Resignations from critical missions have triggered tighter exit rules and a deeper debate over talent retention
NEW DELHI (India CSR): India’s space programme is confronting an unexpected human-resource challenge at a time when the country is preparing for some of its most ambitious missions.
More than 100 scientists and technical personnel have reportedly resigned or sought voluntary retirement from the Indian Space Research Organisation (ISRO) in recent months. Some reports place the number as high as 120. Several departing professionals are believed to have worked on strategically important programmes, including Gaganyaan, SpaDeX, Chandrayaan-3 and the LVM3 launch vehicle.
Although the departures represent a relatively small share of ISRO’s overall workforce, their concentration in critical centres and technically demanding projects has raised concerns about institutional knowledge, leadership continuity and mission preparedness.
The Department of Space responded by issuing an internal memorandum on July 14, 2026, tightening the process for accepting resignations and voluntary retirement requests from scientific and technical personnel associated with nationally important projects.
The episode is more than a story about employees changing jobs. It points to a larger transition within India’s space economy: the organisation that created much of the country’s space talent must now compete with a private ecosystem that its own expertise and government reforms helped build.
How Large Is the Reported Exodus?
According to media reports, around 80 resignation or voluntary retirement cases emerged from the U R Rao Satellite Centre in Bengaluru, one of India’s most important spacecraft development facilities. At least 20 departures were reportedly associated with the Vikram Sarabhai Space Centre in Thiruvananthapuram, ISRO’s principal centre for launch-vehicle research and development.
The reported departures include professionals linked to some of India’s most visible space achievements. Among the names reported in the media are Victor Joseph, associated with the LVM3 programme, and Aditya Rallapalli, who played an important role in Chandrayaan-3 mission simulations. A senior professional associated with the SpaDeX mission has also reportedly left the organisation.
Rallapalli was credited with leading extensive simulations used to validate critical aspects of the Chandrayaan-3 landing sequence. The testing exercise reportedly involved more than one lakh simulations and generated approximately 25 terabytes of data.
The Department of Space has not publicly released a comprehensive, centre-wise list confirming every departure. The figure of 100–120 should, therefore, be understood as a number reported by media organisations citing official and institutional sources—not as a final number formally published by ISRO.
Why Are Scientists Leaving ISRO?
There is unlikely to be one explanation for every resignation. Career decisions are personal, and employees may leave for private-sector jobs, higher education, family considerations, entrepreneurship or retirement. However, the present pattern appears to reflect a combination of private-sector opportunities and longstanding institutional pressures.
Private Space Companies Offer More Competitive Packages
India’s commercial space industry has expanded rapidly following the opening of the sector to private participation. IN-SPACe was established as an autonomous agency under the Department of Space to promote, authorise and supervise private space activities.
Private companies and space-technology startups can often offer experienced scientists substantially higher salaries, employee stock options, faster promotions and greater freedom to build specialised products.
For a mid-career scientist possessing rare expertise in propulsion, satellite systems, mission simulations, avionics or launch operations, the difference between government compensation and private-sector remuneration can be considerable.
The government’s own data demonstrates the scale of this emerging ecosystem. The number of registered Indian space startups rose from just one in 2014 to around 266 by late 2024. A subsequent government update said the figure had crossed 300 after the 2020 space-sector reforms. A ₹1,000-crore venture capital fund has also been approved to support the sector.

ISRO is consequently competing for talent with organisations that, in many cases, depend upon knowledge originally developed within the public space programme.
Research Aspirations and Institutional Constraints
Compensation is only part of the issue. Former employees and graduates of the Indian Institute of Space Science and Technology have previously raised concerns about limited research autonomy, slow decision-making and the assignment of young scientists to repetitive operational work.
Some employees enter ISRO expecting to undertake frontier research but find themselves working in what has been described as “production mode”—executing established processes under tight mission schedules. A lack of flexibility in choosing research problems, hierarchical approvals and limited opportunities for rapid experimentation can make universities, overseas institutions and private technology companies more attractive.
These concerns are not unique to ISRO. Public research institutions around the world struggle to balance administrative accountability with the intellectual freedom required for scientific innovation.
Career Growth and Workplace Pressures
Large government organisations generally operate through structured promotion and pay systems. These provide stability but may not sufficiently reward exceptional technical contributions or scarce expertise. Space missions also demand long working hours, particularly during integration, testing and launch campaigns. Scientists working at launch sites or on time-sensitive missions can face sustained pressure while receiving compensation governed by standard public-sector pay structures.
Private companies, by contrast, may provide faster career progression, leadership opportunities and direct financial rewards linked to technological or commercial performance.
Attrition at ISRO Is Not Entirely New
ISRO has experienced departures for decades. A 2007 report, for example, highlighted substantial attrition even as the agency accelerated recruitment. More recent accounts have also documented younger scientists leaving for higher education, research opportunities and private employment. The present situation is different because India now has a domestic private space industry capable of absorbing experienced ISRO professionals.
Earlier, the departure of a scientist often meant losing that expertise to another industry or country. Today, some former ISRO scientists remain within India’s space ecosystem by joining startups, established companies or new research ventures. That distinction matters. From ISRO’s institutional perspective, the departure is a loss. From the perspective of India’s broader space economy, it may represent a redistribution of knowledge.
What Did the Government’s July 14 Memorandum Change?
The Department of Space memorandum reportedly states that resignation and voluntary retirement requests from Group ‘A’ scientific and technical personnel associated with Gaganyaan and other important missions should not be accepted routinely. Such requests—including those from officers up to the Scientist/Engineer-SG level—must now be forwarded to the Department of Space with the recommendations of the concerned centre or unit head for a final decision.
The decision reverses, in part, the authority delegated to ISRO centre directors in 2020 to process certain resignation and voluntary retirement cases.
