Lesser Heat (小暑 · 11th Solar Term) All things come to fruition in their season; all engineering stands upon verification. As of the first half of this year, the TianQue series LOX/Methane engines have accumulated over 176,000 seconds of component and full-system test firings, surpassing 1,100 ignitions, with more than 150 engines produced. Milestones matter, but verification matters more. Time has always been a part of engineering. The answers in spaceflight are not found in a single dawn or dusk, but in every second of verification, every step of accumulation.
