I have to plead ignorance here. How does one “SEE” anything through a dish antenna? I guess if one can be happy watching squiggly lines on an oscilloscope it might be exciting, a la, Jodie Foster in the flick, “CONTACT.” But a 2 meter dish is NOT a telescope wherewith one can VIEW anything. What am I missing here?
The things we wish to see are beyond visual range. Many of the astronomy photos you see are from 'radio-telescopes' (dish antenna).
Another reason for the radio-telescope is that 'dust' doesn't bother it like it does an optical telescope.
We're all joking about an optical telescope on here because we're JUST SO HAPPY that someone wants to put ANYTHING on the MOON.
: )
I believe the dish is for radioing the data stream of digital images from the lander back to earth.
The image in the article prominently features the dish antenna on top of the lunar lander, but doesn't show the actual telescope. The specs for that are here: https://app.box.com/ilox-faq
