Why do you think it will be low in the sky?

Will this reflector tumble or be stabilized?
If it's a corner reflector - it could have gain in some direction.
My guess is that this size object would reflect 2M signals and up.
The moon is bigger but only reflects 7% of RF energy and it's much farther away.
I'm sure someone will try to bounce an RF signal off this mylar sail.
It should be easy to see from the ground. :) But very low in the sky.

It says once opened it will " It will span 16 square meters (170 square feet)" a Triangle one side of 170 sqft = 18 feet base to peak. But if they are saying 170 sqft total, then divided by 3 = 10 foot tall base to peak. Now for a surface to be reflective, how big does it need to be in terms of wvelength?
