SpaceX's Starship megarocket prepares for its tenth test flight amid reliability concerns.

SpaceX is preparing for its tenth test flight of the Starship megarocket on Sunday, following a series of recent failures that have raised questions about its reliability. The mission aims to fly the upper stage halfway around the world before splashing down in the Indian Ocean. Despite the setbacks, the Starship remains central to Elon Musk's plans for colonizing Mars and is also key to NASA's Artemis lunar lander program. The upcoming test is seen as crucial for SpaceX to address technical challenges and prove the rocket's viability.
