What the Artemis II Mission Has Taught Us about Future Crewed Missions to the Moon ⋆ The Costa Rica News
What Artemis II has taught us so far?
Just a few days after NASA’s Space Launch System (SLS) arrived at the launch pad at Kennedy Space Center, the most important lesson about Artemis II had already been learned.
Following two canceled launches in February and March due to various technical issues, NASA Administrator Jared Isaacman stated: “Launching a rocket as important and complex as the SLS every three years is not the path to success.”
The previous uncrewed Artemis I mission launched in November 2022.
The agency, he said, needed to stop treating each rocket “like a work of art” and conduct launches with the frequency expected of a serious program.
In effect, it was a declaration that we needed to stop repeating the same lessons every three years.
That matters, because it reframes everything that has come since. And, in light of that ambition, what has the mission shown us in the six days since Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen took off on April 1?
In short, far more than even the most optimistic dared to hope for.
A rocket that did its job
By every metric that matters to engineers, the SLS performed as planned. Every phase of the ascent was, in the formal language of mission control, “nominal”: maximum dynamic pressure, main engine shutdown, and booster separation.

Two of the three planned course corrections on the route to the Moon were canceled because the trajectory was already so precise that they weren’t necessary. As Simeon Barber, a space scientist at the Open University in the UK, said: “You have to give them credit—they got it right the first time.” The day after launch, the crucial moment arrived. Orion fired its main engine for five minutes and fifty-five seconds—a maneuver known as the trans-lunar injection—placing the spacecraft on a circular trajectory toward the Moon without the need for any significant additional maneuvers.
According to Lori Glaze, director of the Artemis program, the powerful engine burn was “flawless.”
Crew members aboard the spacecraft
The official objective of this mission was to put people in Orion and find out what happens—not only with the spacecraft itself, but also with the interaction between the crew and the machine.
What has happened is exactly what was expected and exactly what could not have been learned in a simulator.
There have been issues with the bathroom, and a problem with the water dispenser forced the crew to store water in bags as a precaution. An initial press conference mentioned a minor loss of redundancy in one of the helium systems, but this was quietly resolved.
As Barber noted: “It’s about integrating humans into the process—those humans who press buttons, breathe carbon dioxide, want air conditioning, and use the bathroom. It was all about how the system works with them on board.”
The engineers who are monitoring Orion’s CO2 removal system through consecutive test sessions, or who are evaluating the spacecraft’s behavior with the thrusters deliberately deactivated, are demonstrating that this vehicle is safe enough to transport people to the lunar surface.
Barber’s overall assessment was straightforward: “Orion seems to have performed quite well, to be honest; especially the propulsion system, which is what really matters.”
Real science or NASA hype?
NASA has praised the scientific findings. The crew conducted extensive observations during their flyby: they recorded in real time some 35 geological formations, color variations that could reveal the mineral composition, and a solar eclipse from deep space that, according to pilot Victor Glover, “seemed unreal.”
One image stood out: the Orientale Basin, a 965-kilometer crater near the far side of the Moon, seen in its entirety for the first time by human eyes.
However, science is not the main focus. Professor Chris Lintott of Oxford, co-host of the TV program The Sky at Night, was blunt: “The artistic value of the images sent by Artemis and its crew is significant, but their scientific value is limited.”
The Indian probe Chandrayaan-3 landed near the South Pole in 2023. Meanwhile, the Chinese probe Chang’e-6 retrieved samples from the far side in 2024. These robotic instruments have mapped this terrain in extraordinary detail.
But the most emotional moment didn’t come from any instrument, but from the crew. As the astronauts broke the distance record set by the Apollo 13 crew in 1970, mission specialist Jeremy Hansen contacted Mission Control in Houston.
There was a crater, he said, on the boundary between the near side and the far side: a bright spot northwest of the Glushko crater.
“We’ve lost a loved one,” he said, his voice breaking. “Her name was Carroll, Reid’s wife, Katie and Ellie’s mother. And we’d like to name [the crater] Carroll.” Forty-five seconds of silence followed. Commander Reid Wiseman wept. The crew embraced. Back on Earth, his daughters watched from Houston.
That moment matters for reasons that go beyond sentimentality.
Space programs that fail to generate genuine, spontaneous human emotion do not endure. The reason the Apollo program endures in the collective memory is not just its engineering; it is what it represented about humanity’s reach and courage.
Artemis II, in that moment, conveyed that same message.
The biggest test is yet to come
The mission isn’t over yet. Orion is heading home and is scheduled to splash down in the Pacific Ocean near San Diego, U.S., on April 11.
What remains is reentry into Earth’s atmosphere—the moment that caused so much anxiety after Artemis I, when unexpected damage to the heat shield triggered an investigation that delayed this mission by more than a year. The Orion capsule will enter the atmosphere at about 40,000 km/h.
This is the test that no simulator can replicate, and its outcome will define the legacy of this mission more than any image of the far side of the Moon.
If reentry goes smoothly, the outlook for Artemis II will be truly encouraging. The rocket worked. The spacecraft worked. The crew operated the systems with competence and skill. And NASA has finally put together a credible plan to build on this momentum rather than wait three years and start over.
A moon landing by 2028 remains an ambitious goal. Barber estimates that we’re still three to four years away, and it’s hard to argue with that assessment.
But the smooth progress of this mission—from launch to the lunar flyby—has shifted the odds. The question is no longer whether Orion can fly, but whether the landers and the political will can keep up.
The spacecraft, at least, has done its part.
Artemis II is a story of inspiration and science. Recent events evoked the Apollo program. At a time when the world lacks optimism—just as in the 1960s, with wars around the globe and civil unrest in the United States—this was a moment when, for one night, we were able to remember that we are one. We can see that image of Earth.
This is not the end of the story, far from it; it is merely a test flight for an eventual moon landing—not just one, but many more to come.
