At long last, we're going to learn which astronauts will fly NASA's first crewed mission to the moon of the Artemis generation.

Today, April 3, NASA and the Canadian Space Agency will announce the four astronauts who will fly on the Artemis 2 mission around the moon in 2024. That crew is expected to include one Canadian astronaut and three NASA astronauts, but exactly who is yet to be revealed.

NASA will announce the crew in an event at Ellington Field near the Johnson Space Center in Houston, Texas at 11 a.m. EDT (1500 GMT). Space.com staff writer Elizabeth Howell is on the scene at the event alongside contributor Robert Pearlman of collectSPACE.com.

You'll be able to watch it live on Space.com, as well as at the top of this page at start time.

While we wait, here's a nifty trailer from NASA for today's Artemis 2 crew reveal.

NASA Artemis 2 moon crew announcement underway

NASA's Artemis 2 moon astronaut crew reveal is underway live on NASA TV.

Speaking before a huge crowd at the Ellington Field in Houston, NASA's chief astronaut Joe Acaba began by inviting the entire astronaut corps to the stage.

"Your Artemis 2 astronauts are in the room with you ... I am not one of them," he said.

Canada's government minister responsible for space, François-Philippe Champagne, hailed the 60 year partnership of NASA + CSA and Canada's contribution of the CanadArm3 for the Gateway station around the moon: "We're going to the moon!" he cheered.

NASA Administrator Bill Nelson is now preparing to introduce the crew.

The four astronauts of NASA's Artemis 2 mission are thrilled, to say the least, to be on the crew that will send the first humans to the moon in more than 50 years. You can read our full story here.

Set to launch on a Space Launch System megarocket in 2024, NASA astronauts Reid Wiseman, Victor Glover, Christina Koch and Jeremy Hansen of the Canadian Space Agency will fly around the moon, much like Apollo 8, on their Orion spacecraft.

Here's what they had to say of the mission today:

Commander Reid Wiseman: "This is a global effort, Artemis 2, and it's only going to get larger with Artemis 3 and beyond as we get private spaceflight involved. SpaceX is building our lander for Artemis 3. So to the NASA workforce, to our program managers, our center directors that are here, the amazing political support that we feel right now to bring our country together to bring our entire world together to go explore to get to Mars and beyond, we say a huge thank you."

Pilot Victor Glover: "We need to celebrate this moment in human history. Because Artemis two is more than a mission to the moon and it's more than a mission that has to happen before we send people to the surface of the moon. It is the next step on the journey that gets humanity to Mars.

"Human spaceflight is like a relay race, and that baton has been passed generation to generation and from crew member to crew member from the Gemini, Mercury, Gemini, Apollo, Apollo Soyuz, Skylab Mir, the shuttle, International Space Station, commercial crew and and now the Artemis missions. We understand our role in that. And when we have the privilege of having that baton. We're going to do our best to run a good race to make you proud. I pray that God will bless this mission. But I also pray that we can continue to serve as a source of inspiration for cooperation and peace, not just between nations, but in our own nation."

Mission specialist Christina Koch:  "When I think about this mission, that's a relay race with international partners, it's all so awesome in and of itself.

"We are going to launch for Kennedy Space Center to the work of the exploration Ground Systems team. We're going to hear the words go for launch on top of the most powerful rocket NASA's ever made the Space Launch System, and we're gonna ride that rocket for eight minutes into Earth orbit. We're not going to go to the moon right away. We're gonna stay in an amazing high orbit, reaching a peak of tens of thousands of miles while we test out all the systems on Orion and see how it maneuvers in space. And then if everything was good, we're heading to the moon.

"It will be a four day journey, going a quarter of a million miles, continuing to test out every bit of Orion going around the far side of the moon, heading home going through the Earth's atmosphere at over 25,000 miles per hour and splashing down in the Pacific. So am I excited? Absolutely. But my real question is Are you excited? I asked that because the one thing I'm most excited about is that we are going to carry your excitement, your aspirations, your dreams with us on this mission. Artemis to your mission."

Mission specialist Jeremy Hansen: "Our scientists or engineers, the Canadian Space Agency, the Canadian Armed Forces across government, all of our leadership working together under a vision to take step by step and all of those have added up to this moment where a Canadian is going to the moon with our international partnership and it is glorious."

