揭秘朝鲜核技术进展的幕后力量:海归科学家
在遭到国际社会一致制裁的情况下,朝鲜核计划怎能进展如此迅速,并完成了首次氢弹
爆炸试验?背后的答案,可能得从近年来留学归国的朝鲜科学家说起。

If you have space-obsessed friends, you might have heard the name "Falcon

Falcon Heavy is a brand new rocket that's set to launch for the first time
ever on February 6, SpaceX announced on Saturday.
The buzz can be attributed to the Falcon Heavy's size: It will be the most
powerful rocket in the world. It's built by SpaceX -- the industry-

大体说来,登月亮的过程是,让火箭推动带有载人舱的卫星突破第一宇宙速度成为地球
的卫星,然后经过变轨进入与月球同步的卫星轨道后,释放一个小型登月卫星舱到月球
。从理论上讲,这个登月卫星舱降落到月球容易,但回来是最空难的。
对天体物理有常识的人都明白,月球质量比地球小很多,引力也只有地球的差不多1/6
,而且还没有大气层的巨大阻力。所以,从月球上发射小型载人太空舱返回月球卫星轨
道的技术难度和操作困难与地球比就小很多很多。 也就是说,只要落到月球表面的载
人舱支架还在,上面的返回火箭没有物理性坡坏,人坐进去后,启动火箭再回到月球轨
道应当没有多大技术问题。
当然了,当登月舱从月球重新返回月球卫星轨道或者直接进入与月球平行的地球轨道后
,与在那里同步运行的飞船对接,或者直接经过变轨而降落到地球不是不可能的事。
