Re: Fixing Hubble's optics
Cool article Henk!
Yeah, I remember that well. I worked with a guy from P-E. He said that initial, NASA reported that the mirror was ground incorrectly, where actually, it was not measured correctly.
One of the biggest technological project of my lifetime. And, there has been many!
Thanks!
