The four Artemis astronauts have fired up their spacecraft’s engine break away from Earth’s orbit and zoomed towards the moon, a milestone that commits Nasa to the first crewed lunar flyby in more than half a century.

The Orion capsule engine blasted on Thursday the astronauts on their trajectory towards the moon, which they now will loop as part of the 10-day Artemis 2 mission.
The burn lasting just under six minutes propelled them on their three-day voyage towards Earth’s natural satellite.“Looks like a good burn, we’re confirming,” mission control in Houston said.“The crew is feeling pretty good up here on our way to the moon,” said astronaut Jeremy Hansen. “Humanity has once again shown what we are capable of.”
The burn came one day after the enormous orange and white Space Launch System (SLS) rocket carrying the Orion capsule blasted off flawlessly from Kennedy Space Center in Florida for the long-anticipated journey around the moon.Now the astronauts are moonbound, there’s no turning back: they are on a “free return” trajectory, which uses the moon’s gravity to slingshot around it before heading back towards Earth without propulsion.
In the event something goes wrong, the astronauts wear suits that also serve as “survival systems” – in the unlikely case of a cabin depressurisation 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 Christina Koch, and Hansen, a Canadian – 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.
They began the second day of their mission by playing Green Light by John Legend and Andre 3000, Nasa said – a reference to the go signal they would soon get to fire up the engine and move towards the moon.
They also had their first workouts on the spacecraft’s “flywheel exercise device” – each astronaut will carve out 30 minutes a day for fitness to minimise the muscle and bone loss that happens without gravity.
The 10-day Artemis 2 mission is aimed at paving the way for a moon landing in 2028.
The mission 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 will set a record by venturing further from Earth than any human before – more than 250,000 miles (402,336km).
It is also the inaugural crewed flight of SLS, Nasa’s new lunar rocket.
SLS is designed to allow the US 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 US lunar investment has frequently been portrayed as an effort to compete with China, which aims to land humans on the moon by 2030.
During a post-launch briefing, Jared Isaacman, the Nasa administrator, said competition was “a great way to mobilise the resources of a nation”.
The Artemis II commander, Reid Wiseman, describing the moment the crew saw Earth as a whole, said: “You can see the entire globe from pole to pole, you can see Africa, Europe, and if you look closely, the northern lights. It was the most spectacular moment and it paused all four of us in our tracks.”
“Competition can be a good thing,” he said. “And we certainly have competition now.”
The Artemis program has come under pressure from Trump, who has pushed its pace with the hope that boots will hit the lunar surface before his second term ends in early 2029.
