Hello Aspirant,

Indian Space Research Organization has about 8,000 scientists working in different branches of ISRO. Indian Space Scientist Mr. K Sivan is now serving as the chairperson of ISRO. Name list of all scientists of ISRO is not supposed to be disclosed Publically by ISRO because it is very confidential information and they do not disclose it due to security reasons.

I hope this information helps you.

Good Luck!!