The memorandum reportedly observed that the recent volume of requests was adversely affecting projects of national importance. Centralising approvals gives the Department of Space greater oversight and may provide time to arrange replacements, complete knowledge transfers or reconsider the release of personnel performing indispensable roles.

However, stricter procedures do not necessarily resolve the conditions encouraging employees to leave. They may protect a project temporarily, but sustainable retention depends upon making scientists want to continue—not merely making departures administratively more difficult.
ISRO Chairman Says Missions Will Be Protected
ISRO Chairman V. Narayanan has acknowledged the departures but sought to reassure the public that the organisation has systems to maintain project continuity. He said employee movement occurs in every organisation and that responsibilities would be reassigned when someone left. He also explained that the memorandum was intended to ensure that strategically important projects did not suffer sudden disruption.
This confidence reflects ISRO’s institutional depth. The agency has traditionally relied on multidisciplinary teams rather than individual personalities, allowing responsibilities to be distributed when leadership changes. Nevertheless, replacing an experienced scientist on paper is not the same as immediately replacing years of tacit knowledge. Complex space systems depend on technical judgement developed through repeated tests, failures, reviews and mission experience.
Could Gaganyaan and Other Missions Be Affected?
There is no confirmed evidence that the reported resignations have caused a specific mission to be postponed. It would therefore be premature to suggest that Gaganyaan or another project is in immediate danger. The main short-term risks concern knowledge transfer, workload and continuity. When a highly experienced scientist leaves, remaining team members may have to absorb additional responsibilities while replacements learn specialised systems.
These concerns are particularly significant for Gaganyaan because human spaceflight demands exceptional standards of reliability, redundancy and safety. Decisions involving crew systems, launch vehicles, abort mechanisms, recovery operations and mission simulations require extensive coordination across multiple centres.
Similar concerns apply to satellite development, docking technology and launch-vehicle programmes. Even when formal documentation is complete, much of an organisation’s operational knowledge resides in the experience of its people.
Modi Government’s Space Reforms Created a New Talent Market
Under Prime Minister Narendra Modi, India’s space programme has gained greater political visibility and commercial orientation. The government established IN-SPACe, expanded opportunities for private companies, introduced the Indian Space Policy 2023 and encouraged technology transfers from ISRO. These reforms helped startups enter areas such as launch services, satellite manufacturing, geospatial intelligence, propulsion and space-based communications.
India has also achieved major scientific milestones during this period. Chandrayaan-3 made India the first country to achieve a soft landing near the Moon’s south polar region, while Aditya-L1 became the country’s first dedicated solar observatory mission.
The government’s reform agenda has therefore produced two simultaneous outcomes: it has expanded India’s space capabilities while creating a competitive market for ISRO-trained talent. That is not necessarily a policy failure. A successful national space economy cannot remain dependent on a single government organisation. The challenge is ensuring that the growth of private enterprise does not weaken the public institution responsible for strategic, scientific and high-risk missions.
Brain Drain or Space-Ecosystem Evolution?
The phrase “brain drain” captures only part of what is happening.
If experienced scientists leave ISRO for unrelated industries or opportunities overseas, the public space programme loses both talent and the benefits of years of taxpayer-funded training. If they join Indian space companies, however, their expertise may continue contributing to national capability.
The same departure can therefore be viewed in two ways:
- For ISRO, it represents the loss of institutional knowledge and experienced personnel.
- For private industry, it provides leadership and technical capacity that would take years to develop independently.
- For India, it may strengthen the overall space ecosystem—but only if ISRO remains sufficiently staffed to fulfil its strategic and scientific responsibilities.
The real concern is not mobility itself. It is whether the movement becomes so concentrated that key public missions lose critical capabilities faster than ISRO can rebuild them.
What ISRO and the Government Should Do
Administrative control may provide immediate stability, but a lasting solution requires a comprehensive talent strategy.
ISRO and the Department of Space could consider mission-based incentives for personnel possessing critical expertise, accelerated promotions for exceptional contributors and expanded opportunities for scientists to lead original research.
Flexible arrangements could allow experts to move temporarily between ISRO, universities and private companies without permanently severing institutional ties. Sabbaticals, joint laboratories, industry fellowships and fixed-term specialist positions could make scientific careers more adaptable.
The organisation may also need to examine workloads, workplace culture, research autonomy and leadership development. Exit interviews should be studied systematically to identify whether departures are primarily driven by compensation, management practices, research constraints or personal considerations.
Finally, succession planning must become integral to every strategic programme. No national mission should become excessively dependent on the knowledge of a small number of individuals.
A Wake-Up Call, Not Yet a Crisis
The reported departure of more than 100 scientists is significant, particularly because some of the professionals were associated with strategic programmes. But the available evidence does not establish that India’s space programme is facing institutional collapse.
ISRO remains a large, experienced and mission-driven organisation. Its 2025–26 annual report documents extensive activity across launch vehicles, satellites, space science, human spaceflight and technology development. (ISRO Annual Report 2025–26)
The resignations should nevertheless be treated as a warning. India cannot pursue human spaceflight, a national space station, advanced lunar exploration and a larger global commercial presence without retaining and continually developing high-quality scientific talent.
The Modi government’s decision to tighten exit procedures demonstrates concern about project continuity. Its longer-term test will be whether the administration moves beyond controlling departures and addresses the reasons experienced professionals may no longer see ISRO as their best place to innovate.
India needs both a strong ISRO and a vibrant private space industry. The country’s success will depend not on preventing scientists from moving, but on creating an ecosystem in which knowledge circulates without weakening the public institution at its centre.
Editorial note: The estimate of 100–120 departures and the identities of individual personnel are based on media reports. The Department of Space had not publicly released a complete, independently verifiable list of resignations at the time of publication.
