India on the Moon, over the moon

Goosebumps and moist eyes. I couldn't contain my excitement as the lander Vikram steadied itself to the right position, decelerated from 1 km per second to near zero, and then touched down near the south pole of the Moon, exactly at 6.03 pm today.

That's a place on the lunar surface where no spacecraft has ever landed. 

As scores of ecstatic scientists broke out into applause, the enormity of their collective achievement was only sinking in.

Vikram touches down on the Moon.

This is no mean achievement. One, remotely landing a craft on the Moon is more difficult than getting it to just go around the Moon. Two, the southern areas of the lunar surface are uneven with boulders and crevices. 

The failure of Chandrayaan-2 in 2019 when scientists lost contact with the lander seemed like a bad dream in the distant past. I had blogged about it here

(The most critical moments in the above transmission are from 38 minutes to 45 minutes)

There was a quiet race to the south of the Moon because it's believed that there are water molecules (in a solid state) there.

Over the next 14 days, Indian scientists will be studying data relayed by the rover, Pragyan (the Sanskrit word for knowledge). 

India is part of the 28-nation Artemis team. The probes by Pragyan will be beneficial to space scientists across the world in their relentless quest for knowledge and to look beyond the obvious. 

This huge lunar leap will also boost interest in science in general, and astrophysics and related subjects in particular, among students.

  7. Great achievement. However, I wonder if all the water on earth is insufficient that they need to go and find it on the moon..

    1. Hi Rajesh - Quite possibly, the water on Moon isn't going to be same as on Earth!

  8. Hi Pradeep - it certainly is a huge achievement by India - and good to see they're sharing their data etc ... where is the south side of the moon - for that matter where is our south pole??!! Is it further from the sun, than our north pole ... I'd never really wondered before ... now??!! I'm looking forward to reading what they find out ...

    Cheers - great to see this post ... Hilary

    1. The best way to understand the poles is by looking at a globe. The portion at the top is the north pole and the one at the bottom is the south. I presume it's the same for the Moon. Yes, all are eagerly waiting to see the data that the rover (named Pragyan) will send back to Earth.

  10. When I heard this good news, one of the songs by Tamil Poet Kannadasan immediately came to my mind. Will translate the first 4 lines in English:

    That’s when the question was born
    Got a good response today
    That’s when the desire was born
    Everything happened today

  13. A great feat by the scientists. India should stop politicising such historic achievements, however.

  14. I don't know why I teared up when at touchdown, it was so overwhelming. I am so proud of ISRO and excited to see what's more to come.
