NASA's Artemis Program Hits Major Milestone as Orion Spacecraft Embarks on Uncrewed Test Flight In a significant step forward for the US space agency's ambitious Artemis program, NASA has successfully launched an uncrewed test flight of its Orion spacecraft, marking a major milestone in the mission to return humans to the lunar surface by 2025. The spacecraft, designed to carry astronauts on the Artemis missions, has been propelled into space atop a Space Launch System (SLS) rocket and is now embarking on a 25-day journey to the Moon and back. The uncrewed test flight, known as Artemis I, will provide invaluable insights into the performance and capabilities of the Orion spacecraft, paving the way for future crewed missions to the lunar surface. With this successful launch, NASA is one step closer to achieving its goal of establishing a sustainable presence on the Moon and eventually sending humans to Mars.
