The Polaris Dawn mission, which aims to carry out the first private spacewalk, has been postponed for the second day in a row. The first postponement was due to a leak and the second due to unfavorable weather conditions, according to an announcement published late Tuesday night (27).
The launch is initially scheduled for early Tuesday at NASA's Kennedy Space Center in Florida, USA. A second attempt was scheduled for Wednesday morning.
Due to the forecast of unfavorable weather conditions in the landing areas, [Crew] Dragon off the coast of Florida, SpaceX is hanging up the launch windows for the Falcon 9 Polaris Dawn mission on Wednesday, August 28, and Thursday, August 29. “SpaceX teams will continue to monitor the weather for favorable conditions for launch and return.”
The Crew Dragon, which will take astronauts into orbit around Earth, has already been used to transport members of Crew-1 to the International Space Station (ISS) and on the Inspiration4 mission, which has an all-civilian crew.
The company claims it will be the fourth flight of the Falcon 9 first stage, which will return and land on Earth.
American billionaire Jared Isaac, founder of digital payments company Shift4, is the project leader and was also in charge of the 2021 Inspiration4 mission. Isaacman will be the mission leader, as he was on the previous mission.
In addition to him, the Crew Dragon capsule will include: Scott Poteet, vice president of strategy at Shift4; and Sarah Gillis and Anna Menon, engineers at SpaceX.
The mission is intended to place itself in an elliptical orbit with an apogee of 1,400 kilometers and a perigee (closest point to the surface) of 190 kilometers. If that happens, the mission will be the furthest from Earth's orbit, beating the American Gemini 11 spacecraft, from September 1966, which reached an apogee of 1,369 kilometers.
But the most daring aspect of the mission is the spacewalk, which should take place on the third day of the flight, at an altitude of about 700 kilometers.
Those selected for the outing are Isaacman and Gillis, who will remain attached to the capsule by umbilical cords. Poteet and Menon will remain on board for technical support.
Although only half of the team will make the trip, everyone will be exposed to the void. The entire procedure should take about two hours.
