Impressive track-stacks from our #GMN/#UKMeteorNetwork #RaspberryPi #MeteorCameras in #Oxfordshire 13/14 Dec '25. The satellite/aircraft trails are not counted as meteors; they were just in the frame at the same time as a meteor occurred #Geminids #Geminids2025 #MeteorShower #GeminidMeteors

Every space mission carries the potential to transform our understanding of life in the cosmos—yet 41 are at risk of cancellation.
