The memorandum addressed to Directors of ISRO Centers and Heads of Units has asked them to address this issue and not to accept any requests for voluntary retirement or resignation from scientific and technical personnel of Group ‘A’ associated with the Gaganyaan or other important missions or projects till their realization.

“It has been decided that voluntary retirement and resignation requests from scientific and technical personnel associated with Gaganyaan and other important mission/projects may not be accepted as a matter of routine,” the memorandum said.
