NASA's Space Launch System (SLS) rocket successfully lifted off from Launch Pad 39B at Kennedy Space Center in Florida at 6:35 p.m. EDT on April 1, 2026. The Orion spacecraft is now on a meticulously planned test flight, set to take its crew on a journey around the Moon and back to Earth.
"This launch signifies a pivotal moment for our nation and for all who cherish exploration. Artemis II continues the vision initiated by President Donald J. Trump, marking humanity's return to the Moon after over 50 years and heralding a new era of lunar exploration beyond Apollo," stated NASA Administrator Jared Isaacman. "With four exceptional astronauts aboard, this mission is not just a test; it is the beginning of a larger journey toward establishing a sustainable presence on the Moon and beyond."
Meet the Artemis II Crew and Mission Objectives
The mission is anticipated to last approximately 10 days, featuring NASA astronauts Reid Wiseman, Victor Glover, and Christina Koch, alongside CSA astronaut Jeremy Hansen. As the inaugural crewed mission of NASA's Artemis program, Artemis II aims to validate essential systems with astronauts onboard and lay the groundwork for future missions focused on a long-term human presence on the Moon and eventual travel to Mars.
Shortly after launch, Orion deployed its solar array wings to harness solar energy. The crew and ground teams began transitioning the spacecraft into standard flight operations while monitoring critical onboard systems.
"Artemis II is a test flight, and we have just begun," remarked NASA Associate Administrator Amit Kshatriya. "The team behind this vehicle has equipped our crew with the necessary tools to demonstrate its capabilities. Over the next 10 days, Reid, Victor, Christina, and Jeremy will rigorously evaluate Orion to ensure future crews can land on the Moon with confidence. We are embarking on a long-term campaign, with the challenges ahead surpassing those behind us."
Orion's Path from Earth to the Moon
Approximately 49 minutes post-launch, the rocket's upper stage ignited to place Orion into an elliptical orbit around Earth. A subsequent burn will elevate the spacecraft, aptly named "Integrity" by the crew, into a high Earth orbit reaching about 46,000 miles. Following this maneuver, Orion will separate from the rocket stage and continue its mission autonomously.
Hours later, the upper stage will release four CubeSats, developed by international partners, which will conduct scientific studies and technology demonstrations.
Orion will remain in high Earth orbit for about a day, during which the astronauts will manually pilot the spacecraft to assess its performance. Teams at NASA's Johnson Space Center in Houston will collaborate closely with the crew to evaluate onboard systems.
Lunar Flyby and Homeward Journey
If all systems function as intended, mission control will command Orion's European-built service module to perform a translunar injection burn on April 2. This maneuver, lasting approximately six minutes, will direct the spacecraft toward the Moon, utilizing its gravitational pull to facilitate the return journey to Earth.
During the lunar flyby on April 6, the astronauts will spend hours observing and photographing the Moon, becoming the first humans to directly witness certain regions of its far side. The unique lighting conditions will cast long shadows, revealing features like ridges and crater edges that are often less visible under full sunlight. The crew will also engage in scientific studies, including human health research to support future missions.
Following the flyby, Orion is set to return to Earth, with the crew expected to splash down in the Pacific Ocean.
Towards a Sustainable Lunar Future
Artemis II is a crucial part of a larger initiative aimed at expanding human exploration beyond the Moon. NASA's future missions will progressively increase in complexity, fostering scientific discovery, economic growth, and paving the way for sending astronauts to Mars. This mission not only signifies a step forward in exploration but also embodies the dawn of a new era of innovation, striving for a permanent human presence on the Moon and deeper space exploration.
