The quartet of newly minted citizen astronauts comprising the SpaceX Inspiration4 mission safely splashed down in the Atlantic off Florida’s coast on Saturday, completing a three-day flight of the first all-civilian crew ever launched into Earth orbit.

SpaceX’s Crew Dragon capsule, dubbed Resilience, parachuted into the sea around 7 p.m. ET, shortly before sunset, after an automated re-entry descent, SpaceX said during a live webcast shown on its YouTube channel.

The return from orbit followed a plunge through Earth’s atmosphere generating frictional heat that sent temperatures surrounding the outside of the capsule soaring to about 1,900 C. The astronauts’ flight suits are designed to keep them cool if the cabin heats up.

Applause was heard from the SpaceX flight control centre in suburban Los Angeles as the first parachutes were seen deploying, slowing the capsule’s descent to about 24 kilometres per hour before splashdown, and again as the craft hit the water.

Recovery vessels were shown headed toward the water-proof Crew Dragon as it bobbed upright, nose up, in the water.

SpaceX, the private rocketry company founded by Tesla Inc. electric automaker CEO Elon Musk, said it should take about an hour to get the crew out of capsule. A camera shot from inside the cabin showed them sitting calmly strapped into their seats.

SpaceX supplied the spacecraft, launched it from Florida and flew it from the company’s suburban Los Angeles headquarters. The company presented live coverage of the return flight activities by webcast on its YouTube channel.

‘A heck of a ride’

The Inspiration4 team blasted off on Wednesday from the Kennedy Space Center in Cape Canaveral atop one of SpaceX’s two-stage reusable Falcon 9 rockets.

Within three hours the crew capsule had reached a cruising orbital altitude of just over 585 kilometres — higher than the International Space Station or Hubble Space Telescope, and the farthest any human has flown from Earth since NASA’s Apollo moon program ended in 1972.

It also marked the debut flight of Musk’s new space tourism business and a leap ahead of competitors likewise offering rides on rocket ships to well-heeled customers willing to pay a small fortune to experience the exhilaration of spaceflight and earn amateur astronaut wings.

The Inspiration4 team was led by its wealthy benefactor, Jared Isaacman, chief executive of the e-commerce firm Shift4 Payments Inc., who assumed the role of mission “commander.”

“That was a heck of a ride for us,” he radioed from the capsule moments after splashdown. “We’re just getting started.”

He had paid an undisclosed but reportedly enormous sum — put by Time magazine at roughly $200 million US — to fellow billionaire Musk for all four seats aboard the Crew Dragon.

Isaacman was joined by three less affluent crewmates he had selected — geoscientist and former NASA astronaut candidate Sian Proctor, 51, physician’s assistant and childhood bone cancer survivor Hayley Arceneaux, 29, and aerospace data engineer and Air Force veteran Chris Sembroski, 42.

Isaacman conceived of the flight primarily to raise awareness and donations for one of his favourite causes, St. Jude Children’s Research Hospital, a leading pediatric cancer centre in Memphis, Tenn., where Arceneaux was a patient and now works.

The Inspiration4 crew had no part to play in flying the spacecraft, which was operated by ground-based flight teams and onboard guidance systems, even though Isaacman and Proctor are both licensed pilots.

SpaceX already ranked as the most well-established player in the burgeoning constellation of commercial rocket ventures, having launched numerous cargo payloads and astronauts to the space station for NASA.

Two rival operators, Virgin Galactic Holdings Inc and Blue Origin, inaugurated their own astro-tourism services in recent months, with their respective founding executives, billionaires Richard Branson and Amazon.com founder Jeff Bezos, each going along for the ride.

Those suborbital flights, lasting a matter of minutes, were short hops compared with Inspiration4’s three days in orbit.
