超级军网飞向火星的窗口是怎么会事

昨天看到新闻里播放美国的火星探测器飞往火星，但是前段时间俄罗斯出问题的火星探测器又说过了火星发射窗口去不了火星了，这是怎么回事？昨天看到新闻里播放美国的火星探测器飞往火星，但是前段时间俄罗斯出问题的火星探测器又说过了火星发射窗口去不了火星了，这是怎么回事？
同问，三楼你说呢？
每26个月地球跟火星会处于最近位置，在这段时间内发射可以节省燃料……
Phobos-Grunt和MSL选择的trajectory不同，因此窗口时间略有不同。前者是type II，时间长，但需要的delta-v小；后者是type I，与Type II恰好相反，如果留意两者的预计到达日期，你会发现MSL是后发先至

谢谢，也就是说俄罗斯的探测器没戏了？

去火星是不可能了，如果硬件没有问题的话可能考虑去某颗近地小行星
The deputy head of the Phobos-Grunt project chief scientist, Alexander Zakharov of the Space Research Institute, said the telemetry would show whether the spacecraft could be "reanimated" and used in another research mission.
He said that if the spacecraft is fully operational, the best scientific mission for it would be to study a near-earth asteroid.
"A research of an asteroid is more reminiscent of our initial task than Moon research. The Phobos itself is more like an asteroid and scientific equipment was made for that purpose," he said

只是示意，实际上飞往火星的探测器是曲线轨迹与火星交汇的。（靠行星引力慢腾腾飞往火星的飞行器除外）
