GOHEUNG, South Korea, Oct. 7 (Yonhap) -- South Korea's homegrown Nuri rocket placed 15 satellites into orbit on its fifth launch, including five that will form part of the country's first domestically launched microsatellite constellation, the nation's space agency said.

The 200-ton Nuri blasted off from the Naro Space Center in Goheung, about 400 kilometers south of Seoul, at 12:25 p.m. and completed its flight 20 minutes later.

The payload consists of five New-space Earth Observation Satellite Constellation for National Safety (NEONSAT) microsatellites and 10 CubeSats.

Nuri successfully separated its first and second stages before releasing the satellites at an altitude of around 575 km.

The five NEONSATs, Nos. 2 through 6, each weighing less than 100 kilograms, were deployed at intervals of 35 to 40 seconds, with Nuri's upper stage rotating about 45 degrees between each separation to prevent collisions. The 10 CubeSats followed in pairs every 10 seconds.

"The Nuri rocket reached its intended orbit as planned," said Oh Tae-seok, administrator of the Korea AeroSpace Administration (KASA), adding that the launch team is conducting a detailed analysis to confirm whether the satellites were successfully deployed.

After releasing all 15 satellites, Nuri performed a collision-avoidance maneuver and vented its remaining fuel, completing its flight. The rocket will remain in orbit before eventually reentering Earth's atmosphere and burning up.

The Korea Aerospace Research Institute will track the flight from facilities in South Korea and Palau in the western Pacific.

The fifth flight marks Nuri's first attempt to sequentially deploy multiple primary satellites designed to perform the same mission.

Each NEONSAT weighs less than 100 kilograms and carries an electro-optical camera capable of distinguishing objects as small as 1 meter in black-and-white images and 4 meters in color images.

The satellites will monitor the Korean Peninsula and surrounding areas for national security and disaster response.

The NEONSAT constellation will eventually consist of 10 satellites. Another five will be launched aboard Nuri's sixth flight scheduled for next year to complete the constellation.

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.

韩国高兴，10月7日（韩联社）——韩国航天局表示，韩国自主研发的“努里”火箭在第五次发射中将15颗卫星送入轨道，其中包括5颗将组成韩国首个国产微型卫星星座的卫星。

重达 200 吨的 Nuri 火箭于下午 12 点 25 分从首尔以南约 400 公里的强兴市罗罗航天中心发射升空，20 分钟后完成飞行。

有效载荷包括 5 颗用于国家安全的新型空间地球观测卫星星座 (NEONSAT) 微型卫星和 10 颗立方体卫星。

努里火箭成功分离了第一级和第二级，然后在约 575 公里的高度释放了卫星。

五颗NEONSAT卫星（编号2至6）每颗重量均不足100公斤，它们以35至40秒的间隔依次部署。努里火箭的上级在每次分离之间旋转约45度，以防止碰撞。随后，十颗CubeSat立方体卫星以每两颗为一组，每隔10秒部署一颗。

韩国航空航天局（KASA）局长吴泰锡表示：“努里火箭按计划进入了预定轨道。”他还补充说，发射团队正在进行详细分析，以确认卫星是否成功部署。

在释放全部15颗卫星后，努里火箭进行了避碰机动并排出剩余燃料，完成了飞行任务。火箭将在轨道上运行一段时间，最终重返地球大气层并烧毁。

韩国航空航天研究院将从位于韩国和西太平洋帕劳的设施跟踪此次飞行。

第五次飞行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。

每颗 NEONSAT 的重量不到 100 公斤，并搭载一台光电相机，能够分辨黑白图像中小至 1 米的物体和彩色图像中小至 4 米的物体。

这些卫星将监测朝鲜半岛及周边地区，以维护国家安全和应对灾害。

NEONSAT星座最终将由10颗卫星组成。另外5颗卫星将搭乘努里号火箭的第六次飞行任务（计划于明年进行）发射升空，以完成星座的建设。

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。
