A new attempt to launch the third Russian-South Korean space rocket KSLV-1 may be made on November 29, a source in the Russian aerospace industry told Interfax-AVN on Monday.

"After a rubber sealer for an installation connecting the filling main of the launcher with the first stage of the carrier rocket was delivered to Korea last Saturday considering the time to prepare a new launch it may take place around November 29," the source said.

"The final decision on the launch date will be made by the Russian-South Korean launch commission on Thursday," he said.

Initially the takeoff was scheduled for October 26 but in the process of preparing the launch a defect was discovered in the filling system which resulted in the postponement of the flight.

The KSLV-1 should take off from the Naro Space Center in South Korea. Its first stage was designed and produced by the Khrunichev Space Center.

Its first stage is derived from a multipurpose rocket module that will be used for making the first stage of the future Angara launch vehicle.

The previous launches of KSLV-1 were made in 2009 and 2010 and both failed. Investigators looking into the cause of both said that the first stage was not to blame in either case.
