CAPE CANAVERAL, Fla. — SpaceX launched four astronauts into orbit Friday using a recycled rocket and capsule, the third crew flight in less than a year for Elon Musk’s rapidly expanding company.

The astronauts from the U.S., Japan and France should reach the International Space Station early Saturday morning, following a 23-hour ride in the same Dragon capsule used by SpaceX’s debut crew last May. They’ll spend six months at the orbiting lab.

It was the first time SpaceX reused a capsule and rocket to launch astronauts for NASA, after years of proving the capability on station supply runs. The rocket was used last November on the company’s second astronaut flight.

Embracing the trend, spacecraft commander Shane Kimbrough and his crew weeks ago wrote their initials in the rocket’s soot, hoping to start a tradition.

“If you have rapid and complete reusability, then that is the gateway to the heavens. That’s what we’re trying to get done, and the support of NASA makes a huge difference,” Musk said after the launch.

Just a week ago, NASA awarded SpaceX a nearly $3 billion contract to provide the lunar lander that will deliver astronauts to the surface of the moon — Musk’s Starship, intended to be fully reusable to attain his ultimate prize of carrying astronauts to Mars and building a city there.

Flying in a recycled capsule Friday provided a bit of deja vu for NASA astronaut Megan McArthur. She launched in the same seat in the same capsule as her husband, Bob Behnken, did during SpaceX’s first crew flight. This time, it was Behnken and their 7-year-old son waving goodbye. McArthur blew kisses and offered virtual hugs.

Also flying SpaceX on Friday: Japan’s Akihiko Hoshide and France’s Thomas Pesquet, the first European to launch in a commercial crew capsule.

It was a stunning scene: The launch plume glowed against the dark sky, reflecting the sunlight at high altitude.

Despite the early hour, spectators lined surrounding roads to watch the Falcon take flight an hour before sunrise. Liftoff was delayed a day to take advantage of better weather along the East Coast in case of a launch abort and emergency splashdown.

“You’re seeing a piece of history happening here,” said Lance Bryan, visiting from Burnsville, Minnesota. “It’s, in this case, good history versus some other things that can happen that have been in our backyard practically.”

Hours after liftoff, SpaceX was notified of a piece of space junk that might come dangerously close to the capsule. So flight controllers ordered the astronauts to put on their spacesuits and lower their visors just in case. There was no danger, and the unidentified debris turned out to be farther than initially thought, passing about 28 miles (45 kilometers) from the vehicle.

“We don’t know what the object was or how big it was, but it did not come close to Dragon,” said NASA spokesman Rob Navias.

A masked Musk met briefly with the astronauts at NASA’s Kennedy Space Center before they boarded white gull-winged Teslas from his electric car company. The astronauts’ spouses and children huddled around the cars for one last “love you” before the caravan pulled away and headed to the pad in the predawn darkness.

“From now on, I’ll see you on a screen!” tweeted Pesquet’s partner, Anne Mottet.

Visibly weary, Musk later said he doesn’t sleep the night before a crew launch and this one was no exception.

“It gets a little bit easier, but still pretty intense, I have to say,” said Musk, who started his space company in 2002.

NASA limited the number of launch guests because of COVID-19, but passengers for SpaceX’s first privately purchased flight made the cut. Tech billionaire Jared Isaacman, who’s bought a three-day flight, watched the Falcon soar with the three people who will accompany him. Their capsule is still at the space station and due back on Earth with four astronauts next Wednesday. It will be refurbished in time for a September liftoff. Another crew flight for NASA will follow in October.

For Friday’s automated flight, SpaceX replaced some valves and thermal shielding, and installed new parachutes on the capsule, named Endeavour after NASA’s retired space shuttle. Otherwise, the spacecraft is the same vehicle that flew before.
