Those of us within reach of the LA Times were treated to the following
explanation (reprinted below in its entirety) in an illustrated sidebar to
a Hubble repair mission story on page 1 last Friday. The sidebar was
entitled "How Hubble Works."
"Light enters telescope and bounces off mirrors. Then it shines on
science instruments through a hole in the center of the primary mirror."
