• NASA's Artemis II crew, including three Americans and one Canadian, has successfully left Earth's orbit.
• The Orion capsule's engine burn achieved speeds necessary for a lunar trajectory.
• This mission marks the first crewed journey to the Moon since 1972.
• The astronauts will travel farther from Earth than any humans before, up to 252,455 miles.
• The Artemis program aims to establish a sustainable human presence on the Moon.

NASA's Artemis II mission achieved a historic milestone when its crew successfully departed Earth’s orbit, heading towards the Moon on Thursday evening. This key moment followed the approval from NASA's mission management team for a critical engine burn during which the shuttle-era Orbital Maneuvering System engine was ignited. This burn accelerated the Orion capsule to approximately 25,000 mph for a four-day journey to the Moon, according to CBS News.

At around 7:50 p.m. EDT, the burn, lasting nearly six minutes, propelled the crew into a "free-return" trajectory, utilizing the Moon's gravitational pull to aid their journey back to Earth. “The crew is feeling pretty good up here on our way to the Moon,” remarked astronaut Jeremy Hansen during the mission, reflecting the crew's enthusiasm following the engine burn, as reported by South China Morning Post.

The Artemis II mission is notable as it marks the first crewed lunar flyby in over 50 years. NASA's team includes American astronauts Reid Wiseman, Victor Glover, Christina Koch, and Canadian astronaut Jeremy Hansen, making it a landmark mission that embodies innovation and international collaboration in space travel, according to Le Monde and Anadolu Agency.

The mission's primary goal is to test the operational capabilities of the Orion spacecraft, paving the way for future lunar landings planned for 2028. This flight is a make-or-break test, not just for the Artemis program but for the broader vision of sustainable human exploration of the Moon and beyond, as articulated by NASA Chief Jared Isaacman during a mission update. He highlighted the importance of this endeavor in the context of global competition in space exploration, reflecting on the implications of this undertaking with regard to international rivalry, as shared by CBS News and South China Morning Post.
