Todd M. Tripp, University of Massachusetts. TODAY, 9PM. PBS. Program synopsis: “. But Hubble's early days nearly doomed it to failure: a one-millimeter engineering blunder had turned the billion-dollar telescope into an object of ridicule. It fell to five heroic astronauts in a daring mission to return Hubble to the cutting edge of science. . Ron Maddalena. July 2013. Typical Components. Amplifiers. Mixers. Attenuators.
