摘　　要：经过几十年的发展,太阳的空间探测取得了巨大的成就。然而,极区磁场的演化和太阳子午流的反演一直受到投影效应的影响,同时太阳爆发中的电流片急需原位探测。因此,脱离黄道面的极轨探测和抵近太阳的“触摸”探测成为当前国际太阳物理领域急需发展的空间项目。鉴于极轨和抵近轨道的实施困难,低成本和高效的轨道部署方案是任务顺利执行的关键。提出一种新颖的利用特殊小行星入轨的方案。根据小行星数据库的资料,分别统计和分析了目前已发现的高倾角以及近日点靠近太阳的小行星的轨道参数,并提出了搭载小行星的方案。该方案能够大大减少卫星入轨时间并节约成本,同时还可以与小行星探测相结合。如果项目得以实施,将是人类在利用小行星方面迈出的一大步。After decades of development,significant progress has been made in the field of space exploration of the Sun.However,studies on the evolution of polar magnetic fields and the inversion of the solar meridional flows have been persistently affected by projection effects.Additionally,the in-situ detection of current sheets in solar eruptions remains an urgent and demanding task.Consequently,polar detection from out of the ecliptic plane and closer detection to“touch”the Sun have become urgent space projects in the international solar communities.However,implementing polar and closer detection orbits presents several challenges,making low-cost and efficient orbital deployment schemes essential to the successful execution of the mission.In this article,we propose a novel scheme involving the use of some special asteroids for orbital insertion.We analyze the orbital parameters of high-inclination and near-sun asteroids in the asteroid database and develope an approach for satellites to take on them.Following this approach,the time for satellites to get into orbit can be significantly reduced and costs can be greatly saved,while it can be combined with the asteroid exploration.If implemented,this project would also represent a significant step forward for humans in utilizing the resources of asteroids.
