Four Artemis astronauts were zooming towards the Moon late Thursday after a major engine firing, a milestone that commits NASA to the first crewed lunar flyby in more than half a century.
With enough thrust to accelerate a stationary car to highway driving speed in less than three seconds, the Orion capsule engine blasted the astronauts on their trajectory towards the Moon, which they will now loop as part of the 10-day Artemis 2 mission.
In the moments that followed what the US space agency dubbed a “flawless” firing that lasted just under six minutes, astronaut Jeremy Hansen said that “humanity has once again shown what we are capable of.”
The astronauts said they were “glued to the window” taking pictures, and later passed a floating microphone back and forth as they took questions from US television networks
They said the spacecraft was a little chilly and they were still making it a home, but the crew was all smiles.
“There’s nothing that prepares you for the breathtaking aspect of seeing your home planet both lit up bright as day, and also the Moon glow on it at night with the beautiful beam of the sunset,” said Christina Koch.
Thursday’s nudge came one day after the enormous orange-and-white Space Launch System, SLS, rocket carrying the Orion capsule launched from Kennedy Space Centre in Florida for the long-anticipated journey around the Moon.
The astronauts are now on a “free return” trajectory, which uses the Moon’s gravity to slingshot around it before heading back towards Earth without propulsion.

“From this point forward, the laws of orbital mechanics are going to carry our crew to the Moon, around the far side and back to Earth,” NASA official Lori Glaze said.
The astronauts are wearing suits that also serve as “survival systems” — in the unlikely case of a cabin depressurization or leak, they’ll maintain oxygen, temperature controls and the correct pressure for up to six days.
The astronauts — Americans Reid Wiseman, Victor Glover and Koch, along with Canadian Hansen — spent their first hours in space performing checks and troubleshooting minor problems on the spacecraft that has never carried humans before, including a communications issue and a malfunctioning toilet.
Queried on the toilet situation, Koch said she was “proud to call myself the space plumber.
“I like to say that it is probably the most important piece of equipment on board,” she said. “So, we were all breathing a sigh of relief when it turned out to be just fine.”
Herculean
Crewmembers also had their first workouts of the mission on the spacecraft’s “flywheel exercise device” Each astronaut will carve out 30 minutes a day for fitness, a bid to minimise the muscle and bone loss that happens without gravity.
The 10-day mission is aimed at paving the way for a Moon landing in 2028.
Artemis 2 marks a series of historic accomplishments: sending the first person of colour, the first woman and the first non-American on a lunar mission.
If all proceeds smoothly, the astronauts could also set a record by venturing farther from Earth than any human before.
“There is nothing normal about this,” said Wiseman. “Sending four humans 250,000 miles away is a Herculean effort, and we are now just realising the gravity of that.”
The Artemis 2 mission is part of a longer-term plan to repeatedly return to the Moon, with the goal of establishing a permanent base that will offer a platform for further exploration.
The current era of American lunar investment has frequently been portrayed as an effort to compete with China, which aims to land humans on the Moon by 2030.
Asked about division closer to home and what message they had for Americans, Glover said from his vantage point, “You look amazing. You look beautiful.”
“From up here, you also look like one thing,” he added. “We’re all one people.”
