Artemis II Astronauts Reach Halfway Point to the Moon
- NASA's Artemis II crew passed the halfway point between Earth and the moon on Saturday, April 4, 2026, as they continue a historic lunar flyby mission.
- The Orion spacecraft is carrying a crew of four: Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen.

NASA’s Artemis II crew passed the halfway point between Earth and the moon on Saturday, April 4, 2026, as they continue a historic lunar flyby mission. This journey marks the first time humans have traveled toward the moon in more than five decades.
The Orion spacecraft is carrying a crew of four: Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen. The mission launched from the Kennedy Space Center in Florida on April 1, 2026, at 6:35 p.m. EDT, propelled by the Space Launch System (SLS), which is the most powerful rocket ever built by NASA.
Mission Trajectory and Technical Milestones
The mission sequence began with the crew spending the first 24 hours in a high Earth orbit to verify manual piloting capabilities and test critical life-support systems. Following these checks, the spacecraft executed the Trans-Lunar Injection (TLI), an engine burn that acted as a cosmic slingshot to push the Orion capsule out of Earth’s gravitational pull and onto a four-day trajectory toward the lunar far side.
According to NASA’s online dashboard, the spacecraft was more than 229,000 kilometers (142,000 miles) from Earth early on April 4, 2026. Astronaut Christina Koch reported that the crew reached the halfway milestone approximately two days, five hours, and 24 minutes after liftoff.
Commander Reid Wiseman commented on the scale of the operation during a radio check-in with Mission Control, stating, I’ve got to tell you, there is nothing normal about this. Sending four humans 250,000 miles away is a herculean effort, and we are now just realizing the gravity of that.
Onboard Operations and Observations
The interior of the Orion spacecraft, which is comparable in size to a large camper van, serves as a hub for science experiments and systems maintenance. The crew is tasked with the constant monitoring of oxygen scrubbers and radiation shielding to ensure spacecraft integrity during deep space transit.

As the crew moved further from Earth, they captured and downlinked the first images of the mission. These photographs include a curved slice of Earth seen through the capsule’s windows and a full portrait of the globe featuring deep blue oceans, billowing white clouds, and a green aurora. Other imagery captured the terminator, the dividing line between the planet’s day and night sides.
Astronaut Christina Koch noted around 11 p.m. On Friday, April 3, 2026, that the moon was visible through the docking hatch, describing it as a beautiful sight.
Next Phases of the Mission
The Artemis II crew is currently preparing for their first correction burn and is awaiting their lunar observation assignments. The mission is scheduled to reach its destination on Monday, April 6, 2026, for the planned lunar flyby.
