The engine firing provided a slingshot-like boost to the Orion capsule, speeding it up to some 25,000 mph, the velocity needed to break free of Earth's gravitational clasp for a trek to the moon.

The new Artemis II images — coupled with initial shots of the spacecraft hurtling through Earth's orbit, surrounded by glittering, galactic ice — have rendered much of the public awestruck, feeds flooding over with an overwhelming sense of emotion as the astronauts look back at our home.

NASA's latest photos from the Artemis II mission show Earth in stunning details as the astronauts near a milestone distance of 100,000 miles away.

The Artemis II astronauts continued their long coast to the moon, capturing stunning photos along the way.

Photos of Earth taken by the Artemis 2 astronauts reveal their perspective as they zoom farther away from our home planet than any have gone before.

Exactly when and how plate tectonics started, however, is a matter of debate. Now, in a study published March 19 in the journal Science, rock samples from Western Australia hint that the Earth’s crust may have been moving as early as 3.48 billion years ago, roughly one billion years after our planet formed.

The Artemis II astronauts, after saying goodbye to family and friends, were strapped into their seats aboard the Orion spacecraft by early afternoon, hours before the launch window opened at 6:24 p.m. Eastern time. As the astronauts sat, NASA continued with checks to ensure the safety of the crew before liftoff.

Orion and its four-person crew have been orbiting Earth since shortly after launch on Wednesday. Next up, a critical engine burn that will send the astronauts to the moon
