SEOUL - South Korea was preparing Tuesday to launch its homegrown space rocket Nuri in the second attempt to put satellites into orbit, a critical mission for the country's space program, according to Yonhap news agency.
The 200-ton Nuri is set to blast off from the Naro Space Center in the country's southern coastal village of Goheung at around 4pm, the Korea Aerospace Research Institute (KARI) said.
The state-run institute plans to announce the exact time of the liftoff at 2.30pm, it reported.
South Korea had planned to launch the three-stage rocket last Thursday, but a technical glitch in the oxidiser tank sensor forced the country to postpone the liftoff.
In a meeting of Nuri's launch management committee Monday, the science ministry and KARI concluded Nuri's final technical inspection proceeded without any problems.
The weather forecast also satisfied launch conditions.
A successful launch would make South Korea the seventh country in the world to have developed a space launch vehicle that can carry a more than 1-tonne satellite, after Russia, the United States, France, China, Japan and India.
Tuesday's launch would be Nuri's second liftoff after its first attempt ended in failure, Yonhap reported.
In October, Nuri successfully flew to its target altitude of 700 kilometres but failed to put a dummy satellite into orbit, as its third-stage engine burned out earlier than expected.
KARI engineers reinforced an anchoring device of the helium tank inside Nuri's third-stage oxidiser tank.
This time, Nuri will be loaded with a 162.5-kilogramme performance verification satellite to test the rocket's capabilities and four cube satellites, developed by four South Korean universities for academic research purposes, along with a 1.3-tonne dummy satellite.
South Korea, a relative latecomer to the global space development race, has invested nearly 2 trillion won (US$1.8 billion) in building Nuri since 2010.
South Korea's rocket launches ended in failures in 2009 and 2010.
In 2013, South Korea successfully launched its first-ever Naro space rocket, though its first stage was built in Russia.
The country aims to conduct four additional Nuri rocket launches by 2027. South Korea has also launched a preliminary feasibility study for the successor to the Nuri with the goal of sending a lunar landing module to the moon in 2031. - Bernama
