How do you beat the bonus quest on lunar colony island?

Answer 1

The BONUS QUEST is for paid monthly members only:

1) More messages in code are received from the SETI array, and you are tasked to find Dr. Alan Turing, an expert cryptanalyst (a real person, Turing lived from 1912 to 1954).

2) Return to the PASE entrance and go left to take the bus marked Silver Shuttle. At the Retirement Home, click on the name "Grant Luina" on the call buttons until it re-arranges to spell Alan Turing.

3) Talk to Turing and return to Mission Control.

4) For each of the messages, you only need to add the alphabet letters to the symbol diagrams in order.

A thru I on the #

J-K-L-M on the first cross

N thru V on the next #

W-X-Y-Z on the second cross

The coordinates allow the SETI receiver to pick up 4 different images transmitted from the alien world.
