Chandrayaan 3 Moon delicate touchdown Pragyan Rover Vikram Lander 14 Earth Days
The Pragyan rover and Vikram lander collectively weigh practically 1,800 kg.
New Delhi:
Chandrayaan-3 has landed on the Moon after “20 minutes of terror” and the Vikram lander and Pragyan rover – carrying six scientific payloads between them – have one lunar day, or 14 Earth days, to collect sufficient knowledge to fulfill the curiosities of scientists internationally.
This deadline is important as a result of after a fortnight the solar-powered Pragyan rover – which made its mark on the Moon late final evening with ISRO declaring ‘India takes a stroll on the Moon’ – will decelerate as that is the extent of the ‘daylight cycle’ on the lunar floor.
How A lot Time Do Vikram, Pragyan Have On Moon?
Vikram and Pragyan could have 14 days solely earlier than evening falls on the Moon.
In different phrases, after 14 Earth days, the Moon could have an evening that can final one other 14 Earth days. Throughout this time the rover is probably not absolutely purposeful as there is no such thing as a solar energy and, extra importantly, evening temperatures can attain a harmful -208 levels Fahrenheit or – 133 levels Celsius and the rover, the lander and the payloads will possible have extreme hassle working.

Throughout this time, the rover might be contact with the lander and that can relay knowledge again to ISRO’s mission command centre. ISRO could have no direct hyperlink with the rover for this era.
The Touchdown Date
The legion of scientists on the Indian Area Analysis Organisation (ISRO) deliberate Chandrayaan-3’s touchdown date with the identical accuracy and precision that helped them land the 1,752 kg Vikram lander (with the Pragyan rover inside) practically 400,000 km from Earth.

August 23 was the beginning of 1 lunar day/evening cycle, which was why that date was picked because the touchdown date. If Vikram failed to the touch down on that day, ISRO had a back-up plan – land on August 24. If there was nonetheless no contact down (and the lander was undamaged), ISRO reportedly deliberate to strive once more 29 days later – after a full day/evening cycle on the moon.
Why The Lunar South Pole?
Chandrayaan-3 is particular as no different spacecraft has been capable of obtain a delicate touchdown close to the Moon’s South Pole. This space – removed from the equatorial area focused by different missions, together with NASA’s crewed Apollo landings – is filled with craters and deep trenches.
The findings from the Chandrayaan-3 mission might advance and develop data of lunar water ice, doubtlessly one of many moon’s most precious sources.
So What Occurs To The Lunar Modules After Mission Completion?
Neither the Vikram lander nor the Pragyan rover will return to Earth – regardless of what some Indian lawmakers could consider. And neither will the propulsion module that delivered them.

On completion of their respective experiments each the lander and rover will stay on the Moon. They won’t be purposeful in the course of the lunar evening and whereas there is no such thing as a plan to revive them after that interval, ISRO is hopeful each will survive the lengthy evening and begin up once more.
The Chandrayaan-3 Mission
The Rs 600 crore-Chandrayaan-3 mission was launched from the Satish Dhawan Area Centre in Andhra Pradesh’s Sriharikota on July 14, piggybacking on a Launch Automobile Mark-III (LVM-3) rocket. The journey to the Moon took 41 days and, considerably, was accomplished simply days after a Russian spacecraft trying the same consequence crashed after spinning uncontrolled.
