Artemis II: NASA’s Historic Crewed Lunar Flyby Reaches Critical Phase
Humanity is returning to the vicinity of the Moon for the first time in over 50 years. The Artemis II mission, NASA’s first crewed flight of the Orion spacecraft and Space Launch System (SLS) rocket, is currently executing a 10-day journey that serves as a vital bridge to future lunar landings and eventual missions to Mars.
- Mission Goal: A 10-day crewed lunar flyby to test deep space systems.
- Launch Date: April 1, 2026, from the Kennedy Space Center in Florida.
- The Crew: Four astronauts, including three Americans and one Canadian.
- Major Milestone: A lunar flyby on April 6, 2026, providing a view of the Moon’s far side.
The Journey to the Far Side of the Moon
On Monday, April 6, 2026, the Artemis II crew is scheduled to reach the most anticipated phase of their mission: the lunar flyby. This event occurs within a roughly six-hour window where the sun, Moon, and Orion spacecraft align perfectly. This specific alignment allows the crew to view the far side of the Moon, a region that remains invisible from Earth [USA Today].
To ensure they hit this pinpoint trajectory, the crew completed a critical correction burn on April 5. This maneuver put the spacecraft on the exact flight path required for the flyby. As of early April 5, the Orion spacecraft was traveling at approximately 1,771 mph, situated about 206,482 miles from Earth and roughly 75,000 miles from the Moon [USA Today].
Meet the Artemis II Crew
The mission is powered by a diverse, international crew of four astronauts who are testing the limits of human deep space capabilities. The team consists of:
- Reid Wiseman (NASA)
- Victor Glover (NASA)
- Christina Hammock Koch (NASA)
- Jeremy Hansen (Canadian Space Agency)
Since lifting off at 6:35 p.m. ET on April 1 [The New York Times], the crew has been conducting a series of essential tests. These include manual piloting demonstrations and practicing the donning and removal of space suits while in orbit [ABC News].
The Technology Powering the Mission
Artemis II relies on two primary pieces of hardware designed for deep space exploration:
The Space Launch System (SLS)
The SLS is NASA’s new heavy-lift rocket, designed to provide the thrust necessary to send the Orion spacecraft and its crew out of Earth’s orbit and toward the Moon [NASA].
The Orion Spacecraft
Orion serves as the exploration vehicle that sustains the crew during their 685,000-mile journey. It’s built to protect astronauts from the harsh environment of deep space and ensure their safe return to Earth [NASA].
What Happens Next?
While Artemis II is a flyby mission and will not land on the lunar surface, it’s a critical stepping stone. The data gathered from these 10 days of flight will pave the way for future missions. NASA plans for astronauts to eventually set foot on the Moon again, with a landing planned for Artemis IV in 2028 [USA Today].
The ultimate goal of the Artemis program is the establishment of a permanent lunar base, which will serve as a testing ground for the technology and human endurance needed for the first crewed missions to Mars [ABC News].
Frequently Asked Questions
Is Artemis II landing on the Moon?
No. Artemis II is a crewed lunar flyby. The mission is designed to test systems and orbit the Moon without landing. A lunar landing is planned for Artemis IV in 2028 [USA Today].
How long is the Artemis II mission?
The mission is a 10-day journey [NASA].
Why is the “far side” of the Moon critical?
The far side of the Moon cannot be seen from Earth. The Artemis II flyby allows the crew to observe this region, providing a unique perspective and testing the spacecraft’s ability to operate at record-breaking distances from Earth [USA Today].
