Reasons for KSLV-1 delivery vehicle failure still unknown

August 16th, 2010


Russia and South Korea will continue to investigate the abortive launch of the KSLV-1 delivery vehicle, whose first stage was made in Russia, Khrunichev Aerospace Center press secretary Alexander Bobrenyov told Interfax-AVN.

“The joint commission has approved additional tests for exposing reasons of the unsuccessful rocket launch,” he said. “The commission did not discuss the possibility of an additional launch.”

Meanwhile, an aerospace industry representative told Interfax-AVN that additional tests were a compromise that satisfied both countries.

Telemetric data convinced Russia that the first stage of the rocket had nothing to do with the accident.

“The entire information was spelled out to the Korean partners, but they demanded an additional probe,” he said.

The commission studying the KSLV-1 failure held the third meeting in the South Korean city of Taejon.

Khrunichev General Director Vladimir Nesterov said on July 15 that the commission had not found any problems with the rocket’s first stage.

The first launch of a KSLV-1 took place at the Naro Space Center in South Korea on August 25, 2009. The first stage created at the Khrunichev operated normally. Yet half of the nose fairing failed to separate and the satellite was not put into the designated orbit.

The second launch was done on June 10, 2010. It was also a failure.
