The Indian government has tightened approval rules for voluntary retirement and resignations after more than 100 ISRO scientists left the agency [1].

This exodus of high-level technical personnel threatens the timeline of critical space projects, most notably the Gaganyaan mission. The loss of experienced Group 'A' staff during a final countdown phase could create significant knowledge gaps in mission-critical systems.

On July 14, 2026, the Department of Space issued a memorandum to restrict how technical personnel exit the organization [2]. The move follows a surge of departures from key facilities, including the Vikram Sarabhai Space Centre (VSSC) and the U.R. Rao Satellite Centre (URSC) [3]. These centers are central to India's current orbital and crewed flight ambitions.

"There has been a spate of requests for voluntary retirement and resignation from Group 'A' scientific/technical personnel of ISRO," a Department of Space official said [4].

While some reports state exactly 100 scientists quit, other sources indicate the number is over 100 [1], [4]. The government is now requiring stricter oversight for these requests to ensure that the departure of a specialist does not jeopardize an active project. This policy shift specifically targets Group 'A' scientific and technical personnel, the highest tier of the agency's technical workforce [1].

The timing of these resignations is particularly sensitive as India prepares for the Gaganyaan mission. The agency must maintain a stable workforce of engineers and scientists to ensure the safety and success of the crewed flight. By tightening exit rules, the government aims to prevent a sudden drain of institutional memory and technical expertise during the mission's most critical phase [2].

“More than 100 ISRO scientists have resigned or taken early retirement.”

The mass departure of senior scientists suggests a potential tension between ISRO's rigorous mission demands and the professional satisfaction or retention strategies for its top tier of talent. By implementing restrictive exit policies, the Indian government is prioritizing national strategic goals—specifically the success of the Gaganyaan mission—over the individual employment flexibility of its scientists, highlighting the high stakes of India's current space race ambitions.
