Four private astronauts completed the sixth full private space mission aboard a SpaceX spacecraft, returning to Earth after a four-day polar orbital flight. They conducted 22 studies on changes in the human body under microgravity during the mission and successfully exited the spacecraft without external assistance, demonstrating that astronauts can operate effectively on the Moon or Mars. This mission was led by Maltese investor Wang Chun, and the Dragon spacecraft landed off the coast of California at noon Eastern Time. Each member stepped out of the spacecraft energetically, showcasing good flexibility.

Four private astronauts successfully returned to Earth today after flying in a new polar orbit around the globe for about four days aboard a spacecraft from Space Exploration Technologies Corp., completing the company's sixth full private space mission. They exited the spacecraft smoothly without much assistance.

Since launching from Florida, USA on the evening of March 31, the four-member crew, led by an investor from Malta, flew along a unique trajectory that circled the Earth from the North to the South Pole, passing over snow-covered polar regions approximately every forty minutes. During the mission, they completed twenty-two research experiments, primarily focusing on human changes in microgravity conditions.

• Among the crew members are three friends and partners of Wang Chun:
• Norwegian filmmaker Mikkelsen
• German robotics researcher and polar scientist Rog
• Australian adventurer Phillips

This morning, their "Dragon" spacecraft performed a progressively smaller orbital flight around the Earth and landed off the coast of California around noon Eastern Time; subsequently, the spacecraft was lifted from the water by a SpaceX ship and moved under a shelter platform on the ship.

Typically, astronauts are assisted by medical and support teams when returning to Earth, but in the final experiment of this mission, the crew members exited the Dragon on their own without relying on the team, and did not use a stretcher, demonstrating that astronauts can successfully step out of a spacecraft on the Moon or Mars.

For decades, the National Aeronautics and Space Administration (NASA) has sent its own astronauts to conduct research on the effects of spaceflight on the human body, and these types of flights, especially missions longer than this one, are known to result in reduced bone density and muscle mass. Today, all four crew members slowly climbed out of the Dragon one by one; although they were limited by their space suits, they stood tall with smiles on their faces.
