For the First Time in 50 Years, Humans Are Heading Back to the Moon

The last time a human being looked out a window and saw the Moon up close, bell-bottoms were in style and the internet didn’t exist. That was 1972. Now, for the first time in half a century, astronauts are making the trip again — and this time, they’re going somewhere no human eye has ever seen.

NASA’s Artemis II mission has launched, and it’s carrying a crew of astronauts on a path that will swing them around the far side of the Moon. Not just close to it. Around it. To the side that permanently faces away from Earth — the side we have never, ever seen with our own eyes.

Why Haven’t We Done This Already?

Fair question. We landed on the Moon six times between 1969 and 1972. Why did it take another 50-plus years to go back?

The short answer: it’s expensive, dangerous, and complicated. After the Apollo program ended, space agencies shifted focus to things closer to home — like the International Space Station, which orbits Earth at roughly the same distance as flying from New York to Los Angeles (about 400 kilometers up). The Moon, by comparison, is about 1,000 times farther away. That extra distance changes everything.

Then there’s the matter of why you go. Apollo was a race — a geopolitical sprint fueled by Cold War competition with the Soviet Union. Once the U.S. “won,” the urgency faded. But now there are new reasons to return. Scientists want to study water ice hiding in permanently shadowed craters near the Moon’s south pole. Engineers want to test whether humans can live and work in deep space for extended periods. And NASA’s long-term goal is even more ambitious: use the Moon as a stepping stone to eventually send humans to Mars.

Artemis II is the crucial next step in that plan. Think of it like a dress rehearsal before the main show.

What Artemis II Is Actually Doing

Let’s be clear about what this mission is and isn’t. Artemis II is not a landing. The crew won’t touch down on the lunar surface — that’s planned for a later mission. Instead, this is a fly-by. The spacecraft will loop around the Moon in a carefully calculated path, bringing the astronauts closer to the lunar surface than any human has been since Apollo 17 in December 1972.

But here’s the part that makes this mission historically unique: the trajectory takes the crew around the far side of the Moon.

The Moon is “tidally locked” to Earth, which is a fancy way of saying it spins at exactly the right speed so that the same face always points toward us. Think of it like a dancer who always keeps their eyes on one spot in the audience — no matter how many times they spin, you only ever see their front.

The result? From Earth, we always see the same side of the Moon. The other side — the “far side” — is permanently hidden from our view. Telescopes can’t help. Satellites have photographed it, sure. But no human being has ever floated in space and looked at it directly with their own eyes.

Until now.

The Artemis II crew will become the first humans in history to see the lunar far side in person. As the spacecraft swings around the Moon, they’ll lose radio contact with Earth — because the Moon itself will be blocking the signal. For a brief period, they’ll be completely cut off. No communication. Just four humans, a spacecraft, and the silence of deep space on the other side of the Moon.

Why the Far Side Matters

You might be thinking: okay, it’s the back of the Moon. So what?

Actually, the far side is fascinating for a bunch of reasons. It’s geologically different from the near side — more heavily cratered, with fewer of the dark volcanic plains (called “maria,” Latin for seas) that give the near side its familiar face. Scientists aren’t entirely sure why, and getting humans closer to it is part of figuring that out.

There’s also a practical reason to care about the far side: it’s radio-quiet. Earth constantly radiates radio waves — from our phones, TVs, satellites, and Wi-Fi. All that electromagnetic noise makes it hard for radio telescopes to pick up faint signals from the universe. But the far side of the Moon? It’s shielded from all of that by the Moon itself. It’s the quietest spot in the inner solar system. Future telescopes placed there could potentially detect signals from the very early universe that we simply cannot hear from Earth.

In other words, the far side of the Moon might be the best place in the neighborhood to listen for whispers from the beginning of time.

What This Means for the Future

Artemis II isn’t just about this one flight. It’s about proving that humans can safely travel deep into space again — and building the systems, knowledge, and confidence to go farther.

Every hour the crew spends in deep space teaches engineers something. How does the human body respond to radiation so far from Earth’s protective magnetic field? How do the life support systems hold up? How do astronauts handle the psychological weight of being genuinely far from home, with a communication delay and no quick return option?

These aren’t abstract questions. They’re exactly the questions NASA needs to answer before it can think seriously about a nine-month journey to Mars.

Think of Artemis II like the Wright Brothers’ second flight at Kitty Hawk — not the famous first one everyone knows about, but the next one, where they actually started figuring out how to make it reliable.

What Comes Next

If Artemis II goes well, the missions that follow will push even further. Artemis III plans to actually land astronauts on the lunar surface — including, for the first time ever, a woman and a person of color. A small space station called the Gateway is being built to orbit the Moon and serve as a base of operations. Eventually, NASA hopes to establish a long-term human presence on and around the Moon.

And beyond that? Mars. Maybe in the 2030s or 2040s. Maybe later. But for the first time in decades, that goal feels less like science fiction and more like a project under construction.

For now, though, four astronauts are hurtling through space at tens of thousands of kilometers per hour, preparing to witness something no human being has ever seen. They’ll peer out their windows at a landscape that has existed for 4.5 billion years — ancient, cratered, utterly silent — and they’ll be the first of our species to see it face to face.

Somewhere in the universe, that feels like it matters.
