The Indian Space Research Organization (ISRO) is one of the world’s leading space agencies, known for its impressive achievements in space exploration, cost-effective missions, and advanced technology. Indians take immense pride in the endeavors taken up by ISRO, which has successfully completed many missions while constantly pushing the boundaries of space science.

If you’re inspired by ISRO’s work and want to become a part of it, a career as a space scientist could be your calling. In this blog, we’ll cover everything you need to know to embark on this journey—from educational qualifications to the courses and colleges that can help you get there.
Who is a Space Scientist?
Space scientists are generally divided into two categories: Physicists and Astronomers. Physicists focus on theoretical concepts and laboratory work, while astronomers conduct research on galaxies, stars, and other celestial phenomena. Both paths lead to a career in space science, which is the study and exploration of the universe.
How to Become a Space Scientist at ISRO?
Here’s a detailed, step-by-step guide on how to become a space scientist at ISRO:
Step 1: Complete 10+2 with Science
To start on the path to becoming a space scientist, you need to complete your higher secondary education (10+2) with Physics, Mathematics, and Chemistry as compulsory subjects. You should have a strong grasp of mathematical and physical concepts.
Step 2: Pursue an Engineering Degree
After completing 12th grade, the next step is to pursue a B.Tech or B.E. degree in fields such as:
- Mechanical Engineering
- Electronics Engineering
- Electrical Engineering
- Aerospace Engineering
- Computer Science Engineering
- Engineering Physics
- Radio Engineering
These fields provide the foundation required for space science careers.
Step 3: Appear for ISRO’s ICRB Exam
After obtaining a B.E. or B.Tech degree, candidates must clear the ISRO Centralized Recruitment Board (ICRB) exam. The eligibility criteria for this exam are a minimum of 65% marks (or a 6.8 CGPA on a scale of 10) in the qualifying degree. The ICRB exam consists of a written test followed by an interview.
Students may also pursue higher education such as a Master’s or PhD in fields like Geophysics, Geoinformatics, Applied Mathematics, or Instrumentation before applying for the ISRO exam.
Courses to Pursue After 12th for a Career in Space Science
Here are some recommended courses after 12th grade for those aspiring to become space scientists:
- B.Tech in Aerospace Engineering
- B.Tech in Avionics Engineering
- M.Tech in Electronics, Electrical, Mechanical, or Computer Science
- PhD in Physics or Astronomy
- PhD in Aerospace Engineering
- B.Tech in Engineering Physics + M.S. in Astronomy or Optical Engineering
These courses will equip you with the skills and knowledge required to excel in the field of space science.
