South Korean rocket ”Nuri” completes flight... 13 satellites launched into space

The South Korean rocket "Nuri" launched a total of 13 satellites, including medium-sized ones, into space. The Korea Aerospace Administration and the Korea Aerospace Research Institute announced the launch at 1:13 a.m. on the 27th at the Naro Space Center in Goheung County, South Jeolla Province.
The fourth wrap-up party for "Nuri" was held at the event. It was the first in about two and a half years since the third wrap-up party in May 2023.
The launch management committee, which met at 7:30 pm on the 26th, decided to launch the main payload, the Next Generation Medium Satellite.
In order for Seong-3 to enter the target orbit, a comprehensive review was conducted of Nuri's technical readiness, the weather and space environment, and the possibility of a collision with a space object, and the wrap-up party time was set at 12:55 a.m. on the same day.
After the decision was made, the procedures for loading oxidizer and fuel, withdrawing the launch vehicle erector, starting the alignment of the inertial navigation guidance system, and withdrawing the launch vehicle erector were carried out in sequence.

Just before the launch of the rocket (PLO), an abnormal signal was detected in the umbilical recovery pressure sensor, and the wrap-up party was held 18 minutes late. After the rocket liftoff, the first stage was separated, followed by the first stage separation, the second stage separation, and the third stage separation.
After separating the Next Generation Medium-sized Satellite 3 at a target altitude of 600 km, the CubeSats were separated in groups of two, a total of six times.
According to both agencies, the flight of Nuri ended at 1:31 a.m.
"The Nuri and 12 cube satellites were successfully launched," the statement said. "Researchers from the Korea Aerospace Research Institute are currently analyzing the Nuri's flight data, and the data analysis is expected to take about 40 minutes."
