NASA back in lunar voyages with launching of Artemis II

Four astronauts embarked on a high-stakes flight around the moon Wednesday, humanity's first lunar voyage in more than half a century and the thrilling leadoff in NASA's push toward a landing in two years.

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. It was the most diverse lunar crew ever with the first woman, person of color and non-U. S. citizen riding in NASA's new Orion capsule.

"NASA is back in the business of sending astronauts to the moon" after more than half a century that he called a "brief" intermission, NASA Administrator Jared Isaacman told reporters shortly after liftoff.

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 II 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.
