中国的space X 火箭克隆来了

The Hyperbola-2 methane-liquid oxygen reusable verification stage rose to a height of 178 meters during its 51-second flight. It performed a powered descent and soft landing, supported by four landing legs. The 3.35-meter-diameter, 17m-long test stage is powered by a variable thrust Focus-1 engine.

降落很稳，火箭很大，不清楚载荷

好象现在的高科技都没什么门槛啊，大家都建立不起护城河，以后就真是存量博弈阶段了。我估计就这个，你给欧洲或者俄罗斯一些时间和资金，他们都能搞出来。

主要看谁做得更便宜，并且从市场赚钱补贴未来发展。
如果谁像前苏联那样靠政府砸钱一直搞，最终自己玩砸了

神舟飞船返回舱的 1200 平方米主降落伞是 “环帆伞”，不会出现连锁破坏的情况 ( 在非极端情况下即便有局部破损也不会持续扩散 )，并且设计时就考虑到了即便局部破损也能够保证减速效果。

返回舱的另一端有备份伞。神舟飞船返回舱在打开主伞后的降落过程中，一旦下降速度超过设计值，就会弹出备份伞。

破洞以前几次都发生过，设计考虑了。

其他国家只有海上降落，更容易，只有中国搞了陆地降落
