Aryaans Institute successfully organized an online guest lecture on 4th January 2026. The session was delivered by Dr. Bhanu Pant Visiting Professor at IIT Roorkee and former Outstanding Scientist and Group Director at ISRO Vikram Sarabhai Space Centre with nearly four decades of experience as a scientist at ISRO.
The lecture provided a detailed understanding of India’s space program and the scientific principles involved in space technology. Dr. Pant began by explaining what space is in simple and clear terms and further elaborated on how rockets are able to overcome gravity and function as launch devices. He explained important performance parameters such as thrust specific impulse and velocity gain which are essential in determining rocket efficiency.
The session included an in depth explanation of various launch vehicles such as SLV ASLV PSLV and GSLV. Dr. Pant explained the structure and working of PSLV and GSLV in high detail using visual representations which helped the participants clearly understand their design and functioning. He also spoke about sounding rockets their small payload capacity and their role within the Earth’s atmosphere.
Dr. Pant discussed important space missions such as Chandrayaan and Aditya L1 and explained the concept of atmospheric re entry in the context of future missions. He also spoke about upcoming projects and what lies ahead for ISRO highlighting the organization’s future direction. The lecture highlighted key factors behind ISRO’s success including strong vision focused mission planning disciplined execution early technology development rigorous quality standards and long term strategic thinking. He also explained ISRO’s Golden Circle principle focusing on why mission goals how mission definition and what mission execution.
The session further covered rocket structure spacecraft structure and different types of spacecraft including navigation science and communication satellites. Dr. Pant emphasized the role of satellites in disaster management telemedicine traffic management broadcasting maritime affairs communication and remote sensing demonstrating how space technology contributes directly to societal development.
Towards the conclusion of the lecture Dr. Pant also highlighted various opportunities available for students at ISRO and explained different programs internships and career pathways encouraging students to actively pursue careers in space science and technology.
The lecture was highly informative and inspiring providing participants with both technical knowledge and motivation to explore opportunities in the field of space science.
