'Welcome home, Artemis': Crew celebrates historic 10-day moon mission
After their historic lunar flyby, the crew safely splashed down in the Pacific.
NASA's Artemis II mission lifted off on April 1 at 6:35 p.m. ET from the Kennedy Space Center in Florida.
The four-person crew completed a 695,081-mile, 10-day journey around the moon, also known as a lunar fly-by.
A "textbook" splashdown took place at 8:07 p.m. ET on Friday, April 10.

Breaking down Artemis II moon mission terms, jargon and what they mean
Following the path of Artemis II may be confusing as the astronauts, mission control and others use specific jargon and phrases.
Here are explanations of some of the terminology people may hear over the course of the mission:
Translunar injection burn
The translunar injection burn is the final step that sends the crew on the path to the moon, committing the Orion spacecraft to the remainder of its 10-day mission.
Lasting just minutes, it's a single-engine firing that propels the spacecraft out of Earth's orbit and on a "free-return trajectory."
Universal waste management system
The universal waste management system, otherwise known as a space toilet, is located inside a stall just like in a public restroom on Earth, according to NASA.
Space toilets use air flow to pull urine and feces away and into receptacles, which are stored for disposal. The astronauts have a handlebar to hold themselves down while using the toilet in the absence of gravity.

Get to know Christina Koch, the 1st female astronaut to travel around the moon
NASA astronaut Christina Koch is making history as the first woman to travel around the moon.
Koch, 47, is among the four-person crew aboard the Orion spacecraft for NASA's Artemis II mission, which lifted off Wednesday evening from the Kennedy Space Center in Florida for a 10-day journey.
Koch, who was born in Grand Rapids, Michigan, and grew up in Jacksonville, North Carolina, is no stranger to record-setting NASA missions.
Koch was first selected as a NASA astronaut in 2013. In December 2019, she set the record for the longest single spaceflight by a woman, spending 328 consecutive days in space, according to NASA, and was part of the first all-female spacewalk in October 2019 with Jessica Meir.
