月球和火星羽流效应的ISRU含意
ISRU Implications for Lunar and Martian Plume Effects
摘要：
实验、分析和模拟表明，一个足够大的火星着陆器的发动机排气羽流将在火星土壤中形成一个深的陨石坑，将喷出物吹到大约1公里的距离，用高动量的岩石撞击损坏着陆器的底部，并可能使着陆器倾斜，因为挖掘的洞在发动机关闭时坍塌成一个广泛的残留陨石坑。正因为如此，我们认为，我们将没有足够的安全裕度，以土地人类在火星上，除非我们机器人稳定土壤，形成原位着陆垫之前的任务。在恶劣的外星球环境中工作将需要大量时间来开发和认证新技术和现场着陆场建设程序。唯一能合理实现这一目标的地方是月球。
英文摘要：
Experiments, analyses, and simulations have shown that the engine exhaust plume of a Mars lander large enough for human spaceflight will create a deep crater in the martian soil, blowing ejecta to approximately 1 km distance, damaging the bottom of the lander with high-momentum rock impacts, and possibly tilting the lander as the excavated hole collapses to become a broad residual crater upon engine cutoff. Because of this, we deem that we will not have adequate safety margins to land humans on Mars unless we robotically stabilize the soil to form in situ landing pads prior to the mission. It will take a significant amount of time working in a harsh off-planet environment to develop and certify the new technologies and procedures for in situ landing pad construction. The only place to reasonably accomplish this is on the Moon.
