SpaceX is set to launch its Polaris Dawn mission from the Kennedy Space Centre in Merritt Island, Florida on Tuesday, September 10.
The SpaceX Falcon 9 rocket will carry the Crew Dragon capsule 'Resilience' into orbit, with American billionaire Jared Isaacman and three others set to reach up to 1,400 kilometres above Earth.
It would mark the furthest distance traveled by any crew since NASA's Apollo programme, taking them through parts of the Van Allen radiation belt where they will study the effects of space radiation and spaceflight on the human body.
During the five-day mission, the crew will also attempt the world's first private spacewalk.
The mission has been postponed three times, due to unfavourable weather in the splashdown zone and earlier due to a helium leak.
