Starship's fifth flight test could launch as soon as October 13, pending regulatory approval.
Starship Flight 4 was a tremendous success. A fully successful ascent was followed by the first ever booster soft-landing in the Gulf of Mexico and Starship making it through a brilliant reentry, before its own landing burn and splashdown in the Indian Ocean.
The fifth flight test of Starship will aim to take another step towards full and rapid reusability. The primary objectives will be attempting the first ever return to launch site and catch of the Super Heavy booster and another Starship reentry and landing burn, aiming for an on-target splashdown of Starship in the Indian Ocean.
Flight 5 Vehicles Upgrades
Extensive upgrades ahead of this flight test have been made to hardware and software across Super Heavy, Starship, and the launch and catch tower infrastructure at Starbase.
SpaceX engineers have spent years preparing and months testing for the booster catch attempt, with technicians pouring tens of thousands of hours into building the infrastructure to maximize the chances for success.
“ We accept no compromises when it comes to ensuring the safety of the public and our team, and the return will only be attempted if conditions are right” SpaceX
Thousands of distinct vehicle and pad criteria must be met prior to a return and catch attempt of the Super Heavy booster, which will require healthy systems on the booster and tower and a manual command from the mission’s Flight Director.
“If this command is not sent prior to the completion of the boostback burn, or if automated health checks show unacceptable conditions with Super Heavy or the tower, the booster will default to a trajectory that takes it to a landing burn and soft splashdown in the Gulf of Mexico” SpaceX
The returning booster will slow down from supersonic speeds, resulting in audible sonic booms in the area around the landing zone. Generally, the only impact to those in the surrounding area of a sonic boom is the brief thunder-like noise with variables like weather and distance from the return site determining the magnitude experienced by observers.
Starship will fly a similar trajectory as the previous flight test with splashdown targeted in the Indian Ocean. This flight path does not require a deorbit burn for reentry, maximizing public safety while still providing the opportunity to meet Spacex primary objective of a controlled reentry and soft water landing of Starship.
One of the key upgrades on Starship ahead of flight was a complete rework of its heatshield, with SpaceX technicians spending more than 12,000 hours replacing the entire thermal protection system with newer-generation tiles, a backup ablative layer, and additional protections between the flap structures. This massive effort, along with updates to the ship’s operations and software for reentry and landing burn, will look to improve upon the previous flight and bring Starship to a soft splashdown at the target area in the Indian Ocean.
