Big achievement

Sir — This refers to the achievement of our brilliant space scientists of the Indian Space Research Organisation regarding the Mars mission. I congratulate the team of 200 scientists led by Mr S Arunan, who hails from a middle-class family. 

We, with 65 per cent of population at 35 years of age and less, can take India far, as Prime Minister Narendra Modi said at Madison Square Garden on September 28. These talented scientists needed no incentive but they enjoyed their work by treating it as an expression of freedom.
