That's No Moon


It is a good start.  We will not be properly in space until we produce what is a spinning top large enough to support one g of centripetal acceleration on hte rim.  This conceptualization is a good start.

Such a system could be natural hundred meters thick on the Rim while widening as we move toward the center hub.  Assuming one hundred levels inside 300 meters with varying levels of acceleration we have around 30,000,000 square meters of active space inside the Rim.  That is a lot and can easily house a half  million residents.

Better, it can all be built using well known materials such as steel.  We can even consider laying in a layer of concrete in the outer skin.

The main load bearing device will always be suspension cables rounding the Hub.  The  only reason to push the envelop in order to reduce weight is false economy.  With our rising rocket tech we can lift into place the necessary steel.  We can also salvage materials as well.  Crushed material serves well as a passive barrier..

China announces plans for 1km-long orbiting spaceship in latest twist in space race with US

A HUGE spaceship up to 1km long could be built by China as the country's space agency is working on a plan for the build.

The National Natural Science Foundation revealed a four year programme is in place to try and work out if they could build such a large ship in orbit.

This would require sending components up to space on rockets and somehow assembling the spaceship in zero gravity conditions.

China's foundation said it was looking at “space equipment for future exploration”.

It has the goal of having a “long-term stay” in orbit.

If the a 1km spaceship was built, that would make it 10 times bigger than the International Space Station.


China's state media has revealed that the plans are complicated.



Components of the craft would need to be as light as possible to make construction viable.

A large spaceship has never been built in orbit before.

China is currently assembling its own space station, just like the ISS, in orbit.


The main section of China’s Tiangong space station was put in orbit back in April.

It's floating 236 miles above the Earth.

China has planned another 11 missions in the next year and a half to finish off building the space station.

The country also landed a rover on Mars this year as it competes with countries like the US in a space race to make discoveries on the Red Planet.
