The Artemis programme hopes to return human beings to the Moon - more than 50 years after we first set foot there.

"As we leave the Moon… we leave as we came and, God willing, as we shall return, with peace and hope for all mankind. Godspeed the crew of Apollo 17."

These were the words spoken in December 1972 by Commander Eugene "Gene" Cernan, the last astronaut to walk on the Moon, as he prepared to climb the ladder into the lunar module for the flight home.

Cernan and his pilot Harrison Schmitt set several records during three days in the Taurus-Littrow valley: the longest stay on the Moon - 75 hours, the unofficial lunar rover speed record - 11.2 mph (18km/h), and the largest amount of rock-and-dust samples collected - 243.6lb (110.5kg), including some orange soil - small spheres of volcanic glass.

Before leaving the Moon's surface, Cernan wrote his daughter Teresa Dawn Cernan's initials in the lunar dust. They're still there, undisturbed among the footprints and tyre tracks.

Gene Cernan didn't know it would be more than 50 years before humans would make the journey back to the Moon. The next mission to land, scheduled for 2028, will be at a different location - the lunar South Pole.

Vanessa Wyche, director of Houston's Nasa Johnson Space Center, calls the newly announced Artemis III space crew forward to the front of the stage for a final round of applause.

They stand cheerily, shoulder to shoulder, arms wrapped around one another, smiling upon the crowd.

"As you prepare to embark on this next giant leap, know, we stand united, ready to support you at every turn with mission excellence, pushing the boundaries of what's possible for the benefit of all humanity," she says.

And with that, the ceremony has concluded.

We are now hearing recorded messages from members of the US Congress.

Up first is Texas Senator Ted Cruz, chairman off the Senate's Committee on Commerce, Science, and Transportation, who begins by congratulating the just named crew.

"It is a big damn deal," he says. He says at a time of growing competition with China in space, "this mission will strengthen America's leadership, expand our economy, and help secure a lasting American lunar presence."

"When America commits to a mission, we lead and we succeed," he adds.

Representative Brian Babin of the US House Science, Space, and Technology Committee is up next.

"Through your dedication, courage, and service, you will help open a new chapter in humanity's journey beyond Earth," he says. "Please know that you have the support of the American people," he says.

Three astronauts from the Artemis II crew, who flew around the Moon earlier this year, have now taken to the stage to express their congrats.

Reid Wiseman, the commander of Artemis II, says the group wanted say how "fired up" they were for Artemis III and handed Bresnick, the next commander, the baton.

"You've got the controls," he says as the crowd applauds.

Bresnick says he is touched by the symbolism, telling the Artemis II crew that they "inspired people worldwide".

Then there's a moment of laughter when Douglas holds up the baton.

Bresnick says they're happy to be carrying the fire to the next mission

Josef Aschbacher, director general of the European Space Agency (ESA), heaps praise on Italian crew member Luca Parmitano and the ESA's partnership with Nasa.

"I had the privilege of witnessing the launch of Artemis II," he says. "It was an unforgettable moment. Artemis III will be a different mission, but no less remarkable."

To the crew, he says: "You will take a system of extraordinary complexity and make it work as one. In many ways you are unlocking the lunar landing itself."

He then lists Parmitano's achievements, including being a colonel of the Italian Air Force and the father of two daughters. He also survived a situation where his helmet filled with water, a situation which Aschbacher says will allow Parmitano to bring "a touch of Italian ease to the cockpit"

"To Nasa, to the United States of America. Thank you for your leadership and thank you for your partnership," he says.

"To the crew of Artemis III, you carry something important for all of us."

Artemis III Commander Randy Bresnick tells the crowd that the most important Artemis mission will be the next Artemis mission.

Bresnick, who has been with Nasa since 2004, will lead the Artemis III crew in their mission.

Newly named Artemis III mission specialist Frank Rubio also thanks his wife, kids, friends, family, and the Nasa community.

"You guys are the ones that make this happen, so thank you."

Mission pilot Luca Parmitano, an Italian astronaut from the European Space Agency, takes the microphone next. He began by apologising in case he becomes emotional while speaking.

"I am honoured by the role that I have been given," he says. "I am also very humbled by the task in front of us."

He praises his Italian education and opportunities he received from the Italian air force, space agency and the European Space Agency that have helped him reach this milestone.

Mission specialist Andre Douglas is the first of the astronauts up to speak.

"My heart, it is so warm, it is so full," he says.

He continues by thanking his parents and his wife, Rachel.

"Mum, thank you so much for believing in me," he says before praising his father's work ethic.

