The failed PSLV attempt to launch a navigation satellite is unlikely to affect future missions, as the Indian Space Research Organisation (ISRO) has developed a robust framework to analyse and rectify any issues that arise during launch operations.
Such failures, while unfortunate, provide valuable data that contribute to enhancing the reliability and performance of subsequent launches.
By meticulously analyzing the causes and effects of these setbacks, engineers and scientists gain critical insights that help identify vulnerabilities in the design, materials, or processes involved. This iterative learning process fosters innovation, allowing teams to implement improvements that not only rectify the issues encountered but also optimize future missions.
As a result, each challenge faced ultimately serves as a stepping stone toward greater achievements in aerospace exploration and technology advancement, underscoring the importance of resilience and adaptability in the face of adversity.
Furthermore, ISRO has a proven track record of overcoming challenges and learning from past experiences, ensuring that the agency remains committed to achieving its ambitious goals in satellite deployment and space exploration. As such, future missions are expected to proceed as planned, bolstered by the lessons learned from this incident.

After 39 consecutive successful launches, the Indian Space Research Organisation had almost made it appear that launching satellites was indeed child’s play when it used its workhorse rocket, the Polar Satellite Launch Vehicle. But the PSLV, which has been placing satellites in their respective orbits for the past 24 years, faced a setback on August 31.
The PSLV-C39 rocket, which carried the eighth satellite of the Indian Regional Navigation Satellite System (IRNSS), experienced a normal lift-off and flight events. This showcases the reliability of the PSLV. Although the mission faced a challenge with the heat shield not separating as intended, this valuable experience will contribute to future improvements and successes.
This event marks only the second instance of a setback in PSLV’s remarkable 41 launches, with the first occurring back in 1993. The determination and resilience of the team continue to pave the way for future endeavors in space exploration.

Over the years, the PSLV has been crucial for ISRO, and this February it set a world record by launching 104 satellites at once. Given its strong track record, the recent mission failure is surprising.
The lift-off and separation of the first and second stages were smooth, while the heat-shield separation, which occurs at about 100-110 km altitude, is a less critical operation, as the temperature won’t harm the satellite once it passes this height.
The failed mission serves as a reminder that utmost care and scrutiny are required before every single launch. While scientists are working to identify the cause of the anomaly in the heat-shield separation event, the failed mission should have no impact on future launches involving the vehicle.
The mission’s failure is disappointing, especially since the IRNSS-1H satellite was put together by ISRO and a private company from Bengaluru. This marks the first time a single private firm took part in satellite construction. The satellite itself did not cause the mission’s failure. Starting in mid or late 2018, the space organisation will allow private companies to build up to 18 spacecraft each year.
The IRNSS-1H satellite was launched to replace the inoperational IRNSS-1A satellite due to the failure of its atomic clocks. Currently, only six of the seven satellites are working, creating gaps in the navigation data. With this mission’s failure, India will need to wait longer for a new replacement for IRNSS-1A.

The IRNSS was created so that the country would not need to rely on American-based GPS data; this strategic initiative aims to enhance national security and foster technological independence.
With a constellation of satellites positioned to provide extensive coverage over the Indian subcontinent and surrounding regions, the encrypted, accurate positioning and navigation information provided by the system will make Indian military operations self-reliant.
Furthermore, the ability to access reliable geolocation data will not only bolster defense capabilities but also support various civil applications. It is contributing significantly to the economic growth of the nation by enabling advancements in transportation, agriculture, and disaster management.
This pioneering step underscores India’s commitment to developing indigenous technologies that further strengthen its sovereignty and resilience in a rapidly evolving geopolitical landscape.
