> It's hard to overstate the importance of the Hubble. It empowered physicists to prove that the universe is not only expanding but accelerating in its expansion (commemorated in the 2011 Nobel Prize). Its beautiful images also captured the popular imagination of people, inspiring myself and others to pursue scientific careers. It's doubly important to realize that for the first few years, Hubble was deemed a failure. It was mocked in the newspapers and by late night comedians - but it was fixed, the program was recovered, and now it's hard to think of a world without it. (Even though that world will be here soon.)
