India, July 17 : India’s ambitious space programme has entered a crucial phase as the Indian Space Research Organisation (ISRO) responds to an increasing number of resignations from its scientific workforce. Concerned about the possible impact on strategic national missions, the Department of Space (DoS) has introduced stricter rules governing voluntary retirement and resignation requests from scientists and technical personnel working on key projects.
The move comes at a time when ISRO is simultaneously preparing for several high-profile missions, including the country’s first human spaceflight programme, Gaganyaan, advanced satellite launches, next-generation launch vehicle development, and future lunar exploration initiatives. Officials believe retaining experienced scientists is essential to maintaining mission schedules and ensuring the continuity of specialised research.
Department of Space Issues Fresh Directive
In a memorandum issued on July 14, the Department of Space instructed all major ISRO centres to exercise greater caution while processing resignation and voluntary retirement applications submitted by Group ‘A’ scientific and technical employees.
The directive specifically applies to personnel associated with Gaganyaan and other nationally significant projects. Rather than approving such requests at the institutional level, ISRO centres have now been instructed to forward them to the Department of Space for detailed examination before any final decision is taken.
Officials said the revised process aims to ensure that critical missions do not suffer because of the sudden departure of experienced professionals possessing highly specialised technical expertise.
Concerns Over Loss of Experienced Talent
The Department of Space acknowledged that an increasing number of scientists have sought voluntary retirement or resignation in recent months, creating concerns regarding project continuity.
According to the official memorandum, repeated exit requests from scientists engaged in prestigious national programmes have begun affecting the implementation of strategically important missions. Consequently, authorities have decided that resignations from personnel working on sensitive projects should no longer receive routine approval.
The government believes that experienced scientists play a vital role in maintaining continuity throughout long-duration space programmes, where knowledge transfer and technical expertise cannot easily be replaced.
Central Approval Made Mandatory
Under the revised policy, every resignation or voluntary retirement application submitted by scientific and technical personnel involved in important missions must now be reviewed by the Department of Space.
Centre directors have been instructed to send all pending and future applications along with detailed recommendations explaining the operational impact of each employee’s departure.
The final decision regarding acceptance of these requests will now rest with the Department of Space rather than individual ISRO centres.
Officials say the centralised review mechanism will allow the government to evaluate whether a scientist’s exit could adversely affect mission timelines or critical research activities.
Report Suggests Significant Number of Resignations
While the Department of Space has not officially disclosed the total number of resignations, reports indicate that the organisation has witnessed a noticeable increase in departures during the past year.
According to institutional sources cited by PTI, between 100 and 120 scientists and technical experts have reportedly resigned from ISRO over the previous twelve months.
Although these figures have not been formally confirmed by the government, they have drawn attention because they involve personnel working in advanced scientific and engineering disciplines.
The reported departures have raised questions about talent retention within India’s premier space agency during one of the busiest periods in its history.
Chairman Addresses Employee Turnover
ISRO Chairman V. Narayanan acknowledged that scientists have left the organisation but described employee movement as a normal occurrence in large institutions.
He explained that every major research organisation experiences some degree of workforce turnover as professionals pursue new career opportunities, academic research, or positions in emerging technology sectors.
At the same time, he emphasised that the latest government directive is intended to balance employee rights with the need to protect national projects that depend heavily on experienced scientific teams.
According to Narayanan, ensuring continuity in critical missions remains the organisation’s highest priority.
Shift From Earlier Policy
The latest directive represents a significant change from the policy introduced in November 2020.
Under the earlier framework, directors of ISRO centres and heads of various units had the authority to approve resignations and voluntary retirements for scientific personnel up to the rank of Scientist/Engineer-SG.
The revised guidelines remove that level of decentralisation for employees associated with strategically important missions.
Now, decisions involving such personnel will undergo additional scrutiny at the Department of Space before approval is granted.
Officials believe the revised system provides greater oversight in protecting projects of national importance.
UR Rao Satellite Centre Reports Highest Attrition
Among ISRO’s major facilities, Bengaluru’s UR Rao Satellite Centre (URSC) has reportedly experienced the largest number of resignations.
The centre plays a central role in designing, building, integrating and testing India’s communication, navigation, Earth observation and scientific satellites.
Institutional sources indicate that nearly 80 scientists and technical experts have left the facility over the past year.
Given URSC’s critical responsibilities in satellite manufacturing and mission support, retaining skilled personnel has become a major administrative priority.
Vikram Sarabhai Space Centre Also Affected
The Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram has also reportedly witnessed multiple resignations.
The centre serves as India’s primary establishment for launch vehicle research and development, contributing significantly to PSLV, GSLV and future rocket technologies.
Reports suggest that around 20 scientists have stepped down from the centre during the same period.
Although the number is smaller compared to URSC, experts believe even limited attrition in specialised divisions can affect ongoing research programmes.
Why Experienced Scientists Matter
Space missions involve years of planning, testing, simulation and engineering before launch.
Many scientists acquire expertise through decades of work on highly specialised technologies including propulsion systems, avionics, satellite integration, cryogenic engines, guidance software and human spaceflight systems.
Replacing such expertise is not always immediate because newly recruited scientists require extensive training before assuming leadership roles in complex projects.
Institutional knowledge accumulated over multiple missions often becomes one of an organisation’s greatest strengths.
For this reason, governments across the world adopt retention strategies for scientists involved in strategic programmes.
Gaganyaan Remains India’s Highest Priority
The government’s latest decision is closely linked to Gaganyaan, India’s first human spaceflight programme.
The mission represents one of ISRO’s most technologically demanding projects, involving crew safety systems, orbital operations, recovery mechanisms and human-rated launch vehicles.
The programme also serves as the foundation for India’s long-term ambitions in human space exploration, including future space stations and deep-space missions.
Officials believe maintaining experienced technical teams throughout the project lifecycle is essential to meeting safety standards and mission objectives.
Future Space Plans Require Stable Workforce
Beyond Gaganyaan, ISRO is working on several next-generation programmes expected to shape India’s future space capabilities.
These include advanced Earth observation satellites, communication systems, navigation technologies, reusable launch vehicle research, planetary exploration missions and future lunar initiatives.
Managing multiple complex programmes simultaneously requires a stable workforce with extensive technical expertise.
Government officials believe stronger oversight of resignation requests will help maintain continuity without preventing employees from exercising their legal rights.
Looking Ahead
The Department of Space’s latest directive highlights the growing importance of workforce management within India’s expanding space programme.
While employee movement remains a natural aspect of any large scientific organisation, retaining experienced professionals becomes increasingly important when multiple strategic missions are underway simultaneously.
The revised approval process reflects the government’s effort to protect national projects from unexpected disruptions while ensuring that India’s space ambitions continue to progress with the necessary technical expertise.
As ISRO advances toward major milestones in human spaceflight, satellite development and planetary exploration, maintaining a skilled and experienced scientific workforce is expected to remain one of its highest institutional priorities.
