Four astronauts blasted off from Florida on Wednesday on NASA’s Artemis II mission, a high‑stakes 10-day trip around the moon that marks the United States’ boldest step yet toward returning humans to the lunar surface this decade before China’s first crewed landing.The 32-storey rocket rose from NASA’s Kennedy Space Center in Cape Canaveral, where tens of thousands gathered to witness the liftoff.The Artemis II crew – NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen – are set for a nearly 10-day journey around the moon and back, taking them farther into space than humans have travelled in decades.“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,” said Charlie Blackwell-Thompson, the launch director. “Good luck, Godspeed Artemis II. Let’s go.”Five minutes into the flight, Wiseman, the commander, saw the team’s target: “We have a beautiful moonrise, we’re headed right at it,” he said from the capsule.The astronauts will spend the first one to two days in high Earth orbit carrying out extensive systems checks, including testing Orion’s life-support, propulsion, navigation and communications systems to make sure the spacecraft is ready for deep space.
