SpaceX calls off 1st launch attempt of giant new rocket

SpaceX called off its first launch attempt of its giant rocket on Monday.

Elon Musk and his company had planned to launch the nearly 400-foot Starship rocket from the southern tip of Texas, near the Mexican border. SpaceX postponed the launch because of a problem with the first-stage booster.

No people or satellites were aboard for this attempt. There won’t be another try until at least Wednesday.

The company plans to use Starship to send astronauts and cargo to the moon and, ultimately, Mars.
