Science and its Fact

Cool facts about Vikram Lander and Pragyan Rover that you never know

Chadrayan 2 is India’s second spacecraft to fulfill the moon mission. After passing the stage 2 and when it was just 15 minutes away from its final destination, the whole world was sitting fingers crossed for the Chandrayaan 2’s landing. The moon mission chandrayan 2 has several crucial phases and challenges. Though we might have missed the taste of success in just a few meters we take pride to have attempted things that were not done by any other country in the world.

Why the rover can function only for 14 days?

Before diving into the actual topic you should understand some basic facts about the moon.

The circumference of the earth is 40,075 KM and the rotation speed is 1674 kmph hence it takes 23.939 hours(40075 divided by 1674)

Now if we consider the same for the Moon

The circumference of the earth is 10,921 KM and the rotation speed is 0.004627km  per second hence it takes 2,360,276.637 seconds (10921 divided by 0.004627)  which is 656 hours /27.32 days.

By considering the above facts, we should understand that 1 day on earth is equal to 28 days in the moon.  As per the reports stated by ISRO, the rover receives its operating power from solar energy which can be obtained only in the day time. Nighttime in the moon is extremely cold which reaches up to 180 degrees.  Our scientists have designed the lifespan of the rover according to the day time which is 14 days in the moon.

Here are some of the coolest things about chandrayan 2

Geosynchronous Launch Vehicle Mark-III spacecraft of chandrayan 2 is the powerful launcher that is completely designed in India. It has three modules – the Orbiter, the Rover (Pragyan), the Lander (Vikram).

The Lander has the advanced propulsion systems to endeavor the first soft landing on the Moon.

The orbiter of Chandrayaan 2, Lander and rover will take 14 scientific payloads that include the X-ray Monitors, Laser-induced breakdown spectroscopes. These will help the mission to understand the composition and seismic activities of the moon in a better way.

The technical challenges of the Moon’s South Polar Region landing have deterred several previous space attempts.  Chandrayaan 2 is the first-ever spacecraft to reach the South polar region of the moon surface and had carried the Indian tricolor to the part where no other country has touched before.
