The final frontier continues to be a battleground for scary weapons and, once again, its China's advances that are the cause of most of the worry.
The Chinese launched a missile in 2013 that reached 10,000 km above the earth, its highest sub-orbital launch since 1976, which led to fears that the rocket could be used in the future to carry an anti-satellite weapon.
It was enough for the US State Department to call on China to "refrain from destabilising actions".
