From the beginning Hubble Space Telecscope was designed with logistics in mind. Hubble is modular and astronaut-friendly. Its component modularity allows NASA to equip Hubble with new, state-of-the-art scientific instruments periodically, giving the telescope new capabilities with each servicing mission. With every servicing mission, Hubble becomes a new, state-of-the-art telescope at a fraction of the cost of building one 'from scratch'. Servicing missions also enable returned Hubble hardware to be refurbished and reused, saving money. Two examples are the optical bench for the ultraviolet instrument, the wide field camera 3, the fine guidance sensors. Hubble's modularity and its ability to be serviced allowed several critical repairs to be made that were not on the original servicing schedule, the most famous being the correction of Hubble's fuzzy vision. Another example of the advantages of serviceability occurred when astronauts retrofitted an existing but dormant Hubble instrument called the Near Infrared Camera and Multi-Object Spectrometer with a new, experimental cooling system to return it to active duty.
