinese Zhuron Mars rover. Don't know how effective that'll be. Last I heard, the Chinese were having issues receiving signals from the Zhurong. But, what other option is there if an RTEG or RHU proves to be too complex to develop in time?

ISRO & BARC's RTEG efforts have more than been a decade long.
It has nothing to with Chandrayaan-4. Nor they will be used on it as they are nowhere in sight.

Any one knows what's the time lag b/w transmission and reception of images/signals here?

 

[thebakofbakchod]

Man this better land properly. I spoke too much shit to seething brits and pakis online

 

[Tactical Doge]

So isro just give the schematics and they build it eh?

I can only imagine the atmosphere of excitement in the mission control room

Atmosphere of stress and nervousness too.

If you're tensed, what this

How do they land the mooncraft,by inputting manual commands or some automated command sequences?

All automated once command for landing is given.

@Alamarathan ji , it's automated command sequence .
@gslv markIII ji you too , the lander you sent to moon will land automatically.

 

[Swesh]

Chandrayaan-3 Mission: All set to initiate the Automatic Landing Sequence (ALS). Awaiting the arrival of Lander Module (LM) at the designated point, around 17:44 Hrs. IST.

Upon receiving the ALS command, the LM activates the throttleable engines for powered descent. The mission operations team will keep confirming the sequential execution of commands.

I know sh*t about satellite and stuff but I'm guessing this based on my knowledge about UAVs. Most of the modern UAVs and even some private jets nowadays have RTB or Return To Base (sometimes Home in civilian application) option. Once you press the autopilot will safely land you to one of its predetermined airstrips.

Manually you only have two commands; initiate and abort. After initiation the autopilot starts taking data from multiple (and redundant) sensors like radio altimeter, accelerometer, gyroscope, etc to do the landing.

Now I want to read our resident (all-in-one expert) Dhruv Thatti’s take on non-linear predictive control algorithm that will govern CY-3 lander’s automated landing on lunar surface.

Kon hai dhruv tatti jo dfi par vaas karta hai ,?
