NASA's first crewed mission venturing around the Moon since the Apollo era is rapidly approaching launch. This flight, designated Artemis II, follows the successful uncrewed Artemis I test flight in 2022, which utilized the Space Launch System (SLS) rocket and the Orion spacecraft.

Mission Preparations and Technical Milestones

Engineers are currently focused on critical pre-launch activities. This includes powering up essential flight hardware and rigorously checking all communication links.

Preparations also involve readying the rocket’s cryogenic systems for the complex fueling sequence. This process requires loading hundreds of thousands of gallons of super-cooled liquid hydrogen and liquid oxygen.

Meet the Artemis II Crew

The Artemis II mission features a crew of four astronauts, supported by two backup crew members. The crew recently posed in front of the massive Space Launch System rocket on January 17, 2026.

For these astronauts, the countdown represents more than just the time until liftoff. They are preparing for a journey that will mark a significant milestone in space exploration history.

Canadian Astronaut Makes History

One of the mission specialists set to fly is Canadian astronaut Jeremy Hansen. He is slated to become the first Canadian to travel to the Moon.

Artemis II will be Hansen’s inaugural spaceflight. Born in London, Ontario, Hansen joined the 614 Royal Canadian Air Cadet Squadron at age 12. He completed his astronaut candidate training in 2011 and is married with three children.

Commander Reid Wiseman’s Extensive Background

NASA astronaut Reid Wiseman will command the Artemis II mission. He brings a wealth of experience from both aviation and previous spaceflight to this historic lunar flyby.

Wiseman, a 27-year Navy veteran, was selected as a NASA astronaut in 2009. He previously flew aboard the International Space Station (ISS) as part of Expedition 41 in 2014.

During his time on the ISS, Wiseman and his colleagues conducted over 300 science experiments covering human physiology and astrophysics. His aviation background includes flying the F-14 Tomcat and FA-18F Super Hornet, as well as test pilot work on the F-35 Lightning II.

The Artemis II Lunar Trajectory

Artemis II will send humans around the Moon for the first time since 1972. However, the mission profile differs from some Apollo flights.

Instead of entering lunar orbit or flying close to the surface, the Orion spacecraft will perform a flyby. According to NASA, the spacecraft will pass the Moon at a specific distance, giving the crew an expansive view.

This higher path is designed to offer the astronauts a broader perspective of the lunar surface, including the north and south poles, which are vital areas for future exploration.

Visualizing the Flyby

NASA noted that at its closest approach, the Moon will appear to the Artemis II crew similarly in size to “a basketball held at arm’s length.”

Following this lunar pass, the Orion spacecraft will immediately begin its trajectory back toward Earth. The four astronauts are scheduled to splash down in the Pacific Ocean, approximately 50 miles off the coast of San Diego.

Launch Window Considerations

Forecasters have indicated an 80% probability of favorable weather conditions for the launch attempt. The primary weather concerns that could cause a delay involve clouds and strong winds.

If the initial launch attempt is postponed, forecasters caution that subsequent launch opportunities might also face interference from adverse weather conditions.
