本文概述了实现人类小行星任务的战略方法，特别侧重于近距离操作。小行星表面给原位调查带来的风险和挑战迫使近距离操作由机器人探测器作为中介来完成。在这种结构中，一个前体提前数年被发送到潜在的目标小行星。它的主要目标是表征重力场和表面行为。如果找到合适的目标，载人任务就会继续进行。他们的主航天器在小行星周围的稳定轨道上运行，宇航员通过一个小型的非加压航天器被运送到小行星表面。他们在离火星表面几米的上空盘旋，部署并指挥小型机器人着陆器在火星表面执行科学操作。
This paper outlines the strategic approach to realize a human mission to an asteroid, focusing specifically on the proximity operations. The risks and challenges posed by asteroid surfaces to in-situ investigations force the proximity operations to be done by the intermediary of robotic explorers. In this architecture, a precursor is sent years in advance to a potential target asteroids. Its main goals are the characterization of the gravity field and of the surface behavior. If the target is found suitable, the manned mission then proceeds. With their main spacecraft stationed on a stable orbit around the asteroid, the astronauts are transported to the surface via a small, unpressurized spacecraft. Hovering a few meters above the surface, they deploy and command small robotic landers that perform scientific operations at the surface.
