SpaceX Inspiration4 mission splashdown ends historic trip around the Earth – CNET

Best three-day “weekend” ever? That may be the question SpaceX’s four civilian astronauts are putting to themselves after successfully returning to Earth on Saturday. The crew of the historic Inspiration4 mission splashed down off the Florida coast at about 7 p.m. local time, after having orbited the globe almost 50 times since Thursday. The astronauts safely exited the spacecraft about an hour after splashdown, following a recovery at sea.

“That was a heck of a ride for us,” mission commander Jared Isaacman tweeted after splashdown. “Congratulations @Inspiration4x!!!” SpaceX CEO Elon Musk said, also via Twitter.

It was the first time a crew composed of private citizens had been launched into orbit, without any professional astronauts aboard. The mission took the crew members much farther out than either Virgin Galactic’s Richard Branson or Blue Origin’s (and Amazon’s) Jeff Bezos traveled on their recent jaunts above the planet. And the Inspiration4 trip helps solidify the notion of sending everyday people into space, for tourism, futuristic international travel and perhaps even colonization of the cosmos.

The mission was bankrolled by Isaacman, a former pilot and the billionaire founder of a payment processing company, who offered up the other three seats to members of the general public: physician assistant Hayley Arceneaux, data engineer Christopher Sembroski and community college professor Sian Proctor (who’s now also the first Black woman to pilot a spacecraft). 

That’s not the only historic first. Arceneaux becomes the youngest American in space at 29 and the first to fly in space with a prosthetic. And the mission will likely remain the farthest human spaceflight since the Space Shuttle missions of the early 2000s. Reaching an altitude of around 360 miles, it exceeds the missions designed to service NASA’s Hubble Telescope, which saw astronauts fly to around 370 miles above the Earth. A future SpaceX mission, aboard the still-in-development Starship, plans to take humans farther than ever before — by flying them around the moon in 2023

The crew spent its time orbiting the Earth every 90 minutes (about 100 miles farther out than the International Space Station); checking out the view of our planet from a specially installed glass cupola on SpaceX’s Dragon capsule; conducting various science experiments; and occasionally taking breaks to play with a plushie pup (also known as the mission’s “zero gravity indicator”). Physiological information about the crew was collected to assess changes in behavior and cognition, including data on heart rate, blood oxygen saturation and how well the team members slept.

The mission was also billed as a fundraiser for St. Jude’s Children’s Research Hospital, where Arceneaux works and where she was a cancer patient as a child.

On Saturday evening, Musk announced he would be donating $50 million to the donation drive, helping it surpass the $200 million mark set by the crew. Isaacman is contributing $100 million. 

The successful mission is another feather in the cap of Musk and his company SpaceX, which has already shuttled astronauts to the International Space Station as part of NASA’s Commercial Crew Program. That initiative sees the space agency working with private companies to achieve NASA’s stated goal of “safe, reliable and cost-effective access to and from the International Space Station and low-Earth orbit.”

In June, SpaceX signed a deal to send space tourists to the ISS starting next year (at a reported $55 million price tag per seat). And in April, NASA announced that it had selected SpaceX to provide the human landing system for the space agency’s Artemis program. Artemis calls for putting the first woman and next man on the moon sometime soon — and eventually setting up sustainable exploration there. Knowledge gained from Artemis will be put to use in getting ready to send astronauts to Mars.
