Being born in the very early 1970s isn't good for much, but reminiscing about 300 baud acoustically coupled modems, and talking about the Soviet space program are two exceptions. ;-)
> A suite of instruments more sensitive than those on Mariner 2, in particular its radio occultation experiment, returned data on the composition, pressure and density of the Venusian atmosphere.[102] The joint Venera 4 – Mariner 5 data were analyzed by a combined Soviet-American science team in a series of colloquia over the following year,[103] in an early example of space cooperation.[104]
You can bet your skippy that if ever someone steps foot on Mars, there will be books, conspiracies, movies, etc.
Coverage was there, for those who were interested in finding it. The Soviets' failures were, of course, highlighted, but their accomplishments weren't downplayed, either.
