Four astronauts They undertook a high-risk flight around the Moon on Wednesday, humanity’s first lunar voyage in more than half a century and the exciting start of NASA’s push toward a moon landing in two years.
With three Americans and one Canadian on board, the 32-story rocket took off from the Kennedy Space Center, where tens of thousands of people gathered to witness the beginning of this new era. Crowds also packed nearby roads and beaches, evoking the launches of the Apollo program in the 1960s and 1970s. This represents NASA’s biggest step yet toward establishing a permanent presence on the Moon.
“On this historic mission, you carry with you the heart of this Artemis team, the bold spirit of the American people and our partners around the world, and the hopes and dreams of a new generation,” launch director Charlie Blackwell-Thompson told the crew just before liftoff. “Good luck, Artemis II. Underway.”
Artemis II took off from the same location in Florida that sent the Apollo explorers to the Moon so long ago. The few still alive from that era celebrated this great new adventure as the Space Launch System rocket roared into the sunset sky, with a nearly full Moon beckoning them some 248,000 miles away.
1/12 | Just hours away: this is how the Artemis II astronauts arrived at the launch pad. The crew arrived at the Launch Complex four hours before the estimated takeoff after completing the walk at the Kennedy Space Center in Cape Canaveral, which “every NASA astronaut has done since the Apollo 7 mission in 1968.” -Chris O’Meara
Five minutes into the flight, the commander Reid Wiseman He saw the team’s objective: “We have a beautiful moonrise, we are going straight towards it,” he said from the capsule. The pilot travels with him Victor Glover, Christina Koch and the Canadian Jeremy Hansen. It is the most diverse lunar crew in history, with the first woman, the first person of color and the first non-US citizen aboard the new Orion capsule of the POT.
“NASA returns to the activity of sending astronauts to the Moon” after more than half a century that he described as a “brief” hiatus, NASA administrator Jared Isaacman told the press shortly after takeoff.
Pre-launch tension
Tensions rose early in the day when hydrogen fuel began to enter the rocket. Earlier this year, dangerous hydrogen leaks occurred during a countdown test, forcing the flight to be delayed.
To NASA’s relief, no significant hydrogen leaks occurred. The launch team loaded more than 700,000 gallons of fuel onto the 32-story Space Launch System rocket on the pad, a smooth operation that set the stage for boarding of the Artemis II crew.
Next, NASA had to overcome a series of last-minute technical problems: faulty battery sensors and the inability to transmit commands to the rocket’s flight termination system. In both cases, the problems were resolved quickly, allowing the launch.
What is planned for the 10-day test flight?
The astronauts will stay close to home for the first 25 hours of their 10-day test flight, checking out the capsule in orbit around Earth before firing the main engine that will propel them to the Moon.
They will not stop and orbit the Moon as the first Apollo 8 lunar visitors did on Christmas Eve 1968, reading Genesis. But they will become the most distant human beings in history when their capsule passes the Moon and continues 6,400 kilometers beyond, before turning around and returning directly home to splash down in the Pacific.
Once settled into high orbit around Earth, the astronauts prepared to take manual control and practice steering their capsule around the rocket’s detached upper stage, venturing to within 33 feet. NASA wants to know how Orion handles itself in case the self-flight function fails and pilots have to take control.

Amazing view
Four days later, during the lunar flyby, the Moon will appear to be the size of a basketball held at arm’s length. Astronauts will take turns looking through Orion’s windows with cameras. If the lighting is adequate, they will be able to see features never seen with human eyes. They will also capture fragments of a total solar eclipse, donning eclipse glasses when the moon briefly blocks the sun from their perspective and the corona is revealed.
All of NASA’s lunar plans – a wave of launches in the coming years leading to a sustainable lunar base for astronauts assisted by rovers and drones – depend on Artemis II working well.
It’s been more than three years since Artemis I, the only other time NASA’s SLS rocket and Orion capsule have taken to the air. With no one on board, the Artemis I capsule lacked life support equipment and other essentials for the crew, such as a water dispenser and a toilet.
These systems are now making their debut in space with Artemis II, which increases the risk. That’s why NASA waits a full day before committing Wiseman and his crew to a four-day trip to the Moon and four days back.
The pod toilet no longer works. Koch reported to Mission Control that it shut down seconds after she activated it. Mission Control advised him to use a portable bag-and-funnel system – CCU, short for Collapsible Contingency Urinal – for the time being while engineers studied how to fix the so-called lunar toilet.
“The stakes have always been high on this mission,” NASA’s Lori Glaze said before launch. But teams are even more “encouraged” now that the space agency is finally accelerating the pace of lunar launches and focusing on surface operations, seismic changes that Isaacman recently announced.
A new beginning
With half the world’s population still unborn when NASA’s 12 moonwalkers left their boot prints in the gray lunar dust, Artemis offers a new beginning, NASA science mission chief Nicky Fox said earlier this week.
“There are many people who don’t remember Apollo. There are generations that weren’t alive when Apollo was launched. This is their Apollo,” says Fox, who was 4 years old when Apollo 17 closed the era.
This time NASA has set itself a long-term goal. Unlike Apollo, which focused on flags and fast footprints in a dizzying race against the Soviet Union, Artemis strives for a sustainable lunar base elaborate enough to satisfy even die-hard sci-fi fans. But make no mistake: Isaacman and the Trump Administration want the next boot prints to be made by Americans, not the Chinese.
Until Isaacman’s program change, the Artemis III was crawling toward a lunar landing no earlier than 2029. The billionaire astronaut decided to install a new Artemis III in 2027 so that astronauts could practice docking their Orion capsule with a lunar lander in orbit around Earth. The astronauts’ momentous landing near the Moon’s south pole has been moved to Artemis IV in 2028, two years before the planned arrival of a Chinese crew.
Like Apollo 13 – the only failed lunar landing by astronauts – Artemis II will use a free-return lunar trajectory to reach home with the pull of gravity and a minimum of gas. The Moon’s and Earth’s gravity will provide most of the thrust needed to keep Orion in its back-and-forth figure-eight loop.
Inherent dangers
The danger is right there for Artemis II. NASA has refused to release its risk assessment for the mission. Managers say it is better than 50-50 (the usual odds for a new rocket), but it is not known how much more.
The SLS rocket suffered a leak of flammable hydrogen during ground testing, a recurring problem that engineers still don’t fully understand. Hydrogen leaks and helium blockages paralyzed the flight for two months, after years of delays and cost overruns. Both problems also thwarted the Artemis I, whose capsule returned with excessive heat shield damage. To NASA’s relief, Wednesday’s countdown showed no leaks.
Beating the Soviet Union to the Moon made the enormous risks acceptable for Apollo, said Charlie Duke, one of only four survivors of the moon walk.
“I’m cheering you on,” Duke said in a note to Wiseman and his crew before their flight.
During a press conference over the weekend, Koch emphasized that humanity’s path to Mars passes through the Moon, the testing ground for points beyond.
“We firmly hope that this mission is the beginning of an era in which everyone, all the inhabitants of Earth can look at the Moon and think of it as a destination too,” he declared.
Glover added: “It’s the history of humanity. Not the history of black people, not the history of women, but the history of humanity.”
