Inspiration4
Best three-day “weekend”? Perhaps that’s the question SpaceX’s four civilian astronauts are asking themselves after their successful return to Earth on Saturday. The crew of the historical mission Inspiration4 splashed off the coast of Florida around 7 p.m. local time after making numerous orbits around the globe since Thursday. The astronauts safely exited the spacecraft about an hour after landing, following a recovery at sea.
“It was a hell of a ride for us”, mission commander Jared Isaacman tweeted after the landing. “Congratulations @ Inspiration4x !!!” SpaceX CEO Elon Musk said, also via Twitter.
It was the first time that a crew composed of individuals had been put into orbit, without any professional astronaut on board. The mission took the crew members much further than the two Richard Branson of Virgin Galactic Where Jeff Bezos of Blue Origin (and Amazon) traveled on their recent trips over the planet. And the Inspiration4 journey helps solidify the idea of sending ordinary people into space, for the tourism, futuristic international travel and maybe even colonization of the cosmos.
The mission was funded by Isaacman, a former pilot and billionaire founder of a payment processing company, which offered the other three seats to the general public: medical assistant Hayley Arceneaux, data engineer Christopher Sembroski and community college professor Sian Proctor (who is now also the first black woman to pilot a spacecraft).

The crew spent their time orbiting Earth every 90 minutes (approximately 100 miles beyond the International Space Station); discover the view of our planet a glass dome specially installed on SpaceX’s Dragon capsule; conduct various scientific experiments; and sometimes take breaks to play with a stuffed puppy (also known as the mission’s “zero gravity indicator”). Physiological information on the crew was collected to assess changes in behavior and cognition, including data on the heart rate, blood oxygen saturation and quality of sleep of the team members.
The mission was also billed as a fundraiser for St. Jude’s Children’s Research Hospital, where Arceneaux works and where she was diagnosed with cancer as a child.
The successful mission is another feather in the cap for Musk and his company SpaceX, which has already astronauts transported to the International Space Station as part of the NASA Commercial Crew Program. The move 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 an agreement to send space tourists to the ISS, from next year. And in April, NASA has announced that it has selected SpaceX provide the human landing system for the space agency’s Artemis program. Artemis calls for sending the first woman and the next man to the moon soon – and possibly set up a sustainable exploration there. The knowledge gained through Artemis will be used to prepare for send astronauts to Mars.
