The launch of satellites from more than half a dozen Asian, Arab and European countries, as well as Canada and Brazil, which had been scheduled for 0607 GMT on Saturday, is now set for 0607 GMT on Sunday, Roscosmos added.
Space agency chief Dmitry Rogozin said the launch was postponed after a surge in voltage was detected.
"We decided not to take the risk," Rogozin told the RIA Novosti news agency.
Among them are the Challenge-1, the first satellite made completely in Tunisia, which was created by the Telnet telecommunications group.
