摘要:

斯普特尼克平原,冥王星的巨大冰川,承载着许多科学之谜,包括数千个细长的坑结构的存在。我们研究了新视野号数据集中这些坑结构的各种属性,揭示了它们的长度,长宽比和方向特性;我们还研究了它们的内部反射率,颜色和成分,并将这些属性与冥王星上的其他一些相关区域进行了比较。然后,我们评论的起源机制的坑,也失踪的挥发物的命运代表的坑上斯普特尼克平原。

英文摘要:

Sputnik Planitia, Pluto's gigantic ice glacier, hosts numerous scientific mysteries, including the presence of thousands of elongated pit structures. We examine various attributes of these pit structures in New Horizons data sets, revealing their length, aspect ratios, and orientation properties; we also study their interior reflectivities, colors, and compositions, and compare these attributes to some other relevant regions on Pluto. We then comment on origin mechanisms of the pits and also the fate of the missing volatiles represented by the pits on Sputnik Planitia.
