2013年12月2日凌晨1时30分,嫦娥三号月球探测器在西昌卫星中心发射升空。嫦娥三号堪称我国设计制造的最复杂、技术难度最大的航天器之一。实现月球软着陆是此次嫦娥三号的核心任务之一,为了能够成功落月,嫦娥三号使用了先进的大推力变推力发动机,这种发动机能够灵活调节在软着陆下落过程中的推力。此外,测速测距雷达、降落相机、激光测距仪以及先进的导航控制系统,可以保证嫦娥三号安全着陆。当然,它还有自主选择着陆区的能力——识别8°以上的陡坡、识别高度大于0.2米的凸起物。“玉兔号”具备20°爬坡、20厘米越障能力,可耐受
At 1:30 on December 2, 2013, the Chang’e III lunar probe was launched at the Xichang Satellite Center. Chang’e III called China’s design and manufacture of the most complex and one of the most difficult technical spacecraft. To achieve the soft landing of the moon is one of the core tasks of the Chang’e III. In order to be able to successfully launch the moon, Chang’e III has used advanced thrust-changing thrust engines that can flexibly adjust the thrust during a soft landing. In addition, speed ranging radar, landing cameras, laser range finder and advanced navigation control system, Chang’e III can ensure a safe landing. Of course, it also has the ability to choose its own landing zone - identifying steep slopes above 8 ° and recognizing bumps with altitudes greater than 0.2 meters. “Rabbit number ” with 20 ° climbing, 20 cm barrier capability, can be tolerated
