SpaceX‘s mega rocket blasted off on another test flight Thursday, aiming to make it halfway around the world this time.

The first two flights last year lasted mere minutes before blowing up over the Gulf of Mexico.

Starship, the biggest and most powerful rocket ever built, soared from the southern tip of Texas near the Mexican border and headed out over the gulf. No people or satellites were on board.

The rocket and futuristic-looking spacecraft towers 397 feet (121 meters), easily exceeding NASA’s past and present moon rockets.
