When the Hubble telescope was first launched, it sent back blurry images. It turns out that the primary mirror, an object 2.42.4 m in size, was ground down, along the edge, 2 microns too thin. That's one millionth of one meter too thin! That difference caused the telescope to focus only 10%-15% of a star's light, when it was supposed to gather 70% of a star's light into the focal point. NASA had to send another manned mission to space to fix the telescope at an estimated cost of $1.5 Billion!!
