Manned mission to Moon fires engines to leave Earth’s orbit for first time in more than 50 years
For the first time since 1972 during Apollo 17, human beings have left Earth orbit
NASA's first manned Moon mission in more than five decades fired its rockets early on Friday to break out of Earth’s orbit.

NASA deputy associate administrator Lori Glaze told a news conference: “Ladies and gentlemen, I am so, so excited to be able to tell you that for the first time since 1972 during Apollo 17, human beings have left Earth orbit.”
She said the engine firing had gone without a hitch.
The four astronauts on the Artemis II mission, which launched from Cape Canaveral in Florida on Wednesday evening, spent the first 25 hours of the flight circling the Earth.
Firing the rockets on the Orion spacecraft – officially called a translunar injection burn – will send them towards the Moon, which they will circle before returning to Earth.

Canadian astronaut Jeremy Hansen said the crew, which also includes Commander Reid Wiseman, pilot Victor Glover and Christina Koch, had been glued to the windows to see the “phenomenal” view.
He said: “Humanity has once again shown what we are capable of, and it’s your hopes for the future that carry us now on this journey around the moon.”
NASA said the firing puts the crew “in a free return trajectory”, enabling them to use the Moon’s gravity for the return journey.
NASA administrator Jared Isaacman said on X: “Nominal translunar injection burn complete. The Artemis II crew is officially on the way to the Moon.
“America is back in the business of sending astronauts to the Moon. This time, farther than ever before.”
“I’m the space plumber, I’m proud to call myself the space plumber.”

NASA said Orion’s main engine, which burned for five minutes and 50 seconds, provides up to 6,000lb of thrust – enough to accelerate a car from 0 to 60 mph in about 2.7 seconds.
There was good news for the astronauts when they were able to fix issues with the toilet, while controllers were also able to raise the cabin temperature.
The Goonhilly Earth Station, near Helston, in Cornwall, is helping to track the flight.
Orion will head around 4,000 miles beyond the moon with a lunar flyby on Monday the next major milestone which will send the crew some 252,000 miles (406,000 kilometres) into space before returning to Earth.
The current record for the furthest spaceflight is about 248,000 miles, held by members of the Apollo 13 lunar mission in 1970, which was hit by technical problems.
While the astronauts will not touch down on the Moon, the Artemis II mission paves the way for a future lunar landing and also lays the foundation to send a crew to Mars.
The mission previously had to be postponed by two months because of hydrogen fuel leaks and clogged helium lines.
NASA is seeking to return a crew to the lunar surface by 2028, before China does in about 2030.
