The fifth launch of Korea's homegrown Nuri rocket has been postponed until October due to problems with thrusters on nanosatellites to be carried aboard the vehicle, officials said Sunday.
According to the Korea AeroSpace Administration (KASA) and the Korea Advanced Institute of Science and Technology (KAIST) Satellite Technology Research Center, the launch was delayed from its original schedule to allow time for replacing and testing underperforming thrusters on some nanosatellite payloads.
Thrusters provide the propulsion needed for satellites to adjust or maintain their orbits and are key components for nanosatellites that fly in formation while maintaining fixed intervals.
"There were some areas where the thrusters' performance fell short of expectations," said Kim Jin-hee, director general of the Satellite Directorate at KASA. "We have completed the necessary improvements to enhance stability."
