However prior to the mission, on June 1990 a few months after the Hubble Space telescope was launched, NASA discovered a problem with space telescope. Scientists found out that the space telescope’s primary mirror of the two on the telescope had a spherical aberration. This spherical aberration meant there was an optical problem involving the light coming in to the telescope. This caused problems for the telescope because the mirrors were the “eyes” of the telescope called the Optical Telescope Assembly. This resulted in the images provided by the Hubble Space telescope to be blurry caused by the angle of the incoming light. NASA responded by installing the COSTAR (Corrective Optics Space Telescope Axial Replacement) allowing the primary mirror to correct the errors of the lighting. The COSTAR installation was successful and fixed the Hubble Space telescope’s blurry vision by installing five pairs of corrective mirrors.

Wide Field and Planetary Camera 2 (WFPC2)

Another important installation on the Hubble Space Telescope was the WFPC2 (Wide Field and Planetary Camera 2). The WFPC2 replaced the older WFPC improving the space telescope performance by “incorporating advanced detectors and a built-in corrective optics system.” The WFPC2 was the main camera of the space telescope providing many famous pictures of space still used today such as the Eagle Nebula and Spiral Galaxy NGC 4414. It was created to record images of

    The telescope has changed the world greatly by being able to make distant objects appear closer and more distinct. It helped scientists to discover things that could not be seen by the naked eye. For example, a lot of things in space would have not been discovered if it were not for the telescope. Also, it helped the world of eyesight. It would not only let you see objects from far away, it would also help you see if you had a problem with it. It could also be used for other things: hunting, war
