SpaceX prepares for sixth Starship test flight with new objectives

SpaceX is set for its sixth test flight of the Starship, the tallest and most powerful rocket ever built, today at 5 p.m. ET. The launch was rescheduled from Monday and will take place at the Starbase facility in Texas. Key differences in this flight include the plan to ignite one of Starship's engines in space, a first for the program. This test is crucial for future missions, as it will help determine if the rocket can be controlled in orbit. President-elect Donald Trump is attending the launch, expressing support for Elon Musk and the SpaceX team. The previous test flight in October was successful, with the Super Heavy booster being caught mid-air after its return.
