How to become a Space Scientist in India
अंतरिक्ष वैज्ञानिक
Build and use satellites, rockets and instruments to explore space and serve life on earth.
- Streams
- Science (PCM)
- Time it takes
- 4–5 years after Class 12 for engineering roles; research science roles usually need a PhD
- Key exams
- JEE Main, JEE Advanced, IISER Aptitude Test
What you actually do
- Design, test or operate spacecraft, payloads and launch vehicles
- Analyse data from satellites and space missions
- Work on applications such as weather, navigation and remote sensing
A day in the life
Reviewing test results for a satellite subsystem, a design review with other teams, writing analysis code for mission data, and documenting everything for the next stage.
The path, step by step
- Class 9–10: strong maths and physics; join astronomy or robotics clubsabout 2 yr
- Class 11–12: Science with PCMabout 2 yr
- Entrance: JEE Main/Advanced (IIST and IITs), IISER Aptitude Test or NEST for science routesabout 6 mo
- B.Tech (Aerospace, Electronics, Mechanical, CS) or BS-MS/M.Sc Physics (4–5 years)about 4 yr
- Optional: M.Tech/PhD; prepare for ISRO Centralised Recruitment Board noticesabout 1 yr
- First job: Scientist/Engineer SC at ISRO, or researcher at PRL or another space science lababout 1 yr
