The company SpaceX, owned by billionaire Elon Musk, canceled the test flight of its Starship megarocket, the latest setback for the launch vehicle after recent attempts that ended in explosions.

At 123 meters tall, the Starship is the tallest launch vehicle largest and most powerful ever built. It aims to return Americans to the Moon and is key to fulfilling Musk's dream of colonizing Mars.

The rocket was scheduled to launch from South Texas at 6:30 p.m. local time (12:30 a.m. CET on Monday). However, about 15 minutes beforehand, SpaceX announced that the launch was canceled.

“Today’s 10th Starship flight is being scrapped to allow time to resolve a ground systems issue,” SpaceX said on its X account.

Repeated explosions that showered debris over the Caribbean and disrupted flights in recent months have increased pressure on SpaceX to conduct a trouble-free test.

SpaceX did not announce a new launch date, but the company’s website launched a countdown that suggested an attempt would be made on Monday.

Given planned road closures around Star base, Starship’s 10th flight could still take place as early as Monday or Tuesday.

The hour-long uncrewed mission was intended to test the upper body in flight around Earth while the inner boosters would fall into the Indian Ocean.
