Can you work out like an Artemis astronaut? The Artemis II astronauts exercised for roughly 30 minutes per day during their mission with a device called the flywheel, which provides the crew with a range of workouts without requiring any electrical power from the spacecraft.

During their lunar flyby, the Artemis II crew enjoyed the rare opportunity to experience a solar eclipse from their Orion spacecraft. With the Sun hidden behind the Moon, the astronauts were able to analyze the Sun’s outermost atmosphere, also known as the solar corona.

Big week for Artemis III 🚀 Just before NASA introduced the Artemis III crew, the SLS solid rocket booster segments arrived in Florida after a six-day rail journey from Utah. Later this year, teams will begin stacking the boosters that create 75% of the thrust needed at launch.

Behold: new and previously unseen imagery from our Artemis II mission! These images were captured on April 6, 2026, when the four astronauts aboard the Orion spacecraft conducted the lunar flyby portion of their ten-day journey.

One week to go! 🚀 @NASA will announce the Artemis III crew on June 9 at 11am ET (1500 UTC). Get ready to meet the four astronauts who will help advance the technologies needed to return humans to the Moon. More: t.co/AbNqKsLcvh 🔗 go.nasa.gov/4wV6Muy

Life inside Orion! The Moon joy was (and continues to be!) contagious as the Artemis II mission flew around the Moon and broke the record for farthest distance traveled from Earth.

During the Artemis II mission, astronauts had a fun time playing around with water in the weightlessness of space. Artemis II was @CSA_ASC astronaut @Astro_Jeremy's first spaceflight — so his crewmates taught him a lot about the physics of water in space.

After carrying the Artemis II crew 694,481 miles around the Moon and back, Orion is home at @NASAKennedy! Inside the Multi-Payload Processing Facility, teams will now inspect the spacecraft, retrieve post flight data, and remove excess fuel and coolant.
