Core Viewpoint - The article discusses the upcoming manned suborbital flight by Beijing Chuanweizhe Manned Space Technology Co., which is set to launch its "Chuanweizhe No. 1" in 2028, with actor Huang Jingyu as one of the suborbital space tourists. This event has sparked public interest and debate about the nature of suborbital flights compared to traditional manned space missions [1][3]. Engineering Perspective - Suborbital flights do not enter orbit and are fundamentally different from orbital missions, requiring distinct engineering systems and objectives. Suborbital flights focus on providing a brief experience of weightlessness rather than achieving long-term orbital capabilities [6][7]. - The engineering goals of suborbital flights are limited to short-term acceleration and deceleration control, structural integrity of the spacecraft, and safety in extreme environments, contrasting with the complex systems required for orbital missions [7][8]. Commercial Viability - The commercial model for suborbital flights is characterized by high ticket prices (approximately 3 million yuan) and a focus on unique, non-replicable experiences, making it more akin to luxury consumption rather than scalable space services [10][11]. - The target demographic for suborbital flights often consists of high-profile individuals whose participation serves more as a marketing tool than a sustainable consumer base, limiting the potential for ongoing demand [11][12]. Market Context - The current state of China's commercial space industry is still developing, focusing on enhancing launch capacity and cost efficiency. High-cost, low-frequency suborbital flights are unlikely to serve as a pathway to more extensive orbital missions [12][15]. - In contrast, the U.S. has a more mature market for both suborbital and orbital flights, supported by private capital and established interfaces between commercial companies and national space agencies [12][14]. Public Engagement - Suborbital commercial flights play a role in making space exploration more accessible to the public, helping to demystify the field and generate interest in space activities [17]. - The significance of these flights may lie more in their ability to engage the public and promote awareness of space exploration rather than in their technical contributions to advancing manned space capabilities [17][18].
