NASA’s Artemis II: Why Return to the Moon Now?

The Artemis II mission, scheduled to launch on April 1, 2026, will send four astronauts on a lunar flyby, marking the first crewed mission beyond low Earth orbit since Apollo 17 in 1972.

The ten-day mission will carry NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, along with Canadian Space Agency astronaut Jeremy Hansen, on a trajectory around the Moon and back to Earth aboard the Orion spacecraft, propelled by the Space Launch System (SLS) rocket. The launch is slated to originate from Kennedy Space Center’s Launch Complex 39B in Cape Canaveral, Florida.

While the Apollo missions of the 1960s and 70s saw six successful lunar landings, the current impetus for returning to the Moon extends beyond national prestige. A key driver is the potential for resource extraction. The lunar surface contains valuable elements, including rare earth minerals, iron, titanium, and helium, according to planetary scientists. Perhaps most significantly, water ice has been detected in permanently shadowed craters at the lunar poles.

“The Moon contains the same elements that we have here on Earth,” explains Professor Sara Russell, a planetary scientist at the Natural History Museum in London. “There could be areas of the Moon where these are concentrated enough to be economically viable to extract.” This water ice, in particular, is crucial, as it can be broken down into oxygen for breathable air and hydrogen for rocket fuel, potentially establishing a sustainable presence on the lunar surface.

The renewed interest in lunar exploration is also fueled by geopolitical competition, particularly with China. China successfully landed a robotic spacecraft on the Moon in 2020 and has stated its intention to send humans there by 2030. This has intensified the race to secure access to strategically important lunar resources and establish a foothold in space.

The 1967 Outer Space Treaty prohibits nations from claiming sovereignty over celestial bodies. However, the question of resource rights remains complex. Libby Jackson, director of the Space Department at the Science Museum in London, notes that while no country can own lunar territory, they can operate on it without interference. “So the important thing right now is trying to get a piece of land. You can’t own it, but you can leverage it. And once you’re there, you have it for as long as you want,” she said.

Beyond resource acquisition, Artemis II is viewed as a critical stepping stone towards NASA’s ultimate goal: Mars. The lunar mission will serve as a testing ground for technologies and procedures necessary for long-duration spaceflight, including life support systems, radiation shielding, and in-situ resource utilization. Testing these systems on the Moon is considered safer and more cost-effective than attempting them directly on Mars.

“Going to the Moon and staying there for a prolonged period is much safer, much cheaper, and much easier as a testbed for learning how to live and work on another planet,” Jackson stated.

The Artemis II mission also offers a unique opportunity to further scientific understanding of the Moon’s history and its relationship to Earth. Rocks brought back by the Apollo missions revealed that the Moon formed from debris ejected after a Mars-sized object collided with Earth billions of years ago. Further lunar samples could provide even more insights into the early solar system.

“The Moon is a fantastic archive of the Earth,” Russell explained. “A new batch of rocks from a different area of the Moon would be incredible.”

The mission is expected to inspire a new generation of scientists, engineers, and mathematicians, mirroring the impact of the Apollo program. The high-resolution imagery and live coverage of Artemis II are intended to capture the public’s imagination and encourage interest in STEM fields.

The Artemis II crew is scheduled to be recovered by the U.S. Navy in the Pacific Ocean approximately ten days after launch, with a planned landing date of April 10, 2026. The mission will achieve a maximum distance of approximately 4,700 miles (7,600 km) beyond the Moon and an atmospheric reentry speed of around 25,000 miles per hour (40,000 km/h).
