Hello Friend,

Well that's a very good question.

And depends on who you might be sending. 

Jian Ghomeshi?  Bill Cosby?

Just a thought.

Now, I don't have the answers, but if you want to find out more, then you might want
to attend this Toronto lecture on Friday November 21st.

Hosted by our friends at the Astronomy Space and exploration Society, (ASX)  University of Toronto.

You'll find more information right here:

Clear Skies,

PS On the other hand, if you just want to observe Mars through your telescope, 
  the bigger the telescope, the more you will see.
  And if you need help in that department, we are always here to assist you.  www.khanscope.com
  right now, we've got a whole lotta stuff on sale.

PPS The other day I asked you if you've had enough of winter already. Dang, I just realized it hasn't even
        officially started yet, not even in Buffalo, New York, where I'm sure my buddy Eric Briggs is have
        a rather forlorn look at the shovel in his hand. :(
