The crew got a warning message as they went past the 'point of no return' on their trip to the Moon.

Four astronauts have been in space for three days on the Orion spacecraft. They will travel about 252,799 miles from Earth, the farthest humans have gone.

A radar station in Cornwall helps track the flight, the first manned trip around the Moon in over 50 years.

The Orion spacecraft launched from Florida this week.

The spacecraft is moving towards the Moon with an engine burn. But the crew got an emergency alert about a cabin leak just 20 minutes later.

Jeremy Hansen said they got a 'cabin leak suspected' warning, which was serious. They had to think about what to do to get home safely.

NASA shared one of the first images taken by the crew on their trip to the Moon.

A cabin leak could be deadly, but checks showed it was just a glitch. The ship's toilet issue was also fixed.

NASA shared stunning images of Earth taken by the crew. The photos show the curved Earth and the whole globe with clouds.

The Artemis II mission will take humans further into space than ever.

NASA's Lakiesha Hawkins said the crew was in good spirits. She liked the image of Earth taken by the crew.

The crew is over 110,000 miles from Earth and will circle the Moon on Monday. They will go 4,000 miles beyond the far side of the Moon.

The astronauts will lose contact with Earth for 40 minutes on the Moon's far side. The mission tests technologies for trips to Mars.

NASA plans to return a crew to the Moon by 2028. China also plans to send astronauts to the Moon around 2030.
