Ancient Orbiter 4B

The 1977 Viking Mission to Mars reveals its real objective. To intercept & explore the transmission coming from an unknown location on Mars known only as Ghost Station 6. Scientists believe a portal to a 6th dimension is leaking signal from Cydonia. The entity communicates through sound and these are classified recordings of the contact as the probe descends to the Mars surface before losing contact. Scientists believe the probe teleported to Saturn before disappearing into a catastrophic sound wave.
