China Moving At 'Breathtaking Speed' In Final Frontier, Space Force Says
vendredi 12 avril 2024, 09:00 , par Slashdot
China is rapidly advancing its space capabilities to challenge the United States' dominance in space, as evidenced by its significant increase in on-orbit intelligence and reconnaissance satellites and the development of sophisticated counterspace weapons. Space.com reports: 'Frankly, China is moving at a breathtaking speed. Since 2018, China has more than tripled their on-orbit intelligence, surveillance and reconnaissance satellites,' Gen. Stephen Whiting, commander of U.S. Space Command, said here on Tuesday, during a talk at the 39th Space Symposium. 'And with these systems, they've built a kill web over the Pacific Ocean to find, fix, track and, yes, target United States and allied military capabilities,' he added. And that's not all. China has also 'built a range of counterspace weapons, from reversible jamming all the way up to kinetic hit-to-kill direct-ascent and co-orbital ASATs,' Whiting said.
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.
