PLA's Second Artillery Corps to create a mysterious "underground Great Wall"

[GSK]

ya know i was thinking they do have 2.3million man army, with policing work now done by the pap the army can be used for projects like this

Not that simple. You don't want the details of your project like this to go public, so the less people engaged in it the better. And I also believe this kind of project must be done by professionals, skilled workers from the second artillery corp to ensure its top quality.

The danger of putting nukes in space is when the satellite runs out of fuel is loses contact/control with ground station will deviate its trajectory and fall down.

Impossible. There is only enough fuel for a satellite to reach an orbit. Once in that orbit, the centripetal force will keep the satellite in orbit. Remember that there is no atmosphere in space, hence bodies in motion don't lose their velocities applied by a force before reaching a certain orbit.

So how some satellites loose their orbit & fall down on earth ?
