移动的小行星表面侦察器（MASCOT）目前正在开发之中，作为德国航天中心对日本隼鸟2号使命的贡献，隼鸟2号是一个C型近地小行星1999 JU 3的取样返回使命。MASCOT是一个小的鞋盒大小的可展开包，总质量为10公斤。它利用跳跃机制重新定位，从不同的地面站点提供地面实况信息，从而增强了飞行任务的科学回报。因此，这是对样品返回使命的补充。MASCOT还将完成只能由表面元件提供的独立科学，并将作为侦察和侦察工具。设计小型着陆装置的挑战是这些物体的地质技术特性，这些特性基本上是先验未知的。形状和旋转状态被认为是不规则的，导致复杂的重力场，而表面特性甚至可能在一个小行星的表面上有很大的不同。环境条件的边际知识主要影响机动能力和制导控制性能。为了实现其使命目标，同时满足严格的质量和体积预算的限制，鉴于高度不确定的环境，MASCOT被设计为一个高度集成的小型着陆包，具有一定程度的自主机器人操作能力的小行星表面。本文介绍了MASCOT的系统设计以及有效载荷套件，然后重点介绍了使命设计方面和水面作战概念。据此，移动性子系统，姿态运动确定传感器和有效载荷的相互作用，由MASCOT的机载决策实体协调，进行了讨论。最后对功能端到端仿真和测试进行了展望。
The Mobile Asteroid Surface Scout (MASCOT) is currently under development as a DLR contribution to the Japanese Hayabusa 2 mission, a sample return mission to the C-type near-Earth asteroid 1999JU3. MASCOT is a small about the size of a shoe box deployable package with a total mass of 10 kg. It enhances the missions scientific return by providing ground truth information from different surface sites by relocating itself with a hopping mechanism. It is, thus, complementing the sample return mission. MASCOT will also accomplish stand-alone science which can only be provided by a surface element and will serve as reconnaissance and scouting vehicle. Challenges to the design of a small-body landing package are the geo-technical properties of these bodies, which are a priori basically unknown. The shape and rotational state is assumed to be irregular, resulting in a complex gravity field, whereas the surface properties could even differ largely across the surface of one asteroid. The marginal knowledge of the environmental conditions affects mainly the mobility capabilities and guidance control performance. To fulfill its mission objectives while satisfying the tight mass and volume budget constraints in view of a highly uncertain environment, MASCOT is designed as a highly integrated small landing package with some degree of autonomous robotic operations capability on the asteroid surface. This paper introduces the system design as well as the payload suite of MASCOT and then focuses on mission design aspects and the surface operational concept. Hereby, the interaction of the mobility subsystem, the attitude motion determination sensors and the payload, coordinated by MASCOT's onboard decision making entity, is discussed. An outlook to functional endto-end simulation and testing is given.
