I am Yajur Kumar, and I love explaining rocket science like it is not the rocket science. I work as GNC and AOCS Engineer at the national space agency of India (ISRO). I have worked on several projects like Chandrayaan-2, Chandrayaan-3, Aditya-L1, GSAT-31 and many more. I am responsible for designing that logic of the computer brain which controls the moods of the spacecraft in the orbit, tell it where it has to go, where is it right now, and how should it approach the path, and meanwhile when the satellite starts behaving like a drunk man, I design the control system that controls its steps and keeps a check on its 'attitude'.

My Story

I am a space enthusiast, engineer, thinker and on the top, I want people to understand what I do in the most simple terms. I graduated from IIT Kanpur in Aerospace Engineering, where I focused on Flight Mechanics and Controls. I loved the dance of satellites and spacecraft in the orbit and in the deep space, so my thesis was on the topic of 'Relative Orbital Motion in the Orbit'.

If you want to talk about deep space missions, control system engineering related to that, you can count me in. You can connect with me over LinkedIn at

Keep exploring and keep looking up!


I'm always looking for new and exciting opportunities and discussions. Let's connect.
