Dearest Lineofsight-ologists,

As a sheepy I of course have many friends and fans far and wide across the Earth...which is nice !!...yep...from all over the globe my chums be there .


If I wanted to could I launch a mirror into space and with the aid of a telescope see my chums ?

As a firm believer in empirical study this is how I think it can be achieved !!


Drawn To Scale !

Nice eh?

whajafink ? can it be done ? Can I See A Friend Across The Earth With A Telescope & An Orbiting Mirror ?

If this is possible then I plan to set up a 'Pay-As-Ewe-See' system where all my friends and fans can pay to see me at mutually convenient times  (but mostly at MY convenience)

Thanks for sharing your thoughts on this

Hugs  & Shmishes



mwah mwah mwah !!



Neil
I Iz Tourist Attraction

The view from your orbiting mirror would be that of a spy satellite.

The optical path shown is travelling through a lot of atmosphere which will blur the image.

The blurriness towards the end of this video of the ISS viewed from Earth gives an idea of how poor the resolution would be.

On your diagram your hypothetical satellite is about a half Earth's radius above Earth's surface,
 i.e. at an altitude of  ~3000Km, the ISS is only at ~300Km.

If your friend was antipodal your hypothetical satellite would have to be infinitely far away.
