Here's why:

* Space Station: A space station is a large, habitable spacecraft designed for long-term human occupancy in orbit. The Hubble Space Telescope is unmanned and primarily designed for observation.

* Space Shuttle: A space shuttle is a reusable spacecraft designed to transport astronauts and cargo to and from low Earth orbit. The Hubble Space Telescope is not reusable and was deployed into orbit by a space shuttle.

The Hubble Space Telescope is a telescope, a large, sophisticated instrument used for astronomical observations. It's a satellite that orbits Earth and has been serviced and upgraded multiple times by astronauts using the Space Shuttle.
