SpaceX has stacked its latest Starship Version 3 rocket at its launch pad in South Texas, achieving a height of 408 feet (124 meters), making it the tallest rocket ever constructed. This version boasts several enhancements, including higher-thrust Raptor engines on both the Super Heavy booster and the Starship upper stage, as well as a new lattice-like structure for hot staging. Notably, it features three modified grid fins for improved recovery of the first stage. Starship V3 is pivotal for SpaceX's plans to master in-orbit refueling, a necessary capability for future missions beyond low-Earth orbit, including serving as landers for NASA’s Artemis program aimed at returning humans to the Moon. Although SpaceX has not confirmed an exact launch date, recent maritime warnings suggest a potential launch attempt on May 19 from the Gulf Coast site near Brownsville, Texas. This marks a significant step in SpaceX's ongoing iterative development of its Starship program.
