The Space Telescope is a payload launched in Mission 4 where it must be left within a green area. There, it is visited in Mission 10 where it must be refueled with thruster propellant, and again in Mission 24 where its batteries are replaced.
It can take screenshots, like the lunar and LK modules, the Pod and the Voyager-X Antenna. However, it has limited movement from where you put it, as the telescope has no main engine and as it does not provide displacement laterally, forwards or backwards. The thrusters have a abnormally high displacement capacity because of this, however.
This huge displacement capacity makes it a perfect fit for controlling the pitch of a space station, as it's one end can be docked to a space station. One unit of thruster fuel can provide a good amount of torque to the station.
- A Space Telescope is also used as the enemy spy satellite in Mission 7, but with a different texture.
