THis... is wrong... because you would only be able to see the present, right? Due to the equal travel time to and from the mirror?

You could see the past, but -- unless the mirror traveled FTL -- the earliest time you could possibly see is when the mirror left earth.

(Of course, we're always looking into the past. Light travels at about one foot per nanosecond.)

But you'd still have a "live" view of the past, so we could think back on the good old days when we were completely fucked.
