HOUSTON — Space agencies confirmed on Thursday that the initial phase of the Artemis II mission has been successfully completed, following the spacecraft’s launch and early in-flight operations, according to officials from NASA and its international partners.
NASA said the Orion spacecraft, carrying four astronauts, is performing as expected after reaching space and beginning its planned trajectory away from Earth. The agency described early mission milestones — including spacecraft separation, power-up procedures, and initial system checks — as proceeding “nominally,” according to an official mission update released late Wednesday.
“The spacecraft is healthy, and the crew is doing well as we move through these early mission phases,” NASA said in a statement, adding that teams are continuing to monitor life-support, propulsion, and communication systems.
Artemis II, launched from the Kennedy Space Center in Florida, is the first crewed mission of NASA’s Artemis program and the first time humans have traveled beyond low-Earth orbit in more than 50 years, the agency said. The mission builds on the uncrewed Artemis I flight conducted in 2022 and is designed to test systems required for future lunar exploration.
According to NASA, the four-person crew is expected to spend about 10 days in space, flying around the Moon and returning to Earth without landing. The mission uses the Space Launch System rocket and Orion spacecraft, both being tested with astronauts aboard for the first time.
Officials said the initial phase includes critical operations shortly after launch, such as deployment of solar arrays, verification of onboard navigation systems, and checks of environmental controls that sustain the crew. These steps are considered essential before the spacecraft proceeds toward deeper space, NASA officials said.
The Canadian Space Agency, which has one astronaut aboard, said in a separate update that coordination between international teams has been “smooth” during the early hours of the mission, though it did not provide detailed technical data.
Experts have previously noted that Artemis II is a key test of crewed deep-space capabilities, particularly following technical issues observed during Artemis I, including concerns related to the spacecraft’s heat shield. Addressing those issues is part of the mission’s broader objectives, NASA has said.
Despite the positive early assessment, officials cautioned that the mission remains in its initial stages. “We are still early in the flight, and teams will continue to evaluate performance as the mission progresses,” NASA said.
As of Thursday, the Orion spacecraft remains on its planned trajectory, with additional system evaluations and course adjustments scheduled in the coming days, according to NASA. Further updates on mission progress are expected as the crew approaches the next phase of its journey toward the Moon.
