The first launch of Starship, the world's largest rocket, will not take place Monday because of a technical problem. "A valve appears to be frozen," SpaceX boss Elon Musk tweeted earlier.

The launch of this giant was planned from the Starbase space base, in the extreme south of Texas in the United States. At 120 meters high, Starship belongs to the category of super-heavy launchers, capable of carrying more than 100 tons of cargo in orbit. Its take-off power must be more than twice that of the legendary Saturn V, the rocket of the Apollo lunar program.
