Some of the proposed anti-satellite space weapons (ex. directed-energy weapons) are not technologically feasible with current technology. Researchers are working on concepts but these same researchers have been working for several decades to develop a viable missile defense system without success.

Some of the proposed anti-satellite space weapons (ex. directed-energy weapons) are not technologically feasible with current technology. Researchers are working on concepts but these same researchers have been working for several decades to develop a viable missile defense system without success. Crude ASATs are possible but many of the advanced ASAT ideas being discussed are not feasible within the next 10-15 years.
