Nasa’s Orion capsule has passed within 80 miles of the moon in the final big stage ahead of its record-breaking lunar orbit.
The close approach occurred as the crew capsule and its three test dummies passed on the far side of the moon during a slingshot manoeuvre.
Because of a half-hour communication blackout, flight controllers in Houston did not know if the critical engine firing went well until the capsule emerged from behind the moon, more than 232,000 miles from Earth.
It is the first time a capsule has visited the moon since Nasa’s Apollo programme 50 years ago, and represented a huge milestone in the $4.1 billion test flight that began last Wednesday.
LIVE NOW: The @NASA_Orion spacecraft is performing its first powered lunar flyby.
Orion will make its closest approach to the lunar surface during the #Artemis I mission - approximately 80 miles – at 7:57am ET (12:57 UTC). https://t.co/rO5HBPx0EcAdvertisement— NASA (@NASA) November 21, 2022
Orion’s flight path took it over the landing sites of Apollo 11, 12 and 14 – humanity’s first three lunar touchdowns.
The moon loomed ever larger in the video beamed back earlier in the morning, as the capsule closed the final few thousand miles since blasting off last Wednesday from Florida’s Kennedy Space Centre, atop the most powerful rocket ever built by Nasa.
“This is one of those days that you’ve been thinking about and talking about for a long, long time,” flight director Zeb Scoville said while awaiting to resume contact.

Orion needed to undertake a slingshot move around the moon in order to pick up enough speed to enter the sweeping, lop-sided lunar orbit.
If all continues to go well, another engine firing will place the capsule in that orbit on Friday.
Next weekend, Orion will shatter Nasa’s distance record for a spacecraft designed for astronauts – nearly 250,000 miles from Earth, set by Apollo 13 in 1970.

And it will keep going, reaching a maximum distance from Earth next Monday at nearly 270,000 miles.
The capsule will spend close to a week in lunar orbit, before heading home. A Pacific splashdown is planned for December 11.
Orion has no lunar lander. A touchdown will not arrive until Nasa astronauts attempt a lunar landing in 2025 with SpaceX’s Starship. Before then, however, astronauts will strap into Orion for a ride around the moon as early as 2024.
Nasa managers were delighted with the progress of the mission. The Space Launch System rocket performed exceedingly well in its debut, they told reporters late last week.
The 322ft rocket caused more damage than expected, however, at the Kennedy Space Centre launch pad.
The force from the 8.8 million lbs of lift-off thrust was so great that it tore off the blast doors off the elevator.
