Introduction

India’s premier space agency, the Indian Space Research Organisation (ISRO), is facing an unprecedented wave of resignations from its scientific workforce. In response, the Department of Space (DoS) has issued a fresh directive instructing officials not to accept resignation or voluntary retirement requests from key scientific and technical staff as a routine matter. This move comes at a critical time, as the country pushes forward with its ambitious Gaganyaan human spaceflight mission and other high-priority space projects.

In this post, we break down what happened, why it matters, and what it could mean for the future of India’s space ambitions.

What Exactly Happened?

On July 14, 2026, the Department of Space issued an internal memorandum addressing a growing trend within the organization. The memo noted that there had been a noticeable spike in requests for voluntary retirement and resignation from Group ‘A’ scientific and technical personnel including those directly involved in the Gaganyaan mission and other nationally significant space projects.

According to reports, more than 100 to 120 ISRO scientists and technical staff have resigned in recent months. Breaking this down further:

• Nearly 80 resignations reportedly came from the U.R. Rao Satellite Centre (URSC) in Bengaluru.
• Around 20 resignations were recorded at the Vikram Sarabhai Space Centre (VSSC) in Thiruvananthapuram.

Some of the departures involved highly experienced personnel, raising concerns across the space community.

Who Are Some of the Scientists Who Resigned?

Among the notable exits:

• Victor Joseph T, who served as Project Director of the LVM3 (GSLV Mk III) project at VSSC, resigned earlier this year.
• Aditya Rallapalli, a key scientist associated with the Chandrayaan 3 mission, also quit.
• The SpaDeX Project Director at URSC was reportedly among those who left as well.

These are not junior-level exits many of the resigning scientists held senior, mission-critical roles, which explains why the government has taken this unusual step of intervening in the exit process.

What Do the New Rules Say?

Under the revised procedure introduced by the Department of Space:

1. ISRO Centre Directors and Heads of Units have been instructed not to accept resignation or voluntary retirement requests from Group ‘A’ personnel working on Gaganyaan or other important missions as a routine matter — at least until these projects are completed.
2. Any such request, including from scientists up to the Scientist/Engineer-SG level, must now be formally referred to the Department of Space along with a recommendation, for a final decision to be taken at a higher administrative level.

In simple terms: individual centres can no longer approve these exits on their own. Every case will now be reviewed centrally before being accepted or rejected.

Why Is This Important?

ISRO’s Gaganyaan mission — India’s first attempt at human spaceflight — is one of the most technically complex and nationally prestigious projects in the country’s space history. Losing experienced scientists mid-project can lead to:

• Loss of institutional knowledge and technical expertise
• Delays in mission timelines
• Increased pressure on remaining staff
• Difficulty in recruiting and training replacements quickly enough

Earlier this year, the DoS informed Parliament that the science and technology category alone had a vacancy of 1,636 personnel, with recruitment underway for 1,261 positions. This existing staffing gap makes the recent wave of resignations even more concerning for project continuity.

The Government’s Response

Union Minister Jitendra Singh downplayed concerns about a manpower crisis at ISRO, pointing out that personnel turnover is a normal part of any large organization. He noted that even former ISRO Chairman S. Somanath, who was closely involved with Gaganyaan, has since moved on yet the mission continues to progress. According to the minister, the new memo is intended to ensure that resignation decisions are made at a more mature, considered level within the organization, rather than being processed automatically.

What This Means Going Forward

While the government maintains that ISRO’s projects will not suffer, the sheer scale of recent resignations especially among senior mission leads suggests underlying issues that may need to be addressed beyond just tightening exit paperwork. Retention strategies, career growth opportunities, and competitive compensation compared to the private space sector could all play a role in whether this trend continues or reverses.

For now, all eyes will be on how the Department of Space handles pending and future resignation requests, and whether these administrative changes are enough to stabilize the workforce driving India’s space missions forward.

Frequently Asked Questions (FAQ)

Q1: Why did ISRO scientists resign in large numbers? While the exact reasons vary by individual, reports suggest around 100-120 scientists and technical staff have left in recent months, including several senior personnel from major missions.

Q2: Can ISRO scientists still resign under the new rules? Yes, but resignation and voluntary retirement requests from Group ‘A’ personnel on key missions like Gaganyaan will no longer be approved automatically at the centre level. They must be reviewed and decided upon by the Department of Space.

Q3: When was the new memo issued? The internal memorandum was issued on July 14, 2026.

Q4: Will this affect the Gaganyaan mission timeline? The government has stated that ongoing projects will not be impacted, though the loss of experienced personnel remains a point of concern for many observers.
