One thing that is still alive on Chandrayaan 3:
Chandrayaan :
Introduction:
India's Chandrayaan 3 mission which successfully landed near the South Pole of the Moon for 2 weeks on August 23 and completed all its mission targets. And at this place on the moon after 2 weeks after sunrise it was hoped that it would rise but it didn't but did you know that there is something on this Vikram lander that is supposed to complete the mission.
LRA is still working on Chandrayaan-3
" Laser Retroreflector Array (LRA)"
It was a gift from NASA to the Indian Space Agency. The Vikram Lander had 4 instruments, one of which was the LRA. The function of this reflector is to reflect the laser light, that is, with the help of the Orbiter laser rays around the moon, by using this reflector, the actual location of the lander on the surface of the moon, the distance from the earth to the moon (Laser Ranging) and so on. A location map of the lunar surface will be created using all the reflectors.
With the help of Altimeter or LiDar installed on the orbiter around the moon, it can be measured with high accuracy by shining a laser light on this 5 cm diameter reflector from a distance of a few hundred kilometers. So far this type of altimeter is installed on NASA's Lunar Reconnaissance Orbiter.
