Bengaluru: About 10 years after the launch of the India’s first lunar mission, Chandrayaan 1, Indian Space Research Organisation (ISRO) scientists recall the nail-biting experience. This comes in the wake of Chandrayaan 2's 'Vikram' lander on the Moon in the early hours of Saturday. 

On the day of the Chandrayaan-1's launch in 2008, the ISRO faced a "very tough situation" as it had a very short launch window and the weather was "very, very bad", Dr. M Annadurai, Project Director of the successful mission, said.

"We were running against time, that was the last date to take off, we had some technical issues to set right and the weather was very, very bad at Sriharikota spaceport. Everybody was anxious, luckily for half-hour, weather cleared but after that there were thunder-storms; launch time was a real nail-biting moment", Dr Annadurai, also the Programme Director of the 'Mangalyaan Mission' (Mars Orbiter Mission), launched in 2013, said.

Now Chairman of the National Design and Research Forum, he termed the present Chandrayaan 2 mission, which seeks to make soft-landing of Vikram on the unexplored Lunar south pole, as another milestone in India's space journey.

"...whatever we started is getting carried forward, another milestone for Indian space journey, we are not falling behind, we are taking the lead and going ahead in the international arena. That way, it's a satisfying moment", Annadurai said.

He said missions such as Chandrayaan 1, Chandrayaan 2 and Mangalyaan were also aimed at enthusing the young generation to pursue basic science and further develop Indian aerospace industry.

The success of such missions enhanced India's reputation in managing them and makes its case in any future collaborative planetary ventures much better in the international arena, the scientist added.

Chandrayaan 1 scripted history by making more than 3,400 orbits around the Moon and was operational for 312 days till August 29, 2009.

According to ISRO, the mission conclusively established traces of water on the moon, making a path-breaking discovery.

Chandrayaan 1 also discovered water ice in the North polar region besides detecting magnesium, aluminium and silicon on the lunar surface while global imaging of the moon was another achievement of the mission.
