Chandrayaan-3 progressing well, moves into moon's 4th Orbit

 



ISRO has brought Chandrayaan-3 to the fourth orbit of the moon.  Now Chandrayaan is moving in an almost circular orbit of 150 km x 177 km.  ISRO had turned on the thrusters of Chandrayaan-3 at around quarter to twelve in the morning of 14 August.  The engines were switched on for about 18 minutes.


 On August 5, Chandrayaan-3 reached the first orbit of the moon.  After that its orbit has been changed twice.  On this day, Chandrayaan released the first pictures of the moon.  At that time Chandrayaan was traveling around the Moon in an elliptical orbit of 164 x 18074 KM at a speed of 1900 km per second.  Which was reduced to 170 x 4313 km orbit on 6 August 2023.  That is, it was put in the second orbit of the Moon.


 After this, on August 9, the orbit was changed for the third time.  Then it was moving in an orbit of 174 km x 1437 km from the lunar surface.  ISRO is getting the engines of Chandrayaan-3 retrofitted in the lunar orbit.  Means driving the vehicle in the opposite direction to slow down the speed.  After this, the fifth class will be changed between 8:38 am to 8:39 am on August 16.  That is, its engines will be turned on for only one minute.


 On August 17, the propulsion and lander modules of Chandrayaan-3 will separate.  On the same day, both the modules will be in a circular orbit of 100 km x 100 km around the Moon.  The lander module will be de-orbiting between 4.45 pm to 4.00 pm on August 18.  That is, the height of its orbit will be reduced.


 On August 20, the lander module of Chandrayaan-3 will be de-orbiting at 2.45 am.  On August 23, the lander will land near the south pole of the Moon.  If everything goes well, the lander will land on the surface of the moon around quarter past six.

 The health of Chandrayaan-3 is being continuously monitored from the Mission Operations Complex (MOX) of ISRO's Center Telemetry, Tracking and Command Network (ISTRAC) in Bengaluru.  At present, all the instruments of Chandrayaan-3 are working properly.
