Carrying three Americans and one Canadian, the 32-story rocket rose from NASA’s Kennedy Space Center where tens of thousands gathered to witness the dawn of this new era. Crowds also jammed the surrounding roads and beaches, reminiscent of the Apollo moonshots in the 1960s and ’70s. It is NASA’s biggest step yet toward establishing a permanent lunar presence.
“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 right before liftoff. “Good luck, Godspeed Artemis II. Let’s go.”
Artemis II set sail from the same Florida launch site that sent Apollo’s explorers to the moon so long ago. The handful still alive cheered this next generation’s grand adventure as the Space Launch System rocket thundered into the early evening sky, a nearly full moon beckoning some 248,000 miles (400,000 kilometers) away.
Five minutes into the flight, Commander Reid Wiseman saw the team’s target: “We have a beautiful moonrise, we’re headed right at it,” he said from the capsule. On board with him are pilot Victor Glover, Christina Koch and Canada's Jeremy Hansen.
“NASA is back in the business of sending astronauts to the moon," NASA Administrator Jared Isaacman told reporters following liftoff, calling the half-century hiatus a brief intermission.
Tensions high in the hours leading up to launch
Tensions were high earlier in the day as hydrogen fuel started flowing into the rocket. Dangerous hydrogen leaks erupted during a countdown test earlier this year, forcing a lengthy flight delay.
To NASA’s relief, no significant hydrogen leaks occurred. The launch team loaded more than 700,000 gallons of fuel (2.6 million liters) into the 32-story Space Launch System rocket on the pad, a smooth operation that set the stage for the Artemis 11 crew to board.
Then NASA had to overcome a flurry of last-minute technical issues — bad battery sensors and an inability to get commands through to the rocket's flight termination system. In both cases, the issues were quickly resolved, allowing the launch to proceed.
What's on tap for 10-day test flight?
The astronauts will stick 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 won’t pause for a stopover or orbit the moon like Apollo 8’s first lunar visitors did so famously on Christmas Eve 1968, reading from Genesis. But they stand to become the most distant humans ever when their capsule zooms past the moon and continues another 4,000 miles beyond, before making a U-turn and tearing straight home to a splashdown in the Pacific.
Once settled in a high orbit around Earth, the astronauts assumed manual control and practiced steering their capsule around the rocket’s detached upper stage, venturing as close as 33 feet. NASA wants to know how Orion handles in case the self-flying feature fails and the pilots need to take control.
