TEDx Talks - India's Space Journey: Bridging the Gap Between Innovation and Society | Aditya Bhardwaj | TEDxMAIT
India's space journey began in a small fishing village, Tumba, with launches initially managed from a church and transported by bicycles. The program was initiated by Dr. Vikram Sarabhai in 1962, leading to the formation of ISRO in 1969. Early launches used foreign rockets, but by 1980, India developed its own satellite launch vehicle, SLV-3. Over the years, India advanced its launch capabilities with PSLV and GSLV, enabling missions like Chandrayaan and Mangalyaan. The development of satellites has been crucial, with indigenous satellites like Aryabhata and Rohini marking significant milestones. India has developed various satellite types for communication, remote sensing, and navigation, supporting applications in agriculture, disaster management, and more. Future plans include the Gaganyaan mission, a space station by 2035, and a lunar mission by 2040. ISRO is also focusing on advanced technologies like humanoids and quantum communications, aiming to secure satellite communications and develop vertical takeoff and landing vehicles. Students are encouraged to participate in ISRO's programs to contribute to India's space journey.

1. 🚀 Launching India's Dreams: The Rocket's Journey
- The onboard computer conducts comprehensive pre-flight checks ensuring systems function correctly, which is critical for successful liftoff.
- Automatic launch sequences, once initiated, produce millions of Newtons of thrust, emphasizing the power and complexity of the launch.
- The first stage of the launch vehicle completes its burn at an altitude between 60 and 70 km, a crucial phase for gaining initial momentum.
- At approximately 100 km altitude, the payload fairing separates, signifying the vehicle's transition into space environment.
- Control transitions to the upper stage after the second stage crosses 100 km, highlighting a shift in propulsion strategy to achieve orbit.
- The upper stage's role is pivotal in delivering the satellite into its precise orbit, ensuring successful deployment.
- Consistent telemetry tracking during the launch ensures adherence to the planned trajectory, providing critical data for real-time adjustments.

- The Indian Space Research Organisation (ISRO) was established in 1969, initiating India's space exploration journey with the use of the US-made Nike Apache rocket, launched from Tumba at the Earth's magnetic equator, which provided an initial advantage due to Earth's rotation.
- 1967 marked the launch of the first indigenous vehicle, Rohini 75, from Indian soil, representing a crucial step in developing domestic capability.
- In 1980, the Satellite Launch Vehicle 3 (SLV-3), led by Dr. A.P.J. Abdul Kalam, was developed as a four-stage rocket with all solid motors, marking a pivotal progression in India’s space technology.
- The Augmented Satellite Launch Vehicle (ASLV) was developed to increase payload capacity beyond SLV-3, utilizing advanced technologies such as the ston booster, enhancing stability and control.
- The Polar Satellite Launch Vehicle (PSLV), introduced in 1994, drastically increased payload capacity from 30 kg in SLV-3 to 1.7 tons in Low Earth Orbit (LEO), revolutionizing India's satellite launch capabilities.
- To further enhance payload capacity, the Geosynchronous Satellite Launch Vehicle (GSLV) was developed, increasing capacity from 1.7 tons to 2.2 tons, and was notably utilized for high-profile missions like Chandrayaan-3 and Mangalyaan, showcasing India's growing prowess in space exploration.
