#Chandrayaan3 's near precision landing! Difference between the Actual & Targeted landing site is ~358m.. Hats off the ISRO Engineers who were able to achieve it despite all the obstacles on Moon! It's important to have these kind of precision landings for any future mission!

#AdityaL1mission & Lagrange points: In "simple words", Lagrange points are points between any 2 gravitational bodies that can be called as "parking spots" where a satellite can neither be attracted or repulsed by 2 bodies (Here L1,L2,L3,L4 and L5 are Lagrange points) (1/5)

#Luna25 Update: 1. According to rumors, during transition to pre-landing orbit, impulse was given 2. Impulse exceeded 1.5 times than the expected burn 3. Most probably it might have crashed on Moon as the contact was lost and has not been regained even after 16 hrs! (1/n)

South Pole region is not always well lit and the lander was in a shallow depth of 2 ms from the surface so it was not visible in Nov 11th's NASA flyby due to different angle of incidence & would be difficult for anyone to find it unless the sun is directly above the surface(3/4)
