Hyundai Rotem's Space Roadmap(They're challenging the field of future reusable launch vehicles, I suppose.) and HCM Technology Overview

 

[urban mine]

INNOSPACE announced today that it has begun functional checks and satellite–launch vehicle interface tests for customer satellites and experimental payloads as part of the operational procedures for its first commercial launch mission SPACEWARD of the ‘HANBIT-Nano’.


This procedure verifies the electrical and mechanical connections between the payload adapter (PLA) and other integration hardware with the satellites and payloads. It is an essential pre-launch step to ensure stable mounting and integrated operation.

I recall that the previous TLV launch also experienced repeated delays.

[Nuri's 4th Launch] Nuri Succeeds in First Launch Led by Private Sector

The fourth launch of 'Nuri,' the Korea Space Launch Vehicle developed with South Korea's own technology, has succeeded. This launch, the first to be led by the private sector, is expected to be a star

The fourth launch of 'Nuri,' the Korea Space Launch Vehicle developed with South Korea's own technology, has succeeded. This launch, the first to be led by the private sector, is expected to be a starting point for the flourishing of the domestic space industry.

It also signifies that payloads and space technologies, painstakingly developed by dozens of domestic industry-academia-research institutes, can now be fully verified using a domestic launch vehicle. The success was achieved despite a 2.5-year launch hiatus. This is a green light for securing Nuri's reliability.

The Korea AeroSpace Administration (KASA) announced that the Next-Generation Medium Satellite 3 (CAS500-3), launched aboard the Korean launch vehicle Nuri at 1:13 AM on the 27th (KST), successfully reached its target orbit. Furthermore, two-way communication with the King Sejong Station ground station in Antarctica was successfully established around 1:55 AM. Communication with five of the twelve secondary/piggyback satellites launched alongside it has also been confirmed.

First, following the initial contact, CAS500-3 achieved an additional successful communication around 2:48 AM via the antenna at the KARI (Korea Aerospace Research Institute) ground station in Daejeon. To date, the satellite has conducted two-way communication twice with the KARI ground station and 12 times with overseas ground stations (King Sejong Station in Antarctica, and Svalbard in Norway).

During the communication sessions today, the functionality of the CAS500-3 main body components was confirmed. Detailed status information will be downloaded, and precision checks will be performed through additional communications with the Daejeon KARI ground station and others.

Following a two-month period of initial operation, the satellite will undergo payload checks and mission preparation. It will then enter full-scale space science mission activities for one year, orbiting the Earth approximately 15 times a day in a Sun-Synchronous Orbit .

CAS500-3 is equipped with the following payloads to perform space science and technology verification missions:

BioCabinet: Verification of 3D differentiation and culture of stem cells based on bio 3D printing.

IAMMAP : Space plasma-magnetic field measurement instrument.

ROKITS : Space-based wide-field airglow observation instrument.

In addition, the development organizations responsible for the 12 secondary/piggyback satellites have initiated initial ground station communication and performance checks.

Among the 12 secondary satellites, five satellites—manufactured by the Electronics and Telecommunications Research Institute (ETRI), Cosmoworks, Inha University, and KAIST—have also completed communication with their respective ground stations.

Following the joint final avionics integration test conducted with the Brazilian Air Force (FAB) at the Alcântara Space Center on November 23, we have completed all enhancements to the signal-processing system for HANBIT-Nano.

①누리호 탑재 중량 2.2톤으로 늘어…유럽 발사체 맞먹는 기술 진화

“모두 고생 많으셨습니다.” 27일 새벽 전남 고흥군 나로우주센터 발사통제동의 발사지휘센터(MDC)와 발사관제센터(LCC)에서는 한국항공우주연구원과 한화에어로스페이스 등 누리호 4차 발사 임무의 핵심 관계자 60여

The Nuri rocket has demonstrated the proven performance capability of launching a payload weighing 2.2 tons into a Sun-Synchronous Orbit (SSO) at an altitude of 600 to 700 kilometers. The technological maturity level has progressed from a 1.5-ton capacity in the first launch in 2021, through a 1.9-ton capacity, and finally achieving the 2.2-ton class over four consecutive launches.

This Nuri rocket's flight time was slightly shorter than initially planned, and as it demonstrated a commensurately higher engine thrust, the effective payload capacity is expected to be more than 2.2 tons. The official thrust of the Nuri rocket is 300 tons based on the first-stage engine, but it was reportedly a few percent stronger in this launch. KARI (Korea Aerospace Research Institute) plans to find the exact reason through data analysis, but initially, the influence of the launch vehicle manufacturing quality, handled by Hanwha Aerospace, is being cited. Department Manager Choi Chang-ho said, "Just like cars or electronics, the actual quality of a launch vehicle can vary depending on manufacturing capabilities," adding, "It seems Hanwha Aerospace produced a high-quality product."
