Are there any way for rockets to fly in space , other then throwing mass
out in one direction and moving in other

Perhaps. But rockets work fine for a lot of purposes.
All that is necessary is sensible system design based
upon technology we already know how to handle.

Unfortunately, organizations and people with the
necessary financial resources seem to eschew this route.
