Indian American astronaut Sunita Williams inspired the youth in India to take up career in space, she holds the world record for the longest spaceflight by a female astronaut.
Addressing a gathering of students and teachers at the National Science Centre here, Williams told the youth to follow their dreams despite failures.
Williams said that it is important to inspire the young to take up research in science, maths and technology.
Williams lauded the Chinese space programme commending them on their efforts and progress made by them.
"Well, I will make one comment about the Chinese, we are very happy for them, and its pretty amazing the things that they have done. That they are able to launch people into space, have a space station, do a space walk, have a first woman into space so congratulations to the Tigernauts and the Chinese space program its pretty impressive so we are very excited for them," said Williams.
" I think anybody who is a space traveller is rooting for your space compatriots to be successful and to have a safe flight," she added.
Williams, who began her India trip today, will next fly to Mumbai and spend Wednesday and Thursday in the financial capital, before going to Gujarat.
In Mumbai, the astronaut is scheduled to visit a working women's hostel managed by the Indian Council of Social Welfare in Chembur and talk to residents and students.
