LARGE NUMBERS OF Americans harshly criticized China’s re-usable booster rocket on social media, saying that the US had already achieved similar feats. They are missing the point. The world took such an interest in China’s achievement not because they claimed to be first--they did not--but because a nation from a poor part of the world successfully did what the world’s wealthiest country had done. Remember, China had the same GDP as India as recently as 1986. It’s not specific achievements, but the speed and velocity of China’s rise that is terrifying the US political-media establishment. And that’s why the US is heavily arming Japan, Taiwan, Australia and a dozen other places to stand by to attack China. . COMPARE PROGRESS The missing context of the reports is this: The US, European nations, and New Zealand are ALL actively working on creating reusable rockets of one kind or another. For an Asian nation to zoom to second place is notable. What the Chinese did this week was to fire a rocket into space and successfully land an orbital booster at sea, for reuse. In achieving this, it can be said that China’s Long March 10B rocket is following in the footsteps of the US. Other rockets which have done this are Falcon 9 in 2015 (by SpaceX, helmed by Elon Musk) and New Glenn in 2025 (by Blue Origin, a Jeff Bezos project). . AHEAD OF EUROPE Yet the Chinese did not demonstrate a copy of those systems, but a unique set-up of their own, with the rocket guided down into a floating landing pad while firing retro-boosters. By achieving this feat, the Chinese have overtaken other rich countries, confirming the velocity of China’s rise. Europe’s Ariane Group has been working with the European Space Agency on a reusable rocket stage called Themis. A New Zealand-US project called Rocket Lab has fired boosters, and then parachuted them into the ocean, so parts can be reused on later launches. China has apparently overtaken both projects. . NEXT: SCI-FI ROCKETS It is worth noting that the Chinese are testing multiple systems—so they are also deploying systems where a rocket flies straight up and then returns to earth, intact, to land upright, in the style which has been seen for a half a century in sci-fi movies. Active Chinese companies in this area include LandSpace, Space Epoch, Deep Blue Aerospace and Galactic Energy. So China can say to its American critics: “Yes, you were first. But we’re happy to be making remarkable progress in this area.” Yet the elite in the US will think differently. Their attitude is more likely to be something like this: “Hey, we may be number one now, but at the rate they are going, we’re gonna be eating their dust. How can we Tonya them?” .
