How to watch SpaceX launch Starship for the second time live

In less than twenty-four hours, SpaceX will attempt to launch Starship into space for the second time. The official launch window opens at 7:00 AM CST on Saturday and lasts just twenty minutes – and no, that’s not a typo.

SpaceX will begin its live webcast tomorrow about 35 minutes before liftoff and will host the video on its website and on its social media page on X (Another company of SpaceX CEO Elon Musk).

Here is a brief rundown of the series of events we will see tomorrow morning. About two hours before launch, SpaceX’s flight director will verify continuity for propellant loading. First, the Super Heavy booster will be loaded with liquid oxygen and liquid methane, then the upper stage (the upper stage is also called the Starship).

About twenty minutes before lift-off, the engines of the Starship’s Raptor – 33 in the booster and six in the upper stage – will begin to cool down before ignition. Ten seconds before launch, SpaceX will activate its flame deflector, a large water deluge system located under the orbital launch mount. That system will flood the base of the rocket with water to absorb noise, prevent some vibrations and protect the launch infrastructure from the awesome power of the Raptor’s engines.

The ignition sequence starts at T-3 seconds. Then … in Musk’s words, “excitement is guaranteed.”

Standing at nearly 400 feet tall, the Starship is the largest rocket ever built. There’s already a lot riding on these tests: Starship is booked to take astronauts to the moon in 2025 (like, two years away) and eventually crew and cargo to Mars. The first orbital flight test in April ended prematurely when two rocket stages failed to separate. SpaceX intentionally detonated the vehicle in mid-air over the Gulf of Mexico about four minutes after liftoff after it began to fall uncontrollably back to Earth. Given the first test results, if SpaceX can go a little further – achieve separation of the stage, or advance even after launch – that would be a big win.

SpaceX introduced a number of upgrades this time around – including a water deluge system and a new way to implement stage separation called “hot staging,” where the long stage of Starship fires to push the booster away. These upgrades will also be tested.

The company’s ultimate goal for the flight test is to send the Starship on the upper stage on a journey almost halfway around the world and land it in the Pacific Ocean.
