Artemis II: Everything We Know as Orion Approaches the Far Side of the Moon

On day six of its mission, Artemis II is closing in on the far side of the moon. Meanwhile, the historic journey has not been without fascinating and curious stories, from the images and videos that its four crew members have shared with the world to the inevitable unforeseen events—including a tricky toilet situation.

A few hours before the crew begins its lunar flyby, here’s how things are going on Artemis II.

When Will They Reach the Far Side of the Moon?

While Artemis II won’t actually land on the moon (that won’t happen until Artemis IV), that does not make this mission any less compelling. Once the Artemis II astronauts finish flying over the dark side of the moon, they will have the historic distinction of being the humans who have traveled the farthest from Earth.

They will also test all the systems needed for future lunar missions, validating life support, navigation, spacesuits, communications, and other human operations in deep space.

But when are they supposed to reach this far-off point? First, the Orion capsule reached what is known as the moon’s “sphere of influence” on Sunday night. This is the point where the moon’s gravitational force is stronger than the force of the Earth.

At present, Orion is circling the moon. Once the capsule is on the dark side of the moon, approximately 7,000 kilometers from the surface, communications with Earth will be interrupted. For six hours, they will be able to view the far side of the moon, something no human being has ever seen with their own eyes—not even the astronauts of the Apollo program, as this region of the moon was always too dark or difficult for them to reach.

That six-hour flyby of the dark side of the moon is expected to begin Monday, April 6, at 2:45 pm EDT and 7:45 pm London time.

After that, the capsule will use the moon’s gravity to propel itself back to Earth. Splashdown, when the astronauts reach Earth, is scheduled for April 10 in the Pacific Ocean, not far from the coast of California, the tenth day of the mission.

Remember that you can follow the live broadcast of the Artemis II mission from NASA’s official channels.

What Has Happened so Far?

Since its successful launch on April 1 from Kennedy Space Center, the Artemis II crew has shared several spectacular photos, such as the featured image in this post, which shows mission specialist Christina Koch looking down at Earth through one of Orion’s main cabin windows.

This incredible photo of a Earth, taken on April 2, went viral on social media, referencing the famous “Blue Marble” image captured by the Apollo 17 astronauts in 1972.
