The NASA’s Artemis II mission is set to reach a defining milestone on April 6, as astronauts prepare for a historic lunar flyby that will offer a rare view of the Moon’s far side, a region never visible from Earth.
The NASA mission, which launched on April 1, has already travelled more than 206,000 miles from Earth, placing the crew on a trajectory that marks one of the most ambitious human spaceflight journeys in recent decades.
By April 5 morning (ET), Orion was approximately 206,482 miles from Earth and about 75,000 miles from the Moon, travelling at speeds nearing 1,771 miles per hour. By April 6, the spacecraft is expected to be significantly closer, aligning precisely for its planned lunar flyby window.
Mission control teams in Houston are closely tracking the spacecraft’s position using real-time telemetry, ensuring that all systems remain optimal for the critical manoeuvres ahead.
During a carefully calculated six-hour window, the spacecraft, Moon, and Sun will align to provide astronauts with a direct view of the Moon’s far side. This region, often referred to as the “dark side,” remains permanently hidden from Earth due to tidal locking.
The flyby is not just a visual milestone but also a technical one. It will test navigation, communication, and spacecraft performance in deep space conditions, all of which are crucial for future missions.
The trajectory correction burn conducted earlier ensures the spacecraft is on the precise path needed for this alignment, highlighting the importance of the adjustments carried out on April 5.
On April 5, the crew focused on:
The astronauts, Reid Wiseman, Victor Glover, Christina Hammock Koch, and Jeremy Hansen, are expected to remain engaged in monitoring systems and capturing observations during the flyby.
NASA’s long-term roadmap includes landing astronauts on the Moon in later missions, with Artemis IV currently targeted for more advanced lunar operations later in the decade.
The ability to send astronauts safely around the Moon and back is a foundational step toward more complex missions, including long-duration stays on the lunar surface and eventual journeys to Mars.
For the Artemis II crew, the moment they glimpse the Moon’s far side will symbolise both a scientific achievement and a continuation of humanity’s exploration legacy.

Where is Artemis II now?
As the mission progresses into its sixth day in space, the Orion spacecraft continues to move deeper into lunar space.By April 5 morning (ET), Orion was approximately 206,482 miles from Earth and about 75,000 miles from the Moon, travelling at speeds nearing 1,771 miles per hour. By April 6, the spacecraft is expected to be significantly closer, aligning precisely for its planned lunar flyby window.
Mission control teams in Houston are closely tracking the spacecraft’s position using real-time telemetry, ensuring that all systems remain optimal for the critical manoeuvres ahead.
What is the plan for April 6?
April 6 marks the most anticipated phase of the Artemis II mission, the lunar flyby.During a carefully calculated six-hour window, the spacecraft, Moon, and Sun will align to provide astronauts with a direct view of the Moon’s far side. This region, often referred to as the “dark side,” remains permanently hidden from Earth due to tidal locking.
The flyby is not just a visual milestone but also a technical one. It will test navigation, communication, and spacecraft performance in deep space conditions, all of which are crucial for future missions.

Crew activities leading into the flyby
In preparation for this key moment, astronauts have followed a tightly structured schedule.On April 5, the crew focused on:
- Testing the Orion Crew Survival System suits, designed for high-risk mission phases
- Conducting onboard system checks to validate spacecraft performance
- Executing a trajectory correction burn to refine their flight path
The astronauts, Reid Wiseman, Victor Glover, Christina Hammock Koch, and Jeremy Hansen, are expected to remain engaged in monitoring systems and capturing observations during the flyby.
A mission without landing, but full of purpose
Unlike future Artemis missions, Artemis II will not attempt a lunar landing. Instead, it serves as a critical test flight designed to validate systems required for sustained human exploration beyond Earth orbit.NASA’s long-term roadmap includes landing astronauts on the Moon in later missions, with Artemis IV currently targeted for more advanced lunar operations later in the decade.
Why the April 6 flyby matters
The April 6 flyby represents more than just a visual spectacle — it is a demonstration of human capability in deep space navigation.The ability to send astronauts safely around the Moon and back is a foundational step toward more complex missions, including long-duration stays on the lunar surface and eventual journeys to Mars.
For the Artemis II crew, the moment they glimpse the Moon’s far side will symbolise both a scientific achievement and a continuation of humanity’s exploration legacy.