Artemis 2 mission benefits from Canadian winter experience

Cold weather is helping to boost the fortunes of Canada in space, including its contributions to Artemis 2.

Astronaut Jeremy Hansen will the first non-American to leave low Earth orbit, alongside three NASA crewmates, no earlier than 2024. Canadian leader and Prime Minister Justin Trudeau argues that Canada's winter experience is one big reason for its success in space.

Trudeau emphasized that working in Canada's north helped with numerous kinds of technology, including the Canadarm robotic arm series that has provided Canadian astronaut seats for nearly 40 years.

The Arctic in particular represents "some of the harshest environments" available to humans, and Trudeau joked that when asked about why Canada does so well in space, he responds: "Obvious. Winter."

A moon astronaut recently honored the decades of supersonic trainer work that NASA has put in with its T-38s.

Artemis 2 Canadian Space Agency (CSA) astronaut Jeremy Hansen praised the supersonic T-38 trainer jet for its ability to keep astronauts on their toes while in flight. "We use these airplanes because they're challenging," Hansen said in a video released Tuesday (July 18) on the CSA's social media channels.

Manufacturer Northrop Grumman says more than 72,000 U.S. Air Force pilots have trained in the T-38 since it first rolled off the line in 1961. Though it was only manufactured until 1972, more than 500 continue to be used by both the Air Force and NASA.

The Canadian Space Agency may bring the third Canadian woman into space as soon as 2024, should she be needed for a moon mission.

Fire scientist Jenni Gibbons was named Tuesday (Nov. 22) as backup for Jeremy Hansen, the CSA astronaut flying around the moon with Artemis 2 in 2024. The CSA is a signatory to the NASA-led Artemis Accords that has two purposes: peaceful space exploration norms and for some participants, moon missions.

That wasn't the only big space news for CSA on Tuesday. Canada typically receives missions every six years based on its ISS contributions, and current spacecraft capacity. The next long-duration mission will be with Joshua Kutryk, a test pilot with the Royal Canadian Air Force, will fly on the first operational Boeing Starliner mission in 2025 for a half-year mission to the ISS.

NASA astronaut Andre Douglas will serve as backup for the three U.S. astronauts on the Artemis 2 round-the-moon flight, the agency announced today (July 3).

Douglas will back up commander Reid Wiseman, pilot Victor Glover and mission specialist Christina KochCanadian Space Agency (CSA) astronaut Jeremy Hansen, who is also a mission specialist on Artemis 2, already has a backup: astronaut Jenni Gibbons, also with CSA.

"I've always been fascinated with new things. I like to develop things," Douglas told Space.com in March about the Artemis program, which later this decade aims to put astronauts on the moon's surface for the first time since 1972. "I really believe in pushing ourselves, in understanding what is our true potential: both me as an individual, [and] within all of us as a species."

"This is the perfect place to be, where we're going to push that boundary," he said.

Artemis 2 core stage to arrive at KSC

NASA will livestream the arrival of the Artemis 2 core stage at NASA's Kennedy Space Center Wednesday (July 23) on X, the agency announced. The livestream will start at 9:30 a.m. EDT (1330 GMT).

NASA's Space Launch System (SLS) Artemis 2 booster left the agency's Michoud Assembly Facility, in New Orleans on July 16 for a journey on NASA's Pegasus barge to KSC, near Orlando. The core stage has reached the Floridian shore as of Monday (July 21), but has not yet gone on to KSC grounds, according to social media posts.

Artemis 2 is the first human lunar mission since Apollo 17 in 1972 and plans to send four astronauts around the moon no earlier than September 2025.

An astronaut crew's rocket made its last major journey on Earth before blasting off for the moon.

The core stage of Artemis 2's rocket came to NASA's Kennedy Space Center (KSC) in Florida on Tuesday (July 23). The rocket stage was offloaded from NASA's Pegasus barge, which shipped the rocket stage 900 miles (1,450 km) by water from NASA's Michoud Assembly Facility in New Orleans, in a seven-hour operation aided by remote controlled vehicles known as self-propelled modular transporters.

The 212-foot (65-meter) stage then made the half-mile (0.8 km) journey to NASA's Vehicle Assembly Building where it will eventually be joined to the rest of the Space Launch System rocket for a launch no earlier than September 2025.
