Artemis II, NASA’s most daring mission in generations, launches to the Moon

KENNEDY SPACE CENTER, Fla.—Three Americans and one Canadian launched into orbit from Florida’s Space Coast on Wednesday, flying the most powerful rocket ridden by humans on the first leg of a nine-day voyage around the Moon.

Perched atop the 322-foot-tall (98-meter) Space Launch System rocket, the four astronauts lifted off from NASA’s Kennedy Space Center at 6:35 pm EDT (22:35 UTC).

Four hydrogen-fueled RS-25 engines and two solid rocket boosters flashed to life to push the nearly 6 million-pound rocket from its moorings at Launch Complex 39B. The engines and boosters collectively generated 8.8 million pounds of thrust, outclassing NASA’s Saturn V rocket used for Apollo lunar missions.
