China Moving At 'Breathtaking Speed' In Final Frontier, Space Force Says

Indeed, China demonstrated direct-ascent ASAT, or anti-satellite, weapon technology back in January 2007, when it destroyed one of its defunct weather satellites with a missile. That test was widely decried as irresponsible, for it generated thousands of pieces of debris, many of which are still cluttering up Earth orbit. Such activities show that China is now treating space as a war-fighting domain, Whiting said. And so, he added, is Russia, which has also conducted ASAT tests recently, including a destructive one in November 2021. Russia has also been aggressively building out its orbital architecture; since 2018, the nation has more than doubled its total number of active satellites, according to Whiting. The U.S. government has taken notice of these trends. 'We are at a pivotal moment in history,' Troy Meink, principal deputy director of the National Reconnaissance Office, which builds and operates the United States' fleet of spy satellites, said during a different talk on Tuesday here at the symposium. 'For the first time in decades, U.S. leadership in space and space technology is being challenged,' Meink added. 'Our competitors are actively seeking ways to threaten our capabilities, and we see this every day.' The U.S. must act if it wishes to beat back this challenge, Meink and Whiting stressed; it cannot rely on the inertia of past success to do the job. For example, Meink highlighted the need to innovate with the nation's reconnaissance satellites, to make them more numerous, more agile and more resilient. U.S. Under Secretary of Defense for Research and Engineering Heidi Shyu also emphasized the importance of increasing resilience, a goal that she said could be achieved by diversifying the nation's space capabilities. 'We must assess ways to incorporate radiation-hardened electronics, novel orbits, varied communication pathways, advancements in propulsion technologies and increased cooperation with our allies,' Shyu said in another talk on Tuesday at the symposium.
