Four private astronauts returned to Earth on Friday after a groundbreaking four-day mission aboard a SpaceX capsule, marking the company's sixth fully private spaceflight.
The crew, led by Maltese investor Chun Wang, embarked on a unique polar trajectory, orbiting the planet from pole to pole every 40 minutes — a novel orbit the first for human space travel.
Launched from Florida on Monday night, the mission involved conducting 22 research experiments focused on the effects of microgravity on the human body.
The diverse four-person team included Wang's friends and associates: Norwegian film director Jannicke Mikkelsen, German robotics researcher and polar scientist Rabea Rogge, and Australian adventurer Eric Philips.
Their Crew Dragon capsule tightened its orbit around Earth Friday morning and splashed down hours later off the coast of California around noon EDT, before the gumdrop-shaped spacecraft was hoisted out of the water by a SpaceX vessel and scooted under a shaded platform onboard.
As a final experiment, the crew exited Dragon without the delicate assistance from medical and support teams that astronauts usually receive upon returning to Earth.
No stretchers rolled them out of the capsule to demonstrate how well astronauts could walk off a spacecraft on the moon or Mars.
Spaceflight, particularly on missions much longer than the Fram2 flight, is known to reduce bone density and muscle mass, among other bodily effects that have been studied for decades by the National Aeronautics and Space Administration with its astronauts on the International Space Station.
Each crew member on Friday slowly crawled out of Dragon one by one, their flexibility seemingly constrained only by their flight suits, before standing upright with smiles.
"All four framonauts have safely exited Dragon unassisted," SpaceX said, referring to the crew.
SpaceX and its Dragon craft have dominated the nascent market for private orbital spaceflight, an area in which a key source of demand originally came from a small field of wealthy tourists.
Dragon is the world's only privately built capsule routinely flying missions in orbit. Rival Boeing's Starliner capsule has been held up in development.
In recent years, with Dragon flights costing roughly $55 million per seat, the spaceflight market — involving companies such as Axiom Space that contract Crew Dragon missions — has fixated more on astronauts from governments willing to pay the sum mainly for national prestige and bolstering domestic spaceflight experience.
