Elon Musk's rocky year in China is ending on another sour note. The tech billionaire's SpaceX satellites are catching heat in China after Beijing complained that two satellites launched by the American aerospace manufacturer endangered Chinese astronauts. The topic also attracted some 90 million views on Weibo, a Twitter-like social media service in China. Users criticized the "US Starlink satellites." One person decried the network as a "rogue project" and a "kind of monopoly in the space race."
