**NASA's Artemis Program Hits a Snag: Rocket Engine Fails During Critical Test** In a major setback for NASA's ambitious Artemis program, a critical test of the Space Launch System (SLS) rocket engine has ended in failure. The SLS is designed to propel the Orion spacecraft on its mission to return humans to the lunar surface by 2025. However, a recent test of the rocket's core stage engine has revealed a serious issue, casting doubts over the program's ability to meet its tight deadline. The Artemis program aims to establish a sustainable presence on the moon and ultimately send humans to Mars. If the SLS engine problem is not resolved quickly, it could jeopardize the entire mission timeline.
