The Power of “Her” Successful flowers— people admire only their brilliance in bloom. Yet in the beginning, their tender buds were soaked in the tears of struggle and nourished by the rain of sacrifice. She is right beside us. She does not have to grow into a rose. If she wishes, she may be a daisy, a jasmine, a sunflower, or a nameless little flower, one among millions. Today is International Women’s Day. May every “her” bloom like a flower, radiant and full of grace.

UPDATE | LandSpace’s New High-Thrust Engine Completes Full-System Long-Duration Test At the beginning of the year of the horse, LandSpace has fully resumed its R&D, production, and testing activities. Recently, the company’s independently developed BF (蓝焱) 220-ton-class LOX–methane Full-Flow Staged Combustion (FFSC) engine successfully completed a long-duration full-system hot-fire test, marking continued progress in the development of high-thrust, high-performance liquid rocket engines. The BF engine is designed using the advanced FFSC cycle, combined with a highly integrated architecture and high chamber pressure design. It features two preburners: a fuel-rich preburner driving the fuel pump and an oxygen-rich preburner driving the oxidizer pump. The two gas streams are then routed into the main combustion chamber, where they burn completely to ensure optimal performance. Compared with conventional engine cycles, the FFSC cycle offers higher propellant utilization efficiency, greater thrust-to-weight ratio, and longer service life. However, it also introduces significant engineering challenges, including high system coupling, structural complexity, multiple vibration sources, elevated internal pressures, and intense thermal loads. Development of the BF engine has progressed rapidly. Since its first full-system hot-fire test in May 2025, it has accomplished more than 100 full-system ignition tests. The successful completion of this latest long-duration test demonstrates steady progress in key technology development and confirms LandSpace’s capability to carry out the complete development cycle of FFSC engines, supported by an agile testing and iteration approach. These advances further improve the engine’s technical maturity and lay a solid foundation for future development. The BF engine will serve as a critical propulsion building block for the next generation of large to heavy-lift launch vehicles, supporting the development of high-efficiency and reusable heavy-lift propulsion systems.

Beginning of Spring (立春 · 1st Solar Term) The East Wind Thaws the Earth A new spring begins. A new cycle unfolds. A new year quietly takes shape. The breath of heaven and earth shifts, and sunlight grows suddenly clearer, brighter. Where the east wind passes, even the firmest ice begins to yield. Frozen ground loosens, layer by layer— not in noise, but in certainty. The east wind moves on, and with it, the earth awakens. Spring has arrived!

Update on ZhuQue-3 (ZQ-3) Y1 Second-Stage Re-entry Based on the information currently available, the second stage of the ZhuQue-3 (ZQ-3) Y1 launch vehicle re-entered the atmosphere over the South Pacific Ocean at approximately 20:39 (UTC+8) on January 30. The stage ablated and disintegrated as expected. We will continue to closely monitor issues related to spacecraft re-entry and space debris mitigation, actively uphold the principles of responsible space activities, and maintain ongoing communication with relevant authorities.

Greater Cold (大寒 · 24th Solar Term) Winter Has an End, Spring Has a Signal At Greater Cold, deep winter makes its final pause, and the annual cycle of the twenty-four solar terms comes to a close. Over the past year, we measured time by missions and milestones, advancing our engineering work with discipline and purpose. Different technical paths converged on one shared direction: higher launch cadence, greater reliability, and lower cost on access to space. Beneath the stillness of winter, momentum continues to build. Reusable Rocket is not a display demo for “Concept Shows”, but an essential answer as satellite constellations move toward large-scale deployment. After the Greater Cold has run its course, spring never breaks its promise. We move forward with steady steps— honoring the work of this year, and ready for the next.

Lesser Cold (小寒 · 23rd Solar Term) Lesser cold arrives, the hush of the year’s deepest chill. Though winter tightens its hold, spring already lies in wait. All things under heaven gather their strength in silence, preparing for the next awakening. Wild geese turn north, flying homeward; magpies flit and weave, carrying twigs to raise new nests; pheasants call to one another, their songs filled with the warmth of belonging. And among us, in our world, countless journeys are being quietly packed — returning roads lined with memory, longing, and warmth. Thus, in the coldest season of all, time itself becomes a passage — leading toward warmth, hope, and reunion. Beyond the depths of winter, gentle spring is already drawing near.

2026 Has Arrived Fireworks rise toward the stars, May every wish come true. 烟花向星辰 所念皆如愿

Winter Solstice (冬至 · 22nd Solar Term) A Warm Sun Within On the Winter Solstice, the Sun shines directly over the Tropic of Capricorn, and the Northern Hemisphere enters the longest night of the year— a natural rhythm of celestial motion. In Chinese tradition, the Winter Solstice is as significant as the New Year. From this day onward, our ancestors began to count the nine, marking the passage from winter toward spring, recording the subtle changes of nature along the way. To count the nine is to count hope, to hold an expectation of spring within the cold. It is our way of understanding nature, and our response to its laws. Though the night is deep, the Sun has already begun its return. Though the road is hard, the direction has been proven. Unhurried, step by step, we count our way toward warmth. With a warm sun in our hearts, we set out once again.

Greater Snow (大雪 · 21st Solar Term) Seeking the Sky on Winter Footsteps ❄️ As Major Snow arrives, nature draws inward and the mountains turn white. In this quiet winter season, the ZhuQue-3 has completed a remarkable and significance maiden flight. 🐦‍🔥 Its large-scale architecture, stainless-steel structure, and nine-engine liquid oxygen–methane propulsion system, a suite of cutting-edge, world-class technologies— were all successfully validated in this flight. This marks China’s first attempt at recovering the first stage of an orbital-class launch vehicle, yielding exceptionally valuable real-flight data. Like a spark glowing through falling snow, it illuminates the future of reusable rockets in China. Snow falls and the hearth glows warm; the world grows still. Yet the ZhuQue rises, leaving footprints in the snow as it asks the sky for an answer.
