MOSCOW (AFP) - They may be working to reach the final frontier, but employees of Russian space agency Roscosmos face going no further than Russia for their holidays. Roscosmos new chief Vladimir Popovkin has imposed a formal ban on managers and staff employed by its rocket-making subsidiaries taking holidays abroad, the Izvestia daily said, quoting an internal directive. The Soviet-style edict applies to workers who are judged to have knowledge of particularly important or secret information connected to Russias rocket industry. It applies not only to subsidiaries of Roscosmos but also companies with which it has concluded contracts for work deemed to be of a sensitive nature, Izvestia said.
