1. The mirror is curved. Check out the image of the grad student and the LT in the mirror. Their heads are larger than the professor near the mirror. Therefore, the image is magnified and the mirror must be curved. Second, pay attention to the doorframe (or whatever it is) behind the LT. There is a slight curvature in it.

2. The article mentions that the surface is smooth to a millionth of an inch. That works out to roughly lambda/4, which is optical quality for most applications (but not good enough for really good astronomical optics).

3. Pardon me for shouting, but WHAT THE )(*&%^_()&&*%_) IS HE DOING WITHOUT GLOVES ON!!!! You don't mess with high quality optics without gloves, masks, smocks, and a clean environment. We treat our sounding rocket optics better than that...

My job involves designing space optics, so I'll be following this news closely. Heck, I'm working on a 1-meter telescope design right now...
