NASA's Artemis Program Hits Major Roadblock: Engine Failure Forces Delay A major setback has been reported in NASA's ambitious Artemis program, which aims to return humans to the lunar surface by 2025. According to sources, a critical engine failure during a recent test has forced the space agency to delay the program's next crucial step. The Artemis program, named after the Greek goddess of the hunt, is a highly complex and expensive undertaking that seeks to establish a sustainable presence on the lunar surface. With the engine failure, NASA will need to reassess its timeline and make significant adjustments to ensure the program's success.
