Life on Mars, Hoax or Conspiracy Theory? or Why we can’t believe anything NASA says!

There’s a lot to see in this screen-capture. First, in the upper left is the NASA website: https://photojournal.jpl.nasa.gov/catalog/pia16204 where the photo in question can be downloaded. Second, The rodent at the bottom of the screen is an unedited magnification of NASA’s photo PIA16204. Its frame’s upper left hand corner points to the approximate location of the zoomed in location on the NASA’s thumbnail of PIA16204. Lastly, toward the upper right you will find an image from a “debunking” story on buzzfeed: https://www.buzzfeed.com/ishmaeldaro/mars-rover-hoax-conspiracy-theory . Now if you still believe these liars produced live TV transmissions from the moon in the 1960’s, it might say more about you than them. Acceptance of reality can only begin by displacing the lies we’ve all been indoctrinated to accept. Break the spell: https://www.aulis.com/

Gottlieb EM Pinball Tip: Inconsistent ‘Add Player Unit’ operation.


Check contacts at Extra Ball Relay, Z1, Z2, 1st Ball Relay, Motor 1A and Add Player Relay… All Good!
Turns out it was the “Hole Switch” Bouncing at the same time as the “Trough Switch” was being activated causing enough voltage drop to fail to trip the Add Player Relay.
