SEOUL, Oct. 6 (Yonhap) -- South Korea's homegrown Nuri rocket was moved to a launchpad and raised into a vertical position Tuesday, a day before its scheduled fifth launch, the country's space agency said.

The Korea AeroSpace Administration (KASA) said the launch team completed transporting the rocket to the launchpad at the Naro Space Center in Goheung, about 330 kilometers south of Seoul, at 7:30 a.m. after a 90-minute journey from the assembly complex.

The rocket was erected vertically and secured in place at 10:35 a.m., according to the Korea Aerospace Research Institute.

The launch team connected the rocket to the umbilical systems, which supply power and other necessary connections, and conducted a series of checks in preparation for fueling, completing the work at 8:05 p.m.

KASA will convene a launch management committee at 8 a.m. Wednesday to determine the final launch time after reviewing the rocket's technical readiness, weather conditions and the possibility of collisions with space objects. The final launch time will be announced at 8:45 a.m.

The payload consists of five New-space Earth Observation Satellite Constellation for National Safety (NEONSAT) microsatellites, which will form part of South Korea's first domestically launched microsatellite constellation, as well as 10 CubeSats.

The fifth flight will mark Nuri's first attempt to sequentially deploy multiple primary satellites designed to carry out the same mission.

About four hours before liftoff on Wednesday, the launch team will begin filling the three-stage rocket with kerosene fuel and liquid oxygen oxidizer after completing system checks.

The five NEONSATs, Nos. 2 through 6, will be deployed at intervals of 35 to 40 seconds at an altitude of around 575 km. The 10 CubeSats will then be deployed two at a time at 10-second intervals.

The NEONSATs will conduct high-frequency monitoring of the Korean Peninsula and surrounding areas for national security and disaster response.

The constellation will eventually consist of 10 satellites, with another five to be launched aboard Nuri's sixth flight scheduled for next year.

Once fully operational, the constellation will be capable of imaging the Korean Peninsula more than three times a day and revisiting the same location within 24 hours.

首尔，10 月 6 日（韩联社）——韩国航天局表示，韩国自主研发的“努里”火箭于周二被运至发射台并竖立起来，比原计划的第五次发射提前一天。

韩国航天局（KASA）表示，发射团队于早上 7:30 完成了将火箭从组装厂运送到位于首尔以南约 330 公里的强兴市罗老航天中心发射台的工作，全程耗时 90 分钟。

据韩国航空航天研究院称，火箭于上午 10:35 垂直竖立并固定到位。

发射团队将火箭连接到脐带系统（该系统提供电力和其他必要的连接），并进行了一系列检查，为加注燃料做准备，工作于晚上 8 点 05 分完成。

韩国航天局将于周三上午8点召开发射管理委员会会议，在评估火箭的技术准备情况、天气状况以及与太空物体碰撞的可能性后，确定最终发射时间。最终发射时间将于上午8点45分公布。

有效载荷包括五颗用于国家安全的新型地球观测卫星星座（NEONSAT）微型卫星，它们将成为韩国首个国产微型卫星星座的一部分，以及 10 颗立方体卫星。

第五次飞行将标志着努里首次尝试按顺序部署多颗旨在执行同一任务的主卫星。

周三发射前约四小时，发射团队在完成系统检查后，将开始向三级火箭内注入煤油燃料和液氧氧化剂。

五颗NEONSAT卫星（编号2至6）将在约575公里的高度上，以35至40秒的间隔依次部署。随后，10颗CubeSat立方体卫星将以10秒的间隔，每次部署两颗。

近地卫星将对朝鲜半岛及其周边地区进行高频监测，以保障国家安全和应对灾害。

该星座最终将由 10 颗卫星组成，另外 5 颗将搭乘 Nuri 号火箭的第六次飞行任务于明年发射升空。

一旦全面投入运行，该星座将能够每天对朝鲜半岛进行三次以上的成像，并在 24 小时内重访同一地点。
