Steps to be followed by Chandrayaan-3 Lander Vikram moments before moon landing

 


The wait is almost over.  Indian Space Research Organization's Chandrayaan-3 lander Vikram will float like a bird's feather on the moon's soil on Wednesday.  Through it, India is going to set foot on the south pole of the moon.



 ISRO has already announced that Vikram will land on the moon at 6:40 pm on Wednesday.  They tweeted on Tuesday that everything is going according to plan so far.  Vikram's movements are being monitored continuously.  ISRO is hopeful that Vikram is going to land on time.


 The lander Vikram has already separated from the main spacecraft.  It is currently floating 25 kilometers above the lunar surface.  The lander's height will be reduced in stages on Wednesday.  The speed of Vikram will decrease according to the balance with it.  It will take 15 minutes for Vikram to reach the moon from its current position.


 In the first phase, Vikram will be brought down to a height of 7.4 km.  At this time the speed of the lander will be 358 meters per second.  It will take 11 and a half minutes.


· The next destination is 6.8 km above the moon.  In this step, the speed of Bikram will be reduced further.  Then its speed will be 336 meters per second.


 · After this, the height of Vikram from the moon will decrease by 800 meters.  Then its speed will be reduced a little more.  At this stage, the lander will use laser beams.


 · Vikram will search for suitable land for landing by sending a laser beam on the moon's soil through sensors.  After that the height will be reduced gradually.


 · Bikram will have a speed of 60 meters per second on the way down from a height of 800 to 150 meters.  After that, during descent from 150 to 60 meters, this speed will be 40 meters per second.


 · Bikram will have a speed of 10 meters per second while falling from 60 to 10 meters.  After that, the lander will make a soft landing on the moon.  At the last moment its velocity will be 1.68 m/s.


 This last stage of landing is considered to be the most difficult and important.  Four years ago, India's dream of touching the moon remained here.  Chandrayaan-2 failed.  This time, however, ISRO has prepared in advance keeping in mind all possibilities.  Special sensors are installed in Vikram.  There are many cameras.  ISRO claims that Vikram will land on the moon even if the sensors stop working.  That's how the lander is designed.


The whole of India is now waiting with fingers crossed  come 23 August
