Today, 23 August, India observes National Space Day — a day PM Narendra Modi declared in 2023 to mark the moment Vikram, the lander of Chandrayaan-3, made its historic soft landing on the south polar region of the Moon, a feat no other nation had achieved. That moment when Vikram made its tryst with its landing on the moon’s south pole surface is one which will continue to be etched in every Indian who witnessed this moment.
In the earlier attempt in 2019 the Chandrayaan 2 mission’s Vikram Landing was telecast live at the Nehru Science Centre, Mumbai and even at that late hour the auditorium was full — families, students, ordinary citizens who had come simply to watch, together, as the "15 minutes of terror" played out on the big screen. Unfortunately, Vikram lander came very close to soft landing but then did not achieve its goal. That night, when Chandrayaan-2's Vikram came so agonisingly close before its final-descent failure, our auditorium was packed with people who had come to witness history in the making. I had written then that cricket, cinema and chillies were long the common threads binding Indians across every divide — and that ISRO, in its quiet, unglamorous, relentless way, had earned itself a place alongside them as something every Indian, regardless of politics, could claim as their own.
After the failure of Vikram lander in 2019, the Chandrayaan 3 was a grand success when it made a soft landing on. 23 August 2023 and later enabling the Pragya rower to Rowe the moons surface creating history.
This year's National Space Day carries a more complicated set of emotions for me, and I suspect for many who have followed ISRO's journey closely.
Two Setbacks the Nation Needs to Understand
ISRO's Polar Satellite Launch Vehicle — the "workhorse" that has flown for over three decades and carried missions as consequential as Chandrayaan-1, the Mars Orbiter Mission and Aditya-L1 — has suffered two consecutive, and disturbingly similar, failures in less than a year. On 18 May 2025, PSLV-C61 lost the EOS-09 radar imaging satellite when an anomaly struck the rocket's third stage minutes after a flawless liftoff. ISRO set up a Failure Analysis Committee, adopted its recommendations, and returned to the launch pad on 12 January 2026 with PSLV-C62 — this time subjected to a record seven Mission Readiness Reviews. Yet the same third-stage anomaly recurred, and with it went the EOS-N1 earth observation satellite and fifteen co-passenger payloads, Indian and international.
What makes this particularly painful, beyond the loss of expensive hardware, is that both satellites, EOS-09 and EOS-N1, were meant to strengthen India's strategic surveillance capability at a time when our security establishment can least afford such gaps. For an organisation whose PSLV had, until recently, been a byword for dependability, two identical failures in the same critical stage is a rare and sobering occurrence that deserves honest scrutiny rather than either panic or denial.
The Quiet Exodus
Unfortunately, even as ISRO is making all our efforts in overcoming its setbacks, a development that has troubled many Indians and ardent ISRO fans, even more are the reports that over a hundred Group 'A' scientists and engineers — many of them experienced hands working on flagship programmes — have resigned or sought voluntary retirement from ISRO in recent months. Reports suggest that around eighty are said to have left the UR Rao Satellite Centre in Bengaluru alone, with more than twenty departing the Vikram Sarabhai Space Centre in Thiruvananthapuram. It appears that India's own burgeoning private space sector — now home to several hundred start-ups and drawing substantial fresh investment — is offering compensation and speed that a government salary structure struggles to match, which could be the reason for this unprecedented attrition. The Department of Space has taken cognisance of this and is reported to responded by centralising and tightening exit approvals, particularly for scientists attached to Gaganyaan and other critical missions, reversing an arrangement that had earlier let centre directors decide such matters locally. I hope that the famous ISRO culture which was painstakingly built by its founders - Vikram Sarabhai and Satish Dhawan - and those who followed them in leadership role, will help ISRO to bounce back to its successes.
The attrition has understandably created anxiety and that should not be dismissed as ordinary attrition. However, we must also look at this attrition with caution against reading it only as loss. If some of these scientists are moving into India's own private space industry rather than leaving the country altogether, they may still be building India's space capability — only outside ISRO's four walls rather than within them. What matters, as always, is whether the ecosystem as a whole keeps growing. Even so, the government would do well to ask why our most experienced hands are choosing to leave a mission-driven institution they once could not imagine leaving, and to address that honestly rather than simply making the door harder to walk through.
Holding On to the ISRO Culture
It is worth remembering what made ISRO different in the first place. Vikram Sarabhai did not build a bureaucracy; he built a culture — of scientific pursuits married to public purpose, of scientists who saw themselves as nation-builders in the mould of SITE, Aryabhata and the SLV programme, carried forward with equal conviction by Satish Dhawan. That culture is precisely what turned a modest, resource-starved space programme into one capable of soft-landing on the Moon's south pole on its very first attempt at that feat. Setbacks like PSLV-C61 and C62, and an exodus of experienced scientists, test that culture in ways that success never does. My hope, on this National Space Day, is that ISRO's leadership — and the political class that oversees it — recognises that retaining this culture requires more than tighter exit rules; it requires making ISRO a place scientists still choose, not merely one they are prevented from leaving.
What Lies Ahead
Even amid these challenges, ISRO's calendar for the months ahead is a reminder of why the country continues to invest its hopes in this institution. The first uncrewed Gaganyaan flight, G1, carrying the half-humanoid Vyommitra to validate life-support and re-entry systems, is targeted for the last quarter of this year, with India's first crewed spaceflight to follow in 2027. Beyond that lie Chandrayaan-4, a lunar sample-return mission, and the longer horizon of the Bharatiya Antariksh Station, envisaged to be operational by 2035. Each of these carries the same demand the Moon landing did: precision, patience, and scientists who are given the reason and the room to stay.
Revisiting ISRO's Story

In Closing
On this National Space Day, my greetings go out first and foremost to the scientists, engineers and technicians of ISRO — those who stay, and those who have moved on to build India's space capability elsewhere. May the Failure Analysis Committee's findings restore the PSLV to the reliability the nation has come to expect of it. May Vyommitra's flight this year go as smoothly as Vikram's did in 2023, and may our Gaganyatris follow safely in 2027. And above all, may ISRO — through setbacks as much as through triumphs — hold fast to the culture that Vikram Sarabhai and Satish Dhawan gave it: driven by purpose, undivided by politics, and belonging, always, to every Indian.
Jai Hind, Jai ISRO, Jai Vigyan.
