NARO SPACE CENTER, South Korea, Jan. 30 (Yonhap) -- The following are quick facts about South Korea's Korea Space Launch Vehicle-1 (KSLV-1) that is scheduled to be launched Wednesday.
-- The KSLV-1, also known as Naro, is a two-stage space launch vehicle that stands 33.5 meters tall. It has a maximum diameter of 2.9 meters and weighs 140 tons when fully loaded. Without fuel, the rocket weighs 10 tons, with the outer walls being 2 millimeters thick.
-- The Russian-built first stage rocket uses kerosene as its fuel and liquefied oxygen as its oxidizer. It stands 25.8 meters tall and has one engine operated by a turbo pump system that is capable of generating 170 tons of thrust.
-- The second stage rocket is manufactured in South Korea and uses a solid fuel propulsion system. It has a length of 7.7 meters and has a 7-ton thrust single kick motor engine.
-- The fairing assembly is part of the second stage rocket. The two fairings that cover the scientific satellite during the ascent stage weigh around 300 kilograms and stand 5.3 meters tall. The two fairings are designed to be jettisoned 216 seconds after blastoff.
-- Naro's payload, the Science and Technology Satellite-2C (STSAT-2C), roughly weighs 100 kilograms and is powered by solar panels that can generate 160 watts of power. It has an operational lifespan of about one year and is equipped with various antennas, sensors, and a femtosecond laser oscillator, which are all designed to test their own functions and capabilities in space. The satellite can orbit the Earth about every 100 minutes, or 14 times a day.
