[다누리, 달 궤도에서 인공물 충돌 전후 포착!] 다누리가 8월 5일, 한국시간 15시 34분에 발생한 스페이스X 팰컨9 로켓 상단부의 달 표면 충돌 전후를 촬영했습니다! 다누리는 충돌 약 30분 전부터 관측을 시작해, 궤도 제어를 통해 충돌 지점 상공을 여러 차례 통과하며 총 8회에 걸쳐 촬영을 진행했습니다. 이번 관측을 통해 충돌 지점 주변의 지형 변화와 분출물 확산 흔적 등이 확인되었으며, 다누리는 충돌 전 기준 영상과 충돌 직후 영상을 모두 확보해 충돌로 인한 변화만을 분석할 수 있는 중요한 연구 자료를 마련했습니다. 다누리가 확보한 관측 자료는 NASA 달 정찰 궤도선(LRO)의 후속 관측과 연계되어 국제 공동 연구에 활용될 예정입니다 :) #한국항공우주연구원 #항우연 #KARI #다누리 #KPLO #달탐사 #SpaceX #팰컨9 #달충돌

Our team at @iaa_csic has captured the impact on the Moon of the upper stage of a Falcon 9 rocket. We attach a preliminary video showing the evolution of the ejected material.

🚨 Spaceflux observed Russia’s Cosmos 2553 tumbling in orbit. Brightness varied by 0.7–3 mags, indicating a ~2.2s spin period. Optical sensing reveals behavior radar can't see, real-time insights for space security. 🛰️

The first videos of the #asteroid #C0WEPC5 entry in #Russia are coming out on @telegram . It appears to be very similar to previous asteroid entires (2022 WJ, 2023 CX1, 2024 BX1). Lots of fragments at the end, it probably dropped some rocks in a remote forested area.

Following the anomaly reported by Eutelsat on 31 Jan, Spaceflux has been monitoring EUTELSAT 113 WEST A. On Feb 2, our measurements detected large fluctuations in brightness, indicating problems with attitude control. See the video below capturing these variations over 5 min.
