Re: Hit the US?

according to the rocket equation

What f***ing equation?

Orbital velocity by the station remnant - 8km/s. ~50-70% of orbital velocity by the interceptor - they do not reach full 8km/s. If you are lucky and you manage to match them perfectly head on - 12km/s relative. If not - you are still looking at > 8km/s. How much energy did the rocket expand is irrelevant. What is relevant is what speed did it reach relative to the target.

Let's assume 10kg (it is more) and we get a nice rounded number of 1.44 TeraJoules. One Kiloton is 4.88 Joules. So we are looking a nearly 300 tons of TNT equivalent. Even if it was just hitting at 8km/s you are still looking at > 100 tons equivalent.

There will be NOTHING left from the station if it hits. The "if it hits" is the big if - they do not have a very stellar record.
