Question: What are the stages of development of South Korean missile science?

Korea Space Launch Vehicles :

Korea Space Launch Vehicle-1 (KSLV-1), also called Naro, series of South Korean launch vehicles that were designed to launch Earth-orbiting satellites and that brought South Korea into the club of space nations.

The KSLV-1 is 33 metres (108 feet) tall and 3.9 metres (12.8 feet) in diameter.

It has two stages:

1- a liquid-fueled first stage developed in Russia by the Khrunichev State Research and Production Space Center and a solid-fueled.

2- second stage developed by the Korea Aerospace Research Institute.

The KSLV-1 is designed to lift up to 100 kg (220 pounds) to low Earth orbit.

---------------------------

Question: Talk in detail about the first stage in Korean rocket science? To what extent did Russia contribute to this?

* The first launch of the KSLV-1 was intended to place South Korea’s first satellite, Science and Technology Satellite-2A (STSAT-2A), into orbit.

* The launch took place on August 25, 2009, at the Naro Space Center in South Chŏlla (South Jeolla) province.

* After a successful first-stage ascent, one of the two payload fairings that covered the satellite failed to separate, and the second stage did not have enough fuel to overcome the additional weight.

* A second launch attempt, carrying STSAT-2B, took place on June 10, 2010.

On that occasion the vehicle exploded, slightly more than two minutes into its first-stage ascent.

* The third attempt, carrying STSAT-2C, on January 30, 2013, was successful, and the satellite was placed in a roughly 300-by-1,500-km (200-by-900-mile) orbit .

-------------------------------

South Korea faltered in its second attempt at rocket science on June 10, 2010 - and the third attempt on January 30, 2013. What were the reasons behind this?

* the reasons behind the failures of South Korea's second and third attempts at rocket science were different.

*** For the second attempt on June 10, 2010, the rocket carrying a climate observation satellite apparently exploded two minutes into its flight due to a malfunction in the electrical system of the first-stage booster

* The rocket was a joint project between South Korea and Russia, and the first-stage booster was designed and built by Russia's Khrunichev space production centre .

*** For the third attempt on January 30, 2013, the rocket successfully lifted off and deployed a scientific satellite, but the satellite failed to reach its intended orbit because of a problem in the fairing assembly.

** The fairing is a protective cover that shields the satellite from atmospheric friction during launch.

**The fairing was supposed to separate into two halves and fall away, but one of the halves did not detach properly and interfered with the satellite's orbital insertion,

The fairing assembly was also made by Russia.

** South Korea has been developing its own space launch vehicle since 2002, but faced political and technical challenges from the United States and North Korea.

** The US imposed restrictions on South Korea's rocket and missile development programs, fearing their possible connection to military ballistic missile programs ,

North Korea also condemned South Korea's space ambitions as a provocation and a violation of UN resolutions ....
