Kudos, Isro scientists!

Fifteen minutes of anxiety-filled moments late last night.

Those were the 15 moments when scientists of Isro, the Indian Space Research Organisation, would make complex manoeuvres from their earth station in Bengaluru to guide Vikram, the unmanned, robotic lander, into making a soft landing on the south pole of the moon around 1.50 am -- a feat no one had achieved so far.

Three of my colleagues and I were glued to the live transmission.

1.35 am. Vikram began its descend and the scientists were reducing the speed progressively, in order to enable the soft landing of Vikram, the lander, on the moon.

Close to 1.50 am, everything seemed to be going perfectly well, just about a couple of minutes or so for the touchdown. Fingers crossed.

THE WORRY, THE SILENCE

But then as moments passed, the cheerful faces of scientists in the mission control room seemed to be filled with anxiety. There was silence, and an announcement came on the air that we were awaiting further updates.

We saw the chairman of Isro K Sivan walking up to Prime Minister Narendra Modi (who was at the tracking station in Bengaluru to witness the event). Moments later Modi got up and left the room after telling Sivam something and patting him on the back.

We got to hear that the communication from the lander had snapped. Many feared that either the lander had crashlanded because the speed of the descent couldn't be reduced to the required level or Vikram had landed but we hadn't got to know about it since the communication was off. 

Around 2.15 am, Sivan made an official announcement that the communication got snapped when the lander was 2.1 km from the surface of the moon and all the data are being analysed.

No one had yet said that the lander had crashed. But that was what it looked like.

SO NEAR YET SO FAR

Nevertheless, this was a mission that nearly succeeded. Only three nations -- the US, Russia and China -- have so far managed to land an unmanned craft on the moon. And that too after many failed attempts. The success rate of such efforts has been just around 40%.

No nation had landed a craft on the south pole, an area where scientists believe has minerals and water.

Yet, the fact that Indian scientists made this attempt and managed to get the lander as close to the moon as 2.1 km is indeed a great achievement.

The entire capsule called Chandrayaan 2 -- orbiter, the lander and the rover -- was launched on July 22.  On August 14, it left the Earth's orbit, and it entered the moon's orbit on August 20.

Meanwhile, the orbiter is still going around the moon and the payloads on it are working well.

SPACE EXPLORATION IS COMPLEX BUT VITAL

The Prime Minister was all praise for the scientists when he returned to the command centre this morning and spoke to them for nearly half an hour. "This was an experiment, and we make progress with experiments. We are with you," he said.

We will know in the coming days as to what exactly happened and why the lander couldn't make the soft landing as planned.

To say that failure is the stepping stone to success sounds a bit cliched. But that's a fact. No one has ever succeeded in doing, especially very complex tasks, without a few failures. And space is a complex and challenging area. Everything is remotely controlled.

Space explorations and the success of the scientific community the world over is what has given us many comforts -- from modern communication technologies to our ability to understand the climate patterns, helping us understand our earth better.
