准备好 两年后我们太空旅游

Core Viewpoint - The development of commercial space tourism in China is advancing, with the first batch of ordinary tourists expected to experience space travel by 2028 through the "Chuan Yue" spacecraft, which has begun ticket pre-sales [1] Group 1: Space Tourism Forms - Space tourism currently includes three main forms: suborbital, orbital, and deep space tourism [1] - Suborbital tourism allows passengers to experience weightlessness and view the Earth from about 100 kilometers above, with companies like Virgin Galactic and Blue Origin leading in this area [2] - Orbital tourism involves longer stays in low Earth orbit, with SpaceX conducting missions that include commercial spacewalks [2][3] Group 2: Technical Challenges - Key technical challenges for space tourism include reliable launch systems, safety escape mechanisms, life support systems, and reusability of spacecraft [4] - Successful implementation of these technologies is crucial for the planned 2028 manned flights by domestic companies [5] - Internationally, companies like Virgin Galactic and Blue Origin have transitioned from unmanned to manned flights in 3 to 5 years, but uncertainties remain [4] Group 3: Domestic Developments - "Chuan Yue" has completed the overall scheme verification for a reusable suborbital spacecraft and is set to conduct critical technology validations by 2026 [5] - Other domestic companies, such as Ziwei Technology and Zhongke Aerospace, are also making progress in suborbital flight tests and technology verification [6] Group 4: Requirements for Participation - Participants in suborbital flights need to meet certain health criteria, including the ability to withstand 3 to 4 Gs of overload and short-term weightlessness [7] - The cost of space tourism remains high, with ticket prices starting at 3 million RMB for "Chuan Yue" and exceeding 50 million USD for orbital flights [7] Group 5: Future Price Predictions - The price of space tourism is expected to decrease over the next 20 years, potentially reaching 50,000 to 100,000 RMB as the industry matures and scales [8]
