In 2005 it was announced that the KSLV-I would not fly until 2007. It was now a completely different vehicle, consisting of a first stage derived from the Russian Angara launch vehicle, and a solid propellant second stage of South Korean manufacture. First launch 2009.08.25.

AKA: Korea Space Launch Vehicle-I;KSLV-I. Status: Active. First Launch: 2009-08-25. Last Launch: 2013-01-30. Number: 3 . Payload: 100 kg (220 lb). Thrust: 1,910.00 kN (429,380 lbf). Gross mass: 140,000 kg (300,000 lb). Height: 30.00 m (98.00 ft). Diameter: 3.90 m (12.70 ft). Apogee: 300 km (180 mi).

It had been decided to develop a first stage in collaboration with Russia, based on the still-in-development Angara launcher. This would be an order-of-magnitude larger than the original KSLV-I design. The first test of this vehicle, still designated KSLV-I, was moved to 2007 and would consist of a launch of the first stage with a South Korean solid rocket motor kick stage to place the small 100-kg satellite into orbit.

KARI oversaw basic system design, system management of the launch vehicle, and basic design of the ground equipment. International cooperation plans called for joint development of the launch vehicle and interface design for the 100 kg Science Satellite 2.

LEO Payload: 100 kg (220 lb) to a 300 km orbit at 38.00 degrees.

2009 August 25 - . 08:00 GMT - . Launch Site: Goheung. LV Family: Angara. Launch Vehicle: Naro-1. FAILURE: First and second stages operated correctly, but half of payload fairing failed to separate. Extra mass prevented the second stage and payload from reaching orbital velocity, and the satellite reentered over New Guinea..
