史上第一颗围绕水星运行的航天器4月30日以硬着陆的方式结束了4年探索之旅。据美联社报道,美国航天局的“信使”号探测器按计划脱离轨道,以每小时14081公里的速度撞上这颗距离太阳最近的行星,在水星表面留下一个直径约16米的大坑。据悉,水星体积不大,而温度极高。2011年,“信使”号成为首个围绕水星运行的航天器。它围绕这颗最接近太阳系中心的行星转了4105圈,拍摄了27.7万张照片。
In the history of the first spacecraft to run around Mercury on April 30 to a hard landing ended the 4-year journey of exploration. According to the Associated Press, NASA’s “Courier” probe was orbiting as planned and hit the planet closest to the sun at a speed of 14,081 kilometers per hour, leaving a surface of Mercury with a diameter of about 16 meters Big pit. It is reported that Mercury is small, but the temperature is high. In 2011, Messenger became the first spacecraft to run around Mercury. It turned 4105 laps around the planet closest to the center of the solar system, photographing 277,000 photographs.
