SpaceX Starship 25 successfully static fired its six raptor engines ahead of the next test flight. The rocket’s engines were briefly ignited while the vehicle remains anchored to the ground, as Elon Musk stated that Ship 25 could be tested as soon as early August.
When fully stacked, Starship stands 394-feet tall and will be the largest as well as most powerful rocket built to date. The first-stage booster, known as Super Heavy, consists of 33 Raptor engines that generate 16.7-millino pounds of thrust at liftoff. For comparison, that is almost twice the thrust of NASA’s Space Launch System (SLS) rocket.

- This space rocket toy for children comes with a service vehicle, planet rover, drone & 6 LEGO astronaut minifigures for creative space play
- Packed with LEGO minifigure accessories, like a space rover model with a pretend light brick-cutting laser that shines a red light (battery included)
So, we made a sort of late-breaking change that’s really quite significant to the way that stage separation works, which is to use hot staging. The superhot plasma from the upper-stage engines has gotta go somewhere. So we’re adding an extension to the booster that is almost all vents, essentially. So that allows the the upper-stage engine plume to go through the sort of vented extension of the booster and not just blow itself up,” said Elon Musk, SpaceX Chief Engineer.
