The moon boasts a faint ambiance. By touchdown and analysing the air, we will unravel extra of the moon’s mysteries, says Somak Raychaudhury, an eminent astrophysicist presently serving as Vice-Chancellor at Ashoka College. He provides {that a} driving drive behind these endeavours is the anticipation of building lunar colonies for future area exploration. The moon might function a vital waypoint on our journey to Mars and past.
Professor Raychaudhri, beforehand the Director of the Inter-College Centre for Astronomy and Astrophysics (IUCAA), Pune, joined us to debate the significance of the Chandrayaan 3 mission because it prepares for a gentle touchdown. This is an edited excerpt from the interview.
What particular outcomes is India aiming for with the Chandrayaan mission?
Though India’s area exploration started later than America’s moon and planetary missions, ISRO initially targeting Earth-related tasks akin to local weather, climate, communication, satellites, and distant sensing. With lunar missions now underway, we intention to showcase our capabilities and international management in pushing technological boundaries.
Why is the moon so vital to us?
The moon and Earth shaped across the identical time, roughly 4.5 billion years in the past. Though they originated from the identical materials, their fluid states throughout formation led them to solidify with distinct buildings. Notably, sure options current on Earth’s floor additionally exist deep throughout the moon, and vice versa. Due to this fact, learning the moon can present insights into our personal planet’s historical past.
Why are we concentrating on the moon’s southern pole as Chandrayaan 3’s touchdown website?
Earlier missions primarily explored the moon’s northern hemisphere, however evaluating it to exploring Africa versus Europe underscores the variations.
We have now already unequivocally confirmed the presence of water on the moon. This information stems from analyzing the spectrum of sunshine emitted by the moon. One suspicion is that water could also be concentrated within the moon’s southern hemisphere, the place elevated mountains, deep craters, and in depth shaded areas reside, devoid of daylight and with temperatures as little as -200 levels.
Why has the lunar exploration programme gained sudden momentum?
Our understanding of the photo voltaic system and the moon has expanded considerably for the reason that Nineteen Sixties and 70s.
Technological progress, together with quicker knowledge transmission charges and superior computing, together with miniaturization, has revolutionized area exploration, rendering it more cost effective. The participation of personal entities, together with notable figures like Elon Musk, has catalyzed bold undertakings.

Whereas Luna 25, the Russian lunar spacecraft, reached moon orbit in simply ten days as a consequence of a robust rocket, Chandrayaan 3’s journey spanned over a month. Is there a must broaden past the scope of frugal engineering?
I consider India has chosen a extra managed and fewer dangerous path to the moon. Studying from the previous crash, meticulous orbit design and parameter issues have been prioritized.
The continued Gaganyaan mission for human lunar exploration underscores the paramount significance of security.
ISRO has devised particular methods for these missions. The company has transitioned from being a extremely insular group to actively in search of recommendation from a broader array of consultants.
