Abstract

The optimal trajectories of the mission to the “hazardous” asteroid Apophis, designed to study the asteroid, taking samples of its soil and returning to the Earth, are constructed and analyzed. The scheme of transfer with applying chemical “high”-thrust jet propulsion systems is used. For the transfer to the asteroid in 2019–2022, with the total mission duration being up to two years, the optimal-in-payload-mass, three-impulse trajectories of spacecraft, are obtained. The principal possibility of accomplishing the Earth–Apophis–Earth space mission, based on launch vehicles (LVs) of “Soyuz” type and “Fregat” upper stage, during the transfer in 2019–2022, is demonstrated.

高推力飞行下地球-小行星-地球任务的最佳轨迹的构建

摘要

构造和分析了“危险”小行星Apophis的最佳飞行轨迹，该轨迹旨在研究小行星，取样其土壤并返回地球。使用采用化学“高”推力喷射推进系统的传输方案。为了在2019-2022年间转移至小行星，任务总工期最长为两年，获得了航天器的有效载荷质量，三冲量轨迹。演示了在2019-2022年的转移期间，以“联盟号”型运载火箭和“弗雷加特”上级运载火箭为基础，完成地球-阿福非斯-地球太空任务的主要可能性。
