More evidence there was a joint USA-USSR mission to Mars in 1972! Pshh, like you needed more evidence.

All around the interwebs the past few years there have been videos and other things leaked out which seem to suggest the rumors of a joint USA-USSR mission to Mars are true. Any logically-minded skeptic would wonder why they would keep something like this secret. There are a few different reasons.
One is that this trip would have been expensive. By the USA-USSR joining forces, costs would be cut significantly.
Another is the possibility of something going wrong. Any bad publicity surrounding a Mars voyage would put a very sour taste in the publics' mouth.
We cannot forget that this is alleged to have occurred in 1972, during the Cold War. Had the American public discovered we were doing anything whatsoever in collaboration with the Soviets, they would have been pissed.
Finally, and perhaps the most important reason to keep a mission to Mars secret, would be because they wanted to keep what they believed they were going to find on this trip a secret. What could be so important on Mars' surface to hide from the public of the Earth?
A frickin' shitload. That's what.
We can get into that more in a later post.
