This Wednesday, at 4 pm (Paris time), William Shatner, who played the famous Captain Kirk in the series "Star Trek", will - really - go into space.
The 90-year-old Canadian will take off from Texas aboard the New Shepard rocket, along with two Americans and an Australian, for Blue Origin's second manned suborbital flight.
He will thus become the oldest person to go into space, dethroning Wally Funk who, at 82, won the title in July during the first commercial flight of the company of Jeff Bezos, then also a passenger.
The flight of the four tourists should take place in the same way as that of the billionaire: about ten minutes in total, of which about four in zero gravity.
The spacecraft will fly just above the Karman Line, which marks the border of space at an altitude of 100 km according to the international convention.
Blue Origin is bringing the launch live on its YouTube channel.
The flight was originally scheduled for Tuesday, but was postponed for weather reasons.
Many more takeoffs are expected to follow in the months and years to come: Jeff Bezos said after his short space trip that the company had sold nearly $ 100 million in tickets to future passengers.
