刚刚排除技术故障的麦哲伦金星探测器又面临经费不足的困境。 1月4日,探测器A号发射机的调制出现故障,现在使用B号发射机,但B号机线路在一年前就产生啸声干扰。为了避开这一啸叫频谱,不得不降低数据传输速率,从218.8kbit/s降为115kbit/s。这样探测器每次飞越金星能收集到的数据减少了,1月底时,每圈轨道只有15分钟的测绘,覆盖了金星北纬17.6°～76°(包括马克斯韦尔山)的区域。现在,麦哲伦探测器开始对金星第三轮测绘,描绘金星立体图像, The Magellan Venus probe, which has just ruled out technical problems, is in short supply. On January 4, the transmitter of Transmitter Probe A failed, now using a B transmitter, but the B-line had a howling noise a year ago. To avoid this howling spectrum, the data rate has to be reduced from 218.8 kbit / s to 115 kbit / s. As such, the data collected by the detector each time Venus is reduced. At the end of January, there are only 15 minutes of orbit per orbit, covering the area of ​​Venus between 17.6 ° and 76 ° north latitude (including Maxwell Hill). Now, the Magellan probe began the third round of mapping of Venus, depicting the three-dimensional image of Venus,
