SpaceX CEO Elon Musk wants to send a cargo ship to Mars by the end of next year. Here’s why that plan likely won’t pan out.

SpaceX's massive Starship spacecraft exploded into a dramatic fireball during testing in Texas late on Wednesday, the latest in a series of setbacks for billionaire Elon Musk’s Mars rocket program.The explosion occurred around 11 p.

Starship is being developed as a fully reusable transportation system. This means the rocket and spacecraft will be able to return to the ground for additional missions. In the coming years Starship is intended to carry cargo and humans to the moon and outside of earth’s orbit.
