Artemis II Launched Yesterday. Tonight, They’re Going to the Moon.

When we wrote about Artemis II eight days ago, it was still a countdown. Four astronauts waiting in Florida, a rocket ready on Pad 39B, a launch window that had already slipped once. We said here’s what you need to know.

Now they’re up there. Tonight, they leave Earth behind for good.

NASA’s SLS rocket lifted off from Kennedy Space Center on April 1st at 6:35 p.m. Eastern, carrying Reid Wiseman, Victor Glover, Christina Koch, and Canada’s Jeremy Hansen into orbit aboard the Orion spacecraft, which the crew named Integrity. It was the first crewed flight beyond low Earth orbit since Apollo 17 in December 1972, over 53 years ago. If you felt like something shifted in the world this week, you were not imagining it.

What Just Happened, Exactly

The launch went clean. About 49 minutes after liftoff, the SLS upper stage fired to place Orion into an elliptical orbit around Earth. A second burn raised the spacecraft’s apogee to roughly 43,730 miles above our planet, while the crew immediately began running through checklists: life support systems, communications, navigation, manual spacecraft control tests. The crew is not passengers. They are test pilots putting a new vehicle through its paces.

Four CubeSats were also deployed from the rocket’s upper stage, carrying experiments from Argentina, Germany, South Korea, and Saudi Arabia. Nobody talks much about the CubeSats, but it’s genuinely wild that a human Moon mission doubled as a global science launch platform.

And yes, there was apparently a toilet situation. Space.com’s live blog mentioned “toilet trouble” without elaborating. Probably fine. Probably.

Tonight’s Burn Is the Point of No Return

As of this writing, the Artemis II mission management team is preparing to decide whether to go ahead with the Trans-Lunar Injection (TLI) burn, scheduled for 7:49:50 p.m. Eastern on April 2nd. That’s tonight.

The TLI burn is a six-minute firing of the Orbital Maneuvering System engine on Orion’s service module, generating around 6,000 pounds of thrust. To put that in context: enough to accelerate a car from zero to 60 mph in 2.7 seconds. Applied to a spacecraft already moving at tens of thousands of miles per hour, it commits Integrity to a free-return trajectory that arcs around the far side of the Moon and uses lunar gravity to slingshot the crew back to Earth.

Free-return is the key safety feature. Even if something fails after the TLI burn, Orion will come home. The trajectory is designed that way. It’s what Apollo 13 famously used after the oxygen tank explosion in 1970. The physics handles it. You just have to execute the burn correctly.

After the burn, it’s roughly 685,000 miles total, ten days round trip.

The Records Being Set Right Now

This mission is stacked with firsts:

• Victor Glover is the first Black astronaut to travel beyond low Earth orbit in history. He’s also the pilot of Orion, flying the vehicle manually during orbital test maneuvers.
• Christina Koch is the first woman to travel to lunar distance. She already holds the record for the longest single spaceflight by a woman (328 days on the ISS, 2019-2020).
• Jeremy Hansen is the first non-American to fly around the Moon. He’s a Canadian Space Agency astronaut who’s never been to space before. His first mission is a lunar flyby. Not bad for a debut.
• The flyby will take Integrity to approximately 10,300 kilometers from the lunar surface, setting a new record for the farthest distance any human crew has traveled from Earth. The previous record was set by Apollo 13 in 1970.

There’s also an 8-year-old named Lucas Ye whose plush toy design, a white moon mascot called Rise, is on board the spacecraft. Lucas was invited to watch the launch at Kennedy Space Center. The toy will go farther from Earth than any stuffed animal in history. This is the kind of detail that should be in every article about this mission and somehow always ends up buried at the bottom.

Why This Matters More Than It Seems

Artemis II is technically a test flight. NASA will tell you that repeatedly. It’s not a landing. Nobody is setting foot on the Moon. From a headline perspective, there’s nothing here as visually dramatic as Buzz Aldrin’s bootprint or the Apollo 11 flag planting.

But that’s kind of the point.

The last time humans went to the Moon, Apollo 17’s Gene Cernan stepped off the lunar surface in December 1972 and said “we shall return.” Then we didn’t, for over half a century. Multiple programs were started and cancelled. The Constellation program, the Space Launch System’s predecessor, was years behind schedule and billions over budget before it ever flew. Artemis I, an uncrewed test in 2022, worked. Now Artemis II is flying with people.

The Artemis program is designed to be different from Apollo in one crucial way: it’s not supposed to end. The plan is Artemis III landing at the lunar south pole (currently targeted for 2027, though schedules in space are flexible), followed by Artemis IV, then a permanent Gateway space station in lunar orbit, and eventually a base camp on the surface. Whether all of that actually happens is anyone’s guess, but the infrastructure for sustained human presence on the Moon is being built right now, and it’s currently riding a free-return trajectory at thousands of miles per hour.

The Moon also has water ice in its permanently shadowed craters. That ice can be split into hydrogen and oxygen, which happen to be rocket propellant. A Moon base with access to water ice is, theoretically, a refueling depot for missions to Mars. The whole thing is a stepping stone, not an endpoint. (Speaking of things we thought were gone for good, Mega Man Star Force just came back after 18 years. Sometimes waiting pays off.)

What Happens Next

Assuming the TLI burn goes as planned tonight:

• Day 3-4: Orion passes behind the Moon. Communications blackout. This is the part that makes flight controllers go quiet for a few minutes.
• Day 4-5: Closest approach to the lunar surface, around 10,300 km. Earth will look like a blue marble from there, roughly the size of a thumbnail held at arm’s length. The crew will have windows.
• Day 6-10: The long coast home. Plenty of time for system tests, sleep schedules, and presumably sorting out the toilet situation.
• Day 10: Reentry at approximately 40,000 km/h (25,000 mph). Splashdown in the Pacific Ocean off the coast of San Diego. Recovery by the USS San Diego.

If all of that goes cleanly, Artemis III starts its countdown. Humans back on the lunar surface for the first time since 1972. Maybe 2027. Maybe 2028. But the door is open again.

A Note on Perspective

We covered the fireball surge of early 2026 a few days ago. Rocks falling from the sky with unusual frequency, nobody sure exactly why. And now, while all that was happening, four people were getting ready to launch to the Moon.

There are four people sitting in a capsule right now, orbiting Earth at about 17,500 mph, waiting to find out if tonight’s burn is a go. They named their spacecraft Integrity. In a few hours, they will either commit to the Moon or stay in high Earth orbit, depending on what the data says.

The data is going to say go.

Fifty-three years is long enough to wait. The Moon isn’t going anywhere. But we should have gone back sooner, and the fact that we’re finally doing it, with a crew that looks like all of humanity and not just one corner of it, matters more than any benchmark or milestone could capture.

Go, Integrity.
