Core Viewpoint - The establishment of China's first commercial spaceflight propulsion system testing platform marks a significant step towards the realization of space tourism, with the launch of the reusable "Lihong" series spacecraft aimed at providing space tourism services by 2028 [1][3]. Group 1: Challenges in Space Tourism - The transition from concept to norm in space tourism faces three major challenges: the development of reusable launch vehicles, ensuring life support systems for crew safety, and controlling costs [1][2]. - Developing reusable launch vehicles is crucial for reducing costs, but involves complex challenges in materials science, propulsion technology, and control engineering [1]. - Life support systems must be fail-safe due to extreme conditions in space, and any oversight could lead to catastrophic outcomes [2]. - Cost remains a significant barrier, with current prices for space travel being prohibitively high, such as SpaceX's $55 million for orbital travel and Virgin Galactic's $450,000 for suborbital flights [2]. Group 2: Market Potential and Support - Despite the challenges, the space tourism industry shows promising prospects, with companies like Virgin Galactic and Blue Origin already conducting suborbital flights, and SpaceX sending tourists to the International Space Station [3]. - Increased policy support in China is fostering the growth of commercial rocket and satellite companies, with commercial spaceflight being recognized as a new growth engine in government reports [3][4]. - Predictions suggest that the global space tourism market could reach $300 billion by 2030, with China potentially accounting for over 30% of this market [4]. Group 3: Future Outlook - The successful realization of space tourism requires continuous technological optimization, significant cost reductions, and the establishment of regulatory standards [4]. - The industry is expected to evolve from being an exclusive experience for the wealthy to a more accessible market, as ongoing developments in technology and infrastructure progress [4].
