Brain Drain in India’s Space Program

The recent spate of resignations from key Indian Space Research Organisation (Isro) missions has prompted the department of space to tighten rules on voluntary retirement and resignation requests. The move is aimed at stemming the exodus of scientists working on critical projects such as Gaganyaan.

At least 100 scientists have quit in recent months, with around 80 leaving from the URSC alone, and at least 20 from VSSC. Key personnel like Victor Joseph, project director for LVM-3, and a young scientist who was part of the Chandrayaan-3 team, are among those who have left.

Isro officials downplay the significance of this exodus, citing it as a normal part of any organization’s life cycle. However, the scale of departures suggests otherwise. The memorandum issued by the department of space reverses an administrative change made in 2020 that gave centre directors the authority to accept voluntary retirement and resignation requests from Group A scientific and technical personnel up to scientist/engineer-SG level.

This reversal highlights the concern about losing experienced scientists working on national missions. Isro’s struggles with attrition are not new, with nearly half of its new recruits quitting between 2004 and 2007, as reported earlier by The Times of India. Official figures also show that around 700 employees resigned between 2012 and 2024.

However, replacing experienced scientists working on national missions is proving to be a challenge. The Chandrayaan-3 scientist who quit was Aditya Rallapalli, the mission’s project manager (simulations), who led a team that generated nearly 25 terabytes of data from over 1-lakh tests, an effort critical to validating Moon landing sequence.

A Brain Drain with Long-Term Consequences

The recent departures are a symptom of a larger issue – Isro’s struggle to retain its best talent. While the organization is working to fill vacancies and create new positions, replacing experienced scientists working on national missions is proving to be a challenge. This brain drain has long-term consequences for India’s space program.

Isro’s reliance on its personnel is evident in the memorandum, which notes that resignation and voluntary retirement requests from scientists associated with Gaganyaan and other important missions “may not be accepted as a matter of routine.” Centre directors have been advised not to accept such requests until those projects are completed. This reversal highlights the concern about losing experienced scientists working on national missions.

A Changing Landscape for Indian Space Research

The departures from Isro’s key missions come at a time when the organization is expanding its capabilities and partnerships. In 2025-26, Isro plans to recruit around 1,050 scientific, technical, and administrative posts. The cadre review approved last year has regularised 466 project posts and created about 460 higher-grade positions.

However, these efforts may not be enough to stem the tide of attrition. Experienced scientists are leaving for better opportunities in the private sector, which Isro’s success in the recent Chandrayaan-3 mission has inadvertently fueled.

Implications for India’s Space Program

The brain drain in India’s space program has significant implications for the country’s long-term goals in space exploration and development. Losing experienced scientists working on national missions will not only slow down current projects but also compromise future endeavors. The government needs to address this issue urgently, providing Isro with the resources and incentives it needs to retain its best talent.

The department of space’s memorandum is a step in the right direction, but more needs to be done to stem the tide of attrition. Isro must revamp its recruitment strategy, creating a more attractive work environment for scientists and engineers. The government should also provide additional funding for research and development, ensuring that India’s space program remains competitive.

The future of India’s space program hangs in the balance. Will the country be able to retain its best talent and achieve its ambitious goals in space exploration? Only time will tell.
