土星探测器

在土星探测器的轨道设计和计算中，充分利用了有关天体的引力机动，有目的地使探测器飞过一系列行星来增加探测器的能量，从而大大降低了探测器的发射条件。

In the design and computation of orbit of Saturnian explorer , the author fully utilizes the gravitational force of some celestial bodies , thus reducing greatly the launching conditions .

根据牛顿第二定律和万有引力定律，建立了空间探测器的运动微分方程，并以土星探测器为例，利用精确的数值积分方法对其轨道进行了设计和计算。

This paper establishes the differential equations of motion of space explorer according to the Newton 's Laws of Motion and the universal gravitation , computes the flying orbit of Saturnian explorer , taking the Saturnian explorer as the computational example and using accurate numerical integration method .

现在正环绕土星的卡西尼无人探测器为这些现象给出了证据。

Evidence for this has come from the robot Cassini spacecraft now orbiting Saturn .
