SpaceX Gears Up for Sixth Starship Test Flight with New Reusability Goals

The launch window is scheduled to open at 4:00 p.m. CT, with a 30-minute live webcast set to begin beforehand. Viewers can tune in via SpaceX’s X account and the new X TV app. However, due to the dynamic nature of testing, the timeline may shift, so SpaceX advises followers to stay updated through its social media channels.

The previous Starship test marked a major milestone, as the Super Heavy booster returned successfully to Starbase and was caught by the launch and catch tower’s “chopstick” arms. This achievement provided essential data for refining the hardware and software systems that drive the mission. In that same flight, the upper stage of Starship demonstrated several upgrades, achieving a controlled splashdown in the Indian Ocean with improved accuracy.

The sixth test aims to expand Starship’s capabilities by incorporating more complex maneuvers and enhancing vehicle resilience. Key goals include another booster return and catch attempt, reigniting a Raptor engine in space, and testing upgraded heatshield technology. Modifications for this flight add redundancy to the booster propulsion systems, strengthen the booster’s structure, and streamline post-landing procedures to offload propellants more efficiently. SpaceX engineers have also enhanced the software that controls the booster’s trajectory and return process, ensuring greater reliability and safety.

As with previous flights, the Super Heavy booster’s catch will depend on achieving certain criteria for both the vehicle and the launch tower. The mission’s Flight Director will make the final decision to initiate the catch sequence based on real-time conditions. If any component, such as the booster or tower, does not meet the necessary conditions, the booster will be redirected to perform a controlled splashdown in the Gulf of Mexico. Safety remains a top priority for SpaceX, with the catch only proceeding if all criteria are met.

Local observers may hear a series of sonic booms as the booster decelerates from supersonic speeds upon return. These sound waves will manifest as brief, thunder-like noises, with their intensity varying based on factors like weather and proximity to the landing area.

The upper stage will follow a similar suborbital path as in the previous test, with splashdown expected in the Indian Ocean. A notable addition to this mission is an in-space burn test of a single Raptor engine, an advancement that could pave the way for ship deorbit burns ahead of future orbital missions. The spacecraft will also undergo thermal protection trials to better assess its heat shield, with new materials and configurations exposed to the extreme conditions of reentry. Starship will attempt a higher angle of descent to push the limits of flap control and further study future landing profiles.

This mission’s afternoon launch window is designed to allow for daylight reentry over the Indian Ocean, enhancing visual observations for SpaceX engineers.

Looking ahead, the seventh flight test of Starship will feature further upgrades, including redesigned forward flaps, larger propellant tanks, and the latest thermal protection technology. SpaceX aims to continue iterating with each flight to bring Starship closer to its ultimate goal: a reliable, fully and rapidly reusable launch system that will enable new possibilities in space exploration.
