SpaceXs first full-size stainless steel Starship test vehicle stands some 164 feet (50 meters) tall and measures wider than the cabin of a Boeing 747 jumbo jet. If Elon Musk has his way, it will fly to an altitude of 65,000 feet (20 kilometers) before the end of the year.

These photos taken Saturday show the Starship shining in the Texas sun before Elon Musk took the stage at Boca Chica, Texas, to present an update on SpaceXs plans for a gigantic next-generation rocket and spacecraft designed to carry cargo and crews to Earth orbit, the moon, Mars and other destinations in the solar system.

The vehicle measures 30 feet (9 meters) wide, and features movable fins and canards to provide aerodynamic stability in flight. Not visible in these images are three methane-fueled Raptor engines, which sit inside an aft skirt and can generate more than 1.3 million pounds of collective thrust at full throttle.

Future Starship vehicles will have six Raptor engines, and will be mounted atop SpaceXs Super Heavy booster for missions into Earth orbit and beyond. The entire stack will stand around 387 feet (118 meters) tall.

Up to 37 Raptor engines will power the Super Heavy booster, producing more than 16 million pounds of thrust at liftoff, according to SpaceX.

The Starship and Super Heavy will be fully reusable, SpaceX says, and capable of vertical takeoffs and landings.
