India is gearing up for a major achievement in its space program as the Indian Space Research Organization (ISRO) prepares for its 100th rocket launch on January 29, 2025. This landmark event will take place from the Sriharikota spaceport in Andhra Pradesh, where ISRO has conducted all of its major launches since 1979. The rocket making this historic flight is the Geosynchronous Satellite Launch Vehicle F-15 (GSLV F-15), which will carry the NVS-02 satellite into space. This launch marks a century of rocket launches for India, showcasing ISRO’s growth and technological advances over nearly five decades.
A Troubled History Turned Triumph
The GSLV F-15 rocket, part of ISRO’s Geosynchronous Satellite Launch Vehicle family, has had its share of challenges. Previously referred to as the ‘naughty boy’ of ISRO, it has experienced six failures in 16 launches, resulting in a failure rate of 37%. However, despite these setbacks, it has played a key role in ISRO’s achievements, particularly in the development of cryogenic engines—a technology India had to develop independently after facing obstacles in acquiring it from Russia due to external political pressures.
From SLV to GSLV: ISRO’s Rocket Legacy at Sriharikota
ISRO’s 100th rocket launch will be a testament to India’s space journey, which began on August 10, 1979, with the launch of the Satellite Launch Vehicle (SLV). Almost 46 years later, the GSLV F-15 will be the 100th rocket to lift off from Sriharikota, marking a significant achievement for India’s space exploration and technological advancements.
This launch will also see the placement of the NVS-02 satellite into a Geosynchronous Transfer Orbit. This satellite is a key part of India’s NavIC (Navigation with Indian Constellation) system, which provides precise positioning and timing services for users in India and nearby regions. The development of NavIC was a response to India’s inability to access GPS data during the 1999 Kargil conflict with Pakistan, leading Prime Minister Atal Bihari Vajpayee to vow the creation of a homegrown navigation system.
A Bright Future for ISRO’s Space Mission
With the 100th rocket launch, ISRO is not only celebrating its past achievements but also looking toward an exciting future. The space agency has overcome numerous challenges in the development of its space technology, and the GSLV F-15 launch represents another important step forward. If all goes well, this milestone will be a proud moment for ISRO and the nation as a whole.
