Chandrayaan-3’s Moon touchdown in 3 days: ISRO’s Vikram lander’s journey up to now


Chandrayaan-3, India’s third lunar mission, is all set to make its first soft-landing try on the Moon in three days. On Sunday morning, the second and last deboosting operation of the mission was carried out efficiently, the Indian House Analysis Organisation (ISRO) knowledgeable. Publish this, the module will likely be present process inner checks, and the powered descent is anticipated to begin on August 23.

“The second and last deboosting operation has efficiently diminished the LM orbit to 25 km x 134 km. The module would bear inner checks and await the sun-rise on the designated touchdown website. The powered descent is anticipated to begin on August 23, 2023, round 1745 Hrs. IST,” the ISRO wrote on X, previously generally known as Twitter.

Chandrayaan-3’s journey up to now:

July 6: The ISRO declared Chandrayaan-3 mission would launch on July 14 from Andhra Pradesh’s Sriharikota’s second launch pad.

July 7: All automobile electrical exams had been accomplished efficiently.

July 11: A 24-hour ‘Launch Rehearsal’ was executed efficiently.

July 14: ISRO’s LVM3 M4 launched Chandrayaan-3 into its meant orbit.

July 15: The mission’s first orbit-raising manoeuvre succeeded in Bengaluru. The spacecraft reached an orbit of 41762 km x 173 km.

July 17: The second orbit-raising manoeuvre put Chandrayaan-3 in an orbit of 41603 km x 226 km.

July 22: The fourth orbit-raising manoeuvre, Earth-bound perigee firing, efficiently positioned the spacecraft in a 71351 km x 233 km orbit.

July 25: One other orbit-raising manoeuvre was carried out efficiently.

August 1: In a big milestone, Chandrayaan-3 entered the translunar orbit with an orbit of 288 km x 369328 km.

August 5: The spacecraft entered the lunar orbit at 164 km x 18074 km.

August 6: The spacecraft’s orbit was lowered to 170 km x 4,313 km across the Moon.

August 9: One other manoeuver was carried out that lowered the spacecraft to 174 km x 1437 km.

August 14: The mission entered the orbit circularisation part of 151 km x 179 km orbit.

August 16: The spacecraft entered the orbit of 153 km x 163 km after the firing.

August 17: The touchdown module, comprising the Vikram lander and Pragyan rover was separated from its propulsion system.

August 18: The spacecraft efficiently accomplished a ‘deboosting’ operation that diminished its orbit to 113 km x 157 km. Deboosting is the method of slowing all the way down to place itself in an orbit the place the orbit’s closest level to the Moon (Perilune) is 30 km and the farthest level (the Apolune) is 100 km.

August 20: Chandrayaan-3 carried out the second and last deboosting operation and diminished the LM orbit to 25 km x 134 km.

August 23: If all the pieces goes nicely and as deliberate, the spacecraft will land on the lunar floor.
