So you're saying that I can construct a 3D topography of #Chandrayaan3 landing site and ShivShakti point or maybe see Vikram lander? we'll find out, soon enough 😉 CC: @gareebscientist @Akdixit131 @Ramanean

I've co-referenced the soft-landing images given by @CNSA_en to locate approximate landing site of #CE6 Chang'e 6. Approximate landing location is (-41.696660,206.006163). Base image is TMC2 image of #Chandrayaan2 at alt of 76.69 @5m resolution on 12th Dec, 2022. cc: @SegerYu

On Aug 23rd, 2023 @ 12:33 UTC India made a significant achievement of landing near Lunar South Pole. Before landing Dr.S Somanath, chairman of @isro said #Chandrayaan3 was designed with 6-sigma bounds - with a "Salvage mode" - "It will land no matter what" But how?! Lets find out

Heres more evidence that indeed that there was some of kind of deviations from the planned and actual orbits of #IM1 @Int_Machines I can't tell exactly how bad it is @coastal8049 this is what I can give you - how does these look like ? on-board: Semi-Major axis: 1837.46

Scott’s analysis indicate that the last minute changes could be potentially because they didn’t insert into needed orbit, hence the TC wouldn’t be needed and last min scramble to course correct to land at “intended” location which has nominal conditions per my terrain analysis
