NASA is gearing up for a historic journey back to the Moon. If everything goes according to plan, the Artemis II mission will launch in February 2026, marking the first time humans have traveled beyond low Earth orbit since the Apollo era. This isn’t a Moon landing mission—astronauts won’t set foot on the lunar surface—but it will take them on a daring journey around the Moon, farther from Earth than any human has ever gone before.
Here are eight important things you need to know about this exciting mission.
Artemis II Astronauts to See the Moon’s Hidden Side
The Moon always shows the same face to Earth because it is tidally locked. That means there’s a far side of the Moon that most people—and even most astronauts—have never seen. The Artemis II crew will become part of a very small group to witness this hidden side firsthand.
The mission will carry four astronauts: Commander Reid Wiseman, Pilot Victor Glover, Mission Specialist Christina Koch, and Canadian Mission Specialist Jeremy Hansen. This group includes the first woman to fly around the Moon, the first person of color on a lunar mission, and the first non-American astronaut to travel this far into space.

The Orion spacecraft will carry high-quality cameras, including Nikon D5 models, to capture stunning images. From breathtaking shots of the Earth from deep space to views of the lunar far side never seen before, the mission promises a visual spectacle. Fans of space exploration will also get a glimpse of the astronauts’ daily lives as they work and live in the cramped quarters of their spacecraft.
Cutting-Edge Technology Tested in Space
Artemis II isn’t just about sightseeing—it’s a crucial test of new space technologies. The Orion spacecraft is equipped with the Orion Artemis II Optical Communications System, which uses infrared lasers instead of traditional radio waves to send data. This system can transmit images, live video, and science data at much higher speeds than ever before.
However, there’s a catch. The laser system requires a clear line of sight to Earth. During the mission, there will be a planned “loss of signal” period of about 45 minutes when the spacecraft is out of contact with Mission Control. This means the astronauts will temporarily experience a communications blackout—a reminder of how far they are from home.

The spacecraft will also use a “lunar free-return trajectory.” This means it will slingshot around the Moon using the Moon’s gravity to guide it back to Earth. This clever path ensures that even if the engines fail, the crew can safely return home. Small engine burns may still be needed for fine-tuning, but the design offers a safety margin that previous missions didn’t have.
Orion’s heat shield will also be tested during re-entry, protecting astronauts from temperatures reaching over 2,700°C (4,890°F) as they return to Earth at speeds of around 40,000 km/h. The ablative shield works by slowly burning away and carrying heat off the spacecraft—similar to how sweat cools the human body.
A Journey into Deep Space Like No Other
Artemis II will carry humans farther into space than any mission in over 50 years. The spacecraft is expected to travel about 400 million kilometers (250 million miles) from Earth, surpassing the Apollo 13 record of 248 million miles. This journey will give astronauts an unprecedented view of deep space while testing life-support systems, radiation shielding, and human endurance needed for future long-term missions.
The four crew members will follow strict daily routines, monitoring spacecraft systems, performing navigation checks, and practicing crucial maneuvers. Scheduled times for sleeping, meals, and exercise will keep the astronauts healthy and alert during the mission.
Artemis II also serves as a “dress rehearsal” for Artemis III, NASA’s next Moon mission aiming for the lunar south pole. The mission will help refine technologies, communications, and emergency procedures ahead of humans landing on the Moon for the first time since 1972.
How Will Astronauts Survive in Space Until 2025?
The spacecraft will launch aboard NASA’s Space Launch System, a modular rocket using engines recycled from the Space Shuttle. Combining modern safety features with raw power, the SLS represents NASA’s most advanced launch vehicle to date.
From exploring the Moon’s hidden far side to testing new technologies, Artemis II promises a historic journey that pushes the boundaries of human space exploration.
