The four astronauts aboard Artemis II entered the Moon’s gravitational sphere of influence on Monday, continuing their journey toward the shadowed far side of the Moon – poised to become the farthest-traveling humans in history.

The crew is scheduled to wake at around 10:50 a.m. ET Monday for its sixth flight day. By approximately 7:05 p.m., the spacecraft is expected to reach a peak distance of about 406,773 kilometers from Earth – surpassing the record set by the Apollo 13 crew 56 years ago by more than 6,598 kilometers.
