Sept. 11, 2012 - South Korea announces the third launch of its
KSLV-1 will be held on Oct. 26-31 with Oct. 26 designated as the primary candidate date.
Oct. 24, 2012 - The KSLV-1 is moved to the launch pad from the rocket assembly building and erected on the launch pad. The KSLV-1 is to scheduled to lift off from Naro Space Center on Oct. 26.
Oct. 26, 2012 - The scheduled launch of the KSLV-1 is delayed indefinitely due to a damaged rubber seal in the connector between the rocket and its launch pad.
Oct. 29, 2012 - South Korea's Launch Preparation Committee designates Nov. 9-24 as new candidate dates for the third launch of the KSLV-1.
Nov. 14, 2012 - The Launch Preparation Committee announces the third launch will be further delayed after Russian engineers confirmed the damages to the rubber seal in the connector had been caused by a defective part in the connector, forcing them to replace the defective part.
