NASA Artemis II Astronauts Nearly Halfway to the Moon

HOUSTON – Floating in a cabin the size of a large camper van, four NASA Artemis II astronauts are currently carving a path through the stars that hasn’t been traveled by humans in over five decades. As of Saturday morning, April 4, 2026, the NASA Artemis II crew is roughly halfway to the moon, having successfully left Earth’s orbit behind.

The mission, which launched with a roar from the Kennedy Space Center on Wednesday evening, marks a turning point in human history. Commander Reid Wiseman, Pilot Victor Glover, and Mission Specialists Christina Koch and Jeremy Hansen are not just passengers on a rocket; they are the pioneers of a new era of lunar exploration.

A Flawless Start to a Deep Space Odyssey

The journey began on April 1 at 6:35 p.m. EDT. The Space Launch System (SLS), the most powerful rocket ever built by NASA, lit up the Florida coastline, carrying the Orion spacecraft into the night sky. Since then, the mission has proceeded with remarkable precision.

After spending their first 24 hours in a high Earth orbit to test life-support systems and manual piloting, the crew received the “go” for the most critical move of the trip: the Trans-Lunar Injection (TLI). This engine burn acted like a cosmic slingshot, pushing the Orion capsule out of Earth’s gravitational pull and setting it on a four-day trajectory toward the lunar far side.

“I’ve got to tell you, there is nothing normal about this,” Commander Reid Wiseman told Mission Control during a radio check-in. “Sending four humans 250,000 miles away is a herculean effort, and we are now just realizing the gravity of that.”

Life Aboard NASA Artemis II: The Daily Grind in Deep Space

While the world watches from below, the crew is busy maintaining the spacecraft and conducting science experiments. Space may look empty, but the interior of Orion is a hive of activity.

Systems Monitoring: The crew is constantly checking the radiation shielding and oxygen scrubbers.
Manual Maneuvers: Earlier in the flight, the team practiced “proximity operations,” manually moving the capsule to simulate docking procedures for future missions.
Photography: Astronauts have been capturing high-resolution images of Earth as it shrinks into a “blue marble,” as well as preparing to photograph the lunar south pole.
Health Checks: Doctors on the ground are monitoring how microgravity and deep-space radiation affect the human body over several days.

The living space is tight. With four people sharing a five-meter-diameter capsule, organization is key. Every meal, every workout, and every hour of sleep is carefully choreographed to ensure the mission remains on track.

Breaking Records and Making History

Artemis II is more than a repeat of the Apollo era. It is a mission of “firsts” that reflects a modern, inclusive approach to space.

First Woman: Christina Koch is officially the first woman to travel to the vicinity of the moon.
First Person of Color: Victor Glover is the first person of color to venture into deep space.
First International: Jeremy Hansen, representing the Canadian Space Agency, is the first non-American to leave low Earth orbit.
All-Time Distance Record: By Monday, April 6, the crew is expected to reach 252,799 miles from Earth. This will break the record set by the Apollo 13 mission in 1970.

The Road Ahead: The Lunar Flyby

The crew is currently in the “coasting” phase of the mission. Because they are on a “free-return” trajectory, the moon’s gravity will naturally pull them around its far side and sling them back toward Earth without the need for a major engine burn to turn around.

At their closest point, the astronauts will be about 4,600 miles above the lunar surface. From this vantage point, they will see the rugged, cratered landscape of the moon’s far side—a view no human has seen with their own eyes since 1972.

This flyby is a dress rehearsal for Artemis III, which aims to land humans on the lunar surface later this decade. By testing the Orion spacecraft with a human crew now, NASA is ensuring that the systems are safe for the next giant leap.

How to Follow the Mission

For those who want to watch history unfold in real-time, NASA has made it easier than ever. The agency’s “Artemis Real-time Orbit Website” (AROW) allows anyone to see Orion’s exact location, speed, and distance from both the Earth and the moon.

As the crew approaches the lunar environment, the excitement at Mission Control in Houston is palpable. “The nation, and the world, has been waiting a long time to do this again,” Wiseman said before the launch. Now, halfway there, that wait is almost over.

The Orion capsule is scheduled to splash down in the Pacific Ocean on April 10, concluding a 10-day mission that will likely be remembered as the moment humanity truly returned to the stars.
