小天体探索还将继续,对C型小行星(162173)1999 JU3进行采样。尽管该任务和航天器可能会整合从隼鸟号任务中吸取的经验教训,但仍存在许多差异。为了最好地适应接近阶段,我们对 1999 JU3 和糸川(隼鸟任务的目标,将于 2010 年 6 月带样本返回)进行了比较,并展示了 1999 JU3 的动力学模拟。由于着陆器可能在即将到来的小型物体任务中发挥更重要的作用,因此我们还展示了部署和着陆的模拟,以及用于评估表面移动物体的性能和命运的基本表面动力学。结果表明,1999 JU3的中间区域可能是松散颗粒聚集的区域。最后,我们讨论了着陆器对目标重力模型和内部分布进行局部细化的科学机会。
The small body exploration is to be continued by going to take samples of the C-type asteroid (162173) 1999 JU3. Although the mission and spacecraft may integrate lessons learned from the Hayabusa mission, many differences exist. In order to best adapt the proximity phase, we give a comparison between 1999 JU3 and Itokawa, the target of the Hayabusa mission which is coming back in June 2010 with samples, and we show simulations of the dynamics of 1999 JU3. Since landers may take a more important role in the coming small body missions, we also show simulations of deployment and landing, as well as fundamental surface dynamics to assess performance and fate of moving objects on the surface. It is shown that intermediate regions of 1999 JU3 may be regions where loose particles gathered. Finally, we discuss lander science opportunity for local refinement of the target gravity model and internal distribution.
