600+ ISRO Related Full Forms (2024 Updated)

ISRO Related Full Forms

Last Updated: 28 November 2023

This article is written on ISRO-Related Full Forms to help students and anyone looking for Acronyms on the Internet but didn’t find the answer or Full Forms that didn’t have any relevance to ISRO.

Before we get into the list of ISRO Related Full Forms, let’s have a quick introduction to ISRO. The Indian Space Research Organisation is the national space agency of India, headquartered in Bangalore.

It operates under the Department of Space (DOS) which is directly overseen by the Prime Minister of India, while the Chairman of ISRO acts as the executive of DOS as well.

The Indian National Committee for Space Research (INCOSPAR) was established by Jawaharlal Nehru under the Department of Atomic Energy (DAE) in 1962, at the urging of scientist Vikram Sarabhai, who recognized the need for space research. INCOSPAR grew and became ISRO in 1969, within DAE.

Facts About ISRO

  • ISRO built India’s first satellite, Aryabhata, which was launched by the Soviet Union in 1975.
  • In 1980, ISRO launched satellite RS-1 onboard its own SLV-3, making India the sixth country to be capable of undertaking orbital launches.
  • ISRO has the world’s largest constellation of remote-sensing satellites and operates the GAGAN and NAVIC satellite navigation systems.
  • It has sent two missions to the Moon and one to Mars.
  • Aditya L1 is the first Indian dedicated mission to observe the sun, which is planned to be launched by the PSLV-XL launch vehicle.
