President Donald Trump congratulated the Artemis II crew, calling it a "spectacular" trip, and said he looks forward to seeing them at the White House "soon," in a social media post following the successful splashdown.

A TV was wheeled into the roundtable dinner that the president was attending in Charlottesville, Virginia, and he watched the Artemis splashdown, according to a White House official.

The side hatch of the Orion capsule is now open, as four Navy personnel -- one for each astronaut -- enter the capsule to check on the crewmembers.

Recovery personnel, including Navy divers, have pulled up along the Orion capsule to help extract the crewmembers.

The astronauts will stay inside the Orion capsule as it’s powered down and recovery teams move in to help them out and take their first breaths of fresh air on Earth since April 1.

They were initially expected to begin exiting the spacecraft around 9:06 p.m. ET but it's possible that could be pushed back. Christina Koch will exit first, followed by Victor Glover Jr., Jeremy Hansen, and Reid Wiseman last.

After they're helped out of the capsule, the crew will be moved onto a raft. From there, helicopters will lift each astronaut one by one and fly them to the USS John P. Murtha.

NASA has shared additional photos of the far side of the moon taken during the Artemis II crew's historic lunar flyby on Monday.

One image shows a close-up view of Vavilov Crater, an impact crater on the rim of the older and larger Hertzsprung impact basin, none of which can be seen from Earth.

Another image shows the Orientale basin in the center with a black patch of ancient lava that punched through the moon's crust in an eruption billions of years ago. It is located on the western border between the near and far side of the moon and is hard to see from Earth.

A third image captures the lunar surface in sharp detail while a distant Earth hovers in the background.

Also captured by the Artemis II crew is the heavily cratered terrain of the eastern edge of the South Pole-Aitken basin, an impact crater on the far side of the moon.

The basin is seen with the shadowed terminator -- the boundary between lunar day and night -- at the top of the image.
