ISRO changed class 5th time to Chandrayaan-2, just 31 days away from the moon


ISRO changed class 5th time to Chandrayaan-2, just 31 days away from the moon: Scientists of Indian Space Research Organization (ISRO) are continuously advancing their second moon mission Chandrayaan-2 from the Earth’s orbit. After its launch on 22 July, it was set at Periji (less distance from Earth) 170 km and Apoji (more distance from Earth) at 45,475 km. Today i.e. on August 6, between 2.30 pm and 3.30 pm, Chandrayaan-2 successfully made a fifth change in the class. Now its perigee has been increased to 276 km and apogee 142,975 km. Now after this, a trans lunar insertion of Chandrayaan-2 will be done between 3 to 4 am on August 15. That is, Chandrayaan-2 will be put in a long orbit going towards the moon.

Since its launch on July 22, the 48-day journey of Chandrayaan-2 to reach the south pole of the moon has started. 16.23 minutes after launching, Chandrayaan-2 was orbiting Earth’s orbit at a height of about 170 km from the Earth, separated by a GSLV-MK3 rocket. ISRO scientists had made many changes regarding the launch of Chandrayaan-2.

Changes made to Chandrayaan-2’s orbits earlier

  • On August 2, at 3:27 pm, the perigee of Chandrayaan-2 has been increased to 277 km and Apogee 89,472 km.
  • On 29 July between 2.30 and 3.30, the duration of Chandrayaan-2 was 276 km and Apogee was 71,792 km.
  • At 1.08 pm on July 25-26, the perigee of Chandrayaan-2 was increased to 251 km and Apoge 54,829 km.
  • On July 24 afternoon, at 2.52 pm, the perigee was done 230 km and Epogee 45,163 km.

Various stages of 48-day journey of Chandrayaan-2

Chandrayaan-2 space shuttle will travel around the earth from 22 July to 6 August. After that, from 14th August to 20th August, you will travel in the long walk to the moon. On August 20, it will reach the orbit of the moon. After this, for 11 days i.e. 31 August, he will revolve around the moon. Then, on 1 September, Vikram will break away from the lander orbiter and start the journey towards the south pole of the moon. After a 5-day journey, on September 6, the Vikram lander will land on the south pole of the moon. About 4 hours after landing, the rover will come out of the Pragya lander to perform various experiments on the lunar surface.

Know … What was the difference between the launching of 15 July and the launching of 22 July

  1. The time to go to Earth Orbit has been extended by about one minute

July 22: Chandrayaan-2 will now reach an altitude of 181.65 km from Earth in 974.30 seconds (about 16.23 minutes).

July 15: Chandrayaan-2 was to go 181.61 km from the earth in 973.70 seconds (about 16.22 minutes).

2. Changes in the elliptical circle around the Earth, 60.4 km difference in Epogee

July 22: Chandrayaan-2 will revolve around the Earth in an elliptical orbit. Its perigee (less distance from earth) will be 170 km and apogee (more distance from earth) will be 39120 km.

July 15: Chandrayaan-2 would have launched 170.06 km and apogee 39059.60 km if launched. That is, a difference of 60.4 km has been brought to Aposhi. That is, the movement around the earth will be reduced.

3. A 6-day reduction in the time of Chandrayaan-2 going to the moon

If Chandrayaan-2 was launched successfully on 15 July, it would land on the south pole of the moon on 6 September. But after today’s launching, Chandrayaan-2 will take 48 days to reach the moon. That is, Chandrayaan-2 will reach the moon on September 6. For this, ISRO scientist Chandrayaan-2 will be cut in the circle around the Earth. Probably Chandrayaan-2 made four revolutions around the earth instead of 5.

4. Chandrayaan-2’s velocity increased by 1.12 meters per second

Chandrayaan-2, after its launch on July 22, will now go towards the moon much faster. Now its speed in space will be 10305.78 meters per second. Whereas, if launched on July 15, it would go towards the moon at a speed of 10,304.66 meters per second. I.e. its speed has increased by 1.12 meters per second.
