On April 1, 2026, at 6:35 p.m. Eastern Daylight Time, the ground shook at Kennedy Space Center in Florida. A 322-foot-tall orange-and-white rocket called the Space Launch System lit up the evening sky and thundered upward. Inside the Orion spacecraft perched at its tip were four astronauts — the first humans to travel to the vicinity of the Moon since the Apollo 17 mission in December 1972.
NASA's Artemis II mission is now underway. And for those of us watching from Earth, it is one of the most significant launches in living memory.
What Exactly Is Artemis II?
The Artemis programme is NASA's ambitious effort to return humans to the Moon — and eventually go beyond it, to Mars. Artemis I, completed in December 2022, was an uncrewed test flight that sent the Orion spacecraft on a loop around the Moon and back, travelling more than 2.3 million kilometres without a single human on board.
Artemis II is the next step. It is the first crewed mission under the Artemis programme, and it sends four astronauts on an approximately 10-day journey around the Moon and back to Earth. It is not a landing mission — the astronauts will fly close to the Moon, around it, and return home. But make no mistake about how historic this is: no human being has travelled this far from Earth since the final Apollo mission over half a century ago.
The mission's stated goals are to test the Orion spacecraft's life support systems for the first time with actual people on board, assess critical hardware in the deep space environment, and lay the groundwork for everything that comes after — including the eventual crewed Moon landings planned from Artemis IV onward, targeted for 2028.
The Crew: Four People Carrying Humanity Forward
The Artemis II crew is composed of four astronauts, each chosen for both their expertise and their ability to represent the kind of future NASA is building.
Commander Reid Wiseman is a US Navy test pilot and NASA veteran who previously served as Commander of the International Space Station. He leads the mission and is responsible for crew safety and overall mission execution.
Pilot Victor Glover is a US Navy pilot and the first Black astronaut to fly on a long-duration mission to the ISS. His selection for Artemis II makes him the first Black astronaut to travel to the lunar vicinity — a milestone that extends the legacy of human space exploration in a meaningful direction.
Mission Specialist Christina Koch holds the record for the longest single spaceflight by a woman. She is the first woman to travel to the Moon since the Apollo era ended. If Artemis III or a later mission carries a woman to the lunar surface, Koch's flight with Artemis II is the chapter that made it possible.
Mission Specialist Jeremy Hansen is a Canadian Space Agency astronaut and the first Canadian to travel beyond Earth orbit. His presence makes Artemis II an international mission in the truest sense — a reminder that humanity's journey outward belongs to more than one nation.
Together, they lifted off to the sound of cheers erupting throughout Mission Control at Kennedy Space Center, carrying with them the dreams of millions of people across the planet.
What Happens During the 10-Day Mission?
The Artemis II mission is not a leisurely trip. From the moment of liftoff, every hour has a purpose.
In the first hours after launch, Victor Glover took manual control of the Orion spacecraft after it separated from the rocket's upper stage. He then piloted Orion through a series of proximity operations — manoeuvres designed to test the spacecraft's propulsion systems and its ability to operate close to another object in space. These tests matter because future missions will require Orion to dock with a lunar lander in deep space. Getting this right is not optional.
The crew has also begun testing Orion's life support systems, which is one of the most critical objectives of this flight. Everything from air circulation to waste management to the exercise flywheel — a cable-based device that lets astronauts do rowing, squats, and deadlifts in zero gravity — is being evaluated with real human beings aboard for the first time.
The lunar flyby itself is scheduled for Monday, April 6. During this phase, the crew will travel closer to the Moon's surface than any humans since the Apollo era. They will take photographs and record observations of the Moon's surface, including regions of the far side that have never been seen up close by human eyes. The shadowing conditions during the flyby are expected to create dramatic images, with sunlight stretching shadows across crater rims and ridges in a way that reveals the Moon's texture at a level of detail rarely captured.
There is also a 45-minute communications blackout planned during the deepest part of the lunar flyby, as the spacecraft travels behind the far side of the Moon and loses line-of-sight contact with Earth. The crew will be entirely on their own during this window — a detail that captures something profound about just how far from home they are.
Following the flyby, the astronauts will return to Earth and splash down in the Pacific Ocean, with US Navy personnel and recovery teams standing by.
The Science Riding Along
Artemis II is carrying more than four astronauts. It is carrying science.
One of the most intriguing payloads is AVATAR — which stands for A Virtual Astronaut Tissue Analog Response. This technology uses organ-on-a-chip devices, essentially miniaturised replicas of human organs, to study how increased radiation and microgravity affect human biology. AVATAR is being tested beyond Earth's protective Van Allen Belt for the first time on this mission, producing data that will be essential for keeping future crews healthy on long-duration missions to the Moon, and eventually to Mars.
A second payload, ARCHAR (Artemis Research for Crew Health And Readiness), will also monitor crew health throughout the mission, adding to what NASA knows about how the human body responds to deep space conditions.
The mission even carries a small piece of cultural tradition. The crew's zero-gravity indicator — an object that floats freely in the cabin once in space and lets viewers on the ground know the spacecraft is in microgravity — was designed through a global competition that received over 2,600 entries from more than 50 countries. The winning design, called Rise, is now floating inside Orion as it heads toward the Moon.
Why This Matters Beyond America
It is easy to look at Artemis II as an American achievement. But the fuller picture is more interesting. Canada has sent an astronaut to the Moon's vicinity for the first time in history. The science aboard the spacecraft will benefit all of humanity. The live coverage is reaching audiences in every corner of the world. India, which has its own active lunar programme — including the successful Chandrayaan-3 mission in 2023, which landed near the Moon's south pole — has particular reason to watch Artemis II closely.
What NASA learns from Artemis II about life support, human health in deep space, and spacecraft operations near the Moon is information that every space agency in the world will eventually draw on. The era of lunar exploration that Artemis is reopening is not a repeat of the 1960s race to be first. It is something different — a sustained effort to understand and eventually inhabit Earth's nearest neighbour, and to use that experience as a stepping stone to the wider solar system.
Artemis III is already in planning, targeted to carry astronauts into close orbit around Earth to practise rendezvous with lunar landing hardware. Artemis IV, planned for 2028, is now the programme's first targeted lunar surface landing.
The Moon is being taken seriously again. And Artemis II is the mission that made it real.
Right Now, in Space
As this article goes live, the four crew members of Artemis II are orbiting Earth, completing their engine burns, checking their systems, and preparing for the long journey ahead. Victor Glover has piloted the spacecraft through its proximity operations. The solar array wings have fully deployed, giving Orion a wingspan of roughly 63 feet. The crew signed the inside of the White Room — the access corridor to the spacecraft — before boarding, continuing a NASA tradition that stretches back to the Gemini programme of the 1960s.
They said goodnight to Mission Control after their first day in space and are resting now, preparing for what comes next.
In a few days, they will be the first people to see the Moon's far side with their own eyes since 1972. Whatever else happens in the news cycle, that fact deserves a moment of quiet appreciation.
