The Entire World Is Glued As Chandrayaan 3 Prepares For A Soft Landing

The entire world is glued as Chandrayaan 3 prepares for a soft landing. Millions of people across the country are praying as time is ticking for India's Chandrayaan 3 soft landing. Now all the countries including Russia, China, and America are waiting eagerly for India's Chandrayaan 3, and people are keeping their fingers crossed as Chandrayaan 3 is preparing for a soft landing.

The people of India were disappointed when Chandrayaan 2 failed at the last minute in 2019 when the lander deviated from its intended trajectory while attempting to land at just 2.1 KM altitude from the moon. However within four years, the scientists of ISRO reached the final stages of the mission to the Moon and if Chandrayaan 3 soft landing turns out to be successful, India will become only the fourth nation to land on Moon after Russia, China, USA and it will be the first nation to land on the south of the moon.

The mission starts at 5.45 PM and ISRO made all the arrangements and all the national and international channels will be airing the event live. Even NASA is airing the event live from 5.15 PM. But the entire process starting from 5.45 PM is known as 15 minutes of terror.

Former ISO scientists shared that the entire process is 15 minutes of terror. There are different phases in descent and they are initial preparation, velocity reduction, orientation change, attitude hold phase, fine braking, final descent, and touchdown, They are explained by the ISRO scientists in the following way.

The crucial moments during the last 15 minutes before touchdown encapsulate intricate maneuvers, intense calculations, and an unwavering commitment to exploring the Moon's mysteries,"

The initial preparation phase comprises the final 1,139 seconds of the Chandrayaan-3 mission, and it is during this stage that the most critical operations will be performed.

"When the final descent begins, the Vikram lander will be positioned about 750 kilometres from the landing site, will soar 25 to 30 kilometres above the lunar surface, and race at a velocity of about 1,600 metres per second horizontally,"

The next phase, which is velocity reduction, will last 690 seconds, and thrusters will be fired to reduce Vikram's velocity to one-fourth of its initial speed, "With this controlled slowdown and the Moon's gravitational pull, the Vikram lander will start descending vertically at around 60 metres per second."

The orientation change phase will take place simultaneously with the velocity reduction stage. During the orientation change phase, the lander will be slightly rotated, and a crucial calibration will be conducted 32 kilometres from the landing site, and 7.5 kilometres above the ground, Purohit explained.

The attitude hold phase is a sensitive stage, and will last 10 seconds "It will check the terrain and confirm the landing spot, avoiding the complications that caused Chandrayaan-2 to crash on the Moon."

During the critical fine braking phase, Vikram will be aligned vertically, and will hover at a height of 800 to 1,300 metres above the landing site,. "Cameras and sensors will be activated, the computer onboard the spacecraft will process information and decisions about landing will be finalised."

The final descent phase is the one in which the Vikram lander will hover above the lunar surface at a distance of around 150 metres. "The hazard detection camera's 'Go/No-Go' checks will guide the final decision. If all is well, Vikram will commit to the 73-second descent that will mark its historic touchdown,"

Cinejosh team wishes ISRO scientists all the best and a smooth landing of the Chandrayan 3 lander and wishes India create history and becomes the first nation to land on the south side of the moon.
