某旅游平台上架太空游产品 510万元可体验90分钟亚轨道飞行

某旅游平台近日上架了商业太空旅行产品，售价每人510万元起1。这款产品为期6天，包含太空港探秘、模拟舱内训练、全面预演和太空启航等环节1，游客将搭乘维珍银河公司的空射宇宙飞船体验90分钟的次轨道太空飞行1。

亚轨道飞行是在距地表约100公里附近、国际公认的卡门线以下的太空边缘进行的1。相比轨道太空旅游需要达到每秒7.8公里以上的入轨速度1，亚轨道飞行的身体条件要求更为宽松，无需长期培训1，最高点通常在80至100公里附近1。维珍银河公司采用大型载机将火箭飞机带上高空的方式，可以实现重复使用1。这种可重复使用的太空飞行技术代表了商业太空旅游大众化的发展前景。

A Chinese travel platform has introduced a commercial space tourism package priced at 5.1 million yuan per person and up, offering customers a six-day experience that includes a 90-minute suborbital flight aboard Virgin Galactic's air-launch spaceplane 1. The itinerary comprises visits to the spaceport, simulator training, full mission rehearsals, and the spaceflight itself 1.

Suborbital flights operate at the edge of Earth's atmosphere, reaching altitudes around 80 to 100 kilometers, which sits near the internationally recognized Karman line at 100 kilometers that demarcates the boundary between atmosphere and space 1. This differs fundamentally from orbital spaceflight, which requires velocities exceeding 7.8 kilometers per second to maintain stable orbit 1. The suborbital experience is notably more accessible, with significantly less stringent physical requirements and no need for extensive training compared to orbital missions 1.

Virgin Galactic's technology enables repeated use of its aircraft through a carrier plane system, where a large mothership transports the rocket plane to high altitude before release 1. This reusable approach complements other commercial providers like Blue Origin, whose "New Shepard" rocket employs vertical takeoff and landing technology for multi-use missions 1. Such advancements in recoverable spacecraft technology are expected to bring space tourism increasingly within reach of broader consumer markets 1.
