SULPHUR ON MOON

The Indian Space Research Organisation (ISRO) has confirmed the presence of sulphur and otherchemical elements on the lunar surface near the south pole, as expected. This confirmation was madeby the instruments aboard the Pragyan rover of the Chandrayaan-3 mission.

Sulphur is a relatively rare element on the Moon. Its presence in the south pole region is significant

because it could be a sign of the presence of water ice. Water ice is thought to be trapped in the permanently shadowed craters of the south pole region.

SUCCESSFUL CHANDRAYAAN - 3 HISTORIC MOON MISSION

                            



                              சாதித்தது இந்தியா! - நிலவில் கால் பதித்து சரித்திரம் படைத்தது சந்திரயான் 3

பூமிக்கும் நிலவுக்கும் விஸ்வரூபம் எடுத்து நிற்கிறது இந்தியா
ரஷ்யா அமெரிக்கா சீனா என்ற வரிசையில் இனி இந்தியாவை எழுதாமல் கடக்க முடியாது
இஸ்ரோ விஞ்ஞானிகளின் கைகளைத் தொட்டுக் கண்களில் ஒற்றிக்கொள்கிறோம்
இது மானுட வெற்றி
அந்த நிலாவத்தான் நாம கையில புடிச்சோம் இந்த லோகத்துக்காக
இது போதாது நிலா வெறும் துணைக்கோள் நாம் வெற்றி பெற - ஒரு விண்ணுலகமே இருக்கிறது

THE SECRET OF MOON ON THE HEAD OF SIVA

According to the science, it takes about 27.3 days for moon to complete the revolution around earth.

During which new moon has to pass through various phases and again forms a new moon.

(HINDU ANALOGY)

There is a tale where 27 daughters of Daksha Prajapati, marry Chandra Dev. But Chandra Dev only loves one and ignores 26 others. This makes Daksha angry and he curses moon to fade away as he was proud of his brightness.

Chandra Dev then requests Lord Shiva to help him, and then Shiva and Daksha argue over the fading of moon, finally Lord Vishnu settles debate by saying Lord Shiva taking moon over his head and taking responsibility to keep half moon shining, while Daksha keeping half moon fading.

In this tale, 27 daughters of Daksha; is a metaphor for explaining that moon has more than 27 phases.

  • Moon loving only one: is a metaphor for fact that full moon is the condition when moon is completely visible.
  • Distributing moon to half by Vishnu: is a metaphor that represents moon will be getting bright in one phase and it will be getting fade in other.
  • Shiva holding moon on head: is metaphor for first 15 phases for which moon is bright.
  • Daksha causing moon to fade: is a metaphor for next 15 phases for which moon is fading.

Long before our Scientists today, ancient people had told us about revolution and phases of moon.

CHANDRAYAN 3

Why is Chandrayaan 3 orbiting the Earth instead of orbiting the Moon?

The Chandrayaan-3 mission, with a budget of only ₹615 crores, has adopted a clever strategy to reach the Moon in a cost-effective manner. Instead of using a powerful rocket for a direct journey, ISRO is utilizing the gravitational slingshot effect to enter the Moon's orbit with the help of Earth's gravity.

This approach involves leveraging the gravitational force of Earth to generate a powerful push, propelling Chandrayaan-3 closer and closer to the lunar orbit. During each perigee (the closest point to Earth) in its orbit, the spacecraft's engines are fired to increase its speed, resulting in a higher and more elongated orbit. By repeating this process strategically, the spacecraft gains the necessary momentum to enter the lunar orbit.

Once Chandrayaan-3 successfully enters the lunar orbit, it will commence several orbits around the Moon before proceeding with its intended mission, including a planned landing at the designated location.

By employing this innovative approach, ISRO has managed to overcome budget constraints while still enabling Chandrayaan-3 to accomplish its mission goals effectively.

Through boundless space, our missions roam, seeking truths yet to be known.

With stars above and dreams in flight, we journey onward, towards Infinite.
