It would no longer be "life as we know it" if a space war destroyed the satellites that the world now relies on, space commanders have warned, and China and Russia have demonstrated that they're capable of doing just that. Lt Gen Nina Armagno, staff director of the US Space Force, said Russia's destruction of one of their own satellites last year was a "stunning display". "We're interpreting that ... as a message and demonstration of capability," she said. She said China was openly documenting and describing its demonstrations of power in space. Asked what the end game could be, she said, "Life as we know it would no longer be as we know it." Attacks on satellites can take out GPS systems, banking systems, power grids, first responders' communications, and impact on military operations. "I don't want to be dramatic," Armagno said. "What does war in space look like? We probably won't see it with our naked eye but we will definitely feel the consequences from the moment it begins." She also described China's 2007 destruction of one of its own satellites as shocking, irresponsible and intentional. There are two ways attacks on satellites could take out communication networks. A direct attack " through anti-satellite missiles, grappling arms, or hacking or jamming a satellite " is one. The other is the debris created by a destroyed satellite. Armagno said the US was still tracking 600 pieces of debris from China's 2007 "demonstration".
