The article discusses SpaceX's progress towards the second integrated test flight of their Starship spacecraft. SpaceX faced issues during the first test flight, but has since made changes and upgrades to the rocket and launch process. The FAA is currently reviewing changes to determine if launch approval can be granted, but SpaceX is optimistic about potential approval next month. Numerous changes have been made to improve Starship's reliability and safety, and the integrated test flights allow for quick learning and improvement.
Sure, here are the key facts extracted from the provided text:
**First Integrated Test Flight:**
1. The first integrated test flight of Starship lasted just under 4 minutes.
2. The flight termination system activated and destroyed both the booster and upper stage.
**Data from First Flight:**
