the landing on, samplingfrom , and departuring from the asteriod has to be
totally automatic without any instruction from the Earth due to the long
distance. In another word, the probe had to make its own decision onsite.

China claims to have a working version of NASA’s impossible engine orbiting
the Earth
Scientists in China claim they’ve created a working prototype of the ‘
impossible’ reactionless engine – and they say they’re already testing it
in orbit aboard the Tiangong-2 space laboratory. And will use it in
satellites ‘imminently’.

the orbital laboratory Tiangong-2 (Heavenly Palace 2), which is more than 34

China on Thursday launched an experimental module into space, taking its
first step towards building a space station, state television showed.
Tiangong-1, or "Heavenly Palace", took off from the Gobi desert in China's

BY ONE well-known (if fictitious) criterion, the purpose of a space
programme is to boldly go where no man has gone before. China, however, has
a different plan: to boldly go back where men have already been.
Specifically, with the release on December 29th of an official space-policy
paper, it has said it wants to send people to the moon.

did so in 1972. He was (and is) American. A... 阅读全帖 |

掩盖不住了。更糟糕的是，已经失去控制。重返大气层时可能会掉在人口密集区域。
Tiangong won't be able to burn up in a controlled manner. All we know is it
will burn up at some point in late 2017, but it is impossible to predict
exactly when or where. This means that there is a chance debris from the
falling spacecraft could strike a populated area. |

发帖数: 2565 | 48 看这部片子居然是天朝的同学向我推荐的。
看了还行，是商业片里的难得的成功之作了。
整部电影里最可圈可点的是Goerge Clooney的表演，镇定，风趣，勇敢。是标准的美式
高大全形象，天朝的银幕高大全形象估计会去掉风趣，加上老实。
在美国这么多年过去了，深刻感受了天朝国力的增强，国际社会各大势力的变化，在电
影里能很直接的感受到。电影里的坏人在20年前基本都是苏联的，偶尔有中国和北朝鲜
的打打酱油，现在基本都是穆斯林兄弟干坏事了。地心引力里的破坏者还是老毛子，因
为穆斯林没实力捣这么大的蛋。
要是这部电影是10年前拍的，空间站肯定不是中国的，也不会让女主角拗口地发音“
tiangong”“shen zhou”啥的，空间站估计会是日本的，里面的仪器当然也是日文。
这片子肯定在天朝挣了不少钱。 |

wiki上是这么说到的:Unable to dock the Soyuz with the station, Stone opens
the hatch and uses the force of the explosive decompression plus a fire
extinguisher as a makeshift thruster to cover the distance between the Soyuz
and Tiangong.
看懂的高手解释下是咋个产生explosive decompression?产生的力是继续向前推?如果
是一直往前推接近天宫，为什么要读数或者判断距离操作?我记得当时的镜头是降落伞
当时也在空间打开,不是往前推而是降速了,然后stone彪出来用气筒.所以对降落伞在空
间的阻力觉得不可理解。 |
