Not even: Apollo 8[0] went into orbit around the moon (orbited 10 times), then left lunar orbit to return to Earth. This required mission-critical rocket burns both to enter (LOI) and exit (TEI) lunar orbit. Artemis II[1] is merely doing a "fly-by"; it'll never enter lunar orbit, a much less challenging/risky mission.

Thank you for those links. Haven’t read them in a while.

It really makes you appreciate what the Apollo program achieved. Really amazing.

LOI - lunar orbit insertion

TEI - trans-earth injection

For ill-informed people like me.

Space race notwithstanding, maybe less risky isn't such a bad idea.
