嫦娥五号又近一步,四子王旗准备好“接公主”回家!
北京时间12月16日9时15分,嫦娥五号轨道器和返回器组合体上25N发动机工作约8秒钟,顺利完成第二次月地转移轨道修正,组合体上各系统状态良好。
携带着珍贵月壤的嫦娥五号返回器即将结束太空之旅,在内蒙古中部草原的四子王旗着陆场着陆。
据嫦娥五号任务着陆场区指挥部成员介绍,嫦娥五号返回器采用半弹道跳跃式返回方式,也就是俗称的“打水漂”返回方式。这种返回方式控制难度非常大,导致回收区的范围也特别大。为此,需要采取多项措施。
截至目前,着陆场系统已经开展了三次夜间搜索回收专项训练、一次积雪暗夜极寒条件搜索回收演练、一次大范围着陆偏差和三次全系统综合演练,搜索队伍具备空地协同联合搜救能力。
The orbiter-returner combination of China's Chang'e-5 probe successfully carried out its second orbital correction in the moon-Earth transfer orbit on Wednesday, according to the China National Space Administration (CNSA).
The orbital correction was conducted at 9:15 a.m. Beijing Time when two 25N engines of the combination were ignited and worked for about eight seconds.
All the systems on the orbiter-returner combination are in good condition.
The combination carried out the first orbital correction on Monday.
Carrying lunar samples, the returner will separate from the orbiter and go back to Earth alone. The ground team at the landing site in Siziwang Banner of north China's Inner Mongolia has been fully prepared for the historic task after multiple simulation exercises.
Comprising a lander, an ascender, an orbiter and a returner, the Chang'e-5 probe was launched on November 24. Its lander-ascender combination successfully landed on the near side of the moon on December 1, and collected samples from both the lunar surface and beneath.
