The upcoming mission will mark the debut of SpaceX's next-generation Starship and Super Heavy vehicles, featuring upgraded Raptor engines and launching from a newly built pad at Starbase.

SpaceX described Starship as the critical enabler of the aerospace giant’s multiplanetary ambitions and long-term growth plans. Starship is a reusable rocket, with SpaceX aiming to reduce the cost of reaching orbit by 99% or more relative to the historical average launch cost.

SPCX Details Starship V3 Changes

SpaceX detailed a slew of changes to Starship V3, stating that it features a major propulsion redesign with upgraded Raptor engines, larger propellant tanks, improved flight-control systems, and a lighter, more reliable vehicle architecture.

Starship V3 also includes a faster Starlink satellite deployment system, enhanced capabilities for long-duration missions, and hardware for in-space docking and propellant transfer.

The vehicle will debut advanced avionics with improved autonomous navigation, propellant monitoring, and expanded camera coverage supported by high-speed Starlink connectivity.

Flight 12 will be the first Starship launch from Starbase’s new Pad 2, which features upgraded fueling, launch tower, and launch mount systems designed to improve reliability and turnaround times. The enhancements are aimed at enabling rapid reusability, in-space refueling, Starlink deployments, and future missions to the Moon and Mars.

SPCX IPO Could Make Elon Musk World’s First Trillionaire

According to the Bloomberg Billionaires Index, Musk’s net worth currently stands at $676 billion. Per a Bloomberg analysis, his net worth could surpass $1.1 trillion if SpaceX reaches a $2 trillion valuation.

Even at a $1.75 trillion valuation, his holdings in SpaceX, Tesla Inc. (TSLA), and other ventures would still be enough to push him past the trillion-dollar mark.

TSLA stock is down 7% year-to-date, but up 25% over the past 12 months. The S&P 500 ETF (SPY) is up 27% over the past 12 months, while the Invesco QQQ Trust ETF (QQQ) is up 38%.
