Naro failure attributed to fairing problems Korean Herald
An independent panel — tasked with finding the cause of the partial failure of Korea’s first rocket launch — confirmed yesterday that problems in the nose-fairing caused the satellite to veer off course.
NASASpaceflight.com say there are conflicting reports as to whether South Korea’s launch of the KSLV-1 (Naro-1) rocket succeeded in placing a satellite into orbit last night:
South Korea had been claiming they had placed their STSAT-2 scientific satellite into orbit on Tuesday, following its launch on their KSLV-1 (Korea Satellite Launch Vehicle) â€œNaroâ€ rocket. However, Russian officials cited by â€œInterfaxâ€ are claiming the vehicle failed during second stage flight. The launch came after last weekâ€™s scrub â€“ caused by a problem during the automated launch sequence, relating to pressurization issue.
The first stage is Russian built; the second was produced in South Korea.
The Hankyoreh has a Q&A interview with KSLV-1 Team Leader Park Jung-joo.
Q: What has Korea gained from technological cooperation with Russia?
A: â€œIf we had tried [to develop the Naro] with our own strength alone, it would have been a formidable task. The first stage was produced by Russia, but we also participated in designing the launch vehicle system and built the launch pad, and Korean businesses participated and designed the orbit and so on. So we were able to gain experience and technology in a wide range of areas. Our engineers all got some experience, and so they realized we can do it ourselves next time. This is important.â€
Contrary to the Korean governmentâ€™s claim of working together with Russia to develop the phase-one liquid-fuel rocket, Russia is spearheading the project while Korea has just bought the technology. Seoul says it will develop itself 80 percent of the technologies related to the launch pad, but Moscow has apparently declined to hand over design blueprints for the core technology.
The Korean government began the project to develop the rocket in 2002 even without the required technology. It envisioned buying advanced technology or taking a â€œquantum jumpâ€ by unofficially getting the technology from others. Russia, an advanced power in launch vehicle technology with whom Korea forged a partnership in 2005, has not transferred the technology. The Space Technology Protection Treaty signed between both sides at Russiaâ€™s request bans the transfer of technology on liquid fuel-powered engines, and has thus deepened Korean dependence on Russian technology. Support for research and development and political and diplomatic efforts are urgently needed to ensure that Korea catch up in space technology and secure technological independence.
Glitch forces SKorea to abort rocket launch The Associated Press
A technical glitch forced South Korea to abort liftoff of its first rocket into space Wednesday, delaying a launch that threatened to heat up tensions with rival North Korea even as they joined in mourning the death of an ex-president who pushed tirelessly for reconciliation.
Judging from what I’m seeing from Korean television, the launch of South Korea’s first rocket has been scrubbed. The countdown has been stopped. And the launch tower, which had been lowered for the launch, has been raised back up to the rocket. No word on why yet. At least none that I can decipher.
There’s an interesting sidelight to Wednesday’s upcoming launch of South Korea’s first rocket, KSLV-1 (Nano-1), that gives some valuable insights into how Russia conducts its space business.
The Russian-made lower-stage is actually the first stage of that nation’s new Angara family of rockets. The Korean government paid for the development, although the Russians are not sharing any of the technical details with them. (The Koreans have built the KSLV’s second stage using their own technologies.)
Peter J. Brown has a great analytical piece about South Korea’s new Naro-1 (KSLV-1) rocket, which is set for its inaugural launch in the next week.
Brown delves into Seoul’s prickly 6-year partnership with the Russians, who built the first stage of the two-stage vehicle. Despite being on the verge of the first launch, the relationship with Russia has soured a bit over delivery delays and by Khrunichev’s refusal to share information about the first stage due to tech transfer concerns.
