When Kodak had ground a back-up mirror for Hubble, it might have been extremely hard to replace the mirror in orbit, and also expensive and time-consuming to carry the telescope back again to Earth for your refit.

Meade justifiably prides by itself about the laboratory-grade heritage of its optical elements and meticulous machining. Indeed, the clear mild-transmission Homes of this StarNavigator 102 are superb, resulting from to some degree much better glass casting and lens coating than competitors.

Even though the Hubble observatory is nearing the top of its lifetime, there remain key projects scheduled for it. A single illustration could be the approaching Frontier Fields method,[102] motivated by the results of Hubble's deep observation in the galaxy cluster Abell 1689.[103]
