While only two tickets were offered for sale on Thursday, more will be available the next month as Deep Blue Aerospace, a Chinese space firm, plans to launch passengers into space in 2027.
The travelers will reach outer space but not enter orbit because the rocket will take them on a suborbital excursion.
Each ticket in the first round cost 1.5 million yuan (£162,500).
The newest frontier for businesses looking to profit from technology developments that facilitate space travel is space tourism.
The US business Blue Origin and Elon Musk’s SpaceX are both engaged in space travel.
In September, three private astronauts and a billionaire were sent into orbit by SpaceX.
During that voyage, daredevil billionaire Jared Isaacman, 41, became the first person to participate in a private spacewalk, describing the breathtaking vista as “gorgeous” as he stepped out of the spacecraft.
According to the Chinese business Deep Blue Aerospace, it needs reusable rockets to make space tourism feasible. In the first quarter of 2025, it intends to retrieve a carrier rocket from orbit.
