The Chandrayaan-2 spacecraft is expected to reach the moon's orbit on August 20 and land on lunar surface on September 7.
ISRO chairman K Sivan said the proposed soft-landing was going to be a 'terrifying' moment.
Other than the Cartosat-2 series satellite, the PSLV is carrying 29 nano satellites from 14 countries - Austria, Belgium, Chile, Czech Republic, Finland, France, Germany, Italy, Japan, Latvia, Lithuania, Slovakia, the United Kingdom and the United States of America besides a nano satellite from India.
Having reached the Red Planet, ISRO can now focus on getting humans in space and secure the resources to do it
'When you look at it from the point of view of science, Chandrayaan 2 is a big success.'
