封面新闻记者 吴雨佳 近日，搜狐创始人、董事局主席兼首席执行官、物理学博士张朝阳以"我们所居住的太阳系"为主题开启他的第三场跨年演讲。 潮汐力是怎么产生的呢？张朝阳通过对引力势的球谐展开，阐明了卫星在公转时会受到一种特殊力量的拉扯，这就是潮汐力的起源。张朝阳还提到，在极 端情况下，潮汐力甚至能毁灭星球。当小质量星球过分靠近大质量星体时，巨大的拉扯力足以将其撕成碎片，这也是土星环的一个可能成因。 更有趣的是，在地月系统中，由于地球自转偏快导致潮汐形变稍有延迟，地球隆起的方向并不完全对准月球，这就导致月球持续受到一个力矩作用，其轨 道半径以每年3.8厘米的速度扩张。反之，月球受地球潮汐作用产生的形变滞后，也会通过力矩作用减缓自身自转速度，最终形成与公转同步的潮汐锁定 状态，这也是人类始终只能观测到月球一面的原因。 我们的太阳系有太多奥秘等待探索，张朝阳带观众领略了飞出地球的三个站点。 第一站是拉格朗日点。所谓拉格朗日点，就是由质量悬殊的两个天体组成的公转系统中的5个受力平衡点。这些地方具有独特的力学稳定性，因而科学家 们在这些地方部署了大量探测器，例如韦布望远镜就部署在了日地系统L2点。太阳与木星系统中的L4和L ...

China is currently in a phase similar to SpaceX's network-building period from 2018 to 2020. As the G60 and GW networks enter a dense launch phase, satellite manufacturing is transitioning from custom lab designs to mass production akin to automotive assembly lines. The most certain alpha returns in the industry will come from high-value, high-barrier core satellite components and payloads [2]. Summary by Sections 1. SpaceX Overview - SpaceX is not a traditional aerospace manufacturer but a monopolist in space logistics and infrastructure, applying first principles to disrupt conventional beliefs about rocket costs and single-use designs. It has created a self-reinforcing business loop by leveraging the unmatched launch cost advantages of Falcon 9 to build the largest space communications network, Starlink, and using the cash flow generated to fund ambitious projects like Starship [4]. 2. Competitive Advantages - **Cost Barriers**: SpaceX's reusability model has drastically reduced launch costs, with marginal costs dropping to nearly $15 million per launch, achieving gross margins of around 68% after five reuse cycles. This cost structure provides SpaceX with pricing power against traditional aerospace giants [4]. - **Manufacturing Barriers**: Over 80% of SpaceX's components are self-developed, allowing for rapid iteration and cost control through vertical integration. This strategy has transformed rocket manufacturing from a craft-based approach to an industrialized process [4]. - **Customer Barriers**: SpaceX has established a strategic symbiosis with the U.S. government, which has become a significant source of funding for its core R&D through long-term contracts, ensuring a reliable and cost-effective access to space [4]. 3. Growth Curves - SpaceX's value proposition should not be compared to traditional defense contractors but viewed as a combination of three distinct business life cycles: 1. The launch business as a cash cow with high market share and profitability. 2. The exponential growth of Starlink, transitioning from B2B to B2C services, characterized by recurring revenue similar to SaaS models. 3. The disruptive potential of Starship, which could unlock trillion-dollar markets in space tourism, intercontinental transport, and deep-space resource extraction [4]. 4. Financial Trajectory - SpaceX has seen its valuation soar from approximately $27 million at inception to nearly $200 billion, reflecting a growth of nearly 7400 times over two decades. The financing history shows a clear evolution from focusing on cheaper rockets to expanding into satellite internet and ambitious space exploration projects [29][30]. 5. Product Ecosystem - SpaceX's business model is built on a self-reinforcing loop, utilizing its launch market dominance to deploy Starlink satellites at internal marginal costs, thereby increasing competitive pressure on rivals. The combination of stable cash flow from launch services and the growing SaaS revenue from Starlink supports the overarching goal of funding Starship development [31][32].
