To fulfill its promise of reaching the Moon and Mars, SpaceX needs a really big rocket. Like, really big. The latest version of Starship is the largest and most powerful megarocket ever built, and it just hit a critical milestone.

The U.S. Space Force has swapped rockets for an upcoming GPS satellite launch, moving to a SpaceX Falcon 9 while the investigation into an anomaly with ULA's Vulcan Centaur continues.

Residents were warned they might hear a sonic boom as part of the launch.

SpaceX is aiming to build Starship rockets at an unprecedented pace. At its Starfactory in Texas, the company is developing a new manufacturing system designed for continuous production. The goal is to produce up to 100 rockets per year—and eventually far more.
