The Indian Department of Space has tightened resignation and voluntary-retirement rules after more than 100 scientists left the Indian Space Research Organisation (ISRO) [1].

This move comes as India attempts to protect its technical expertise during the execution of high-profile space projects. The loss of specialized personnel threatens the continuity of complex engineering goals and the timeline for national space milestones.

The Department of Space issued a memorandum to stem the exodus of talent across ISRO centers throughout India [1], [2]. The new rules specifically target staff working on critical missions, such as the crewed Gaganyaan program, to ensure that essential knowledge remains within the agency [1], [3].

Reports on the scale of the departures vary slightly among sources. Some reports indicate that nearly 100 scientists have quit [2], while others state the number is over 100 [1], [3]. The government is acting to prevent further brain drain that could jeopardize the stability of ongoing operations.

The Gaganyaan mission is a central priority for the Indian government. By restricting the ease with which scientists can resign or take voluntary retirement, the Department of Space aims to maintain the human capital necessary to launch Indian astronauts into space.

Officials said the tightened rules are necessary to ensure the success of these critical missions. The agency is focusing on retaining the specific skill sets required for the complex phases of the Gaganyaan project and other strategic space endeavors [1], [2].

More than 100 ISRO scientists have resigned

The tightening of exit protocols suggests that ISRO is facing a significant talent retention crisis at a precarious moment in its operational history. By restricting the ability of scientists to leave, the Indian government is prioritizing mission success over labor flexibility, signaling that the Gaganyaan program is too critical to risk through personnel turnover.
