NASA Launches Artemis II: The First Crewed Mission Around the Moon in over 50 Years

On April 1, 2026, NASA launched Artemis II: the first crewed mission around the Moon in over 50 years. The mission is a crucial step toward NASA's goal of once again setting foot on lunar soil, and eventually establishing a permanent lunar presence — including a moon base — with the help of international partners.

Belfer Center experts offer their analysis of why this mission is so significant in space-flight history.

6:17 pm, Banana Creek viewing area, Kennedy Space Center, on the 10 minute hold.

Today is the first time since 1972 that we have launched humans beyond low earth orbit.  The excitement at Banana Creek is palpable. The crowd is buzzing as we approach the terminal countdown.

The Artemis II crew won’t land on the moon this time, but they will prove out the systems that will make a return to the moon possible. Soon. That might sound anticlimactic, but it’s not. NASA is leading the return to the moon. This time not just to visit but to stay. And eventually send humans to Mars and beyond.

Space flight is hard.  The vehicles that take humans into space are the most complex and ambitious engineering achievements of humanity. The dream of exploration continues to push us to innovate and dare great things.

When the crew launch today they will be carrying the hopes and dreams of our nation with them. They will be carrying with them the work of tens of thousands of people across the country. They will be going farther than anyone has from the earth and paving the way for the next steps in our journey to the stars.

When Artemis II clears the tower today, four astronauts will travel farther from Earth than any human has in over fifty years. But the most consequential thing about this mission is not the distance. It is who is going and who is watching.

For the first time, a woman and a person of color will journey to the Moon. A Canadian astronaut flies alongside three Americans as a full mission crew member, not a passenger. These symbolic choices are a deliberate signal that the next era of space exploration belongs to a broader coalition of humanity than the last one did. More than fifty nations have signed the Artemis Accords, a U.S.-led framework for how the world will govern lunar activity, share scientific data, and manage resources beyond Earth’s atmosphere. Whether that coalition holds, deepens, and delivers will shape the geopolitics of space for the next century.

China intends to land on the Moon by 2030. The question Artemis II begins to answer is not whether America can beat that timeline; it is whether a free and open coalition of nations can build something more durable than a race. That is the architecture being tested today. And the whole world has reason to look up tonight, and feel what that future might look like.

Artemis 2 grants humanity the chance to marvel in ways we do too infrequently for our own good as a species.  

Our ability to travel beyond the biosphere that is the single source of our health and wealth should be recognized as the miracle that it is.   

My Grandmommy Ruth, the youngest of my grandparents, was born two weeks before the Wright brothers flew at Kitty Hawk.  In her lifetime she saw Neil Armstrong land on the moon and the Space Shuttle fly and fly again and again. She witnessed the first humans to travel around the moon on Apollo 8 in 1968 (58 years ago) — which was only seven years after the first human traveled to space.  Only four years later, the last humans travelled to the moon in 1972.  In one lifetime, we went from being grounded on earth to leaping onto the lunar surface. 

Apollo was a magnificent achievement in early exploration. Five decades may seem like a lot given current media cycles but it is a blink in human history. Apollo gave us our first perspective from outside the biosphere. Humanity first looked back and experienced the fundamental reality that all of human history bloomed on a blue glowing ball hanging within the lethal vacuum of space.  We are still, too slowly, coming to terms with this reality.

The Artemis 2 mission is an extraordinary return to an extraterrestrial universe hostile to our existence. Human health is not a universal “thing.” It is a bespoke solution to the particular environmental conditions of Earth that make our existence possible. As we leave the safety of our home planet, we still have a tremendous amount to learn about how to maintain health away from earth. Operationally, Artemis is testing hardware, life support systems and procedures, and working on important science and human health research.  It promises  a mission of historic firsts in its crew. 

But more importantly, it is a critical next step towards the goal of establishing long-term human habitations on the lunar surface. And that a step to be followed by others. Living creatures don’t limit their range.  Fungi thrive on the Antarctic ice.  Arctic terns travel the globe. Humans travel beyond it.

From a historic standpoint, the Apollo missions were as Magellan exploring the unknown portions of our globe — helping to establish the biologic and scientific realities of our existence through human exploration. 

The Artemis missions will be seen more in line with the early Jamestown settlement, as a new branch in history as we permanently expand the reach and interconnectedness of all living beings in ways that we in the present can hardly imagine and that the future will look back and imagine was inevitable.

“No man is an island” we learned in English class— nor is any crewed mission into space. Whatever our nationality, our hearts and dreams travel with the Artemis 2 crew and their very human mission.

If America’s return to the Moon succeeds—launched this week by Artemis II—then by the decade’s end there may never again be a time in history when human beings inhabit only one celestial body. We may become, forever, an interplanetary species. While the philosophical implications of that are breathtaking, the political impacts are also profound, as Artemis II may determine the future of Great Power conflict beyond Earth. 

We’ve mostly forgotten that when the Soviet Union first beat America to orbit, the nation’s diplomats and spymasters, at least in private, rejoiced. Sputnik established—even if inadvertently—a principle known as “freedom of the skies”. The USSR’s success meant that space was officially beyond national borders, allowing American reconnaissance of the Soviet Union without relying on risky (and technically illegal) spy planes. A decade later, when the Outer Space Treaty was signed in 1967, the main goal of America’s military was cementing  freedom of the skies as international law. That treaty, with Pentagon support, passed the Senate unanimously. 

Why does this matter for Artemis II? Because, just like the first Sputnik flight, the rules of the road for the global commons are being set, this time for the Moon.

America’s approach to lunar exploration is laid out in the Artemis Accords, a set of principles amongst the United States and its allies. The Artemis Accords include two key ideas that, like freedom of the skies half a century ago, are integral to American strategy in space: that resources can be extracted and used in situ; and that countries can establish “safety zones” to secure lunar activities such as mining. However, while these are necessities for a sustained human presence beyond Earth—especially for commercial activities that rely on private investment—both Russia and China have historically deemed them a violation of the Outer Space Treaty’s prohibition on “national appropriation” of celestial bodies.

This is the real significance of Artemis II. In international space governance, practice often determines law. What the United States and our partners do now — how we extract lunar resources, how we establish and enforce safety zones, and how Russia and China respond — will harden into the norms that govern human activity beyond Earth for generations. And perhaps that’s almost as exciting as the launch itself.
