explanation: '正确答案：D<br>解析：A.中星26与侦察卫星周期相同，并且当中星26在下半周运动时，卫星在上半周运动，故不可能相遇，故A错误；B.侦查卫星在D到A点过程中只有引力做功故机械能不变，故B错误；C.开普勒第二定律可知，在近地点速度大于远地点速度故中星26在C点线速度大于侦察卫星在D点线速度，故C错误；D.中星26与侦察卫星的周期相同，由开普勒第三定律，中星26轨道半径等于侦察卫星的半长轴，运动一个周期中星26是一个圆，而侦察卫星是一个椭圆，由于圆的面积大于椭圆的面积，故相等时间内中星26与地球的连线扫过的面积大于侦察卫星与地球的连线扫过的面积，故D正确；故答案为：D。'
