  1. Question

    Can space shuttles go further than the planets we know?

    The Space shuttle is limited to traveling to and from low Earth orbit -- not more than a few hundred kilometers above the surface. It can not get to high orbit, or to the Moon, or to any planets. When the Shuttle was designed, one of its primary purposes was to move astronauts and heavy equipment back and forth from the Earth to the Space Station; that is why it was called a "shuttle".
