The world is watching the skies today, Monday, April 6, 2026, as the NASA Artemis II mission enters its most anticipated phase. Now on Day 6 of a 10-day journey, four astronauts are preparing for a historic lunar flyby, venturing farther into deep space than any human beings in history.
This critical test flight represents the first crewed mission of the Space Launch System (SLS) rocket and the Orion spacecraft. While the mission does not include a lunar landing, it serves as the essential final demonstration of the spacecraft’s life-support and navigation systems before NASA attempts to return humans to the lunar surface for the first time since the Apollo era ended in 1972 according to mission schedules.
The crew—consisting of NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, alongside Canadian Space Agency astronaut Jeremy Hansen—launched from Florida on April 1. As they approach the moon, the mission transitions from a series of orbital tests to the primary objective: a high-stakes flyby that will test the limits of the Orion capsule, named Integrity.
The Crew Venturing into Deep Space
The Artemis II crew is a milestone in itself, reflecting a new era of inclusive exploration. The mission includes the first woman, the first Black man, and the first Canadian to venture on a lunar mission as reported by USA Today. The crew is led by Commander Reid Wiseman, supported by Pilot Victor Glover and Mission Specialists Christina Koch and Jeremy Hansen.
For these four individuals, the mission is a rigorous exercise in endurance and precision. Over the course of their 10-day voyage, they are responsible for monitoring the Orion spacecraft’s performance in the harsh radiation environment of deep space, ensuring that the systems designed to protect humans are functioning as intended before the more complex landing missions of the future.
Technical Milestones of the Orion Spacecraft
The journey began with a successful liftoff from Launch Complex 39B at NASA’s Kennedy Space Center in Florida on Wednesday, April 1, 2026 via NASA’s official updates. The SLS rocket, the most powerful rocket ever built for human spaceflight, propelled the crew out of Earth’s atmosphere and into a trajectory toward the moon.
Shortly after launch, the spacecraft achieved a critical configuration milestone: the full deployment of its Solar Array Wings (SAWs). These four wings, which extend from the European Service Module, provide the spacecraft with a total wingspan of approximately 63 feet according to NASA flight controllers. Each wing contains 15,000 solar cells that convert sunlight into electricity, utilizing a two-axis rotation system to track the sun and maximize power generation as the spacecraft changes its attitude during the outbound journey.
To reach the moon, the NASA Artemis II mission relied on a series of precise orbital maneuvers. Following the initial launch, the crew performed the Perigee Raise Maneuver (PRM) and the Apogee Raise Burn (ARB). These burns were designed to increase the lowest and highest points of the Orion spacecraft’s orbit, effectively pushing the crew out of Earth’s immediate orbit and preparing them for the transition into deep-space operations as detailed by NASA.
The Path to a 2028 Lunar Landing
While the current focus is on the lunar flyby, the broader goal of the Artemis program is far more ambitious. Artemis II is primarily a test mission, a “giant step” intended to prove that the Orion crew capsule can safely handle a lunar mission with humans aboard. This mission is the prerequisite for the subsequent landing missions.
NASA’s current roadmap suggests that a crewed lunar landing could be attempted as early as 2028 according to mission projections. By orbiting the moon without landing, the crew of Artemis II is gathering essential data on communication, navigation, and the human physiological response to deep-space travel.
This mission bridges the gap between the uncrewed Artemis I flight of 2022 and the eventual return of humans to the lunar surface. The success of the current flyby will provide the confidence needed to proceed with the landing phase, marking the first time humans will have walked on the moon in over five decades.

Timeline for Return and Splashdown
Following the lunar flyby today, the crew will initiate the journey back toward Earth. The return phase is as critical as the outbound journey, as the Orion spacecraft must hit a precise atmospheric entry corridor to ensure a safe descent.
NASA expects the mission to conclude with a splashdown in the waters off the coast of California on Day 10 of the flight via NASA’s flight tracker. This will mark the end of the 10-day odyssey and the successful completion of the first crewed test of the Artemis architecture.
For those following the mission in real-time, NASA maintains an online tracker that provides live data on the Orion spacecraft’s speed, its distance from Earth, and its proximity to the moon. This transparency allows the global public to witness the mission’s progress as the crew pushes the boundaries of human exploration.
The next confirmed checkpoint for the mission is the completion of the lunar flyby and the subsequent initiation of the trans-Earth injection burn to bring the crew home. We will continue to provide updates as the spacecraft begins its return journey.
