What Makes Hubble Different From Telescopes on Earth? where it can become distorted and manipulated. An investigation finally revealed a spherical aberration in the primary mirror, due to a miscalibrated measuring instrument that caused the edges of the mirror to be ground slightly too flat. The main reason for examining these pros and cons is to determine whether or not a space telescope is really needed in this day and age. Among the many technological advances used in the telescope's construction was the computer-based laser grinding system used by Perkin-Elmer to craft the observatory's primary mirror. example. Telescopes have come a long way since those earliest telescopes from Europe. Earth's atmosphere obscures our view of space, so we put satellites, like the Hubble Space Telescope, above the atmosphere to see better. What are three types of Earth based telescopes? Still, Earth's thick atmosphere and its rippling interference kept even the best ground-based telescopes from seeing more clearly. The Hubble Space Telescope travels through space with Earth in the background in this picture, taken after the fourth servicing mission in 2002. The telescope also would have to be placed far away from city lights to minimize interference with the lighting conditions of the telescope. Columbia crewmembers installed the new Advanced Camera for Surveys (ACS), which had sharper vision, a wider field of view, and quicker data gathering than the Wide Field/Planetary Camera 2. The first advantage is that the HST is above the atmosphere, which enables it to observe in the ultraviolet, visible, and infrared regions of the electromagnetic spectrum. Scientists and engineers must take different physical factors into consideration when finding a suitable location to place a ground-based telescope.
