SpaceX's Starship V3 Test Flight Ignites Sector Momentum

According to the user‑provided details, SpaceX managed to pull off a rough but ultimately successful test of its upgraded Starship V3 on Friday. All 33 Raptor engines fired at liftoff, the vehicle reached space, and it deployed 20 Starlink mass simulators even after losing one of its upper‑stage engines.

Engineers also sent two functional Starlink satellites equipped with flashlights to capture footage of Starship's heat shield during separation, a key step in proving the rocket's reusability.
