Artemis II fires rockets to leave Earth orbit, head for the moon

NASA’s Artemis II astronauts fired their engines and blazed toward the moon Thursday night, breaking free of the chains that have trapped humanity in shallow laps around Earth in the decades since Apollo.

The so-called translunar ignition came 25 hours after liftoff, putting the three Americans and a Canadian on course for a lunar fly-around early next week. Their Orion capsule bolted out of orbit around Earth right on cue and chased after the moon to nearly 250,000 miles (400,000 kilometers) away.

“Ladies and gentlemen, I am so, so excited to be able to tell you that for the first time since 1972 during Apollo 17, human beings have left Earth orbit,” NASA’s Lori Glaze announced at a news conference.

The engine firing was flawless, she noted.

Canadian astronaut Jeremy Hansen said he and his crewmates were glued to the capsule’s windows as they left Earth in the rearview mirror, taking in the “phenomenal” views. Their faces were pressed so tightly against the windows that they had to wipe them clean.

NASA had the Artemis II crew stick close to home for a day to test their capsule’s life-support systems before clearing them for lunar departure.

Now committed to the moon, the Artemis II test flight is the opening act for NASA’s grand plans for a moon base and sustained lunar living.

Commander Reid Wiseman, pilot Victor Glover, Christina Koch and Hansen will dash past the moon then hang a U-turn and zip straight home without stopping on land. In the process, they will become the farthest humans have ever traveled from Earth, breaking the Apollo 13 distance record set in 1970. They also may become the fastest during their reentry at flight’s end on April 10.

Mission Control gave the final go-ahead minutes before the critical engine firing, telling the astronauts that they were embarking on “humanity’s lunar homecoming arc” to bring them back to Earth. The capsule is relying on the gravity of Earth and the moon — termed a free-return lunar trajectory — to complete the round-trip figure-eight loop. The engine accelerated their capsule to more than 24,000 mph (38,000 kph) to shove them out of Earth’s orbit.

The next major milestone will be Monday’s lunar flyby.

Orion will zoom 4,000 miles (6,400 kilometers) beyond the moon before turning back, providing unprecedented and illuminated views of the lunar far side, at least for human eyes. 

NASA is counting on the test flight to kickstart the entire Artemis program and lead to a moon landing by two astronauts in 2028.
