Abstract

By providing an environment where energetic particles and micrometeorites can not penetrate, caves on Mars may serve as a human shelter in future Mars explorations. More than 1,000 cave entrance candidates have been detected; however, their physical characteristics that can be utilized in detecting more candidates have not been explored in detail. In this paper, we explore the nighttime temperature of 100 cave entrance candidates and their surrounding areas to investigate 1) the nighttime temperature tendencies relative to their surrounding areas and 2) the extent of these temperature differences. We find that 79% of the cave entrance candidates exhibit higher temperatures than the surrounding areas, and 59% show a temperature difference over 20K, suggesting that the cave entrances may generally show higher temperatures than the surrounding areas during the nighttime.

火星上潜在洞穴夜间温度特征的研究

通过提供一个高能粒子和微陨石无法穿透的环境，火星上的洞穴可能在未来的火星探索中成为人类的避难所。目前已发现1000多个候选洞口;然而，它们的物理特性可以用来探测更多的候选者，但尚未得到详细的探讨。本文对100个候选洞口及其周边地区的夜间温度进行了研究，以研究1)相对于其周边地区的夜间温度趋势和2)这些温度差异的程度。我们发现，79%的候选洞穴入口温度高于周围地区，59%的洞穴入口温度差异超过20K，这表明洞穴入口在夜间可能普遍高于周围地区。

期刊介绍： JASS aims for the promotion of global awareness and understanding of space science and related applications. Unlike other journals that focus either on space science or on space technologies, it intends to bridge the two communities of space science and technologies, by providing opportunities to exchange ideas and viewpoints in a single journal. Topics suitable for publication in JASS include researches in the following fields: space astronomy, solar physics, magnetospheric and ionospheric physics, cosmic ray, space weather, and planetary sciences; space instrumentation, satellite dynamics, geodesy, spacecraft control, and spacecraft navigation. However, the topics covered by JASS are not restricted to those mentioned above as the journal also encourages submission of research results in all other branches related to space science and technologies. Even though JASS was established on the heritage and achievements of the Korean space science community, it is now open to the worldwide community, while maintaining a high standard as a leading international journal. Hence, it solicits papers from the international community with a vision of global collaboration in the fields of space science and technologies.
