- 温奇康贝陨石于2021年2月28日坠落，是英国30年来第一颗回收的陨石，也是英国第一颗碳质球粒陨石。陨石被流星摄像机网络、门铃摄像机和目击者广泛观察，并在其坠落后12小时内迅速收集到213.5克（约为最终回收质量的35%）。因此，它代表了一个研究非常原始的外星物质的机会，需要适当的精心策划。陨石落在一个狭窄的（600米宽）散落的领域约8. 5公里长，取向约东西，最大的单一碎片在最远（东）端的温奇康贝镇，格洛斯特郡。在已知的602克总质量中，约525克在伦敦自然历史博物馆展出。在秋季的一个月内制定了一项样本分析计划，使英国及其他地区的科学家能够快速获取和分析新材料。将样品长期储存在氮气气氛手套箱中。初步的宏观和电子显微镜检查显示它是一个CM2球粒陨石，尽管早期的搜索，没有脆弱的矿物，如岩盐，硫等，观察了
– The Winchcombe meteorite fell on February 28, 2021 and was the first recovered meteorite fall in the UK for 30 years, and the first UK carbonaceous chondrite. The meteorite was widely observed by meteor camera networks, doorbell cameras, and eyewitnesses, and 213.5 g (around 35% of the final recovered mass) was collected quickly — within 12 h — of its fall. It, therefore, represents an opportunity to study very pristine extra-terrestrial material and requires appropriate careful curation. The meteorite fell in a narrow (600 m across) strewn field ~ 8.5 km long and oriented approximately east – west, with the largest single fragment at the farthest (east) end in the town of Winchcombe, Gloucestershire. Of the total known mass of 602 g, around 525 g is curated at the Natural History Museum, London. A sample analysis plan was devised within a month of the fall to enable scientists in the UK and beyond to quickly access and analyze fresh material. The sample is stored long term in a nitrogen atmosphere glove box. Preliminary macroscopic and electron microscopic examinations show it to be a CM2 chondrite, and despite an early search, no fragile minerals, such as halite, sulfur, etc., were observed.
