CHANDRAYAN 3 (C3)

23 AUGUST 5.32 PM

15 minutes of Hitchcock suspense.

8 stages

 1. STAGE1: Descend from 30kms to 7.4 kms height: Elliptical orbit. 100kms at the farther extreme to 30 kms in the closer end. On August 23 rd, C3 commences its downward movement from 30 kms height. Speed of the rocket reduced to 1200KMPH from 6000KMPH during the descend to 7.4 kms height. Total time taken: 10 minutes.

 2. STAGE2: Descend from 7.4 Kms to 6.8 kms in height: Two important maneuvers executed: A).Tilting of C3 to 59degrees inclination. 😎. To take the decision of landing at the desired location by a device similar to facial recognition to open I phone. Photo of desirable spot is fed.

 3. STAGE3: Descend from 6.8 Kms to 800 meters in height: First maneuver is to straighten the legs from 59 degrees inclination to near vertical. Second action is taken by the rockets to reduce the speed of the C3 to nought @ 800 meters height from the original 1200KMPH.

 4. STAGE4: Descend from 800 meters to 150 meters: At 150 meters height , C3 suspends itself in the moons gravity without any motion! Now it scrutinizes the obstruction free path to reach the selected spot to land.

 5. STAGE5: Descend from 150 meters & 60 meters in height: This descend is gradual fall towards the preselected location.

 6. STAGE6: Descend from 800 meters to 150 meters & 10meters in height:: This descend is akin to a falling feather.Here ISRO, from the C2 experience of bad landing, has taken measures to prevent the same by incorporating a camera to register the speed of approach to lunar surface and control the speed of the C3 rocket.

 7. STAGE7: Free fall from 10 meters height to Lunar surface: At this stage, C3 is allowed to free drop like a stone. After the fall, no action is taken for next three hours to ensure the dust settles down and be ready for the Stage 8 maneuver.
