Soon a problem was discovered mirror in the telescope was the wrong shape, so the pictures were fuzzy. Astronauts on the space shuttle Endeavour were sent to fix the telescope in space . In five space walks, the astronauts changed the telescope's camera and added another set of mirrors. Since then, the Hubble Telescope has been taking amazing, clear pictures of the solar system.

Answer
The main or central idea of the passage is that astronauts fixed a problem with the Hubble Space Telescope in outer space. The passage describes how the Hubble Space Telescope, after being positioned in space, was found to have a problem with its main mirror that caused it to take fuzzy pictures. It then details the solution to this problem, which involved astronauts repairing the telescope by changing its camera and adding a new set of mirrors during spacewalks. This repair allowed the telescope to take clear pictures of the solar system thereafter.
