NASA’s Artemis II mission has launched four astronauts on a groundbreaking journey around the Moon, marking significant milestones in space exploration.
The numbers
The Artemis II mission has successfully launched four astronauts on a journey around the Moon, marking a significant milestone in NASA’s efforts to return humans to lunar exploration. As of April 4, 2026, the Orion spacecraft was positioned more than 160,000 miles from Earth and less than 120,000 miles from the Moon.
On this date, the crew, which includes NASA astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen, passed the halfway point of their voyage, achieving this milestone just two days, five hours, and 24 minutes after liftoff. Reid Wiseman expressed the awe of the experience, stating, “It was really great to wake up this morning and look out the window and see the full moon off the front of the vehicle.”
The Artemis II mission is set to conduct a lunar flyby on April 6, 2026, during which the Orion spacecraft will fly 4,066 miles away from the Moon at its closest approach. This mission is particularly notable as it is expected to surpass the Apollo 13 distance record by an impressive 4,102 miles.
During their journey, the crew has been actively engaged in various tasks, including practicing CPR in space and testing medical equipment from the Orion medical kit. Christina Koch remarked on the stunning view, saying, “We can see the Moon out of the docking hatch right now, it is a beautiful sight.” This hands-on training is crucial for ensuring the crew’s preparedness for any potential medical emergencies during the mission.
As the Orion spacecraft approaches the Moon, it will experience a communications blackout when it passes behind the lunar surface. This is a standard procedure for missions of this nature, as the spacecraft will be out of range of Earth-based communication systems. During this time, Mission Control will remind the crew, “You are now closer to the moon than you are to us on Earth.”
In addition to the lunar flyby, the crew will have the unique opportunity to observe a solar eclipse from space during their mission. This rare event adds an exciting element to their journey, showcasing the beauty and wonder of space exploration.
Furthermore, the Orion Artemis II Optical Communications System has already surpassed 100 gigabytes of data downlinked during the mission, highlighting the advanced technology being utilized in this groundbreaking endeavor. The astronauts are currently on a ‘free-return’ trajectory, using the Moon’s gravity to return to Earth without propulsion, which adds to the mission’s efficiency and safety.
The Artemis II mission is a pioneering journey around the Moon, following the Artemis I mission. Observers are eagerly anticipating the upcoming lunar flyby, which promises to be a historic moment in space exploration. Details remain unconfirmed regarding any additional findings or experiences the crew may encounter during their flyby.
