SpaceX's Starship Rocket Fails to Reach Space on Second Test Flight

SpaceX's Super Heavy-Starship rocket, the most powerful rocket ever built, launched on its second test flight but failed to reach space. The Super Heavy booster broke apart soon after launch, and the Starship upper stage was lost as well. The flight was intended to test the "hot-staging" system for separating the upper and lower stages. SpaceX had made numerous changes to improve safety and performance following a previous test flight failure in April. The rocket is crucial for SpaceX's plans to expand its fleet of Starlink internet satellites and enable low-cost government and commercial flights to the moon, Mars, and beyond.
