Russia working on a space nuclear weapon that worries the White House and Congress. Although the weapon is not yet active, it could endanger the vital network of satellites that allow everything from GPS navigation to military and international espionage work.
White House officials admitted that the issue is “serious,” but that there are ways to “contain” the threat without triggering mass panic. Russia responded Thursday, rejecting the U.S. warnings, which it called a “trick” and “malicious fabrication.”
