全球火球观测站
A Global Fireball Observatory
摘要：
世界上的陨石收藏包含了非常丰富的早期太阳系是由什么组成的图片，然而，这些样本缺乏与其母体人口相关的空间背景是一个问题。小行星群的表面矿物同样丰富，将这两个种群（陨石和小行星）一起绘制是行星科学的一个重大挑战。直接探测小行星的成本很高。另一方面，观测陨石坠落并计算它们在大气层前的轨道是解决这个问题的一种更便宜的方法。全球火球观测站（GFO）合作成立于2017年，汇集了多个机构（来自澳大利亚，美国，加拿大，摩洛哥，沙特阿拉伯，英国和阿根廷），以最大限度地提高火球观测时间和陨石回收率。成员可以选择独立运作，但也可以选择与其他GFO合作伙伴充分合作。这种有效的方法利用了从澳大利亚沙漠火球网络（DFN）探路者项目中获得的经验。最先进的技术（DFN相机系统和数据简化）和支持团队的经验在所有合作伙伴之间共享，从而为科学调查和陨石搜索腾出时间。随着所有网络的结合，截至2019年年中，GFO合作已经覆盖了地球表面0.6%的陨石回收，并计划在21世纪20年代初达到2%。我们估计，经过5年的运行，GFO将观察到几乎每一种陨石类型的火球。这一共同努力将为实验室带来新的、新鲜的、外星物质，从而对太阳系的形成产生新的见解。
英文摘要：
The world's meteorite collections contain a very rich picture of what the early Solar System would have been made of, however the lack of spatial context with respect to their parent population for these samples is an issue. The asteroid population is equally as rich in surface mineralogies, and mapping these two populations (meteorites and asteroids) together is a major challenge for planetary science. Directly probing asteroids achieves this at a high cost. Observing meteorite falls and calculating their pre-atmospheric orbit on the other hand, is a cheaper way to approach the problem. The Global Fireball Observatory (GFO) collaboration was established in 2017 and brings together multiple institutions (from Australia, USA, Canada, Morocco, Saudi Arabia, the UK, and Argentina) to maximise the area for fireball observation time and therefore meteorite recoveries. The members have a choice to operate independently, but they can also choose to work in a fully collaborative manner with other GFO partners. This efficient approach leverages the experience gained from the Desert Fireball Network (DFN) pathfinder project in Australia. The state-of-the art technology (DFN camera systems and data reduction) and experience of the support teams is shared between all partners, freeing up time for science investigations and meteorite searching. With all networks combined together, the GFO collaboration already covers 0.6% of the Earth's surface for meteorite recovery as of mid-2019, and aims to reach 2% in the early 2020s. We estimate that after 5 years of operation, the GFO will have observed a fireball from virtually every meteorite type. This combined effort will bring new, fresh, extra-terrestrial material to the labs, yielding new insights about the formation of the Solar System.
