Happy to announce that my book is out: STELLE NERE bit.ly/3BGRrmR 𝐒𝐭𝐞𝐥𝐥𝐞 𝐧𝐞𝐫𝐞 is the story of Eppe Loreta amateur astronomer from Bologna. one of the best visual observers of his generation who was almost completely forgotten due to his commitment to Fascism

A close encounter in orbit: Russian satellite Cosmos 2612 approached Finland’s ICEYE X36 to within just a few kilometres. @spacefluxHQ tracked the event from Chile, capturing both satellites in this remarkable animation. 🛰️ #SSA #SpaceDomainAwareness linkedin.com/posts/spaceflux…

[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

This feels like a good moment to remember a small tribute from a while back: in 2013 I dedicated an asteroid to Thomas Pynchon — (152319) Pynchon ¡VIVA LA REVOLUCIÓN! #pynchon #thomaspynchon #Oscars #onebattleafteranother @onebattlemovie it.wikipedia.org/wiki/152319…
