| The Hubble Space Telescope, free of the distorting effects of the earth’s atmosphere, has an unprecedented view of distant galaxies. Placed in orbit in 1990, scientists discovered soon after the telescope became operational that its 240-cm (94.5-in) primary mirror was flawed. However, a repair mission completed by space shuttle astronauts in December 1993 successfully installed corrective optics which compensated for the flawed mirror. | ||||||
