SpaceX Sets May 19 Target for Record‑Tall Starship V3 Launch

*TL;DR: SpaceX plans a May 19 launch attempt of the 408‑foot Starship V3, the tallest and most powerful version yet, equipped with upgraded Raptor engines, a reusable lattice for hot staging, and three modified grid fins.

Context SpaceX has stacked a new Starship version at its Starbase facility near Brownsville, Texas, for the third time in three years. The vehicle, dubbed Starship V3, surpasses its predecessor by a few feet, reaching 408 feet (124 m). The launch pad sits just north of the U.S.–Mexico border, a site that has hosted multiple high‑altitude test flights.

Key Facts - The launch window is set for Tuesday, May 19, after a weekend delay pushed the target back from an earlier Friday estimate. - Starship V3 carries upgraded Raptor engines on both the Super Heavy booster and the upper stage; these engines deliver higher thrust and better fuel efficiency than earlier models. - A new reusable lattice structure replaces the previous metal skirt at the top of the booster, enabling “hot staging,” where the upper stage ignites before the booster separates, reducing gravity losses. - The vehicle now uses three modified grid fins instead of four; these aerodynamic surfaces guide the booster back to a controlled landing after separation. - Ground crews completed the stacking of the upper stage onto the booster on Saturday, marking the first full assembly of the V3 configuration.

What It Means If the May 19 attempt succeeds, Starship V3 will become the launch system SpaceX intends to use for in‑orbit refueling trials. Mastering refueling is a prerequisite for missions beyond low‑Earth orbit, including NASA’s Artemis lunar lander role. The upgraded engines and hot‑staging capability promise higher payload capacity, bringing the Moon and eventually Mars within reach. The reduction to three grid fins simplifies the recovery sequence, potentially increasing turnaround speed for reusable flights.

The next milestone will be a successful ascent and booster recovery, followed by a series of orbital tests that validate refueling and deep‑space performance. Watch for live coverage on May 19 and subsequent updates on SpaceX’s roadmap toward lunar and interplanetary missions.
