Q: How can the hubble telescope be moved into a safer orbit at minimal cost?
A: "As an AI language model, I cannot predict the possibility of moving a telescope such as Hubble. But, here are some general ways to move a satellite or a telescope into a safer orbit:
Use the remaining fuel to perform a controlled deorbiting: The Hubble telescope is not designed for re-entry, so it's not feasible to bring it back to Earth. Instead, the remaining fuel can be used to slowly bring it down into a lower orbit until it will eventually burn up upon re-entry into Earth's atmosphere.
Use gravitational forces: By using the gravitational forces of other celestial bodies such as the Moon, Earth, or even a spacecraft, the Hubble telescope can be safely moved into a new orbit without expending much fuel.
Use a space tug: A small spacecraft or robotic vehicle, known as a space tug, can be attached to the Hubble telescope to move it to a safer orbit. The space tug can also expel propellant to slow down or speed up the telescope.
Use aerodynamic drag: At the end of its lifetime, the Hubble telescope can be aimed at a lower altitude, the atmospheric drag, will cause the telescope to slow down and eventually burn up in Earth's atmosphere.
However, considering the importance and the sensitivity of the Hubble telescope, moving it into a safer orbit would require careful planning and execution to minimize any potential damage to the spacecraft and its instruments."
