NASA is putting pause on sending commands to its Mars exploration instruments from November 11 through November 25 as it waits out the Mars solar conjunction. With the sun in the way, any commands sent to Mars could suffer interference capable of harming the robotic explorers.

      Is this a reference to young lovers of Victorian England communicating via encrypted messages via the personal columns in newspapers?

      These “agony columns,” as they became known, provoked the curiosity of cryptanalysts, who would scan the notes and try to decipher their titillating contents. Charles Babbage is known to have indulged in this activity, along with his friends Sir Charles Wheatstone and Baron Lyon Playfair, who together were responsible for developing the deft Playfair cipher (described in Appendix E).

      On one occasion, Wheatstone deciphered a note in The Times from an Oxford student, suggesting to his true love that they elope. A few days later, Wheatstone inserted his own message, encrypted in the same cipher, advising the couple against this rebellious and rash action. Shortly afterward there appeared a third message, this time unencrypted and from the lady in question: “Dear Charlie, Write no more. Our cipher is discovered.”
