Our understanding of the Solar System is based on a foundation of meteorite analyses. Knowing their orbital origin provides a critical spatial context, but we have this data for <0.1% of samples. This project aims to address this issue. There are 66 meteorite falls across Australia with orbits determined by the Desert Fireball Network that await recovery - more than the current global dataset. This project expects to generate new knowledge by applying an innovative search methodology using drones and machine learning. Expected outcomes include dramatically increasing the number of orbital meteorites. This should provide significant benefits. By linking meteorites to their parent asteroids every rock becomes a small sample-return mission.

我们对太阳系的了解是建立在陨石分析的基础上的。了解它们的轨道原点提供了关键的空间背景，但我们拥有 <0.1% 的样本的数据。该项目旨在解决这个问题。澳大利亚各地有 66 块陨石坠落，其轨道由沙漠火球网络确定，等待回收——比当前的全球数据集还要多。该项目希望通过使用无人机和机器学习的创新搜索方法来产生新知识。预期结果包括大幅增加轨道陨石的数量。这应该会带来显着的好处。通过将陨石与其母体小行星联系起来，每块岩石都成为一个小型样本返回任务。
