India celebrates every successful space mission with pride. The launch of Chandrayaan, the success of Mangalyaan, and the upcoming ambitions of Gaganyaan have made ISRO a symbol of national achievement. Every rocket that lifts off carries not just satellites, but the aspirations of 1.4 billion people.
Yet, behind the spectacular launches lies a quieter story that deserves equal attention.
Reports that around 100 scientists have left ISRO in recent years have sparked a debate. The official response has been reassuring: “Many have come, many have gone.”
That is true. Every organization experiences resignations, retirements, and new recruitment.
But perhaps we are asking the wrong question.
The issue is not how many scientists left.
The real question is why experienced scientists are choosing to leave one of India’s most prestigious scientific institutions.
Beyond the Headlines
ISRO has never been known for lavish salaries. Most scientists join because they want to solve difficult engineering problems, contribute to national missions, and be part of something larger than themselves.
So when experienced professionals decide to leave, the reasons are often more complex than money alone.
India’s rapidly growing private space sector now offers:
Better compensation packages.
Employee stock ownership (ESOPs).
Faster decision-making.
Greater flexibility for innovation.
Opportunities to build commercial technologies.
Many former ISRO scientists are now helping companies such as Skyroot Aerospace, Agnikul Cosmos, Pixxel, and Bellatrix Aerospace compete globally.
This is not necessarily a loss for India.
It is, however, a signal that the country’s scientific ecosystem is changing.
Is This a Failure of Government?
Some critics have blamed the government.
Others dismiss the issue entirely.
The truth probably lies somewhere in between.
There is no credible evidence that scientists are leaving because of political pressure or any deliberate attempt by the government to weaken ISRO.
At the same time, governments cannot completely distance themselves from the issue.
Policies determine salaries.
Policies shape promotions.
Policies influence research funding.
Policies decide how much bureaucracy scientists must navigate before they can innovate.
When talented people consistently find better opportunities elsewhere, policymakers have a responsibility to ask whether public institutions are keeping pace with changing expectations.
The Cost of Losing Experience
Replacing a scientist on paper is easy.
Replacing twenty years of experience is not.
Senior scientists mentor younger engineers, troubleshoot complex missions, preserve institutional knowledge, and make decisions that cannot be learned from textbooks alone.
Every resignation represents not just one employee leaving, but years of accumulated expertise walking out the door.
That is why talent retention matters.
What Should Be Done?
India does not need to stop scientists from joining private companies.
Healthy competition often drives innovation.
Instead, the government should focus on making ISRO an institution where talented people want to build long-term careers.
Some reforms worth considering include:
Modernizing compensation where feasible.
Creating faster and more transparent promotion systems.
Reducing administrative hurdles.
Expanding research funding.
Encouraging collaboration between ISRO and private startups.
Allowing greater movement between the public and private sectors without penalizing career progression.
The objective should be to make staying at ISRO as attractive as leaving it.
A Space Race Needs More Than Rockets
India rightly dreams of becoming a global space power.
But rockets alone do not build that future.
Scientists do.
Laboratories do.
Research culture does.
Every successful mission begins years before launch, inside offices and laboratories where engineers solve problems that the public never sees.
If those workplaces become less attractive than private alternatives, India must pay attention.
Social Media Had Its Say
As always, the internet found humour in the debate.
“Scientists calculate escape velocity. Some are now calculating career velocity.”
“Rocket science wasn’t the hardest challenge. Paperwork was.”
“ISRO launches satellites into orbit. Private companies launch salaries into another orbit.”
"Mission Moon was successful. Mission Retain Talent is still under development.”
“Gravity couldn’t stop the rocket. Bureaucracy couldn’t stop the resignation.”
Humour aside, the underlying concern is real.
The Real Countdown
Every government proudly celebrates a successful rocket launch.
Perhaps it should celebrate something else too:
Creating an environment where India’s brightest scientists never feel that their biggest career opportunity lies outside the institution they once dreamed of joining.
ISRO has survived setbacks before, and it will continue to produce remarkable achievements.
But the strength of any scientific institution is measured not only by the rockets it launches—it is measured by its ability to inspire, retain, and empower the people who build them.
Because in the end, nations do not win the space race with machines.
They win it with minds.
