SpaceX announced,At about 15:30 on September 15, the Dragon spacecraft carrying out the "Polaris Dawncrew" mission successfully returned to Earth and splashed down in the waters of Florida.The Dragon spacecraft was launched on the 10th, carrying four non-professional astronauts.
The spacecraft's maximum distance from the earth is about 1,400 kilometers, which is the farthest human being has flown from the earth since the Apollo moon landing. Gillis and Menon have also become the women who have flown the farthest in history.
After that, the altitude of the spacecraft dropped to about 700 kilometers, which is still much higher than the International Space Station's altitude of about 400 kilometers.
On the 12th, billionaire Jared Isaacman, the sponsor of the mission, wore a spacesuit developed by SpaceX for extravehicular activities, completing the first commercial spacewalk in human history by non-professional astronauts, and all four astronauts were exposed to the vacuum at the same time.
Previously, 270 astronauts have performed 477 space extravehicular activities.
At the same time, this is also the highest altitude that humans have been exposed to in space since the last Apollo mission in 1972.
