In a landmark moment for human spaceflight, NASA launched a four-person crew toward the Moon on Wednesday, marking the first crewed lunar mission since the end of the Apollo program more than five decades ago. Riding atop the most powerful operational rocket ever built, the astronauts embarked on a trailblazing journey designed to lay the groundwork for future lunar landings and the construction of a long-term American presence on the Moon.
The mission, known as Artemis II, is commanded by Reid Wiseman and includes Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen. The crew is expected to travel farther from Earth than any astronauts since 1972, pushing the boundaries of human exploration.

Unlike the Apollo missions, Artemis II will not land on the Moon or even enter lunar orbit. Instead, its primary objective is to rigorously test NASA’s Orion spacecraft on its first crewed flight. Engineers and mission controllers will evaluate every aspect of the spacecraft’s performance, from navigation and propulsion to life support systems, ensuring it is ready for future missions involving extended stays on the lunar surface.
NASA Administrator Jared Isaacman described the mission as a crucial first step in a broader campaign. Speaking ahead of launch, he called Artemis II “the opening act” in a sustained effort to send astronauts to and from the Moon regularly, ultimately supporting plans to build a lunar base and unlock both scientific and economic opportunities.
The launch itself came after weeks of delays due to technical issues, including hydrogen leaks in the rocket’s core stage and pressurization concerns in the upper stage. Even on launch day, engineers extended the countdown to resolve minor issues before giving the final “go” for liftoff.
At 6:35 p.m. EDT, the towering Space Launch System roared to life at Kennedy Space Center, generating a staggering 8.8 million pounds of thrust. Within seconds, the 5.7-million-pound rocket cleared the pad, accelerating rapidly as it climbed into the sky, producing a thunderous spectacle witnessed by tens of thousands along Florida’s Space Coast.
After shedding its solid rocket boosters and core stage, the Orion capsule entered orbit and began a carefully choreographed sequence of maneuvers. Within hours, the spacecraft reached an altitude higher than any crewed mission since the Apollo era. The astronauts, now weightless, began testing onboard systems, including communications, navigation, and even the capsule’s compact toilet—an early hiccup that was quickly resolved.
A key milestone came when Victor Glover assumed manual control of the spacecraft, demonstrating Orion’s handling capabilities by maneuvering it in close proximity to the spent upper stage. The exercise provided both technical data and valuable human feedback on how the spacecraft performs in real flight conditions.
Over the next day, mission controllers will assess Orion’s performance before giving approval for the critical “trans-lunar injection” burn—a six-minute engine firing that will propel the spacecraft out of Earth orbit and onto a trajectory toward the Moon. Once executed, the spacecraft will follow a “free-return” path, looping around the Moon and naturally heading back to Earth.
During the journey, the crew will travel as far as 252,800 miles from Earth, surpassing the record set during Apollo 13. As Orion passes behind the Moon, communication with mission control will briefly be lost, giving astronauts a rare opportunity to observe and document the lunar far side—regions never before seen directly by human eyes.
Christina Koch highlighted the scientific importance of the flyby, noting that lighting conditions may allow the crew to capture unprecedented imagery that could aid future research. Glover added that the mission represents a milestone in diversity and representation, bringing new perspectives to lunar exploration.
After completing their journey around the Moon, the spacecraft will return to Earth for a high-speed reentry. Traveling at nearly 25,000 mph, Orion’s heat shield will endure temperatures approaching 5,000 degrees before parachutes deploy to slow the capsule for a controlled splashdown in the Pacific Ocean on April 10. Recovery teams will then assist the astronauts before transporting them back to Houston.
The success of Artemis II will set the stage for future missions, including Artemis III, which aims to return humans to the lunar surface. NASA is also planning increasingly frequent lunar missions, potentially every six months, as part of a long-term vision to establish a sustainable base near the Moon’s south pole.
This renewed push comes amid a growing global competition in space exploration, particularly with China, which has announced plans to land its own astronauts on the Moon before the end of the decade.
Despite uncertainties surrounding long-term funding, Isaacman expressed confidence in the program’s future, emphasizing its role as a stepping stone to deeper space exploration—including eventual human missions to Mars. Beyond its scientific and technological goals, he said, Artemis is also about inspiration.
