THE ORBITAL SPECTATOR: Satellites and Seriousness

Codevilla, Angelo M.

EACTIONS TO CHINA'S JANUARY 11 TEST of a direct ascent anti-satellite weapon have not been commensurate with the prospect that the U.S. military will have to fight the next war without assurance...

...But their relationship with one another is entirely predictable...
...That means that any time anyone launches any satellite into orbit, he can put a bomb on it and program it to end up right next to any other satellite...
...Hence defense must be active: Somethinghastoshootdownwhateverisshotatthem...

...Nowadays, their instruments, fed by satellite data, allow them to hit their targets by shooting just a few rounds or missiles...

...That was a wastefully hard way to do a simple job...
