2013年1月30日,韩国成功发射了韩国航天运载器-1(KSLV-1),又名罗老号运载火箭。继前两次发射失败后,此次发射对韩国尤为重要。发射成功,标志着韩国成为全球第11个具备航天发射能力的国家。罗老号运载火箭因在罗老航天发射中心发射而得名。该型火箭为两级轻型运载火箭,于2002年开始研制,研发成本约4.71亿美元。火箭总重约140t,总长约33mm,箭体直径2.9m。火箭第一级为液体火箭发动机,采用单台RD151发动机,推力为1 670kN,比冲338s。第二级为固体火箭发动机,采用KSR-1发
On January 30, 2013, South Korea successfully launched the Korean Aerospace Carrier-1 (KSLV-1), also known as the Lo Laoting Launch Vehicle. Following the failure of the previous two launches, the launch is particularly important to South Korea. The successful launch marked the ROK becoming the 11th country in the world with space launch capability. Lo Lao Launch Vehicle named for launch at Lao Space Launch Center. The rocket is a two-stage light launch vehicle that began development in 2002 with a research and development cost of about 471 million U.S. dollars. The total weight of the rocket is about 140t, with a total length of about 33mm and an arrow body diameter of 2.9m. The rocket’s first stage is a liquid rocket engine, with a single RD151 engine, with a thrust of 1,670kN and a specific impact of 338s. The second stage is a solid rocket engine, using KSR-1 hair
