The trip is scheduled for 2024 aboard the Spaceship Neptune, a hot air balloon-style craft lifted by hydrogen.
The sale comes just days after the test flight took off on June 18 from the Space Coast Spaceport in Titusville, Florida.
The six hour and 39-minute flight was empty but cameras inside the balloon captured a stunning image of the Earth at sunrise.
But those interested in witnessing the “captivating” scenes must pay a $1,000 deposit to secure their spot.
Jane Poynter and Taber MacCallum, the couple behind SpacePerspective, launched the initiative back in 2019.
The pair are on a mission to take on “the perception of adrenalin-fueled space travel and invite more people than has historically been possible to ride the wave of space history.”
The ballon, which is 700 feet tall, will feature plush seating, 360-degree panoramic windows, WiFi access and other amenities.
There will be a captain on board and passengers won’t require any training before liftoff.
“Our atmosphere stretches for hundreds of miles into space, Spaceship Neptune flies above 99 per cent of it and theperspective of looking down through atmospheric layers, framed by the thin blue line is—according to most astronauts who have experienced it—profoundly life-changing,” the company said.
