Four astronauts blasted off on a high-stakes journey around the moon on Wednesday, marking humanity’s first lunar mission in more than 50 years and a major step in NASA’s plan to land humans on the moon again within two years.
The 32-storey Space Launch System rocket lifted off from NASA’s Kennedy Space Center carrying three Americans and one Canadian, as tens of thousands of spectators gathered to witness the historic launch. Roads and nearby beaches were packed with onlookers, evoking scenes from the Apollo-era moon missions of the 1960s and 1970s. The mission represents NASA’s most significant progress yet toward building a sustained human presence on the moon.
“On this historic mission, you take with you the heart of this Artemis team, the daring spirit of the American people and our partners across the globe, and the hopes and dreams of a new generation,” launch director Charlie Blackwell-Thompson told the crew moments before liftoff. “Good luck, Godspeed Artemis II. Let’s go.”
Artemis II departed from the same launch site used during the Apollo missions. Surviving Apollo astronauts watched as the rocket roared into the evening sky, heading toward a nearly full moon about 248,000 miles away.
Five minutes after launch, commander Reid Wiseman spotted the moon. “We have a beautiful moonrise, we’re headed right at it,” he said from the capsule. He is joined by pilot Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen. The crew is the most diverse ever sent on a lunar mission, including the first woman, the first person of colour and the first non-American astronaut to travel to the moon aboard NASA’s Orion capsule.
“NASA is back in the business of sending astronauts to the moon,” NASA Administrator Jared Isaacman said after liftoff, describing the long gap since the last mission as a brief pause.
Launch challenges overcome
Tension surrounded the launch preparations earlier in the day as hydrogen fuel began flowing into the rocket. Previous tests had revealed dangerous hydrogen leaks, causing significant delays.
However, NASA reported no major leaks this time, allowing more than 700,000 gallons of fuel to be loaded smoothly. Engineers also resolved last-minute technical issues involving battery sensors and communication with the rocket’s flight termination system, clearing the way for liftoff.
Details of the 10-day mission
The astronauts will remain in orbit around Earth for the first 25 hours of their 10-day mission, conducting system checks before firing the main engine to begin their journey to the moon.
Unlike Apollo 8, they will not enter lunar orbit. Instead, their capsule will fly past the moon and travel about 4,000 miles beyond it, making them the most distant humans ever, before looping back to Earth for a Pacific Ocean splashdown.
While in Earth orbit, the crew practiced manual control of the capsule, maneuvering close to the rocket’s upper stage to test handling in case of automated system failure.
Unique views and experiments
During the lunar flyby, the moon will appear as large as a basketball held at arm’s length. The astronauts will observe and photograph its surface, potentially capturing views never before seen by humans. They will also witness part of a total solar eclipse, using protective glasses as the moon briefly blocks the sun.
NASA officials said the success of Artemis II is critical to future missions aimed at establishing a long-term lunar base supported by robotic systems.
It has been more than three years since Artemis I, which flew without a crew. Artemis II introduces life-support systems, including water and waste management, increasing mission complexity. NASA plans to wait a full day before committing to the full lunar trajectory.
However, technical issues have already emerged. Christina Koch reported that the capsule’s toilet malfunctioned shortly after activation. Mission control advised using a backup system while engineers work on a solution.
“There’s always been a lot riding on this mission,” NASA official Lori Glaze said before launch, adding that teams are now more motivated as the agency accelerates its lunar programme.
A new era of lunar exploration
NASA officials say Artemis marks a new chapter in space exploration, especially for generations that did not witness the Apollo missions. “This is their Apollo,” said NASA science chief Nicky Fox, noting that many people alive today were not born during the original moon landings.
Unlike the short-term Apollo missions driven by Cold War competition, Artemis aims to establish a sustainable human presence on the moon, with ambitions extending to Mars.
NASA is also racing against China’s lunar ambitions. The current plan targets a return to the moon’s surface near the south pole by 2028 under Artemis IV, following earlier preparatory missions.
Like Apollo 13, Artemis II will use a free-return trajectory, relying on the gravitational pull of the Earth and moon to guide the spacecraft on its path.
Risks remain
Despite the excitement, NASA acknowledges significant risks. The agency has not disclosed detailed risk assessments, though officials say the mission’s success probability is better than 50 percent, typical for a new rocket system.
The Space Launch System has faced persistent issues, including hydrogen leaks and delays, as well as damage observed in Artemis I’s heat shield. While Wednesday’s launch proceeded without leaks, uncertainties remain.
Apollo astronaut Charlie Duke expressed support for the mission, sending a message of encouragement to the crew.
During a recent briefing, Koch highlighted the mission’s broader significance, saying the journey to Mars begins with returning to the moon.
“It is our strong hope that this mission is the start of an era where everyone on Earth can look at the moon and think of it as also a destination,” she said.
Victor Glover added, “It’s the story of humanity — not Black history or women’s history, but human history.”
