Naro-1 ((朝鮮語:나로호)), previously designated the Korea Space Launch Vehicle or KSLV, is South Korea's first carrier rocket. and the first South Korean launch vehicle to achieve Earth orbit. On 30 January 2013 the third Naro-1 vehicle built successfully placed STSAT-2C into low Earth orbit. The solid-fuel rocket second stage was built by KARI, the national space agency of South Korea, and Korean Air. The first stage was purchased by KARI after manufacture by NPO Energomash, the maker of the Russian Angara rocket. Neither the maiden flight on 25 August 2009 nor the second flight on 10 June 2010 reached orbit. The third flight on 30 January 2013 successfully reached orbit. The launches took place from the Naro Space Center. The official name of the first KSLV rocket, KSLV-I, is Naro, which is the name of the region in which Naro Space Center is located. == History == In 1992, Republic of Korea developed and launched several satellite systems and rockets overseas, such as the solid-fueled KSR-1 and KSR-2 sounding rockets. In 2000, Republic of Korea began construction of the Naro Space Center, located on Naro Island in Goheung, south of Seoul, with Russian assistance. The work was completed by the launch of the KSR-3 liquid-propellant sounding rocket on 28 November 2002. South Korea announced in 2002 that it intended to develop a small satellite launch vehicle by 2005 that would be based on technology flown on the KSR-3 test vehicle. The launcher would be entirely indigenous, based on the thrust LOX/kerosene motor used for the KSR-3 rocket stage.〔(KSR-3 on astronautix.com )〕 In 2005 a change was announced, indicating that they would use the Russian RD-191 as the vehicle's first stage. The program, like that of the Angara, was subject to continuous funding shortages and schedule delays. On 26 October 2004, during the visit of a GKNPTs Khrunichev delegation headed by A. A. Medvedev, Director General to Republic of Korea, a contract was signed to design and build a Space Rocket Complex for the small-lift launch vehicle KSLV-1. The design represented a joint effort between GKNPTs Khrunichev partner NPO Energomash "V. P. Glushko", who would build the first stage of KSLV-1, and Republic of Korea KARI, who would design and produce the second stage. As the prerequisite to signing the contract South Korea joined the Missile Technology Control Regime (MTCR). All documentation was reviewed by the Russian Space Agency (RSA), and the joint project to build the Korean rocket complex was approved. The vehicle was unveiled at the Naro Space Center in Goheung, South Jeolla Province in October 2008. South Korea has spent some KR₩500 billion (US$490 million) since 2002 on the project. The total cost of the first three launches was over 500 billion won (US$450 million), raising concerns among the Korean populace about the value of the Naro space program. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Naro-1」の詳細全文を読む スポンサード リンク
