In fairness to the Sci-Fi writers, we've launched so many probes into deep space since then.

We've sent satellites to Jupiter and diving bells below the clouds of Venus. We've retrieved soil from Mars and sent signals from beyond the Ort Cloud. We've recorded Gravity Waves and captured light off the edge of Black Holes and recorded the touch of Neutrinos.

We don't have six guys drinking coffee and staring out a window overlooking the moon of Titan. But that is largely because our signaling and robotics has made automated exploration more practical than manned missions.

And also because SciFi writers of the 1950s didn't understand how much radiation humans would need to shield themselves against once they left the Earth's magnetosphere.
