CTOnews.com, April 17 (Xinhua) 21:19 EDT on the 17th, the launch of the SpaceX Starship heavy carrier rocket was postponed about 40 seconds before its first test flight, due to a problem with the pressurization system of the super-heavy booster.

SpaceX said it expected it would take at least 48 hours, or at least 19 days, to try again, but it was not clear when. Musk, founder of Space, said on Twitter, "the pressure valve of the starship seems to be frozen and unless it resumes work immediately, it will be very difficult to launch today."

According to the original plan, the Starship will separate from the booster rocket and reach orbital speed after about 3 minutes of flight. Its first flight test will not complete low-Earth orbit, and if successful, it will fly about 150 miles above the surface, enter what is thought to be outer space, and eventually splash down in the Pacific Ocean near Hawaii. the whole flight is expected to last only 90 minutes.

Musk also gave his opinion yesterday and tried to lower expectations for the starship test. "I think I just want to set expectations lower."if we were far enough away from the launch pad before something went wrong, then I think I would think it was successful. as long as we don't blow up the launch pad."

The super heavy booster and the top starship are stacked nearly 400ft (CTOnews.com Note: about 12192 centimeters), and the booster alone carries 33 engines.

Bill Nelson (Bill Nelson), director of NASA, likes to brag about his giant lunar rocket space launch system (SLS). But the starship system has almost twice as much thrust as the SLS rocket; and NASA's SLS rocket crashes into the sea after launching a payload, but the starship system is designed to return to the ground after launch and then use it again.

If SLS represents the traditional method of rocket design, then the starship system is a symbol of modern space flight. Starships are designed to have the ability to refuel in orbit, which allows SpaceX to send large amounts of cargo and dozens of people into distant space. And starships are reusable and are expected to cost much less than SLS.

The launch will be SpaceX's first attempt to launch the entire starship system, including both super-heavy booster and top starship. Considering the size and complexity of the overall system, a successful launch will be a feat. "the measure of success in this test is how much we can learn from it," SpaceX said in a statement. "in the process of SpaceX's rapid progress in starship development, this test will provide more information and improve the probability of success in the future."
