A Novel Scheme of Orbit Deployment for Polar and in Situ Detection of the Sun

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.
