Russia needs 12–15 Soyuz launches to build its Starlink alternative

Russia will need between 12 and 15 successful launches of its Soyuz-2.1b rocket to assemble a minimum viable Rassvet satellite constellation, Ukrainian presidential adviser Serhii Beskrestnov said on Aug. 17.

Russia needs 12–15 Soyuz launches to build its Starlink alternative

Ukrainian presidential adviser Serhii Beskrestnov has stated that Russia will likely require between 12 and 15 successful launches of its Soyuz-2.1b rocket to construct a minimum viable Rassvet satellite constellation. Each Soyuz-2.1b can accommodate approximately 20 satellites in orbit. The Progress plant, which manufactures all the components of the Soyuz-2.1b except the engines, has been targeted by Ukrainian forces.

However, the full impact of this damage is still uncertain, according to Beskrestnov. Disrupting production on a substantial scale would necessitate considerable effort, as finished components may be stored at cosmodromes or in transit. While Russia also possesses an Angara-A5 rocket, manufactured in Omsk and launched less frequently (approximately once per year), it has a greater capacity, capable of launching about 60 satellites simultaneously.

The second group of communications satellites for the Rassvet project, designed to function similarly to SpaceX's Starlink, was launched on July 20. The initial satellites in the constellation were deployed in March.

Just by existing, they reduce roadkill...the 'benefit' of large predators 최근에 발표된 한 연구에 따르면, 늑대와 같은 대형 육식동물이 생태계에서 없어지면, 자동차에 의한 로드킬(roadkill)이 증가할 가능성이 있다는 것이 밝혀졌다. In a recently published study, it was found that the extinction of large carnivores such as wolves could lead to an increase in roadkill caused by cars. 서울대학교 공과대학 환경공학부 김태영 교수 연구팀은 2014년부터 2017년까지 한국에서 늑대와 같은 대형 육식동물이 생태계에서 사라진 후, 로드킬의 변화에 대해 분석했다. A research team led by Professor Tae-Young Kim from the Department of Environmental Engineering at Seoul National University's College of Engineering analyzed the changes in roadkill after the disappearance of large carnivores such as wolves from the ecosystem in Korea from 2014 to 2017. 연구팀은 한국에서 로드킬이 가장 많이 발생하는 고속도로 726km 구간을 대상으로, 2006년부터 2017년까지의 로드킬 데이터를 수집했다. The team collected roadkill data from 2006 to 2017 for a 726km section of highway in Korea where roadkill is most common. 분석 결과, 연구팀은 대형 육식동물이 사라진 후, 로드킬이 41% 증가했다고 밝혔다. As a result of the analysis, the team found that roadkill increased by 41% after the disappearance of large carnivores. 특히, 설치류의 로드킬이 64% 증가했는데, 이는 대형 육식동물이 설치류 개체수를 조절했던 것이 사라졌기 때문으로 추정된다. In particular, roadkill of rodents increased by 64%, which is thought to be due to the loss of large carnivores regulating rodent populations. 김태영 교수는 “이번 연구를 통해, 대형 육식동물이 생태계에서 차지하는 중요성을 다시 한번 확인했다”며 “향후, 생태계 복원 정책 수립시, 대형 육식동물 복원에 대한 고려가 필요하다”고 말했다. Professor Tae-Young Kim said, "Through this study, we have once again confirmed the importance of large carnivores in the ecosystem," and added, "In the future, consideration should be given to the restoration of large carnivores when establishing ecosystem restoration policies."
