通过对20世纪60年代和70年代“阿波罗”号和“月球”号从月球带回的样本进行分析，我们对太阳系内部起源和演化的理解取得了重大进展。最近，“星尘”号和“创世纪”号分别对彗星颗粒和太阳风粒子进行了采样，揭示了它们的元素和同位素组成。同样，隼鸟号从近地小行星25143 Itokawa带回的样本使我们能够深入了解太阳系小天体的风化层演化，并首次提供了陨石和小行星之间的直接联系。在我们写这篇社论的时候，隼鸟二号在采集了小行星162173龙宫的样本后正在返回地球，而奥西里斯-雷克斯正准备从小行星101955本努收集样本，嫦娥五号在中断了40多年后正准备从月球上采集机器人样本。事实上，美国宇航局最近宣布了ARTEMIS计划，目标是在2024年之前将第一位女性和下一位男性送上月球
Major advances in our understanding of the origin and evolution of the inner Solar System have been made through analyses of samples from the Moon returned by the Apollo and Luna missions in 1960s and 1970s. More recently, the Stardust and Genesis missions sampled cometary grains and solar wind particles, respectively, revealing their elemental and isotopic compositions. Similarly, samples returned by the Hayabusa mission from the near-Earth asteroid 25143 Itokawa enabled insights into regolith evolution on minor bodies in the Solar System and provided the first direct link between meteorites and asteroids. As we write this editorial, Hayabusa2 is on its return journey to Earth after having sampled asteroid 162173 Ryugu while OSIRIS-REx is preparing to collect samples from asteroid 101955 Bennu and Chang’E-5 mission is being readied for a robotic sample return from the Moon after a hiatus lasting over 4 decades. Indeed, NASA’s recently announced ARTEMIS program with the aim of landing the first woman and the next man on the Moon by 2024