For his wife, he says: "I am so glad you are on this journey with us."

Norman D Knight, Nasa's director of flight operations, speaks after the Artemis III crew has just been announced.

"I am excited to welcome you as the next crew in the Artemis journey to successfully return to the Moon," he says.

"This mission will be one of the most complex that Nasa has undertaken, and we are counting on your courage and your dedication in fulfilling this critical role.".

Knight also thanks the crew members' families who "allow us to accomplish these ambitious goals for our country and humanity".

Here's some more information about the crew members:

• Bob Heintz will serve as a backup crew member. He is a test pilot who logged 170 days in space and can step into any role needed on the mission.
• Andre Douglas will be one of two mission specialists for the mission.
• Frank Rubio will be the second mission specialist.
• Luca Parmitano, of the Italian Space Agency, will be the pilot of Artemis III. He's spent more than 300 days in space.
• Randy Bresnik, a Nasa astronaut, will serve as the mission's commander.

Jessica Jensen, vice president at SpaceX, outlines the company's growth plans, saying several ships and boosters are currently being built as the Artemis program works toward putting people on the Moon via partnerships between Nasa and private companies.

"We are actively building out three more Starship launch pads in Florida and Texas," she continues.

"We believe this... is going to lead to unprecedented launch rates and achieving aircraft-like operations, which has always been our goal."

John Couluris, a vice president at Blue Origin, tells the crowd that Artemis III is a major step toward a Moon landing.

He says that Nasa and Blue Origin are working around the clock to be ready for launch in 2027.

Blue Origin, Couluris says, is very motivated to make the landing work, and despite a rocket blowing up on a Blue Origin launchpad recently, they have redoubled their efforts and are moving forward.

Parsons, from Nasa's Moon to Mars Program Office, is giving an overview of the Artemis III mission.

It will involve four crew members who will launch into low Earth orbit from the Kennedy Space Center in Florida. After their mission, they will splash down in the Pacific Ocean where they will be recovered by the a team from the US navy and Nasa.

"In total, we expect the mission to last around two weeks," he says. "This mission is deliberately designed to take calculated risks so that future crews will be safer and ultimately successful when we put boots on the lunar surface."

Parsons says this Artemis III test flight is meant to prove that Nasa can carry out "highly core" operations with its partners.

The mission is also meant to "reduce risk for our future crewed Moon missions", he says, "to ensure we will beat China back to the Moon".

"We will experiment with power, navigation, surface mobility, communications, and other critical systems as we learn what does and does not work in the extreme environment," he says.

Issacman concludes his remarks by saying the astronauts are carrying forward the hopes and dreams of the next generation.

"Artemis III crew, we wish you godspeed on the journey ahead," he says, "you carry the fire ...and the dreams of millions."

Jeremy Parsons then takes the stage to applaud the accomplishments of Artemis II, noting that Nasa demonstrated it could orbit the Moon and return astronauts safely to Earth.

He says this is why Nasa conducts test flights: to learn how to improve the Orion spacecraft.

This test flight, Parsons says, will prove Nasa can launch in sequence with its partners.

Isaacman is still at the podium. He says Nasa will not slow down and will be embarking on several projects simultaneousnessly.

The expectation of Nasa should be that we can do multiple things at once, he says, adding that Nasa will experiment as it learns what does and does not work for future missions.

"We can do this all while the Artemis III crew prepare for and undertake their important mission."

Isaacman says the Artemis III crew will launch into lower orbit to test the Orion spacecraft.

"They will rendezvous and dock with the Blue Origin lander, and then again with the SpaceX lander," Isaacman says.

"This seems like the beginning of the future that we imagine as children. This seems like the very beginning of Earth's first Starfleet to me."

The public will be able to follow along, he says, through all the "key milestones", as they test their reusable rockets, gather data, and implement improvements, "no earlier than this time next year".

Jared Isaacman tells the audience that Nasa will announce four astronauts who will head to space next.

He thanks US President Donald Trump and international partners for their work on the effort to return to space.

"We are returning to the moon," Isaacman says, to build a Moon base undertaking an "inspiring endeavor".

Artemis II "showed us the Moon again," he says, noting that the second Artemis mission helped reinvigorate the world's interest in space exploration.

Nasa is now passing the torch to Artemis III, Isaacman says.

Nasa's announcement of the Artemis III crew is about start any moment, from the Johnson Space Center in Texas.

As a reminder, the US space agency will name four individuals who will be part of a team to explore low Earth orbit next year.
