The Soyuz is a capsule, not a booster. The Russians do have some big boosters, although nothing in Saturn V class, not that works that is.
I love Star Trek too, but we ain't there yet.
And if you and Lamar Smith (Rep. Texas) get your way, we never will be, now will we?
The only way something "disposable" makes any sense at all is if it leaves the booster on the ground. Say using a great big ass laser for example.
